To rasterize a layer in Photoshop, right-click it in the Layers panel and choose Rasterize Layer (for type, choose Rasterize Type), or use the menu at Layer > Rasterize. This converts the layer’s editable vector or text data into fixed pixels so you can paint, erase, and run filters on it.
Duplicate the layer before rasterizing so you retain an editable original. This guide explains the menu commands, what becomes pixels, and how to diagnose an unavailable command.
- Duplicate the editable layer and keep the original.
- Select the copy and leave text-editing mode if necessary.
- Choose Layer → Rasterize → Type, Shape or Smart Object for that layer, then inspect the resulting pixel layer.
Tested layer examples and working file
These original captures were made in Photoshop 2026 27.11.0 on macOS 26.6, using a new 2100 × 1500-pixel RGB/8 document. We created live type and a shape, duplicated them, and rasterized the copies. We also converted a duplicate to an embedded Smart Object, preserved it and rasterized a further copy.
Download the layered PSD example (ZIP). The layers are deliberately stacked for comparison: toggle visibility and select each layer to inspect its type. Watch the captioned capture sequence (MP4); this video presents the recorded screenshots rather than a continuous screen recording.
The menu reference is Adobe’s rasterize-layers documentation, updated September 28, 2026. The Windows commands are documentation-based; this session tested macOS.
What Does Rasterize Mean in Photoshop?
Rasterizing converts a vector or text layer into a normal pixel-based layer. A vector shape or type layer retains editable shape or text information that can be rendered at a new size. Rasterizing turns that math into a fixed grid of pixels, the same as a photo. You gain pixel tools and lose the ability to edit the text or scale the shape without quality loss.
When You Should (and Should Not) Rasterize
Rasterizing removes the selected layer’s editable source data, so preserve a copy before using a tool that requires pixels. Before you commit, ask whether converting the layer to a Smart Object (right-click the layer and choose Convert to Smart Object) would let you work non-destructively instead. When you do need pixels, these are the real reasons:
- You want to use a pixel-painting tool on the layer: Brush, Eraser, Paint Bucket, Clone Stamp, Smudge, or Dodge and Burn. These cannot touch a live vector, type, or Smart Object layer.
- You want to run a standard filter on a plain (non-Smart) vector or text layer. The non-destructive alternative is to convert the layer to a Smart Object first and apply the filter as a Smart Filter.
- You want to merge a vector or text layer into a pixel layer, or paint across several layers as one.
One common myth worth clearing up: you do not need to rasterize to add a layer style. Drop shadows, strokes, bevels, and glows all apply to live type, shape, and Smart Object layers through the fx icon, and your text stays editable.
How to Rasterize a Layer in Photoshop
Supported editable layer types have two access points: a right-click in the Layers panel, and the Layer > Rasterize menu. Available submenu items depend on the selected layer and installed version; use the item for your layer type.
Rasterize a shape or vector layer
- In the Layers panel, select the shape or vector layer.
- Right-click the layer’s name or thumbnail and choose Rasterize Layer (it reads Rasterize Layers if you have two or more selected).
- Menu equivalent: Layer > Rasterize > Shape (or Layer > Rasterize > Layer). The shape becomes a normal pixel layer.
Rasterize a text (type) layer
- Finalize your wording and font first, because you cannot edit the text after this.
- Right-click the type layer in the Layers panel and choose Rasterize Type. That is the whole job: one step.
- Menu equivalent: Layer > Rasterize > Type.
Skip the old “Convert to Shape first” advice you may have seen. Convert to Shape does the opposite of what you want here: it turns your text into a vector shape, which is still not pixels. Only use Convert to Shape when you want to keep the text scalable as vector artwork.
Rasterize a Smart Object
- Select the Smart Object in the Layers panel.
- Right-click and choose Rasterize Layer, or use Layer > Rasterize > Smart Object (Layer > Smart Objects > Rasterize does the same thing).
- This flattens the embedded source and bakes in any Smart Filters and transforms, so do it last.
Rasterize every layer at once
To flatten all vector and generated data in one action, use Layer > Rasterize > All Layers. Layer > Rasterize > Layer handles only the selected layers. There is no right-click command for “all layers”; it lives on the Layer menu.
The “This Layer Must Be Rasterized” Prompt
Most people first run into rasterizing through a warning box. The moment you grab the Brush, Eraser, or Paint Bucket on a vector, type, or Smart Object layer, or try to run a filter on a plain vector or type layer, Photoshop stops you with a message like “This type layer must be rasterized before proceeding. Rasterize the type?” A filter applied to a Smart Object becomes a Smart Filter instead, with no prompt.
- Rasterize converts the layer to pixels on the spot so your tool works, but the change is permanent.
- Cancel backs out. If you are not sure, cancel, then duplicate the layer or convert it to a Smart Object before you continue, so you keep an editable version.
Why is Rasterize greyed out?
| Selected content | Next step | Verification |
|---|---|---|
| A regular pixel layer | It is already rasterized. Check whether the editing tool has a separate lock or selection problem. | Observed in the demonstration: Type, Shape, Smart Object and Layer rasterization were unavailable on the resulting pixel layer. |
| A live type or shape layer | Select the layer thumbnail, leave text editing, then use the matching Rasterize command. | Type and Shape commands executed in the demonstration. |
| A Smart Object | Duplicate it, then choose Layer → Rasterize → Smart Object if pixels are actually required. | Executed in the demonstration. |
| A mask, group, Background layer or no selection | Inspect what is selected. Unlocking can enable editing but does not turn an already-pixel layer into vector content. | These additional states were not reproduced in the current test. |
How to Undo Rasterizing
Undo or an available History state can return to the earlier layer while that history remains. A preserved editable layer, backup or suitable version history can also restore the source. Saving only the rasterized copy does not preserve type, vector or Smart Object editability; keeping an original copy before the conversion is the dependable workflow.
Because there is no true “un-rasterize,” protect yourself before you convert. Duplicate the layer and hide the copy, or convert to a Smart Object instead of rasterizing, so the editable original is always one click away.
Rasterize vs Flatten vs Merge vs Smart Object
These four commands all sound similar, and people mix them up constantly. Here is what each one actually does:
| Command | What it does | Layers after | Reversible in session |
|---|---|---|---|
| Rasterize | Turns one vector or type layer into pixels | Stays a separate layer | Yes (History only) |
| Merge Layers | Combines selected layers into one pixel layer | Fewer layers | Yes (History only) |
| Flatten Image | Merges everything into a single background layer | One layer | Yes (History only) |
| Convert to Smart Object | Wraps the layer so edits stay non-destructive | Stays editable | Yes, edit anytime |
And here is how a vector layer compares to the same layer after rasterizing:
| Attribute | Vector or type layer | Rasterized layer |
|---|---|---|
| Editing | Text and shapes stay editable | Fixed pixels only |
| Scaling | Can be re-rendered at another size; document and effects still matter | Pixelates when enlarged |
| Pixel tools (brush, eraser) | Not allowed | Allowed |
| File size | Depends on content and compression | Depends on content and compression |
Photoshop has no default keyboard shortcut for Rasterize, but you can make one. Go to Edit > Keyboard Shortcuts, find Layer > Rasterize > Layer, and assign a key combination. Alternatively, record the command as an Action and bind that Action to a function key.
Pros and Cons of Rasterizing
Pros
- Lets you use pixel-painting tools like the Brush, Eraser, Paint Bucket, and Clone Stamp.
- Lets a plain vector or text layer accept standard filters directly.
- Gives you full pixel-level control for detailed retouching.
Cons
- Text and vectors are no longer editable.
- The layer pixelates if you scale it up later.
- File size can increase or decrease. Rasterizing a Smart Object can remove its embedded source data; compare saved copies rather than assuming a universal size change.
- A Smart Object’s Smart Filters and transforms get baked in permanently (plain layer styles stay live until you merge or flatten).
Rasterize at the intended output size and inspect fine edges. Enlarging later can expose the fixed pixel grid; the result also depends on the source, document settings and effects.
Frequently Asked Questions
What is rasterization in Photoshop?
Rasterization converts a vector or text layer into a pixel-based layer. Photoshop replaces the layer’s math-based data with a fixed grid of pixels, which lets you use pixel tools and filters but ends the layer’s editability and lossless scaling.
How do I rasterize a layer in Photoshop?
Right-click the layer in the Layers panel and choose Rasterize Layer, or Rasterize Type for a text layer. You can also use the menu at Layer > Rasterize and pick the layer type you want to convert.
Do I need to rasterize a text layer to add a drop shadow?
No. Layer styles such as drop shadows, strokes, and bevels apply to live type layers through the fx icon, and the text stays fully editable. You only need to rasterize when you want to paint on the text with a pixel tool or run a standard filter on it.
Why is Rasterize greyed out in Photoshop?
Check the selected layer type first. A regular pixel layer has nothing to rasterize. Locks and selected masks can affect editing, but unlocking is not a universal rasterization fix.
Can you undo rasterizing in Photoshop?
Undo (Command+Z on Mac, Ctrl+Z on Windows) or an available History state can restore the earlier layer while that history remains. A retained original layer, backup or suitable version history can also recover it. Saving a rasterized copy alone does not preserve the original editability.
Does rasterizing reduce image quality?
Rasterizing fixes the appearance at the current pixel resolution and removes the source layer’s editability. Inspect fine edges at the intended output size; later enlargement cannot recover the original vector or type information.
What is the difference between rasterize and flatten?
Rasterize converts a single vector or type layer to pixels while keeping it separate. Flatten Image merges every layer in the document into one background layer. Rasterize affects one layer; flatten collapses the whole file.
Can I convert a raster image back to a vector in Photoshop?
Not directly. Photoshop can only build rough paths from a selection and has no true auto-trace, so genuine raster-to-vector conversion is better handled in a vector program like Adobe Illustrator. This is why keeping an editable copy before rasterizing matters.
Rasterize only the part that needs pixels
The Rasterize menu contains more specific operations than “make this entire layer pixels.” Adobe distinguishes Fill Content, which rasterizes a shape’s fill while retaining its vector mask, from Vector Mask, which turns that mask into a pixel-based layer mask. Layer converts the selected layer’s vector or generated content, while All Layers applies to eligible content throughout the document. These options are documented in the Rasterize menu reference; the additional mask operations were not part of the example-file test above.
Choose the narrowest operation that solves the problem. If you only need to hide part of a title, a layer mask lets you paint its visibility while retaining editable type. If you only need a new fill color, change the type or shape color. Neither task requires destroying the text or path information.
Worked choice: make a distressed title and keep the wording editable
- Create the title as a type layer and save the document in a format that retains layers.
- If the distress is simply missing patches, add a layer mask to the type layer and paint the mask. Select the mask thumbnail before brushing.
- If your desired operation truly requires painting the letter pixels, duplicate the type layer, hide the original and rasterize the duplicate.
- Name the layers clearly, for example “Title — editable” and “Title — painted pixels.”
- Inspect the title at the final output size. If the wording changes later, return to the editable layer and repeat only the effect that depended on the old letters.
The distinction is where the brush works: painting a mask changes visibility, whereas painting the rasterized layer changes image pixels. Adobe’s rasterizing overview recommends masks, new layers and Smart Objects as alternatives for suitable tasks.
A Smart Object is not automatically vector artwork
As Adobe’s Smart Object overview explains, a Smart Object can preserve raster or vector source content. Wrapping a low-resolution photograph in a Smart Object does not create unlimited detail. Its benefit is preserving the source and editable transformations or supported filters while you work. Rasterizing commits the current result to pixels; the original source’s resolution still matters.
Why is the layer still difficult to paint after rasterizing?
Check the editing target separately from the conversion. Confirm that the pixel thumbnail, rather than a mask, is active; inspect the layer’s visibility and locks; and check whether a selection restricts the area you can paint. These are diagnostic checks, not promises that every grayed-out command has the same cause. If a brush stroke is invisible, making an already-pixel layer “more rasterized” will not resolve a hidden layer or the wrong target.
The One Habit That Saves You
Rasterizing itself is one right-click. The skill is knowing when not to. Before you convert a layer, ask whether a Smart Object would keep your work non-destructive and get you to the same result. When a tool truly demands pixels, duplicate the layer first, rasterize the copy, and keep the editable original in your back pocket. That single habit will save you from redoing type and shapes more times than any shortcut ever will.
