Change canvas size in Photopea

Changing the canvas size in Photopea, the browser-based image editor modeled closely on Photoshop, adds or removes working area around your artwork. It does not scale the artwork. For logo work this matters: you can add padding, create clear space or fit a mark onto a specific frame without stretching or resampling the logo.

The direct answer

Open the file, then choose Image > Canvas Size. In the dialog, enter a new width and height, choose an anchor point that sets which side the space is added to or removed from, and confirm. Your layers keep their size. Only the document boundary changes.

• Open the logo file in Photopea.
• Go to Image > Canvas Size.
• Enter the new width and height. You can also enable the relative option, if it is shown, to add a set amount rather than typing the final dimensions.
• Click an anchor square. The center square adds space evenly on all sides. An edge or corner square keeps the artwork pinned to that side.
• Check how the new area will be filled. On a transparent document it normally stays transparent. On a flattened background it takes a fill color.
• Confirm, then review the result before exporting.

The steps above follow Photopea's Photoshop-style menu layout. The exact labels, units and options in the dialog can differ between versions, so treat the wording as a guide and check what your copy of the editor shows.

Canvas Size versus Image Size

Command | What changes | Effect on the logo

Image > Canvas Size | The document boundary only | Artwork stays the same size; space is added or cropped around it

Image > Image Size | The whole document and its contents | Artwork is scaled; raster content is resampled and may lose sharpness

Use Canvas Size when you want padding or a different frame. Use Image Size when you want the whole logo bigger or smaller. If you make the canvas smaller than the artwork, anything outside the new boundary is cropped from view. Depending on the layer type, that hidden content may or may not be recoverable later.

What it means for vector logo artwork

A Photopea document can mix three different kinds of content. Vector shape layers are defined by paths. Embedded raster images are pixel-based layers. Raster previews are flattened pixel copies of artwork that may once have been vector. Resizing the canvas does not change any of them. The difference shows up when you scale or export afterward.

• Vector shape layers can be scaled later without losing edge quality while they stay as shapes.
• Embedded raster layers keep their pixel dimensions. Enlarging them afterward will soften or pixelate them.
• A raster preview of a logo cannot be turned back into true vector paths just by adding canvas space around it.

Opening an SVG, PDF or other file in Photopea does not by itself guarantee that you will get editable vector paths. A file extension or filename alone does not prove that a logo contains vector artwork. Some files hold only an embedded bitmap, and some import routes turn content into pixels. Check the Layers panel to see which layers are shapes and which are pixels before relying on vector behavior.

Exporting after a canvas change

The new canvas dimensions become the dimensions of the exported file. If you export as PNG or JPG, everything is flattened into pixels at that size. PNG keeps a transparent background and JPG does not. Photopea also offers SVG export, but an SVG holds true vector paths only for content that was vector in the document. Raster layers are carried inside it as embedded images. If you need a clean, scalable logo file for delivery, confirm that the logo itself is built from shape layers.

Rights and permissions

Being able to download or open a logo is not the same as having permission to modify it, re-export it or use its typeface and trademark. Adjusting the canvas is a minor edit, but redistributing an altered brand mark may still be restricted by brand guidelines, font licenses or trademark rules. Check those terms before you deliver or publish the edited file.

Evidence gaps

No version-specific documentation, measurements or test results were supplied for this article. The guidance above relies on Photopea's general Photoshop-style workflow and on standard principles of vector and raster editing. Exact menu names, keyboard shortcuts, default fill behavior and import handling for particular file types are not confirmed here and should be checked in the current version of the editor.
