Change canvas size in Photopea
How to expand or trim the canvas in Photopea without scaling your logo, plus how canvas size affects shape layers, text and SVG or PNG export.
Contents
The short answer
In Photopea, the canvas is resized from the Image menu with the Canvas Size command. It is the same command found in Photoshop, and Photopea typically uses the same keyboard shortcut, Alt+Ctrl+C on Windows or Option+Cmd+C on a Mac. The dialog lets you set a new width and height and pick an anchor point that controls which direction the canvas grows or shrinks. Your logo stays at its current size. Only the working area around it changes.
This differs from Image Size, which is also in the Image menu. Image Size scales the whole document, artwork included. If you want more space around a logo, such as padding for a social media avatar or a square format for a favicon, use Canvas Size. If you want the logo itself larger or smaller, use Image Size or transform the layers directly.
What canvas size means for a vector logo in Photopea
Photopea is a browser-based editor that handles both raster and vector content. It can open SVG files and many PDF, AI and EPS files. When a vector file is imported, its shapes usually become shape layers with editable paths, and its text may stay live if the fonts are available. How well this works depends on how the file was built. A file with an .svg or .ai extension is not proof of editable vector paths. It may contain only an embedded bitmap or a flattened raster preview. Before you resize, check the Layers panel and look for shape layers, text layers or smart objects, as opposed to plain pixel layers.
Changing the canvas does not alter vector paths or pixels. It changes the document bounds. Those bounds become the visible area of any PNG or JPG you export, and the page or viewBox dimensions of an exported SVG or PDF.
| Task | Command to use | Effect on the logo artwork |
| Add padding or change aspect ratio | Image > Canvas Size | None; only the document bounds change |
| Make the whole document larger or smaller | Image > Image Size | Everything is scaled; raster layers are resampled |
| Cut away empty or transparent margins | Image > Trim, or the Crop tool | Artwork is untouched; surrounding area is removed |
| Resize only the logo inside the canvas | Free Transform on the selected layers | Selected layers are scaled; the canvas stays the same |
How to change the canvas size step by step
Start with the logo file open in Photopea. If you also need a deliverable for a client or a platform, have its target dimensions or aspect ratio ready. No exact sizes are given here because requirements vary by platform and change over time.
- Open the logo with File > Open, or drag the file into the browser window.
- Check the Layers panel to confirm which parts are vector shapes, live text or raster images.
- Go to Image > Canvas Size.
- Choose a unit, such as pixels or percent, and enter the new width and height.
- Click a square in the anchor grid. The center square expands the canvas equally on all sides. An edge or corner square keeps the artwork pinned to that side.
- Confirm with OK.
- If the logo needs to sit in a new position, select its layers and use the Move tool or the alignment options to center it.
The newly added area may be transparent, or it may be filled with a color. This depends on the document, for example whether it has a locked background layer. Check the result as soon as you resize. If you need a transparent background for a logo, unlock or remove any solid background layer, then confirm that the checkerboard pattern shows in the new margins.
Export settings that depend on the new canvas
The canvas determines the frame of every export, so choose the format based on how the logo will be used:
- PNG: keeps transparency and is suitable for web and app placements. The exported pixel dimensions match the canvas.
- JPG: has no transparency. Transparent margins will be filled with a solid color.
- SVG: shape layers and supported text can be exported as vector elements. The canvas size sets the drawing area. Any raster layers are embedded as images, so they will not become scalable paths.
- PDF: useful for print handoff when the vector content is preserved. Open it again to confirm that the paths stayed vector.
Final check before you hand off the file
- The logo has not been scaled or distorted, and it is centered or anchored as intended.
- The margins are transparent or filled correctly for the target use.
- Shape and text layers remained editable and were not rasterized during editing.
- Exported files have the expected dimensions. An exported SVG reopens with paths rather than a single embedded image.
- Fonts used in live text are licensed for the intended use, or the text has been converted to shapes where licensing allows.
Being able to download a logo file does not mean you have permission to modify it. Changing the canvas or padding of a third-party brand mark is still modifying the artwork, so check that the owner's brand guidelines or license allow it. Trademark rights and font licenses apply separately from the file itself.
Known gaps
This guide was written without confirmed documentation for the current version of Photopea. Menu names, shortcuts and dialog options are based on Photopea's long-standing Photoshop-style interface and may change between updates. If a label differs from what you see, look for the equivalent command under the Image menu. Import fidelity for AI, EPS and complex PDF files was not verified here, so inspect each imported file rather than assuming its layers are fully editable.
