PNG vs JPG vs WebP: which format should you export?
Use Export in the top bar for a finished picture. Use Save project for the editable JSON file. These downloads serve different purposes.
Choose the file you need
| File | Use it for | What changes |
|---|---|---|
| PNG | Transparency, text and sharp edges | Visible layers become one image; photographs may be large. |
| JPEG | Photos with an opaque background | Lossy compression; transparent areas become white. |
| WebP | Web images where the destination accepts it | Supports transparency; check that the receiving site accepts WebP. |
| JSON project | Continuing this edit | Keeps editable layers and settings; not an image for an upload form. |
| PSD | Exchanging supported layers | 8-bit RGB exchange with compatibility limits; keep the original. |
Export with a preview
- Check the active canvas tab, its dimensions and the visible layers. Export uses that canvas, not every open tab.
- Choose Export, select the format and, for JPEG or WebP, adjust quality. Wait for the preview and encoded file size.
- Choose Download image. Open the downloaded file and inspect edges, text and transparency.
- Save a separate JSON project if you need to revise the layers. Save each open canvas separately.
White background or unexpectedly large file?
Choosing PNG does not remove a background that is already part of the image. Remove or mask that background first, and enable document transparency. JPEG always uses white behind transparent pixels.
For a smaller file, first reduce unnecessary pixel dimensions, then compare JPEG or WebP quality. PNG has no quality slider here. Repeated JPEG exports can accumulate damage; make new exports from the project or original.
