When to use PNG to JPG
You took a screenshot of a filled-in form, and the PNG is 4 MB — too big for the email attachment limit your HR portal enforces. Drop it here and Canvas compresses it to JPG, typically cutting the file to a fifth of its original size. Transparency is flattened to white, which is exactly what you want for a document screenshot. The conversion happens in the browser tab, no account needed. You get a JPG that uploads instantly, attaches to a Gmail thread without a size warning, and looks fine in any PDF viewer. Reach for this whenever you have a UI screenshot, mockup export, or scanned receipt that needs to travel light.
- Flatten a UI screenshot for an email attachment under 1 MB
- Shrink a scanned receipt before uploading to an expense report
- Compress a Figma export before posting to a Notion page
