About the formats
- PNG — lossless and supports transparency. Best for logos, icons, screenshots, and graphics with sharp edges.
- JPG — lossy with smaller files and no transparency. Best for photographs.
- WebP — a modern format that's usually smaller than PNG or JPG at similar quality, and supports transparency.
Frequently asked questions
What does the quality slider do?
It controls compression for the lossy formats (JPG and WebP) — lower quality means a smaller file. PNG is lossless, so the slider doesn't appear when you convert to PNG.
Will converting reduce image quality?
Converting to PNG keeps every pixel. Converting to JPG or WebP compresses the image, so keep the quality high if you want the result to look close to the original.
Which format should I choose?
For photos, JPG or WebP give the smallest files. For logos, screenshots, or anything needing a transparent background, use PNG or WebP.
Are my images uploaded?
No. Conversion happens entirely in your browser using the canvas. Your files never leave your device.
