Features
Batch conversion
Convert many files at once with a progress counter, powered by Web Workers.
Transparency handling
Keep alpha in PNG/WebP, or flatten onto a color when saving JPG.
Modern formats
WebP output where your browser supports it, and AVIF in browsers that can encode it — unsupported formats are clearly marked.
Clean output
Converted files carry no EXIF or GPS metadata.
Supported formats
Input: JPG, PNG, WebP, GIF (first frame), BMP, SVG, AVIF, plus TIFF/HEIC in browsers that can decode them. Output: JPG, PNG, WebP, AVIF (browser-dependent).
Frequently asked questions
Which formats can I convert to?
JPG, PNG and WebP work in current browsers. AVIF encoding is only available in some browsers; if yours can't, the option is disabled.
Will converting to JPG lose quality?
JPG is lossy, so a small quality loss is possible. At 90% it is rarely visible. Use PNG for a lossless result.
Can I convert animated GIFs?
Only the first frame is converted; animation is not preserved.
Are my images uploaded to a server?
No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
