About Convert Image Format
The Convert Image Format tool re-encodes a picture from one format to another without ever sending it to a server.
Drop in a PNG, JPG, WebP or GIF and choose the format you actually need: PNG for crisp graphics and transparency, JPG for small, widely-compatible photos, or WebP for the best balance of quality and size on the modern web.
Each format has trade-offs, and this tool makes them easy to feel.
PNG is lossless, so it preserves every pixel and any transparent areas, but the files can be large.
JPG and WebP are lossy: they discard detail you are unlikely to notice in exchange for dramatically smaller files, and a quality slider lets you decide exactly where on that curve to sit.
The live preview and encoded-size readout update as you tweak, so you can see the result before you commit.
Because the conversion runs entirely on your device through the Canvas API, your image is never uploaded, stored or logged — ideal for screenshots, private photos or client assets — and it keeps working offline once loaded.
When the preview looks right, download the converted file with the correct extension applied automatically.
FAQ
Is my image uploaded to a server?
No. The file is decoded and re-encoded with the Canvas API inside your browser, so it never leaves your device.
Which format should I choose?
Use PNG for graphics and transparency, JPG for broadly compatible photos, and WebP for the smallest modern files at good quality.
Why is there no quality slider for PNG?
PNG is lossless, so it ignores a quality setting — every pixel is preserved exactly.
