Convert any image format free

Pick a format pair from the grid, then drop a file onto the tool page. The conversion starts the moment the file lands, with no Convert button to click. Most single images are decoded in your browser's memory, rewritten to the new format, and handed back as a download link. The original dimensions are preserved and camera metadata is stripped in the process. Converting to AVIF, or converting several files at once, sends the work to our server, which processes it and shows real progress as each file finishes.

RoundCut works with the four formats the web runs on. PNG keeps every detail without discarding anything and holds transparency, making it the right choice for logos and graphics with sharp edges. JPG compresses photos well and works everywhere, but has no transparency. WebP is the modern format that shrinks the file while keeping visual quality and preserving transparency. AVIF compresses further still at the same quality and has full support in current browsers. GIF works as an input, but only the first frame is used. The grid above shows every pair available today, and new pairs appear as they ship.

It depends on the target format. PNG re-encodes without discarding anything, so every detail of the original is preserved. JPG, WebP, and AVIF compress when they save, and at the default quality setting the difference in a typical photo is hard to notice. Converting an already-compressed source back to an exact format like PNG does not recover what was discarded earlier — it just produces a larger file. If the source has a transparent background and the target is JPG, those areas become solid white because JPG has no transparency channel.

Most single images convert entirely on your device, inside the browser. Converting to AVIF, or converting several images at once, sends the work to our server over an encrypted connection, processes it, and makes the result available to download for about two hours before the link is automatically removed. Those are the paths that upload your file, and you can clear the result yourself at any time. For the full detail on how files are handled, see the privacy policy.

Switch format when something specific calls for it. Use WebP or AVIF when you want a smaller file for a website without sacrificing visual quality. Choose PNG when transparency must stay intact, as for logos and icons where every edge needs to be sharp. Pick JPG when broad compatibility matters more than modern compression, especially for older systems or content platforms that do not yet accept WebP. Avoid running the same image through several compressed formats in sequence, since each pass discards a little more and the result degrades. Convert once, to the format the destination actually expects.

AVIF produces the smallest files of the four formats: a typical photo can come out half the size of an equivalent JPG at the same visual quality. The trade-off is processing time. An in-browser AVIF encode can take several seconds on a desktop and longer on a phone, so converting to AVIF sends the file to our server, where it is generated much faster, and batches go there too. Other single conversions stay in the browser, which keeps AVIF fast on every device.
