Accepts PNG. No size limit, no sign-up.

    PNG keeps every pixel exactly as it was, which is wonderful for accuracy and terrible for file size on photographs. Converting to JPG usually cuts the size dramatically.

    The difference in one sentence

    PNG is lossless: it reconstructs the original pixels perfectly, and it can store transparency. JPG is lossy: it discards information the eye is unlikely to miss, cannot store transparency, and is far more efficient on continuous-tone images such as photographs.

    Neither is better in general. They are good at different things, and the right choice depends entirely on what the image contains.

    When this conversion is a clear win

    Photographs. A camera image saved as PNG is often several times larger than the same image as a high-quality JPG, with no visible benefit, because lossless compression has almost nothing repeatable to exploit in natural photographic noise.

    This situation is common when a photo has passed through an editor or a screenshot tool that defaults to PNG. Converting recovers most of that wasted space immediately.

    When you should not convert

    Screenshots, diagrams, logos, line art, and anything containing text. JPEG cannot represent hard edges cleanly and will surround letters with visible ringing artefacts no matter how high the quality is set. PNG is both smaller and sharper for this kind of content.

    Images with transparency. JPG has no alpha channel, so a transparent background will be filled with solid colour. If the transparency matters, keep the PNG or use WebP, which supports both good compression and an alpha channel.

    Local, unlimited, no account

    PNG decoding is native to your browser. Breezo reads the file with it and re-encodes as JPEG using MozJPEG compiled to WebAssembly, all inside the tab.

    Because nothing is transferred, none of the usual restrictions apply — no 15 MB cap, no two-tasks-per-hour throttle, no watermark, no sign-up. Confirm it in DevTools while converting.

    Frequently asked questions

    Will the file definitely get smaller?

    For photographs, almost always and often dramatically. For screenshots and images with large flat areas or text, the JPG can be larger than the PNG.

    What happens to a transparent background?

    JPG cannot store transparency, so transparent areas are filled with solid colour. Keep the PNG or use WebP if you need the transparency.

    Is the quality loss reversible?

    No. JPEG compression permanently discards data. Converting the result back to PNG only makes the file larger — it cannot restore what was removed.

    Which quality setting should I choose?

    The default 85 is a good balance for photographs. Use 90 or above if the image will be printed or edited further.

    Is my file uploaded?

    No. The conversion runs entirely in your browser. Nothing is transmitted to us at any point.
