Convert PNG to JPEG — free, private, in your browser
Decoded with OxiPNG, encoded with MozJPEG — entirely on your device. No upload, no queue, no watermark.
Why convert PNG to JPEG?
A photo saved as PNG is 5–10× bigger than it needs to be. Converting PNG to JPEG collapses the size (transparency becomes a background color, which you can choose). Everything happens in your browser via MozJPEG.
How to convert PNG to JPEG
- 1Drop your PNG files onto the tool above (or click to browse, or paste from the clipboard). Batches are fine.
- 2JPEG is pre-selected as the output. Adjust the quality slider — 80 is visually lossless for most photos. Optionally cap the maximum dimension to also downscale.
- 3Each file converts in your browser and shows its new size. Download files individually or grab everything as a ZIP.

Frequently asked questions
Is it safe to convert PNG to JPEG online?+
With EditItAll, your files are never uploaded: decoding and encoding run inside your browser using WebAssembly (Squoosh-grade codecs (MozJPEG, libwebp, libavif, libjxl, OxiPNG) to decode, Squoosh-grade codecs (MozJPEG, libwebp, libavif, libjxl, OxiPNG) to encode). The images stay on your device from start to finish, and the whole thing works offline once the page has loaded.
Will converting PNG to JPEG lose quality?+
JPEG is a lossy format, so re-encoding discards some information — at quality 80+ the difference is invisible for photos. Use the quality slider to choose the trade-off; nothing else in the pipeline degrades the image.
What happens to transparency when converting to JPEG?+
JPEG has no alpha channel, so transparent areas are flattened onto a background color (white by default — you can pick another in the options).
Is there a file size or count limit?+
No hard limits and no accounts — processing uses your own device's memory and CPU, so very large images are only constrained by your browser (multi-hundred-megapixel images may fail on low-memory devices). Batch as many files as you like; they are processed in sequence.
Can I convert JPEG back to PNG?+
Yes — use the JPEG to PNG converter, or just change the output format dropdown after dropping files.
