How to use Convert PNG to JPEG
- 1. Upload the PNG image. Drop or browse for the .png file you want to flatten into JPEG. Its current file size shows so you can compare it against the compressed result afterward.
- 2. Set the Quality (%). Adjust Quality (%) to control how much the JPEG encoder compresses the flattened image. Note that any transparent areas in the PNG become solid white in the output.
- 3. Download the JPEG file. The tool flattens transparency to white and re-encodes the image as a compact JPEG at the quality you chose. Download the .jpeg file for the smaller, universally supported result.
When to use Convert PNG to JPEG
Convert PNG to JPEG flattens a PNG image into a compact JPEG, turning any transparency into solid white in the process. Reach for it when file size matters more than an alpha channel you were not actually using anymore.
- Shrinking a large screenshot for an upload. A 4 MB screenshot.png needs to fit a much smaller upload limit; converting it to JPEG produces a far smaller file, especially since screenshots rarely need transparency.
- Preparing a PNG graphic for a photo gallery. A PNG-exported graphic needs to sit alongside JPEG photos in a gallery expecting a consistent format, so it gets converted before upload.
- Removing an unneeded alpha channel before sharing. A design export kept a transparent background that is not needed for the final use case; converting to JPEG flattens it to white and trims the file size.
- Meeting a platform's JPEG-only requirement. A submission portal only accepts JPEG uploads, so a PNG graphic needs converting first, accepting that any transparency becomes solid white in the process.
Examples
Smaller upload
Input
screenshot.png (4 MB)

screenshot.jpg, much smaller
About the Convert PNG to JPEG tool
Convert PNG to JPEG runs as plain JavaScript in your browser tab, with no server behind it. Flatten PNG images into compact JPEGs (transparency becomes white). Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JPG Tools section, 145 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Quality (%) setting, and the result refreshes the moment you change it. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
