How to use Fix a Broken JPEG
- 1. Upload the broken JPEG. Drop the corrupted or truncated JPEG into the input pane, whether it is missing its end marker, has garbage bytes before the header, or was cut off mid-download.
- 2. Let the tool repair the structure. The repair pass locates the real start-of-image marker, discards leading junk, and appends a proper end-of-image marker if one is missing, without needing any settings from you.
- 3. Download the fixed JPEG. Click process and download the repaired file. It should now open cleanly in image viewers that previously rejected or partially rendered the broken original.
When to use Fix a Broken JPEG
Fix a Broken JPEG attempts to repair a corrupted or truncated JPEG file by finding the correct start-of-image marker and restoring a proper end-of-image marker. Use it when a photo viewer refuses to open a file, or only renders part of an image before erroring out.
- Recovering an interrupted download. A photo download got cut off partway through, leaving a file that starts fine but has no end-of-image marker, and most viewers refuse to open it as a result.
- Cleaning up a file with junk prepended. A JPEG was copied through a tool that prepended extra bytes before the real FFD8 header, and the file needs that leading garbage stripped before it opens correctly.
- Salvaging a photo from a failed transfer. A photo transferred over a flaky connection or from a damaged storage card opens as a gray box or errors out, and running it through the repair tool restores a valid structure.

About the Fix a Broken JPEG tool
Fix a Broken JPEG runs as plain JavaScript in your browser tab, with no server behind it. Attempt to repair a corrupted or truncated JPEG file. 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.
There is nothing to configure. Provide the input and the result appears on its own. 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.
