About xDelta Patcher

A straightforward place to apply an xDelta patch, with your original file kept intact and your data processed on your device.

Made for the task

Bring your files.
Make the changes.

xDelta Patcher combines an .xdelta patch with its matching original to create a separate output. Choose files directly or select entries inside a ZIP. The original selector accepts any filename extension.

Processing happens in your browser using xdelta3. Your original, patch, ZIP and result are not uploaded. General website usage is measured separately, as described in the Privacy Policy.

What happens to your files

A separate result, every time.

The patch decides what’s needed

The creator specifies the required original and the output format. This website does not supply game files or patches, create patches or convert other patch formats into xdelta. Use files you are permitted to use and keep your original.

If you are applying a patch for the first time, the illustrated guide shows the controls, ZIP choices and download steps.

Know the practical limits

Patched output and each extracted ZIP entry are capped at 512 MiB. Browser memory can impose a lower limit. Support for a filename does not guarantee a patch will match it.

A successful decode does not establish that a game will run. Check any expected output hash and follow the creator’s instructions. If validation fails, start with the checksum troubleshooting steps.
