Best for these corruption symptoms

  • •PNG screenshots, exported design assets, and graphics that suddenly stopped opening
  • •Files affected by broken IHDR or other chunk-level corruption
  • •Images that display missing transparency, broken colors, or truncated content

Typical signs of this problem

  • •Browsers and editors say the PNG is invalid, corrupted, or uses an unsupported structure
  • •The image opens with missing areas, black blocks, or unexpected transparency artifacts
  • •A file validator reports damaged or out-of-order PNG chunks

Common root causes

  • •The PNG file was interrupted while exporting from a browser, editor, or screenshot tool
  • •Compression or sync tools altered the file and damaged chunk boundaries

Why local browser repair matters

PNG corruption is often structural, not visual, which makes file-level repair the right first step.

PhotoRepair understands common PNG chunk issues and is designed to rebuild valid layout when possible.

Because the process stays local, you can repair internal product assets and client graphics without leaving the browser.

Ready to test the damaged file?

Frequently asked questions

Can PhotoRepair fix PNG files with chunk errors?

Yes. PNG files commonly fail because chunk structure is invalid or incomplete, and PhotoRepair is built to inspect and recover that layout where possible.

Will the repaired PNG keep transparency?

If the original alpha and image data are still available in the damaged file, PhotoRepair will try to preserve them during repair.

Does this help with screenshots and design exports?

Yes. Broken screenshots, UI assets, and exported graphics are strong candidates, especially when the file became corrupted after sync or save interruption.
