Why This Happens

Image data streams inside the PDF are corrupted or use unsupported compression filters. JPEG/DCT and FlateDecode are common culprits when files are improperly edited or converted.

How We Fix It

We identify corrupted image streams, re-encode valid image data with standard filters, and place placeholder markers for unrecoverable images at the correct positions.

😫

The Problem

Your PDF opens but images show as gray boxes, broken icons, or trigger 'Image decoding error' — critical diagrams, photos, or signatures are invisible.

✅

The Solution

Restore or replace corrupted image streams so your PDF displays properly without needing the original source files.

Frequently Asked Questions

Can corrupted images be fully recovered?

If the raw image data is partially intact, we can reconstruct it. Completely overwritten or zeroed-out image data is unrecoverable, but the page layout with placeholders is preserved.

Does this work on scanned PDFs?

Yes. Scanned PDFs store each page as a large embedded image. If the image stream is corrupted, our tool can rebuild it from surrounding data.
