PROCESSING TRANSPARENCY
Trust center ↗Know what happens before you upload.
A temporary per-request workspace is cleaned when processing ends.
Repair is best effort. A file that cannot be parsed at all, has missing page data, or contains irrecoverably damaged streams may still fail. A structural rewrite can also affect unusual document-level features, so the repaired file should be treated as a new copy rather than a replacement for the only original you have.
Open the repaired result and inspect the first, middle, and last pages. Test text selection, search, and any important links or annotations you rely on. For formal documents, compare the page count and visible content against the original before deleting anything; successful download only proves the rewritten PDF passed Infinity's output checks.

INFINITY INTELLIGENCE
A copilot that understands this tool.
Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.
PRACTICAL CONTEXT
What this tool is good at — and where to be careful.
When this tool makes sense
Best for a PDF that opens inconsistently or appears to contain messy internal structure and you want a clean rewrite before converting or sharing it again. The tool is useful for light structural repair: it rewrites the document, cleans redundant objects, and deflates streams. It is not a forensic recovery system and cannot recreate pages or content that are already missing from a severely corrupted source file.
What the engine actually does
The engine opens the PDF with PyMuPDF and writes a new PDF using garbage cleanup, stream deflation, and structural cleaning. It does not rasterize pages, run OCR, or intentionally redesign the document. That means selectable text and vector content can remain intact when the source is readable, while malformed or redundant internal objects are discarded during the rewrite.
What it does not promise
Repair is best effort. A file that cannot be parsed at all, has missing page data, or contains irrecoverably damaged streams may still fail. A structural rewrite can also affect unusual document-level features, so the repaired file should be treated as a new copy rather than a replacement for the only original you have.
A 20-second quality check
Open the repaired result and inspect the first, middle, and last pages. Test text selection, search, and any important links or annotations you rely on. For formal documents, compare the page count and visible content against the original before deleting anything; successful download only proves the rewritten PDF passed Infinity's output checks.
Frequently asked questions
Can it restore missing pages?
No. It rewrites content the PDF engine can read; it cannot reconstruct data that is no longer present.
Does repair turn pages into images?
No. This workflow rewrites the PDF structure rather than deliberately rasterizing every page.
