Repair PDF Online

Email scanners, interrupted downloads, and USB copy glitches produce PDFs that Acrobat opens with warnings or refuses entirely. Repair rewrites the cross-reference table and stream objects so standard readers load the document again.

Siliph Repair PDF analyzes uploads in the browser-backed pipeline with encrypted handling, salvaging readable pages when damage is partial. Severely truncated files may lose trailing pages—recovery is best-effort, not guaranteed magic.

Run repair before Merge PDF or Split PDF when one bad attachment blocks an entire workflow. Re-exporting from the original application is ideal when available; repair helps when only the broken PDF remains.

Auto-deletion within two hours on the free tier limits exposure of recovered financial data, and repair requires no signup. After success, Compress PDF if the rebuilt file grew during restructuring.

If repair fails, request a fresh export from the sender or restore from backup tapes before assuming content is lost forever.

Siliph scan tools run OCR, deskew, and grayscale cleanup in the browser, turning camera captures into searchable PDFs without Acrobat. Scans are encrypted end to end, removed after your session, and available instantly with no signup.
