PDF Repair

Jaribu kurekebisha PDF zilizoharibika kwa qpdf ya ndani, normalize faili dhaifu, na tumia salvage ya kurasa kama muundo hauwezi kurejeshwa.

Ripoti ya marekebisho
Jinsi kurekebisha PDF kunavyofanya kazi
Zana hii hujaribu marekebisho kwa hatua, ikianza na muundo na kumalizia salvage ya kuona kama faili bado inaweza kusomeka.
  • Checks headers, xref, trailer, EOF marker, encryption, and object hints
  • Uses local qpdf/WASM to rebuild damaged structure
  • Normalizes valid PDFs with compatibility-friendly output
  • Can rasterize recoverable pages into a fresh PDF when structure repair fails
Hufanya kazi vizuri kwa: headers zilizoharibika, cross-reference tables zilizovunjika, downloads zisizokamilika, bytes za ziada kabla ya PDF header, na PDF zinazofunguka kwenye browsers lakini kushindwa kwenye readers kali.

Faili yako haitoki kwenye kifaa chako. Uchakataji hufanyika kwenye kivinjari kwa JavaScript. Hakuna data inayopakiwa kwenye seva.

The Kurekebisha PDF tool attempts to fix damaged files that fail to open in strict readers. It inspects the file header, EOF marker, xref and trailer hints, encryption markers, and page recovery signals, then tries a local qpdf rebuild, a pdf-lib compatibility save, and an optional raster-page salvage. Your PDFs are processed entirely in your browser and can be downloaded individually, bundled as a ZIP, or documented with a JSON or CSV repair report.

Maswali ya mara kwa mara

Inaweza kusaidia PDF zenye bytes za ziada kabla ya header, cross-reference tables zilizovunjika, trailers zisizokamilika, EOF markers zilizokosekana na object streams dhaifu. Hufanya kazi vizuri zaidi kama maudhui ya ukurasa bado yapo ndani ya faili.
No. The entire repair process runs locally in your browser using JavaScript. Your file never leaves your device and no data is sent to any server. This ensures complete privacy for sensitive documents.
Raster salvage renders each readable page as an image and places those images into a new PDF. It can rescue a document that still displays, but the resulting file is image-based and may lose selectable text, links, forms, and tags.
Repair can fail when the file is not a PDF, the page data is missing, the file is heavily truncated, or an encrypted document needs a password that was not provided. Try re-downloading the original file if possible.
Structural rebuilds should preserve recoverable content closely. Raster salvage prioritizes readability over editability, so the page appearance is preserved as images while selectable text and form behavior may not survive.
