ToolPemulihan sepenuhnya lokal
PDF rusak diperiksa di browser. Dokumen, diagnosis, dan hasil tidak dikirim ke layanan recovery eksternal atau disimpan di server.
A SECOND CHANCE FOR YOUR DOCUMENT.
Repair PDF.
Analyze damaged PDF files and recover readable content whenever possible.
Private Recovery — Your file stays on your device.Free · No file-size quota
Diagnosis sebelum klaim
QPDF memeriksa dan menulis ulang struktur yang dapat dipulihkan. Hasil diperiksa kembali, lalu dibedakan antara valid, diperbaiki, pulih sebagian, dan gagal.
Selamatkan yang masih terbaca
Deep Repair dan Page Recovery menyediakan jalur pemulihan terbatas yang bisa ditinjau. Dokumen asli tetap utuh; halaman hilang tidak dibuat-buat.
Cara menggunakan Repair PDF
Periksa PDF yang gagal dibuka atau memiliki struktur bermasalah. QPDF mencoba pemulihan referensi dan penulisan struktur baru; Deep Repair dapat mencoba salvage halaman yang masih dapat diparse. Hasil dilaporkan sebagai sudah valid, diperbaiki, pulih sebagian, atau gagal sesuai pemeriksaan aktual.
- Select your damaged PDF. File tetap di perangkat Anda. Pemeriksaan header, cross-reference, trailer, page tree, dan enkripsi dimulai setelah mesin siap.
- Review diagnostics and available previews. Kegagalan preview tidak menghentikan analisis. Quick Repair memakai QPDF dan rekonstruksi objek terbatasi; Deep Repair dapat mencoba pemulihan objek halaman dengan keterbatasan yang perlu dikonfirmasi.
- Choose pages and recovery settings. Partial output dan pembuatan ulang sebagai gambar hanya dijalankan ketika dipilih. Gambar pengganti dibuat dari halaman yang benar-benar dapat dirender, tanpa isi buatan.
- Analyze & Repair PDF. Candidate ditulis ulang, diperiksa secara struktural, dan dirender oleh parser independen sebelum unduhan tersedia. Periksa hasil dan unduh laporan diagnosis.
Pertanyaan tentang Repair PDF
Can a corrupted PDF be repaired?
Sometimes. Cross-reference pointers, recoverable trailers, and accessible object references may be reconstructed. QPDF is used locally for real structural recovery. Missing file bytes, unreadable streams, or destroyed resources may prevent complete recovery; no tool can recreate arbitrary missing content.
Why does a PDF fail to open?
Possible causes include interrupted transfers, incomplete saves, damaged cross-reference information, invalid object references, or missing content. Diagnostics report what can actually be inspected; a specific cause is not asserted without evidence.
What is the difference between Quick Repair and Deep Repair?
Quick Repair combines QPDF with a bounded independent parsed-object rewrite for supported structural damage. Deep first tries that path, then may salvage parsed orphan page objects when a catalog/page tree cannot be used. Salvage cannot prove original page order or completeness and may omit document-level features. Deep is not guaranteed to recover more.
Can I recover only readable pages?
Yes. Page Recovery or Recover Readable Pages Only explicitly permits partial output. Accessible pages can be previewed and selected. Pages that fail independent rendering are reported. No blank replacement pages or fabricated content are added.
Can all damaged PDF files be recovered?
No. If a validated nonempty output cannot be produced, the result is Unable to Repair and no successful-repair claim is made. Keep the original, download diagnostics, try a different recovery mode, or obtain another source copy.
Does repair reduce quality or remove searchable text?
QPDF structure rewriting preserves existing page resources without image recompression. Recoverability of annotations, forms, bookmarks, metadata, and resources depends on surviving structures. Explicit image-only rebuilding rasterizes pages and loses selectable text, vectors, and interactive features; this warning is shown before processing. PDF OCR can add a new text layer afterwards.
What if the PDF is already valid, protected, or signed?
A source that passes structural checks is labelled already valid, with a normalized copy available if requested. Protected PDFs require an unlocked copy; no bypass is attempted. Rewriting can invalidate digital signatures, and detected signatures require explicit confirmation.
Are damaged documents uploaded?
No. Diagnostics, QPDF WebAssembly recovery, optional page salvage, rendering, validation, reports, and downloads are local. No remote repair API or hidden server fallback is used. Loaded dependencies can be reused in the open page; initial modules still need to be available. There is no application file-size quota, but device memory, object/pixel budgets, and timeouts apply.
