HOW IT WORKS

Recovery with evidence, not guesswork.

Not every damaged archive can be fully restored. PixelOkay shows what it actually recovered.

⌕

01 / Inspect ZIP records

Locate ZIP headers, map file boundaries, and find entries even when the central directory is missing.

✓

02 / Validate recovered bytes

Read supported file data and compare its size and CRC-32 checksum. Report ambiguous or damaged content separately.

▣

03 / Rebuild a clean archive

Export readable files with new ZIP metadata and safe filenames, without overwriting the original archive.

KNOW BEFORE YOU REPAIR

Frequently asked questions

Can a ZIP be repaired if its central directory is missing?

Often, yes. ZIP archives typically also contain local file headers. This tool scans for those headers and can salvage entries whose compressed data is still readable, including many archives with missing end records.

Does this tool fix corrupted file contents?

It cannot reconstruct missing bytes or magically repair damaged compressed streams. It validates files it can decode and labels CRC mismatches, truncated data, and incomplete recoveries. Partial results require your explicit approval.

Which ZIP compression formats are supported?

Stored (method 0) and DEFLATE (method 8) are supported when the browser provides raw DEFLATE decoding. Encrypted files, multi-volume archives, and unsupported compression methods cannot be recovered. Very large ZIP64 archives may exceed browser limits.

Are there file size or recovery limits?

Each recovered file is limited to 256 MiB, and the total retained recovered content is limited to 768 MiB per session. ZIP rebuild uses standard ZIP32 and uncompressed files; very large or heavily compressed archives may not be supported. Mobile devices may have lower practical memory limits.

Is the uploaded archive private?

Yes. The JavaScript processing takes place locally. There is no upload, remote conversion, analytics dependency, or account requirement in this tool. Downloaded recovered files remain on your device.

What is the difference between verified and partial recovery?

Verified means the output decoded successfully and matches the expected original size and CRC-32 checksum. Partial indicates that a checksum, size, content boundary, or decompression check failed or could not be completed.

FILE INSPECTION DETAILS

Entry details

Status is based on recovered data and available archive metadata. Unverified entries have not passed an integrity check.

Using ZIP Repair & Recovery

Inspect ZIP directory records or scan local headers when directory metadata is damaged, review recovery evidence, then choose entries for rebuild or saving.

Workflow

  1. Open a local ZIP and inspect directory diagnostics
  2. run the bounded local-header scan if needed and review evidence
  3. select verified or explicitly partial entries, then save recovered files or rebuilt ZIP32 output.

Example

For an archive with a damaged central directory, scan local headers, compare names and CRC/size evidence, then export only reviewed entries and mark partial output clearly.

Limits and data handling

Recovery cannot recreate missing or corrupted compressed bytes. Encrypted entries, unsupported compression and split archives are unsupported. Raw DEFLATE depends on native browser support. Partial recovery needs explicit selection and remains distinct from verified output. Rebuilt archives use stored classic ZIP32 entries. CRC and size checks are not authenticity or malware checks.

FAQs

Can recovery restore data whose compressed bytes are missing?

No. It can inspect remaining bytes but cannot manufacture missing content.

Does a matching CRC prove an archive is safe?

No. CRC and size checks detect some corruption but do not establish authenticity or malware safety.
