PRIVACY

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Creation and extraction use browser memory, so very large batches can exceed available resources.
Absolute paths, “..” segments and entries larger than 1 GB uncompressed are blocked from extraction.
CRC-32 verification reads the full archive contents and can be expensive for large ZIP files.
Password-protected ZIP files cannot be decrypted by the current JSZip engine.
