Privacy, compatibility & limits
File contents and passwords are processed in a dedicated worker in your browser. They are not uploaded, logged, or saved by this app. Downloads remain available until you change the operation or close the page. Your browser manages downloaded files. The web server may log ordinary page requests. No ads or AI scripts are enabled in this version; cookieless, self-hosted analytics counts page views only and never receives file contents, filenames or passwords.
Input limit: 128 MiB total and 500 files. ZIP extraction is limited to 500 entries and 256 MiB of expanded data. Operations stop after two minutes, or when you cancel. 7z and Zstandard creation have a 64 MiB input limit. Zstandard extraction is limited to 128 MiB with single frames and no external dictionaries. Compressed tar files (.tar.gz, .tgz, .tar.xz, .tar.bz2) are unpacked in two steps; the inner tar counts toward the 256 MiB limit. Archives whose compression dictionary exceeds 128 MiB are refused to protect browser memory. Converting to ZIP keeps folder paths but not empty folders, links, or the original password. Very large archives, nested archives inside archives, and split archives are outside this version’s scope. RAR is extraction-only. Modern browser support is required.
Password protection uses AES-256 via zip.js for ZIP and 7-Zip WebAssembly for 7z. ZIP filenames and file sizes are visible; 7z can encrypt its file listing too. Password-protected ZIP compatibility varies by archive app; there is no password recovery. An external security review is still needed before making stronger security assurances.
For an archive with encrypted file names, enter the password and click Open archive to see its contents.
Choose which files to include, click Convert to ZIP, and download the new archive.
Before you start
File processing happens on your device. File contents and passwords are not uploaded to FileLance. Your original files stay unchanged; save the results before leaving the page. Large files can use significant browser memory, especially on phones.
Limits
Input up to 128 MiB; up to 500 files and 256 MiB once extracted.
Archives that need a compression dictionary above 128 MiB are refused to protect browser memory.
Empty folders and links are not copied into the ZIP, and the result has no password.
Who needs a ZIP instead of a 7z?
Anyone without 7-Zip or a similar app. Windows, macOS, and most phones open ZIP files natively, so a ZIP is easier to send.
Can I convert a 7z with hidden file names?
Yes, if you know the password. Enter it and open the archive first; the list of files appears once the password is accepted.
Does this change my original 7z?
No. Your 7z stays as it was. The ZIP is a new file created in your browser for you to download.
