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 analytics, ads, or AI scripts are enabled in this version.
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. Very large archives, nested extraction, 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.
If its filenames are encrypted, enter the password and click Open archive.
Select the files to extract, then download the results.
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.
Why does my 7z file ask for a password before showing files?
7z archives can encrypt their file listing as well as their contents. The original password is needed to read that listing; this tool cannot recover it.
Will folders be preserved?
The file list shows nested paths. Each downloaded file uses its basename, so this tool does not recreate the folder tree on your device.
How large can the archive be?
Input is limited to 128 MiB, with up to 500 file entries and 256 MiB of expanded data. Split archives are unsupported and links are omitted.
