Frequently Asked Questions
- Which archive formats are supported?
- FileCrank can create ZIP archives and extract .zip files. The ZIP format is the most universally compatible β it opens natively on Windows, macOS, iOS, and Android without any extra software.
- Can I compress multiple files at once?
- Yes. The Compress Files tool accepts multiple files and packages them into a single ZIP archive. You can also select entire folders in browsers that support directory upload (Chrome and Edge).
- Is there a file size limit?
- FileCrank supports individual files up to 100 MB and total archives up to 500 MB.
- Are the archive tools free?
- Yes, all archive tools are completely free. No subscription, no signup, and no hidden fees.
- Is my data kept private?
- Uploaded files are processed securely and automatically deleted within 1 hour. We never read or retain your data.
- What is the difference between ZIP, 7Z, and TAR.GZ?
- ZIP is the universal standard supported by every operating system without extra software. 7Z (7-Zip) achieves better compression ratios but requires a 7-Zip application to open. TAR.GZ is the standard format on Linux and macOS servers β it bundles files first (TAR) then compresses the bundle (GZ). For sharing files with Windows users, ZIP is always the safest choice.
- How do I open a ZIP file on iPhone or Android?
- On iOS 13+ you can tap a ZIP attachment in Mail or Files to extract it natively. On Android 10+ the Files app can extract ZIPs directly. For older devices or more complex archives, the FileCrank Extract ZIP tool works in any mobile browser β no app download required.
- What does "repack" a ZIP archive mean?
- Repacking re-compresses an existing ZIP using the best available compression settings. Many ZIP files are created with speed-optimised (fast but larger) compression. Repacking with higher compression can reduce the file size by 10-40% without changing any of the files inside.
