Frequently Asked Questions

Is converting ZIP to 7Z free?+
Converting ZIP to 7Z requires the Filoshi desktop app, which is a one-time $14.90 purchase. This gives you unlimited conversions across 3,332+ format pairs with no subscription or per-file fees.
Does converting ZIP to 7Z lose quality?+
It depends on the formats involved. If both ZIP and 7Z use lossless compression, no quality is lost. If the conversion involves a lossy format, some quality reduction may occur, but Filoshi uses optimized settings to keep quality loss minimal. The conversion runs entirely on your machine, so there are no server-side compression artifacts.
Can I convert ZIP to 7Z without uploading my file?+
Absolutely. Filoshi processes everything locally on your computer. Your ZIP files are never uploaded to any server. The desktop app bundles all conversion engines and works completely offline.
How long does it take to convert ZIP to 7Z?+
Most conversions complete in seconds. Larger files (like high-resolution video) may take a bit longer depending on your computer's hardware. Since Filoshi runs locally, there is no upload or download wait time, which is significantly faster than online converters.
Can I batch convert multiple ZIP files to 7Z?+
Yes, the Filoshi desktop app supports batch conversion. You can drop an entire folder of ZIP files, select 7Z as the output format, and convert them all at once. Each file gets its own progress bar.
