Frequently Asked Questions

Is converting FLV to FLAC free?+
Yes! You can convert FLV to FLAC for free right in your browser using Filoshi's online converter. No signup or software download needed. For batch conversion of multiple files, the Filoshi desktop app is available for a one-time $14.90 payment.
Does converting FLV to FLAC lose quality?+
It depends on the formats involved. If both FLV and FLAC 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 FLV to FLAC without uploading my file?+
Absolutely. Filoshi processes everything locally on your computer. Your FLV files are never uploaded to any server. Even the free browser converter runs entirely in your browser using WebAssembly, with no server involved.
How long does it take to convert FLV to FLAC?+
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 FLV files to FLAC?+
Yes, the Filoshi desktop app supports batch conversion. You can drop an entire folder of FLV files, select FLAC as the output format, and convert them all at once. Each file gets its own progress bar.
