What is AVI?

Common use: Legacy systems, older hardware

Output Format

What is FLAC?

Frequently Asked Questions

Is converting AVI to FLAC free?+
Yes! You can convert AVI 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 AVI to FLAC lose quality?+
It depends on the formats involved. If both AVI 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 AVI to FLAC without uploading my file?+
Absolutely. Filoshi processes everything locally on your computer. Your AVI 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 AVI 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 AVI files to FLAC?+
Yes, the Filoshi desktop app supports batch conversion. You can drop an entire folder of AVI files, select FLAC as the output format, and convert them all at once. Each file gets its own progress bar.
