Frequently asked questions
Is converting AVI to FLAC free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Will the sound quality drop?
FLAC is lossless, so the soundtrack is carried over as it is.
Does it work on a phone?
Yes. It works on iPhone, iPad and Android, with no app to install.
Is there a file size limit?
There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
