Frequently asked questions
Clear answers before you convert
Privacy, quality, batch processing, file size and compatibility explained clearly.
Are my files uploaded to a server?+
No. Media-file conversion happens inside your browser. Convertere Fabrica does not need to receive the file in order to convert it.
Can I convert several files at once?+
Yes. You can add multiple compatible files, process them in a queue and download results individually or together in a ZIP.
Why can the first conversion take longer?+
The browser prepares the audio engine the first time. Later conversions in the same session usually start faster.
Does converting improve audio quality?+
No. Conversion changes format, compatibility or size, but it cannot recover audio information that was already lost in the original file.
Does it work on mobile?+
Yes, in modern browsers. Performance depends on available memory, file size and device capabilities.
Which formats does Convertere Fabrica support?+
We currently work with common formats such as MP3, WAV, FLAC, AAC, M4A, OGG, OPUS and AIFF, plus several video sources with audio tracks.
