Frequently asked questions
Is PixelTools' audio converter free?
+
Yes, completely free with no limits. Convert as many files as you want, as often as you want. No subscription, no trial, no account required.
What audio and video formats can I convert between?
+
PixelTools converts between WAV, MP3, M4A, and OGG audio, extracts audio from MP4, MOV, and WebM video, and also converts FLAC files to MP3. Each conversion pair has its own dedicated page for the clearest results.
Are my files uploaded to a server?
+
No. PixelTools converts audio and video entirely in your browser using a WebAssembly build of ffmpeg. Your files never leave your device — there is no server upload, no cloud processing, and no data stored anywhere.
Can I extract audio from a video file?
+
Yes. PixelTools extracts the audio track from MP4, MOV, and WebM video files and saves it as MP3 or WAV, without re-encoding the video.
Does converting audio reduce quality?
+
It depends on the formats involved. Converting to a lossless format like WAV preserves full detail when the source is also lossless, though it can't restore quality a lossy source already discarded. Converting to a lossy format like MP3 or OGG uses a high-quality encoder setting by default, so the difference is minimal for typical listening.
How is this different from an online audio converter that requires upload?
+
Most online converters upload your file to a server for processing and impose file size or daily limits on free accounts. PixelTools converts everything locally in your browser with no upload, no limits, and no account required.
What is the maximum file size I can convert?
+
PixelTools can handle files up to 2GB. Very large files may take a few moments to process since conversion runs on your device's CPU rather than a server.
