FAQ
Are my audio files safe on PDFDocks?
+
Yes. All audio conversions happen directly in your browser, without uploading your files to any server. The first time you use a tool, your browser downloads the necessary conversion engine (a component of a few megabytes), and from then on the entire process stays on your device.
What audio formats are supported?
+
For now: MP3, WAV, OGG, and FLAC, in both directions between them. We'll be expanding the available formats over time.
Why does the first conversion take longer than the following ones?
+
The first time you use an audio tool, your browser needs to download the conversion engine. Once downloaded, your browser caches it and subsequent conversions are faster.
Is there a file size limit?
+
We haven't set any artificial limits. The only real limit is your device's memory and processing power — very large or long files may take longer to process.
