A quick guide
Choosing the right Video & Audio tools
Most online video converters upload your file to a server, cap free files at a few hundred megabytes or 1 GB, and ration conversions with daily credits. These tools run on your device instead, using your browser's built-in, hardware-accelerated media engine.
Compatible MOV videos are repackaged as MP4 in seconds without re-encoding, audio is extracted to MP3 at the bitrate you choose, and GIFs are built frame by frame with dithering. Unusual formats fall back to an FFmpeg engine that also runs locally.
Digital ToolPad brings together 16 free Video & Audio tools in one collection. Open a tool, add your input, and review the result on your device. All tool processing happens in your browser, without uploading your data to our servers for processing.
Are my videos uploaded when I use these converters?
No. Files are read and converted by your browser on your device. Nothing is sent to a conversion server, so private recordings, client footage and family videos stay with you.
Is there a file size limit?
We don't set one. The fast engine reads files in small pieces, so multi-gigabyte videos work on most computers. The practical limit is your device's memory; in Chrome and Edge a single large MP4 can be saved straight to disk while it converts.
Which formats are supported?
Input: MOV, MP4, M4V, WebM, MKV, M4A, WAV, FLAC, OGG and more. Output: MP4 (H.264), MP3 (128–320 kbps) and animated GIF. Formats your browser can't decode, such as ProRes or AVI, automatically use a local FFmpeg engine.
