The ClipSizer app for Android is on its way.

Uncompressed, ready for an editor
WAV is picked, so the sound is saved uncompressed at 16 bits and 44.1 or 48 kHz. Keep the whole video if it runs 10 minutes or less, or choose a part on the waveform. Want a smaller file to share? Save an M4A instead.

Mountain wind, ready to mix
Wind and birdsong from a mountain video, saved as a WAV that audio editors, music apps and transcription tools open as it is. It's big, about 11.5 MB a minute at 48 kHz stereo, so for sharing, an M4A is far lighter.
How it works
Choose your video
Open the video whose sound you want to edit or transcribe.
Keep it all, or choose a part
Up to 10 minutes fits in one WAV. Pick a part for anything longer.
Save your WAV
Download a 16-bit file at 44.1 or 48 kHz, ready for your editor.
Why editors like WAV
A WAV file stores sound as plain samples, with no compression at all. Audio editors, music apps and transcription tools can read it straight away, without decoding anything first, and almost all of them accept it.
That matters when the sound is going to be worked on. Each time a compressed file is edited and saved as MP3 or M4A again, a little more detail is lost. Starting from a WAV means your cuts, levels and effects go through compression just once more, when you export the finished piece.
It's also a simple format to hand over. Whoever mixes, edits or transcribes the sound next won't need to convert it first.
WAV files are big
With no compression, a WAV grows fast: about 11.5 MB for every minute of 48 kHz stereo sound, and about half that for mono. An MP3 of the same minute at 192 kbps is about 1.5 MB.
The whole file is built in your browser's memory before you download it, and a phone tab has far less room than a computer. So each WAV can be up to 10 minutes long, about 115 MB at 48 kHz stereo. If your video runs longer, Whole video is switched off with the reason beside it, and the part starts as the first 10 minutes.
Need all of a long recording? Save it in parts of up to 10 minutes each, or switch to M4A or MP3, which work for up to 60 minutes at a time.
Sample rate and channels
Your WAV keeps the video's sample rate when it's 44.1 kHz or 48 kHz, the two rates most videos use. Anything else is converted to 48 kHz. Every file is 16-bit, which any audio editor can open.
Channels follow the same idea. A mono recording stays mono, which halves the file size. Stereo stays stereo, and a video with more channels is saved as stereo.
The summary line under the settings shows what you'll get before you save, for example "WAV · 48 kHz stereo · 0:42 · About 8.1 MB", so there are no surprises when the download lands.
Questions
Do you upload my video?
No. The WAV is written in your browser's memory and downloaded straight from there. Your video never leaves your device, and no account is needed.
Does it work on iPhone?
Yes, on a recent iPhone in Safari. WAV files are large, so shorter parts save faster on a phone. Older Safari versions can't decode audio in the browser, and the page tells you if yours is one.
Does WAV sound better than the video?
No. A WAV is uncompressed, but it can't bring back what the video's own compression removed. What it gives you is the sound as decoded, with no new compression added, which is what an editor wants.
Why only 10 minutes?
Because WAV files are big. Ten minutes of 48 kHz stereo is about 115 MB, and the file has to fit in your browser's memory, on a phone too. For longer stretches, save several parts or pick M4A or MP3, which go up to 60 minutes.
Which sample rate and bit depth do I get?
16-bit, at 44.1 kHz or 48 kHz. A video at either rate keeps it, and any other rate becomes 48 kHz. Mono stays mono, and two or more channels become stereo.
