Video limits by platform

Every limit, with its source

The nine platforms use the limits Yaybird posts with: the stricter of each platform’s own docs and our publisher’s, so a file made here goes through either way. Checked October 2026.

Writing the caption too? The free post preview shows it on all 9 platforms, with each limit.

Questions

Video compressor questions

How do I compress a video for Instagram?

Drop it here and pick Instagram. You get an MP4 under 300 MB, at most 1080×1920 (a 9:16 Reel stays 1080×1920), with H.264 video and AAC sound, which is what Instagram asks for. Starting from a file in that shape also means Instagram squeezes it less, so it looks sharper.

What is the Discord file size limit?

20 MB for free accounts since August 2026 (it was 10 MB before). Pick Discord and the file comes out under it. Nitro accounts can send more.

How do I send a long video on WhatsApp or by email?

Pick WhatsApp for a file under 16 MB, or Email for one under 18 MB: Gmail’s limit is 25 MB, but an attachment grows by about a third when it is sent. A long video gets a smaller picture to fit, so for a sharp result, trim it first.

Is my video uploaded anywhere?

No. Your browser does all the work with its own video encoder (WebCodecs). The video never leaves your device, nothing is stored, and there is no account.

The page uses Mediabunny, an open-source video library under the Mozilla Public License 2.0; its source is at github.com/Vanilagy/mediabunny.

What does “All 9 apps” make?

One file that every platform takes: under 50 MB, 4 s to 1 min long, at most 1920×1080 and 30 frames a second. Bluesky and X set most of those limits. For a longer video, pick each place on its own.

Does it work on an iPhone or Android phone?

Yes, in Safari 16.4 or newer and in Chrome. It uses the phone’s own video chip, so a short clip is quick; a long one takes longer and warms the phone. Very long or very large videos (over about 1 GB) can run out of memory on a phone; a computer is safer for those.

Is there a watermark or a limit?

No watermark, no sign-up and no limit on how many videos you make. It is free because it costs us nothing to run: your device does the work.
