Why 20 MB?

20 MB is the magic number for Discord's free tier — raised from 10 MB in August 2026 (verified September 2026). It's also a safe size for email attachments, forum uploads, and anywhere else with a ~20–25 MB cap. Instead of picking "Medium quality" and hoping, VidSizer solves the bitrate math for your exact clip and verifies the result is under 20 MB before you download.

FAQ

How do I compress a video to exactly 20 MB?

Select the 20 MB target above and hit Compress. VidSizer measures your clip's duration, computes the precise bitrate, and re-encodes up to 3 times until the output is provably under 20 MB.

Will a 20 MB video look good?

For clips up to a few minutes, yes — typically clean 720p. For very long clips the math gets tight, and the tool will warn you honestly before encoding.

Is my video uploaded anywhere?

No. Everything runs in your browser. No upload, no account, no watermark.
