Compress MP4 Video to 20MB or Less
Compress MP4 video to 20MB with a visible 19.4MB encoder target, a feasibility check, and an under-limit download.
Designed for a hard 20MB cap. Confirm the current limit shown by the destination before encoding.
Compress video
The video compressor creates a new MP4 download.
Use percentage for an approximate reduction, or enter MB for a strict maximum file size.
20MB rules and nearby targets
Discord’s current 20MB note
Discord’s official attachment FAQ says that, as of August 2026, non-Nitro uploads use a 20MB limit and files are checked before platform compression. It also says some users may be in different upload-limit experiments, so confirm the prompt shown by your account.

Compress video with no server upload
Your selected video is processed on your device, not sent to a compression server.
Compress by percentage or target MB
Choose roughly how small the MP4 should be. The compressor accepts smaller results instead of chasing an exact file size.
Load online, process locally
Keep a connection available to load the page and video engine. Local processing does not guarantee offline access.
Compress MP4 video to 20MB with evidence before encoding
Use compress MP4 video to 20MB when the number matters more than a general quality setting. The tool works backward from duration and reserves room below the external limit.
Compress MP4 video to 20MB with a 19.4MB safety target
The compress MP4 video to 20MB workflow shows both numbers: 20MB is the external limit and 19.4MB is the encoder target. The margin is visible, not hidden.
20MB limit · 19.4MB target
Compress MP4 video to 20MB from the source ratio
After you choose a file, compress MP4 video to 20MB calculates how much the source must shrink. A 100MB source needs about an 81% reduction to reach the safety target.
Source → target ratio
Compress MP4 video to 20MB with a byte-level check
When compress MP4 video to 20MB finishes, the actual MP4 is checked against 19.4MB. A larger result is marked missed and does not receive a success download.

How to compress MP4 video to 20MB
To compress MP4 video to 20MB without guessing, start from the fixed limit, inspect the calculated video bitrate, and change resolution before encoding when the budget is tight.
Choose a source to compress MP4 video to 20MB
Select MP4, MOV, M4V, WebM, or MKV. The compress MP4 video to 20MB tool reads source size, duration, and dimensions in the browser before it plans the output.
Check the ratio to compress MP4 video to 20MB
The compress MP4 video to 20MB panel shows required reduction, total bitrate, audio reserve, video bitrate, and estimated output resolution from the selected file.
Adjust resolution before you compress MP4 video to 20MB
If compress MP4 video to 20MB shows a strained plan, choose 720p or 480p. A smaller frame can look cleaner than underfunded 1080p at the same file size.
Run and verify compress MP4 video to 20MB
Start compress MP4 video to 20MB, keep the tab open, and check the actual output. Download appears only after the result is below the 19.4MB safety target.
When compress MP4 video to 20MB is realistic
Compress MP4 video to 20MB for short clips
Short clips usually leave enough bitrate to compress MP4 video to 20MB at 1080p or 720p. The live panel uses your exact duration instead of a generic promise.
Compress MP4 video to 20MB for longer clips
Long clips divide the same 19.4MB across more seconds. To compress MP4 video to 20MB, you may need 720p, 480p, a shorter edit, or a larger destination limit.
Compress MP4 video to 20MB for Discord carefully
Discord’s official FAQ currently says non-Nitro uploads use 20MB, but it also notes experiments with different limits. Compress MP4 video to 20MB only after checking your account prompt.
Compress MP4 video to 20MB without an exact-size claim
Motion, noise, keyframes, audio, and MP4 overhead change the final bytes. Compress MP4 video to 20MB aims lower and verifies the result instead of promising exactly 20.00MB.
