How to compress a video to 10 MB (and actually hit it)
Ten megabytes is not a quality preference — it is a wall. Discord’s free tier, ticket systems and forum uploaders refuse a 10.4 MB file as flatly as a 400 MB one. This guide covers where that wall stands, the arithmetic of fitting under it, and how Target Size mode does the fitting for you.
Where the 10 MB wall appears
The best-known 10 MB wall is Discord’s free tier: attach anything larger and the upload is refused outright, with no partial credit for being close. The limit sits on the finished file, not the video inside it, so the only thing that counts is the number the file actually lands on.
The same ceiling turns up in quieter places. Support-ticket systems routinely cap attachments at 10 MB, forum software ships with defaults in the same range, and plenty of corporate mail gateways still bounce anything in double digits. If you have ever sent a screen recording to a help desk, you have already met this wall.
A quality preset is the wrong tool for a wall. Presets aim at how the video looks and let the size land where it may; a hard ceiling turns the problem around — the size is fixed and the look has to be negotiated inside it. That reversal is exactly what the Video Compressor’s Target Size mode exists for.
The arithmetic, and what the engine does with it
The arithmetic is short. Ten megabytes is about 80 megabits, and a video spends bits per second, so divide by duration: a one-minute clip gets roughly 1.3 Mbps, which is enough for genuinely good 720p. A five-minute clip gets about 260 kbps for picture and sound together, which honestly fits 360–480p and not more.
The division is the easy part; the judgement calls after it are not. The right resolution depends on the bitrate, the frame rate, how much of the budget the audio should keep, and what the source codec already looks like. Target Size reads the file first — duration, resolution, frame rate, codec — and derives the bitrate, resolution and audio settings from it, so the arithmetic and the judgement both happen before encoding starts.
The encode itself runs in two passes: the first surveys where the difficult seconds are, the second spends the budget accordingly. Results land within about 3% of the target and never intentionally over it. And an impossible ask does not fail — you still get the closest file the maths allows, along with concrete suggestions: raise the target, lower the resolution, or drop the audio track.
Setting the target — and knowing when 10 MB is too small
On the tool page, pick the mode card marked with a star: Target Size. 10 MB is one of the quick chips, alongside 5, 8, 16, 20, 25, 50 and 100 MB, and a slider or number input accepts any custom value from 5 to 500 MB. Everything is free and runs without a signup, inputs up to 2 GB are accepted, and files delete themselves after a few hours.
The advanced options exist for the cases the automatics cannot know about. Removing audio hands its whole bitrate share to the picture — worth it for silent screen recordings. Keep resolution and keep FPS pin what the engine would otherwise trade away, and preserve metadata keeps dates and location intact. Codec can stay on Auto or be forced to H.264, H.265 or AV1: the newer codecs buy noticeably more quality per bit at the cost of encode time, and maximum compression versus fast encode makes the same trade for the encoder’s effort.
Sometimes 10 MB is simply the wrong number. A twenty-minute 1080p recording squeezed to 10 MB works out near 65 kbps — below what any codec can make watchable. At that point the honest moves are to trim the clip, raise the target where the platform allows it, or share a link instead of a file. The tool will still hand you the closest possible result and say plainly which of those moves would help most.
Step by step
- 01
Open the Video Compressor
Go to the free Video Compressor — no signup, everything in your browser — and drop in your video. Files up to 2 GB are accepted.
- 02
Pick the Target Size card
Select the mode card marked with a star: Target Size. It switches the tool from quality presets to a hard size budget.
- 03
Set the target to 10 MB
Tap the 10 MB quick chip — it sits alongside 5, 8, 16, 20, 25, 50 and 100 MB — or use the slider or number input for any value between 5 and 500 MB.
- 04
Adjust the advanced options if needed
Remove audio on silent recordings, pin resolution or FPS, preserve metadata, or pick a codec — Auto, H.264, H.265 or AV1. The defaults are right for most files.
- 05
Compress and download
Start the job. Two-pass encoding lands the file within about 3% of 10 MB, never intentionally over. Download the result — everything is deleted automatically after a few hours.
Frequently asked questions
Will a video squeezed to 10 MB still look good?
It depends almost entirely on duration. Around one minute, 10 MB funds genuinely good 720p. Around five minutes the budget is roughly 260 kbps, which the engine spends on a clean 360–480p picture rather than a blocky 1080p one. It always picks the best-looking combination the budget allows.
How long does compressing to 10 MB take?
A little longer than a quality preset, because the file is read twice — that second pass is what lands the result within about 3% of the target instead of somewhere near it. Time scales with clip length, the fast encode option trades a sliver of efficiency for speed, and H.265 and AV1 take longer than H.264.
Is it really free?
Completely. There is no signup, no watermark and no paid tier holding back the good settings — Target Size and every advanced option are open to everyone. Inputs up to 2 GB are accepted, and both your upload and the result are deleted automatically after a few hours.
Does it work on a phone?
Yes. The tool is fully responsive and runs in the mobile browser you already have — nothing to install. Pick the clip from your camera roll, tap the 10 MB chip and download the result exactly as you would on a desktop.
