Give it a target size and it hits it. Two-pass encoding works out the right bitrate for your footage, then the result is measured and corrected so the file lands under your limit instead of near it. No account, no watermark and nothing to install.

Most online compressors guess a bitrate once and hand you whatever comes out. This one measures and corrects, which is the difference between "about 25 MB" and "under 25 MB".
The first pass analyses your footage and the second spends the bitrate where the picture needs it. Still shots get less, fast motion gets more.
Two passes alone often land several percent under target. The output is measured and the encode is repeated once with a corrected bitrate, so you get close to your limit without ever crossing it.
Ask for 5 MB from a 20-minute video and it says no, and tells you the smallest size that is actually achievable — instead of handing back an unwatchable file.
If you do not care about an exact size, choose High, Medium or Low. Each shows an estimated output size before you start.
Keep the original resolution or drop to 1080p, 720p or 480p. Lowering the resolution is often the cheapest way to reach a small target while keeping the picture clean.
H.264 video with AAC audio and fast-start enabled, so the file plays everywhere and starts immediately when streamed.
Drop in an MP4, MOV or WebM. The file is inspected with FFprobe, so anything that is not really a video is rejected before any work starts.
Type a target in MB, or use a preset: 8, 16, 25, 50 or 100 MB. The tool shows the smallest size your clip can reach.
Keep the original or scale down. The aspect ratio is preserved automatically and the video is never scaled up.
Watch the progress bar, preview the result in the page and download it. Your upload is deleted as soon as the encode finishes.
The default recording format on almost every phone and camera.
QuickTime files from iPhones, iPads and Mac screen recordings.
Common output from browser recorders and open-source capture tools.
Limits. Up to 500 MB and 30 minutes per file, and three videos per hour per visitor. At most two encodes run at once and anything else waits briefly in a queue. Video encoding is expensive, and these limits are what let the tool stay free.
Most messaging apps and mail servers stop at 25 MB. Set that as your target and the file will fit on the first try.
Issue trackers cap uploads at 10 MB or so. A short screen recording compresses well below that at 720p.
Learning platforms often enforce a fixed limit and reject anything above it without explaining why.
Screen recordings are enormous for what they contain. Compressing them before archiving costs nothing in visible quality.
This tool changes file size, and that is all. It does not trim, crop, rotate, merge, add subtitles or change the audio. If you need to cut a section out first, use the video cutter and compress the result afterwards.
Compression is lossy by definition. Ask for a very small target from a long or highly detailed video and the picture will soften — that is arithmetic, not a bug. When a target would push quality below anything usable, the tool refuses it and tells you the smallest size that still works.
Yes. The encode is measured after it runs and repeated once with a corrected bitrate if it landed outside the band. Overshooting the target is treated as a failure, so the tool always errs on the small side.
It depends entirely on how far you are compressing. Halving a file is usually invisible. Cutting a 200 MB video to 8 MB is not, and dropping the resolution will look better than keeping it at that size.
If your target is small, yes. A clean 720p file beats a blocky 1080p one at the same size. For screen recordings with text, keep the resolution and accept a larger target instead.
No. The output is a plain MP4 with nothing added, and the file name contains no tracking of any kind.
The upload is deleted immediately after the encode finishes and the compressed result is removed an hour later. No account, nothing stored.
Encoding video is by far the most demanding thing on the server. Three videos per hour keeps the tool free and responsive for everyone rather than fast for one person and unavailable for the rest.
Pick a target size, let it encode and download a file that fits.
