Compress video online
Get a video under an upload limit. Two levers do almost all the work — resolution and quality — and you can see the effect of both before you commit to the export.
Your video never leaves your device. There is no upload, no queue and no server copy. Free, with no sign-up, no watermark and no export limit.
Cosa puoi fare
Resolution and quality together
Halving the resolution removes three quarters of the pixels. That is a bigger lever than quality, and it is usually the one to reach for first.
No upload cap
Because nothing is uploaded, a 300 MB source is no harder to handle than a 3 MB one. Compression services usually cap what you can send them.
See it before you export
Change the resolution and watch the preview. What you see is what the file will contain.
Choose the container
MP4 for compatibility, WebM when you want a smaller file and control where it plays.

Lower the resolution

How do I make a video small enough to email?
Most mail providers cap attachments at 25 MB. Esporta at 480p on the "Small file" setting; for anything over a minute you may also need to trim it.
Does compressing a video reduce its quality?
Yes — that is the trade. Lowering the resolution usually looks better than lowering the quality at the same file size, because compression artefacts are more noticeable than a slightly softer picture.
Why is my exported file larger than the original?
Because the original was already efficiently compressed and re-encoding it added a generation. If you only need to cut the video, use the "Same as source" quality — it copies the streams instead of re-encoding.
Is there a file-size limit?
300 MB in, because the file is held in your browser’s memory. There is no limit on the way out.
Which is smaller, MP4 or WebM?
WebM, usually noticeably. MP4 plays everywhere, which is why it is the default.
