Built for the upload limits you actually hit

For Discord

Discord caps free uploads at 25 MB and the old 8 MB limit still trips a lot of servers. Compress to fit either ceiling without losing clip readability — VidCompress targets the exact size you choose and gets you under the line in one shot.

For Email

Gmail and Outlook draw the line at 25 MB attachments. Pasting a 200 MB video into a thread bounces silently. Compress to 24 MB, attach normally, skip the cloud-link friction — VidCompress preserves enough quality at email sizes that the recipient still sees what mattered.

For Web

Auto-play hero videos and product clips on landing pages need to load in under a second. Compress to 1-2 MB, lazy-load the rest, and watch your LCP score recover. WebM output keeps the file even smaller with modern-browser support that's now effectively universal.

Who uses an online video compressor

Four scenarios where a free online compressor saves more time than installing FFmpeg locally.

Discord Users

Your friend says "send me a clip" but Discord rejects the 80 MB raw recording you screen-captured. Free Discord servers cap uploads at 25 MB, and a lot of communities still have the older 8 MB limit. Drop the video into VidCompress, pick the Discord preset (or a custom MB target), and the compressor renders a clip that fits whichever ceiling your server enforces. The output stays watchable — Discord's playback at 720p is the practical quality floor, and the compressor targets it without going further.

Content Creators

Recording at 4K is the default now; uploading at 4K to every platform is a waste. YouTube re-encodes anyway, X downsizes ruthlessly, TikTok rejects long files. Use the compressor as the final step before each platform upload — 1080p for YouTube, 720p for TikTok and Instagram Reels, 4 MB for Twitter previews. Batch processing on the Pro plan handles the platform matrix without you opening Premiere again.

Students

Class recording is 500 MB. The LMS accepts 100 MB. The professor wants the file by midnight. VidCompress targets a custom size, so you say 95 MB and the encoder hits it. Keep the audio quality intact (the talking is the point), drop the resolution to 720p which is fine for most lecture content, and submit. The compressed file is on the LMS in under three minutes from your first drag-and-drop.

Small Businesses

Your product video is 200 MB on the marketing folder. The agency-built website asks for sub-5 MB to keep the page fast. The freelancer who built the site is unreachable. VidCompress turns 200 MB into 4 MB in one pass. WebM output for modern browsers cuts another 30% off. Drop the file into the CMS, preview the page, ship it before the next standup.

Frequently asked questions

How do I compress a video online for free?

Drag your video onto the upload area at the top of this page (or click to browse). Pick a target size — Discord, email, web, or custom MB — and click Compress. The compressed file downloads when it's done. No signup, no watermark, no email gate.

What video formats are supported?

MP4, MOV, AVI, MKV, WebM, and WMV are all accepted as input. Output is MP4 by default; WebM is available if you need the smaller-but-modern format for web embedding.

Will compressed video lose quality?

Some, yes — that's how compression works. The trade-off is the point: you're picking how much quality to give up in exchange for a smaller file. For most use cases (Discord clips, email attachments, web embeds) the quality at the target size is still very usable. For archival or master-quality preservation, don't compress at all.

Is there a file size limit?

Free users can compress files up to 100 MB. The Pro plan ($4.99/mo) lifts the limit to 5 GB and adds batch processing, 4K input, and no watermark on output. Files under 300 MB are processed entirely in your browser — they never touch our servers.

Can I compress videos for Discord?

Yes. Pick the Discord preset (8 MB for free servers, 25 MB for boosted) and the compressor targets exactly that size. You can also enter a custom MB value if your server has unusual limits.

Is there a watermark on compressed videos?

No. Free output has no watermark. We don't believe in the watermark-as-friction model — it just trains users to look for a competitor's tool. Pro features are paywalled on capability (size limits, batch, 4K), not on watermarks.

Need batch compression or 4K?

Pro = $4.99/mo · up to 5 GB per file · batch up to 10 videos · 4K input · no watermark.
