Video compressor online free: complete online guide

Updated 2026-09-24 · 5 min read

Video compressor online — compress video for free in your browser to reduce video file size and make video smaller before you share. Upload MP4/WebM up to 25 MB; H.264 re-encode with ffmpeg.wasm — files stay on your device like VidShift-style local tools, not FreeConvert/Clideo server uploads for multi-GB files. We do not promise “compress 1 GB to 10 MB” or lossless 90% shrink — honest CRF 28 MP4 out.

What is Video compressor online free and who is it for?

Video compressor online free — compress video in your browser (25 MB max), reduce video file size with ffmpeg.wasm locally. Make video smaller for email or chat — not 2 GB cloud compress or guaranteed 90% shrink like FreeConvert ads.

Searches for “video compressor” usually mean a file already on your phone or laptop — not a YouTube/TikTok URL. This guide points to the upload workbench and honest limits (25 MB, browser wasm) versus cloud tools with huge caps.

Targets “compress video online,” “reduce video file size,” “make video smaller online,” and “compress video for free” — local wasm vs cloud compressors with huge limits.

How to use Video compressor online free on Peraspera Tools (step by step)

Follow the same four-step pattern on the live tool page — optimized for mobile and desktop browsers.

1. Upload video — MP4, WebM, MOV — max 25 MB per file.
2. Compress — H.264 + AAC encode in your tab.
3. Wait — First visit loads wasm — keep tab open.
4. Download — Smaller MP4 to Downloads.

Compress video online (browser-local)

These utilities run ffmpeg.wasm in your tab — Peraspera does not store your upload on our servers. First visit downloads the encoder; keep the tab open until export completes.

Maximum upload size is 25 MB per file. That is smaller than many cloud compressors advertising multi-gigabyte queues — by design for privacy and mobile stability.

Choose a file from your device (MP4/WebM/MOV where the browser can decode).
Adjust any fields shown on the workbench (times, crop pixels, output format, etc.).
Click Process & download and check your Downloads folder.
For YouTube or TikTok URLs, use the link-based downloader or MP3 pages instead of upload tools.
