About the format
Video compression stores most frames as differences from neighboring frames rather than complete pictures — the inter-frame trick that makes modern codecs like H.264 so effective.
- H.264/AVC, the most widely supported video codec, was standardized jointly by ITU-T and MPEG in 2003 and was designed to halve the bitrate of MPEG-2 at the same quality.
- Phones record at generous bitrates for editing headroom, not for sharing — which is why re-encoding typically shrinks recordings 50-90% with modest quality impact.
- FFmpeg, the open-source engine this tool runs (compiled to WebAssembly), has been in continuous development since 2000 and powers much of the world's video infrastructure.
About this conversion
Video files from phones and screen recorders are enormous because they're encoded in real time at generous bitrates — the camera can't spend minutes deciding how to pack each frame, so it spends bits instead. A slower, deliberate re-encode routinely shrinks such files 50-90% at visually similar quality, which is the difference between "file too large" and sent.
This compressor runs FFmpeg — the same engine behind most of the world's video infrastructure — compiled to WebAssembly inside your browser. Nothing uploads: a 500 MB recording of your screen, your kids or your meeting is processed on your own CPU. Three modes cover the real cases: a quality level for general shrinking, a resolution cap (4K screen recordings rarely need to stay 4K), and a target-size mode that hits an exact limit like 25 MB for email or Discord.
The quality trade-offs: re-encoding is lossy, so compress the final cut, not footage you'll edit further. Fine, fast-moving detail — confetti, water, dense text scrolling — is where lower settings show first. Medium quality is visually close to the original for typical phone and screen content; when you must hit a hard cap, target-size mode makes the size-versus-sharpness decision explicit instead of trial-and-error.
When not to compress: already-small clips (a re-encode can't help what's already tight), master copies you're archiving, and footage headed into an editor. For those, keep the original and compress the exports. Everything else — attachments, uploads, chat clips — benefits, and the network tab will confirm none of it left your device.
Frequently Asked Questions
How much can my video be compressed?
Phone and screen recordings typically shrink 50-90% at the default quality, because their original bitrate is far higher than needed. The target-size mode lets you hit an exact limit, like 25 MB for email or Discord.
Is compressing here really private?
Yes. Traditional compressors upload your video to their servers. Here the encoder (FFmpeg compiled to WebAssembly) runs inside your browser — the video never leaves your device, and you can verify that in your browser's network inspector.
What settings should I use?
Start with Medium quality — it's visually close to the original at a fraction of the size. Add a resolution cap (1080p or 720p) for big screen recordings, or switch to target-size mode when you must fit a specific upload limit.
Is there a file size limit?
Files up to about 1.5 GB are supported. Because processing happens in your browser's memory rather than on a server, very large files depend on your device's available RAM.
Every conversion runs 100% in your browser — zero files uploaded, ever.

Who we are — and what we refuse to do
We're a small team that got tired of "free" converters treating your files as the product.
So we built Converting Free the only way we'd trust ourselves: the whole toolbox — image, document and archive converters, compressors, time-zone and unit tools, calculators and text utilities — does its work on your device. Open your browser's network tab while you convert something; you'll watch nothing leave.
We don't run ads, we don't set tracking cookies, and we don't operate a server that stores files. That isn't a privacy-policy promise — it's how the site is engineered. There is simply nowhere for your data to go.
Why we built it
Search for "convert X to Y" and the top results usually want something from you before they'll lift a finger:
- —Your file, uploaded to a server you know nothing about
- —Your patience, spent on queues, captchas and "premium speed" upsells
- —Your data, harvested by the trackers stacked beneath the ads
We think a converter should be a tool, not a trade.
Ours takes nothing from you: no uploads, no accounts, no tracking.
