Overview

A lot of "free" video converters are not actually free. The first 200 MB is free, the first three files are free, the first 720p output is free, after which the upgrade prompt appears. The pattern exists because running a server-side converter at scale is expensive. The operator pays for ingress bandwidth, encoder CPU time, storage for in-flight files, and egress bandwidth on the way back. Someone has to pay for that, which is why there is a paywall.

This tool side-steps the whole economic chain. The encoding runs in your browser on your device, so the operator's cost per conversion is essentially zero. The site itself is just static files served from a CDN. Genuinely free becomes a viable position because there is nothing to recoup.

Concretely: no signup, no email gate, no trial, no watermark. The practical limit is your device, not a paywall.

Technical notes

Why most "free" converters cap you

Server-side converters pay for ingress, CPU time, storage, and egress per job. The free tier is a loss leader funded by upgrades. Caps exist to limit the loss.

Why this one does not

Encoding runs in your browser, so the operator pays only for serving static page assets, pennies per thousand visits. There is nothing to recoup, so there is no cap.

What it costs to run

Static hosting on a CDN plus anonymized analytics. No upload bandwidth, no encode compute, no storage for in-flight files. The marginal cost per conversion is effectively zero.

Good to know

The cap is your device

There is no server-side cap, but encoding runs on your machine. Very large files and very long batches need free RAM, disk, and CPU/GPU time.

Browser support varies

WebCodecs is fully supported on recent desktop Chrome 94+, Edge 94+, Firefox 130+, and Safari 26+. Safari 16.4 to 25 work for most files but the implementation is partial, so some clips fail. Older browsers without WebCodecs cannot run the converter at all, and mobile browser support is improving but inconsistent.

Frequently Asked Questions

Is it really free with no catch?

Yes. No signup, no trial period, no watermark. The encoding runs on your device, so there is no per-job cost to recoup.

Will there be a paid tier later?

If anything is added it will be on top of what is here today, not behind a new cap. The free tier exists because it is the natural shape of the product, not a marketing funnel.

Are my files uploaded anywhere?

No. The conversion runs in your browser; nothing is sent to a server.

What is the catch?

The encoding runs on your device rather than a server, so very long batches can make your laptop's fans spin. That is the trade for no upload and a free price tag.

Which browsers does this work in?

Conversion uses the WebCodecs API. Fully supported: desktop Chrome 94+, Edge 94+, Opera 80+, Firefox 130+, and Safari 26+. Safari 16.4 to 25 work for most files but some may fail because their WebCodecs implementation is partial. Browsers without WebCodecs (Chrome/Edge <94, Firefox <130, Safari ≤16.3, Internet Explorer) cannot run the converter at all. Mobile browser support is improving but inconsistent, so a desktop or laptop is recommended for batch work.
