Convert video FAQs

How does video convert work without upload?

ffmpeg.wasm runs in your browser to re-encode media locally.

Is convert video free?

Yes — free and private, limited mainly by your device performance.

Will large videos be slow?

Yes. Local convert uses your CPU/GPU; large files are slower than cloud GPUs but stay private.

Do you upload my files?

No. GroundPDF processes files entirely in your browser with WebAssembly. Files never leave your device — nothing is uploaded to a server.

Is it free?

Yes. Free to use with no account and no daily limits.

Which devices and browsers work?

Any modern browser with WebAssembly support: Chrome, Firefox, Safari, and Edge on desktop or mobile.

How is this different from iLovePDF or Smallpdf?

Those tools upload your files to the cloud. GroundPDF runs on your device (on the ground, not in the cloud), so your documents stay private by design.
