Finally plays on my TV
Had a bunch of MKV movies that my Smart TV refused to play. PDF Paw converted them all to MP4 and now everything works perfectly. Took like 5 minutes total.

Zero quality loss, seriously
Was worried about losing quality converting a 4K MKV. PDF Paw remuxed it perfectly — same sharpness, same audio. Couldn't tell the difference.

Por Qué la Gente Elige Nuestras Herramientas de Audio y Video

Plays Literally Everywhere

MKV is great but not universal. MP4 works on iPhones, Android, Smart TVs, YouTube, and every video editor out there. PDF Paw gets you there fast.

No Quality Loss

PDF Paw remuxes your video without re-encoding when possible, so the picture and audio quality stay exactly as they were in the original MKV.

Handles Big Files

MKV files can be massive — full movies, multi-episode rips, 4K footage. PDF Paw chews through large files without choking your browser.

Batch Convert

Got a whole folder of MKVs to convert? PDF Paw lets you queue them up and knock them out one after another. No repetitive uploading.

Transcribe the Audio After

Once you have your MP4, run it through PDF Paw AI transcription to pull out subtitles, captions, or a full text transcript. One platform, full workflow.

Encrypted & Auto-Deleted

Your video is encrypted on upload and wiped from PDF Paw servers the moment conversion is done. Zero data stored, zero risk.
