Finally works on my old editing rig
My ancient video editor flat-out refused MKV files. PDF Paw converted them to AVI and now everything just works. Wish I found this sooner, honestly.

Stupid fast, zero quality loss
Converted a 90-minute MKV to AVI and it was done in under two minutes. Quality looked identical. PDF Paw is legit the best free tool for this.

No ads, no email, just works
Every other site I tried either wanted my email or bombarded me with ads. PDF Paw just converted my file and let me download it. Clean, simple, perfect.

Quality Stays Intact

PDF Paw converts your MKV to AVI without trashing the picture or audio. What you put in is what you get out — sharp, clean, no weird artifacts.

Batch It Up
