Finally got my old home videos on my phone
Had years of family videos stuck in AVI that nothing would play. PDF Paw converted them all to MP4 and now they're on my phone and backed up to the cloud. Priceless.

YouTube stopped rejecting my uploads
Was uploading AVI files to YouTube and kept getting format errors. PDF Paw converted them to MP4 and everything went through first try. Should've done this ages ago.

Fast, clean, no watermarks
Converted a big batch of old AVI clips in one session. PDF Paw was fast, the quality held up perfectly, and there was no watermark or sign-up wall. Exactly what I needed.
