My screen recordings finally work everywhere

I record tutorials in WebM and nothing would play them outside Chrome. PDF Maxi converted them all to MP4 and now they work on every device my clients use. Total lifesaver.

Fast, clean, no drama

Converted a 1-hour WebM lecture to MP4 in under two minutes. Quality was spot on. PDF Maxi is genuinely the best free tool I've used for this — no fluff, just results.

No sign-up, no watermark, perfect

Every other site I tried slapped a watermark on or demanded an account. PDF Maxi just converted my WebM and let me download it. Bookmarked immediately.
