Finally works on my old editing rig

My ancient video editor flat-out refused MKV files. Profi PDF 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. Profi PDF 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. Profi PDF just converted my file and let me download it. Clean, simple, perfect.

なぜこの音声・動画ツールを選ぶのか

Old-School Compatible

AVI is the OG video format — it works on legacy players, older hardware, and classic editing software that chokes on MKV. Profi PDF gets you there in one click.

Quality Stays Intact

Profi PDF 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.

Windows-Friendly Output

AVI was built by Microsoft and plays natively on Windows. If your workflow is Windows-heavy, Profi PDF makes sure your video fits right in.

Batch It Up

Got a stack of MKV files to convert? Profi PDF lets you queue them up and knock them out back to back. No repetitive uploading, no wasted time.

Transcribe the Audio Too

Once your AVI is ready, run it through Profi PDF AI transcription to pull out subtitles, captions, or a full text transcript. One platform, full workflow.

Encrypted & Auto-Deleted

Your file is locked with encryption on upload and wiped from Profi PDF servers the second conversion is done. Zero data stored, zero risk.
