Extracted my lecture audio instantly

Had a bunch of WebM screen recordings from online classes and needed just the audio. PDF Maxi converted them all to MP3 in minutes. Absolute time saver.

Fast and the quality is legit

Converted a 2-hour WebM recording to MP3 and the audio was crystal clear. PDF Maxi is the cleanest free converter I've found — no ads, no drama.

No sign-up, no watermark, just works

Tried three other sites before this. All wanted accounts or slapped watermarks on. PDF Maxi just did the job and let me download. Staying here.

なぜこの音声・動画ツールを選ぶのか

Ditch the Video, Keep the Sound

WebM files can be chunky. PDF Maxi pulls out just the audio as a lean MP3 — perfect for sharing clips, making podcasts, or archiving voice content without the video overhead.

Crystal Clear Output

PDF Maxi extracts and encodes your audio at high bitrate so the MP3 sounds clean and sharp. No muffled output, no weird compression artifacts — just good audio.

Great for Browser Recordings

Screen recorders and browser tools often save as WebM. PDF Maxi converts those recordings to MP3 so you can share the audio anywhere — no compatibility grief.

Batch Convert in One Go

Got a pile of WebM files to process? PDF Maxi lets you queue them up and convert back to back. Fast, efficient, no repetitive clicking.

Transcribe It Right After

Once you have your MP3, run it through PDF Maxi AI transcription to get an accurate text transcript, subtitles, or captions. Full workflow, one platform.

Private by Default

Your WebM is encrypted on upload and wiped from PDF Maxi servers the moment your MP3 is ready. Nobody sees your files — ever.
