Finally got my FLAC collection on my phone

Had hundreds of FLAC albums that were too big for my phone. Profi PDF converted them all to MP3 overnight and now my whole library fits. Sound quality is still great.

Fast, clean, no drama

Converted a 500MB FLAC album to MP3 in under two minutes. Profi PDF is the cleanest free converter I've used — no ads, no watermarks, no sign-up wall.

Sent it over WhatsApp no problem

My FLAC file was way too big to send. Profi PDF converted it to MP3 and I sent it straight over WhatsApp. Took less than a minute total. Brilliant.

なぜこの音声・動画ツールを選ぶのか

Shrinks Without Sounding Bad

FLAC files are huge — great for audiophiles, rough for everyday use. Profi PDF converts them to MP3 at high bitrate so the audio still sounds sharp, just in a fraction of the file size.

Plays on Everything

MP3 is the universal audio format. Phones, smart speakers, streaming apps, car stereos — they all support it. Profi PDF gets your FLAC there in one click.

Share It Instantly

FLAC files are often too big to send over messaging apps or email. Profi PDF converts them to lean MP3s you can share anywhere without hitting size limits.

Batch Your Whole Library

Got an entire music collection in FLAC? Profi PDF lets you queue up multiple files and convert them back to back. No repetitive uploading, no wasted time.

Transcribe the Audio After

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

Encrypted & Auto-Deleted

Your FLAC is locked with encryption on upload and wiped from Profi PDF servers the second your MP3 is ready. Zero data stored, zero risk.
