Higher means better sound and a larger file. “Auto” keeps the bitrate of the original (at least 128 kbit/s); from lossless files it uses the format’s high-quality setting.

Shown by e-readers in the library; leave empty to keep what the document says.

PDF/A-2b embeds all fonts so the file looks the same in many years; required by many courts and public offices.

Scales every sheet so it fits on a single page instead of being split across several.

Sheets

CSV and TSV hold one table: with “Every sheet” each sheet becomes its own file, together in a ZIP.

Separator

Excel in many European languages expects a semicolon; most other programs a comma.

About this tool

3GP is the classic video format of older mobile phones: very small files made for slow networks and small screens. M4R is the iPhone ringtone format: AAC sound of up to 40 seconds.

This converter takes the sound of your 3GP video and saves it as M4R, the right choice for ringtones and alert sounds on the iPhone – for example the music of a clip, a recorded talk, lecture or interview, or the sound of your own phone videos. The sound keeps its quality by default; under “Options” you can choose the bitrate, mono or stereo, and cut out just the part you need. The picture and the video’s own data (such as the camera or the place it was filmed) are not copied into the audio file.

Files are converted on our server: the upload starts only after you confirm, the original is deleted after conversion and the result is kept for 7 days unless you delete it sooner.

Frequently asked questions

How do I convert 3GP to M4R?

Choose or drop your 3GP video, keep M4R as the output and click Convert. After you confirm the upload, our server saves the sound of the video as M4R and you download it.

Can I convert a YouTube video to M4R?

We do not download videos from YouTube or any other website – that is against their terms of use. If you have the video file itself, for example a video you made and downloaded from YouTube Studio, or a clip saved on your phone or computer, drop it here and you get its sound as M4R.

Will the sound keep its quality?

Yes. The sound is converted at high quality: “Auto” keeps the bitrate of the video’s own sound (at least 128 kbit/s). You can choose another bitrate under “Options”.

Can I keep only part of the sound?

Yes. Under “Options” enter a start and/or end time (for example 1:05 and 3:30) and only that part is saved.

How large can the video be?

Each file can be up to 300 MB and 10 hours long, and you can add up to 10 at once.

What happens to my video?

It is uploaded only after you confirm. The video is deleted as soon as the sound is saved, and the M4R file is kept for 7 days unless you delete it sooner.

Can I use the M4R file as an iPhone ringtone?

Yes. iPhone ringtones play at most 40 seconds, so the M4R file is cut to 40 seconds from the start time you choose under “Options” (the beginning by default). Add it to your iPhone with Finder, iTunes or GarageBand.
