3GP to MPG Converter

Convert 3GP to MPG Online

This tool re-encodes a 3GP file — the low-resolution container early-2000s phones recorded to — into an MPG (MPEG Program Stream), the 1990s desktop video format built on MPEG-1. It is a legacy-to-legacy conversion with one honest purpose: getting an old phone clip into older desktop software, a disc-authoring suite, or a media player that only reads MPEG program streams. Set expectations first — a 3GP source is already small and low-resolution, so converting to MPG cannot add detail back; the H.263 or MPEG-4 video is simply re-encoded to MPEG-1/MPEG-2, and AMR speech audio is re-encoded to MP2. If your goal is to actually modernize an old clip for phones, browsers, or smaller files, convert to MP4 instead.

How to Convert 3GP to MPG

1. Upload Your 3GP File: Drag and drop your .3gp (or .3g2) onto the page, or click "Add Files" to pick it from your device.
2. Pick the Video Codec: Under Advanced Options the video codec defaults to MPEG-2, what most disc-authoring tools expect for a program stream; choose MPEG-1 only if a Video CD or older device specifically requires it. Audio defaults to MP2.
3. Set Quality, File Size, or Trim (Optional): Use the Quality Preset dropdown (default Very High) or switch File Compression to "Specific file size" or "Constant Bitrate" to cap the output; keep "Keep original" under Video resolution since a low-res 3GP gains nothing from upscaling. Use Trim to export only a time range.
4. Convert and Download: Click Convert and save your .mpg. No sign-up, no watermark.

Frequently Asked Questions

Will converting 3GP to MPG improve the video quality?

No. A 3GP file is already low-resolution and lossily compressed, and converting it to MPG cannot recover detail that was never recorded — there is no upscaling that adds real information. The conversion re-encodes the existing picture into MPEG-1 or MPEG-2 video, which can introduce a small amount of additional loss. To keep that loss minimal, leave the resolution on "Keep original" and use a high Quality Preset rather than shrinking the frame or targeting a tiny file size.

Does this output MPEG-1 or MPEG-2 video?

MPEG-2 by default, which most disc-authoring and desktop playback tools expect from an .mpg program stream. You can switch the Video Codec dropdown to MPEG-1 if you are specifically targeting Video CD or an older device that requires it. Both produce a valid MPEG program stream; MPEG-2 is the safer general-purpose choice.

What happens to the AMR speech audio in my 3GP file?

Most 3GP clips from phones carry AMR-NB (narrowband) audio, which is a speech-optimized codec MPG containers do not use. During conversion the audio is re-encoded to MP2, the audio layer MPEG program streams expect. AMR is tuned for voice in a narrow frequency band, so re-encoding it does not make speech sound better — it just makes the audio playable in MPEG-1/MPEG-2 players. If your 3GP used AAC instead, it is likewise re-encoded to MP2.

Why would I convert to MPG instead of MP4?

Only for compatibility with something that will not accept MP4 — an older DVD or Video CD authoring pipeline, a dated editing suite, or a legacy player that reads only MPEG program streams. For anything modern (phones, browsers, messaging, and smaller files at the same quality), MP4 with H.264 is the better target. MPG is a fallback for legacy hardware and software, not an upgrade.

Is the .mpg output suitable for burning a disc?

Yes — that is its main use case. An MPEG-2 program stream with MP2 audio is the lineage Video CD and DVD-Video are built on, so the .mpg slots into authoring tools like DVDStyler. Because a 3GP source is low-resolution, a strict DVD-compliant disc may letterbox or rescale the picture; your authoring program enforces its own resolution and bitrate rules and may re-multiplex the stream.

How are my files handled, and how long do you keep them?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
