Most 3GP recordings from 2003-2010 phones are 30 seconds to a few minutes long, so millisecond precision matters when you're isolating a single moment.3GP (3GPP file format) was published on 4 April 2003 by the 3rd Generation Partnership Project as a stripped-down container for video and audio on early 3G GSM handsets. It was the default capture format on Nokia (N-series, Asha, Symbian S60), Sony Ericsson (Walkman, Cyber-shot phones), pre-Galaxy Samsung, Motorola RAZR, and LG feature phones — devices with tiny screens (typically QCIF 176×144 or QVGA 320×240) and storage measured in megabytes, not gigabytes. 3G2 is the parallel CDMA2000 variant published in January 2004 by 3GPP2 for Verizon, Sprint, and KDDI handsets; structurally it is almost identical, both being based on ISO/IEC 14496-12 (the MPEG-4 base media file format).
Most people who still touch 3GP today are working with archives, not new recordings. Trimming lets you keep what matters and discard what doesn't, before re-sharing or re-encoding to a modern format.
.3gp files dumped to a PC over USB or Bluetooth. Trim out the 90 seconds that matter before converting; the original is often 5+ minutes of pocket footage..3gp ringtones and music videos often have radio-station tags, splash logos, or trailing silence. A clean trim makes the clip loop cleanly as a notification sound.| Property | 3GP | 3G2 | MP4 |

| Mode | When to use it | Behavior |
|---|---|---|
| (no compression change) | You only want to cut, not re-encode | Stream copy where possible — fastest, no quality loss |
| Quality Preset (Highest-Lowest) | You want a one-click size/quality tradeoff | Maps to a CRF/bitrate ladder behind the scenes |
| Constant Quality (CRF) | You want consistent visual quality | Lower CRF = better quality, larger file (H.264 typical 18-28) |
| Constant Bitrate | You need predictable streaming bitrate | Locks an exact kbps; quality varies with motion |
| Variable Bitrate | You want better quality per byte | Allocates more bits to complex scenes |
| Target file size (%) | You need the output ~X% of the input | Tool back-calculates a bitrate from duration |
| Specific file size | You need to hit a hard cap (e.g., MMS) | Tool back-calculates a bitrate to land near that size |
Yes — if you skip the "File Compression" section and only set a Time Range, the trim is performed by stream copy where the codec keyframe layout allows it, which is fast and lossless. If your start point falls between keyframes the tool will re-encode the leading GOP only, then stream-copy the rest, so quality stays at the source level.
None for the file you're holding. .3gpp is just an alternate extension for the same 3GPP container; the registered MIME type for both is video/3gpp. Some Android phones write .3gp and some Symbian/Nokia phones wrote .3gpp. xconvert accepts both.
Yes — .3g2, .3gp2, and .3gpp2 are accepted on the same page. 3G2 is the CDMA2000-side cousin of 3GP, defined by 3GPP2 in January 2004 for Verizon, Sprint, and KDDI phones. The two formats share the ISO/IEC 14496-12 base, so trimming works the same way; the only catch is that 3G2 cannot carry HE-AAC v2 or AMR-WB+ audio streams (3GP can).
No. AMR-NB is a narrowband speech codec sampled at 8 kHz with bitrates from 4.75 to 12.2 kbit/s — it was designed in 1999 for cellular voice, not music, and the upper frequency cutoff is around 3.4 kHz. Trimming preserves whatever quality is in the source. If you want fuller audio you'd need a clip that was recorded with AMR-WB (16 kHz) or AAC, which most 3GP recorders did not use by default.
3GP source files are already small (a 30-second QCIF clip is often under 1 MB). The container overhead is a few KB, so a 50% trim ends up ~50% the size, not dramatically smaller in absolute terms. If you need a smaller file, also enable "Constant Quality" or "Target file size (%)" under File Compression.
If the destination device or workflow accepts MP4, convert first with 3GP to MP4 and trim the MP4 — modern players, social platforms, and editors handle MP4 natively, while 3GP support has been dropped from many newer apps. Keep the output as 3GP only if you're targeting a feature phone, an old in-car infotainment system, or you want byte-identical container parity with the source.
Native support is patchy in 2026. Android historically shipped a system 3GP decoder, but newer OEMs sometimes omit the H.263 codec; iOS plays many 3GP files in the Files app but not all. The reliable cross-platform approach is to install VLC or convert to MP4. If you only need to view it once, VLC is faster.
This page handles a single Time Range per file. To remove sections from the middle, trim once for the front segment, trim again for the back segment, and merge the outputs — or convert to MP4 first and use the video cutter, which has a friendlier multi-segment workflow.
The xconvert browser session runs locally — practical limits are your machine's available memory and your network upload speed, not a hard server cap. 3GP files almost never exceed a few hundred megabytes given the format's typical bitrates (under 384 kbps for video on most feature-phone recordings), so you'll rarely run into limits with this format specifically.
