3GPP to 3GP Converter

How to Convert 3GPP to 3GP Online

1. Upload Your 3GPP File: Drag and drop your .3gpp file or click "Add Files" to browse. Batch is supported — queue several recordings at once.
2. Pick a Video Codec: Default keeps the source codec family (H.263 or H.264), re-encoded at the visually-lossless default preset. Choose H.264 for modern player support, H.263 for legacy feature-phone compatibility, or MPEG-4 if a downstream tool requires it. Pair with AAC or AMR (NB/WB) audio.
3. Resolution, Trim, and Quality (Optional): Pick a Preset Resolution (4320p, 2160p, 1440p, 1080p, 768p, 720p, 648p, 576p, 480p, 360p, 240p, 144p — these set height only, with the width following your clip's aspect ratio), scale by percentage, or set a custom Width × Height when you need an exact frame such as 176 × 144 (QCIF) or 320 × 240 (QVGA). If you pick the H.263 codec, note it accepts only 128×96, 176×144, 352×288, 704×576 and 1408×1152, and our layer snaps anything else to the largest of those that fits — so 320 × 240 becomes 176 × 144 there; H.264 and MPEG-4 take any even size. Trim with start time + duration in HH:MM:SS.sss. Tune output via Quality Preset (Highest → Lowest), CRF (18 visually lossless, 23 default, 28 smaller file), constant/variable bitrate, or a target file size in MB.
4. Convert and Download: Click "Convert" and grab the .3gp file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert 3GPP to 3GP?

3GPP and 3GP are the same multimedia container — both are defined by the 3rd Generation Partnership Project for UMTS/3G mobile networks and use the same MPEG-4 Part 12 (ISO base media) structure. The split is purely about file extensions: some recorders, players, and apps emit .3gpp, others emit .3gp, and a few tools accept only one. Converting between them here re-encodes the streams — there is no stream-copy mode — but the default keeps the source codec family and encodes at a visually-lossless preset, so the output looks and sounds the same while gaining the extension your tool accepts.

• Phone recordings the editor refuses to open — Older Android camcorder apps and voice recorders sometimes save as .3gpp. If your editor or NLE only sees .3gp, this produces a .3gp it will accept — a re-encode at the visually-lossless default, so the low-res source looks unchanged.
• Uploading to legacy CMS or feature-phone gateways — MMS gateways, kiosk uploaders, and some carrier portals match strictly on .3gp. The container is identical; only the extension is rejected.
• Voicemail and call-recording exports — VoIP apps and PBX systems frequently dump .3gpp with AMR-NB audio. Many transcription pipelines and audio editors expect .3gp.
• Archive normalization — When backing up old phone footage to NAS or cloud, picking one extension keeps the library consistent and improves search/scrub behaviour in media managers like Plex, Jellyfin, or VLC playlists.
• Web embeds and HTML5 <source> tags — Browsers map MIME types from extension; sticking to .3gp (video/3gpp) avoids the .3gpp MIME quirks some servers don't have configured.
• Cross-converting later — Once normalized to .3gp, downstream tools like 3GP to MP4 or 3GP to MOV work without per-file extension fiddling.

3GPP vs 3GP — Format Comparison

The two are the same container family. Note that this converter still re-encodes the streams rather than copying them — at the visually-lossless default the difference is invisible, but the output is a fresh encode, not a bit-for-bit copy.

Frequently Asked Questions

Is converting 3GPP to 3GP lossless?

Not bit-for-bit — converting here always re-encodes; there is no pass-through stream copy. The default flow keeps the source codec family and encodes at the visually-lossless tier, so the .3gp is indistinguishable from the source in normal playback even though it is a fresh encode. Changing the codec, resolution, or bitrate alters the output further; if you need a byte-identical archive, keep the original .3gpp alongside the converted file.

Can't I just rename the .3gpp file to .3gp?

Sometimes, yes. Because the underlying container is the same, a manual rename works in many players (VLC, MX Player, modern Android). It fails when an app validates the file via MIME sniffing or when an upstream pipeline rejects the source extension before it ever opens the bytes. This converter instead writes a clean, spec-conforming .3gp (re-encoding the streams in the process), which is more reliable.

Why do some phones save as .3gpp instead of .3gp?

It comes down to OEM defaults. Several Android camcorder apps, AOSP-based recorders, and older Sony/HTC firmware emitted .3gpp to match the spec name. Samsung, LG, and most carriers shipped recorders that wrote .3gp. Both files came off the same MPEG-4 ISO container code path.

Will my AMR audio still work after conversion?

Yes. AMR-NB and AMR-WB are native to the 3GPP container family, and the default conversion keeps the source audio codec family, so AMR stays AMR in the .3gp output (as a fresh encode — every conversion here re-encodes). If you'd rather have broader playback support (e.g., on desktop browsers or DAWs), pick AAC-LC at 96–128 kbps in the audio settings instead.

What's the largest file I can convert?

The browser is the limit, not a fixed quota. Mobile recordings rarely exceed 50–200 MB even at 1080p H.264, and the converter has handled multi-hundred-MB inputs. For very long captures, trim first via the Trim option (start + duration in HH:MM:SS.sss) to extract just the segment you need.

Does 3GP support 1080p or 4K, or is it a low-res format?

The container supports any resolution H.264 supports, including 1080p and 4K — there is no codec-level cap. In practice, 3GP files are usually QCIF (176×144), QVGA (320×240), or 480p because the format was designed for 3G bandwidth. If your source is 1080p smartphone video, output stays 1080p unless you pick a smaller preset.

Should I convert to MP4 instead?

If your only goal is wider compatibility, MP4 is a better long-term target — it shares the same MPEG-4 Part 12 base but is the de facto standard for browsers, social platforms, and editors. Use 3GPP to MP4 for that route. Stick with .3gp only when a specific tool, gateway, or device explicitly requires the extension.

Will the conversion strip my 3GPP Timed Text subtitles?

No. The .3gp container supports the same 3GPP Timed Text track type, so subtitles carry across the conversion. If you need the subtitles in a more portable format afterward, convert to MP4 and the timed text track typically maps to TX3G/MOV text.

Can I trim or crop while converting?

Yes. The Trim option takes a start time and duration in HH:MM:SS.sss format, so you can extract just the clip you need in the same pass. Cuts are frame-accurate because the trim happens as part of the re-encode, and the footage you drop is never encoded — so shorter selections also convert faster.
