3GPP to WebM Converter

Convert 3GPP to WebM Online

Turn an old .3gpp (or .3gp) phone clip into WebM — the open, royalty-free format that plays inline in every modern browser, so you can embed feature-phone footage on a personal site or family-history page with a single HTML5 <video> tag. 3GPP is the GSM-era mobile container most desktop players refuse to open; WebM was built by Google in 2010 specifically for the web. The honest catch: those clips were recorded tiny and soft for 3G networks, and no converter adds detail that was never captured — the output stays small and low-resolution, and the win is playability, not sharpness.

How to Convert 3GPP to WebM

1. Upload Your 3GPP File: Drag and drop or click "Add Files" to select .3gpp or .3gp clips — saved MMS attachments, Nokia / Sony Ericsson / early-Motorola recordings, or footage dumped off an old camera card. Batch is supported; drop several at once.
2. Pick a Video Codec and Quality Preset: Default output is VP9, WebM's modern web codec. Choose AV1 for the smallest file on 2022-and-newer devices, or VP8 for the broadest legacy compatibility. The Quality Preset dropdown ("Very High" down to lower presets) trades size for fidelity; or use Specific file size to cap the output in MB.
3. Set Resolution and Audio (Optional): Under Video resolution, "Keep original" avoids upscaling the source's blur; Preset Resolutions or Width x Height let you scale deliberately. Audio defaults to Opus (switch to Vorbis for older WebM tooling), and the Trim control lets you cut a Time Range to drop any dead lead-in.
4. Convert and Download: Click Convert. 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.

3GPP vs WebM — What You're Trading

Because the source is already low-resolution, going above the original width just enlarges blurry pixels — keep "Keep original" or a matching preset. For device playback over iMessage / WhatsApp instead of web embedding, convert 3GPP to MP4 so H.264 plays natively on iOS and Android. If your clips are saved with the shorter spelling, the extension-twin page 3GP to WebM runs the identical workflow.

Frequently Asked Questions

Will the video look sharper after converting to WebM?

No, and no online tool can fix this. The source 3GPP was encoded at low bitrates for 2G / 3G cellular networks, typically at 176×144 or 320×240, so block artifacts and color banding are baked into the original. Upscaling the resolution doesn't add detail — it just enlarges blurry pixels. The conversion moves that footage into a modern, royalty-free container browsers can actually play; if you want it to look better on a big screen, run a separate AI upscaler after converting.

Should I pick VP9, AV1, or VP8 for the WebM output?

VP9 for almost everything — universal modern-browser support and more efficient than the H.263 inside most 3GPP files. AV1 when you want the smallest possible file and your audience is on 2022-or-newer devices; encoding takes longer but the result is meaningfully smaller. VP8 only for very old Android or extremely conservative legacy embeds, which is rarely needed now. All three are royalty-free, which is the main reason to choose WebM over the patent-encumbered codecs in the original 3GPP.

Will the AMR audio survive, and will it sound better?

The audio survives but won't improve. 3GPP voice is usually AMR-NB (narrowband, 8 kHz, roughly 4.75-12.2 kbps) or AAC-LC on later clips; it's re-encoded to Opus (WebM's default) or Vorbis. Speech stays intelligible, but a speech codec already discarded the high frequencies during the original recording, so phone-quality audio stays phone-quality — re-encoding can't recover what was never stored.

Is .3gpp the same thing as .3gp?

Yes — they're two extensions for the same container, defined by the 3rd Generation Partnership Project for GSM-based 3G handsets. The underlying ISO base media structure, codecs, and metadata are identical; .3gp is just the more common spelling. This tool treats them interchangeably. The separate .3g2 extension is the CDMA-network variant (3GPP2), a near-identical container with a few different voice codecs.

Why is my converted WebM bigger than the original 3GPP file?

Because 3GPP files are tiny by design — they target cellular bandwidth, so a couple of minutes is often only a few megabytes. In our testing, a 30-second QVGA-source 3GPP at the default VP9 quality landed around 3 MB, larger than the 1-2 MB original. WebM reserves more bitrate for video and audio at default quality; to match the original footprint, drop the Quality Preset or set a target in Specific file size. You're trading a slightly bigger file for browser compatibility the original codec can't offer.
