How do I reduce 3GP file size?
You can reduce 3gp file size by setting a specific desired output file size or reduce by percentage.
-
To reduce 3GP below a certain size, enter your desired file size in MB. E.g. 5 MB or 0.5 for 500KB and click "Next".
-
To reduce 3GP by percentage, click the "By Percentage" tab and enter your desired percentage reduction. E.g. 30 for 30% file size reduction and click "Next".
You will be redirect to the correct file compression page. The page contains further instructions for reducing 3GP file size.
Enter the size you need in megabytes and ezyZip compresses the 3GP file to fit under it. Common targets are 5MB, 10MB, 16MB, 20MB, 25MB and 100MB, and any other value works just as well. Choose one from the list below, or type your own into the size box at the top of this page. Files are processed inside your browser, so nothing is uploaded.
Choose how much smaller you want the file to be. Reducing by 50% halves it, and reducing by 80% leaves a fifth of the original size. ezyZip works out the target for you and compresses the 3GP file to match. Choose a percentage from the list below, or type your own into the box at the top of this page.
Pick a smaller frame height and ezyZip re-encodes the video to match. 1080p, 720p, 480p, 360p, 240p and 144p are the usual choices. The width is worked out for you so the picture keeps its original shape, and the lower the resolution the smaller the finished file.

Why client-side 3GP media compression keeps your content private
ezyZip compresses 3GP media using a full WebAssembly-compiled codec library running locally in your browser. Here is why local media compression is technically superior:
- Local Codec ExecutionCompiled codec libraries run locally on your CPU, delivering the same encoding quality as desktop transcoding software. The WASM build includes optimized codec implementations that produce professional-grade output.
- Multiple Compression StrategiesChoose between target file size, percentage reduction, or resolution scaling — each mode uses a different optimization strategy tailored to that compression goal, with adaptive algorithms that adjust parameters for your specific content.
- Dual-Mode CompatibilityMulti-threaded primary execution via SharedArrayBuffer with automatic single-threaded fallback ensures consistent performance across all modern browsers. The engine detects your browser's capabilities and selects the optimal execution mode automatically.
- No Restrictions or WatermarksThere are no file size limits, no watermarks stamped on output, no daily processing caps, and no queue wait times. You get unrestricted access to the full codec library with no artificial limitations.
