3GP to WIM Converter
Processing entirely on your device — large files may take a moment.
3GPP Mobile Video and Windows Imaging Format exist for different jobs: 3GP is the ultra-compressed video format old feature phones used. Modern players often cannot open these recordings. Extracting WIM to ZIP exposes the files inside Windows images without deployment tools.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
!Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it
About the WIM format
WIM (Windows Imaging Format) is how Microsoft ships Windows itself: the install media and deployment images are WIM files, holding a complete filesystem snapshot with single-instancing (identical files stored once). It is Windows' answer to tar — file-based rather than sector-based.
Opening one without deployment tooling (DISM, 7-Zip on Windows) is awkward. Extracting WIM to ZIP exposes the files inside — drivers, scripts, provisioned apps — on any system, no Windows required.
+Strengths
- ✓Windows' native image format
- ✓Single-instancing deduplicates identical files
!Limitations
- −Opaque without Microsoft tooling
- −Files inside may be Windows-locked
Why convert 3GP to WIM?
Think of it as moving your file to the container that fits the job. Very low resolution and quality ceiling WIM works differently: Windows' native image format If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this 3GP to WIM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for 3GP to WIM?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting 3GP to WIM re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
