Need help?MRW to 3GP Converter
MRW is Minolta's raw photo format — a single high-bit-depth still straight off the camera sensor, not a video. 3GP is the 3GPP mobile-video container. This converter wraps one MRW photo into a short, silent 3GP clip that simply displays that single image, which is useful when a device or app will only accept a 3GP file. If you just want a viewable photo, convert MRW to JPG or PNG instead — those keep it as an image.
What You Should Know Before Converting
A few honest caveats, because MRW and 3GP are very different things:
- Still to video, not animation. An MRW holds one frame. The output 3GP shows that single image for a set duration — there is no motion and no animation.
- Silent by design. A photo carries no audio track, so the resulting 3GP clip is silent. 3GP can carry AMR or AAC audio, but there is none to add here.
- Raw to 8-bit. An MRW stores roughly 12 bits per channel (about 4,096 tonal levels per channel). A 3GP video frame is 8-bit (256 levels per channel), so most of the raw tonal range is discarded during conversion. Demosaicing — turning the sensor's raw mosaic into a viewable color image — also happens at this stage.
- Low resolution. 3GP was built for 3G mobile bandwidth and small screens, so it favors small frame sizes. Expect a much smaller image than the original MRW.

How to Convert MRW to 3GP
- Upload Your MRW File: Drag and drop your
.mrwfile or click "+ Add Files" to select it from your computer. - Set Image Duration and Background Color: Choose how long the still shows (Image Duration, default 5 seconds per frame) and the Background Color (default White) used to fill any padding.
- Pick Quality Preset and Video Resolution: Set the Quality Preset (default Very High) and choose Video Resolution — keep original, a fixed-resolution preset, or a custom width and height.
- Convert and Download: Click "Convert" and download your 3GP clip. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Why would anyone convert a RAW photo to a 3GP video?
Almost always because a target device or app accepts 3GP video but not an MRW raw still. Wrapping the photo in a 3GP container makes it playable as a one-frame clip on basic or older mobile hardware. For everyday viewing or sharing, converting MRW to JPG or PNG is the better choice.
Does the 3GP clip have any sound?
No. The source is a single photo with no audio, so the output 3GP is silent. The 3GP container can hold AMR or AAC audio in general, but there is no audio track to include when the input is a still image.
Will the conversion show the full quality of my MRW raw file?
No, and that is unavoidable. An MRW holds about 12 bits per channel of unprocessed sensor data; a 3GP video frame is 8-bit. The converter demosaics and tone-maps the raw data into a standard 8-bit image, so highlight and shadow detail beyond the 8-bit range is lost. Keep the original MRW if you may want to re-edit later.
Is the output an animation or a moving video?
No. It is one still image held on screen for the duration you set. There is no motion, no frame interpolation, and no animation — it is a single photo presented as a short 3GP clip.
What resolution will the 3GP file be?
Whatever you choose in Video Resolution. You can keep the original dimensions, pick a fixed preset, or enter a custom width and height. Because 3GP was designed for 3G mobile bandwidth, smaller frame sizes are typical, and you may want to downscale a large MRW for a genuinely mobile-friendly file.
Can I open the original MRW without converting it first?
Sometimes. Recent versions of Adobe Photoshop and Lightroom, XnViewMP, Apple Photos and Preview, and Windows Photos (with the Raw Image Extension) can open many MRW files. Support varies by camera model, which is one reason converting to a standard format is often easier than relying on raw support.
Are my files kept private during conversion?
Yes. In our testing, an MRW upload is transferred over an encrypted (TLS) connection, processed on our servers, and then deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public.
How long will the 3GP clip be?
As long as the Image Duration you set — the single rendered photo is held on screen for that time, with a default of 5 seconds per frame. There is no motion to time; the value simply controls how long the still is displayed before the short clip ends. Set a shorter duration for a smaller file, or a longer one if the clip needs to fill a set slot.
