Can I convert MOS to BMP on iPhone, Android, Mac or Windows?

Yes. ConvertPixels works in Safari, Chrome, Edge and Firefox on any device, so you can convert MOS to BMP on your phone or computer without installing an app.

Is there a free MOS to BMP converter with no sign-up?

Yes, this one. Converting MOS to BMP on ConvertPixels is free, with no sign-up, no watermark and no daily cap. Convert up to 30 files per batch, each up to 50 MB.

Can I convert MOS to BMP without losing quality?

Yes. BMP is a lossless format, so your converted file is pixel-for-pixel the same as the MOS. (It can't add back detail the original never had.)

Can I batch convert MOS to BMP?

Yes. Add up to 30 MOS files and convert them in one batch. You can even choose a different output format for individual files, then download them separately or together as a ZIP.

Is it safe to upload MOS files to ConvertPixels?

Yes. Uploads use an encrypted connection and are processed automatically - nobody views them. Your originals are deleted straight after conversion and the results within an hour, or instantly if you click "Delete from server now".

MOS to BMP

Why convert MOS to BMP?

The main difference: MOS is an unprocessed sensor data format, while BMP is a lossless format.

Develop RAW into a ready-to-use photo

A MOS file holds the raw readings from the camera sensor, not a finished picture. Converting it to BMP applies the camera's colors and gives you a normal photo you can share, print or post right away.

Where BMP works best

BMP is ideal for legacy Windows software (files are very large). Converting gives you a file that works in the apps and websites that ask for BMP.

MOS vs BMP: what's the difference?

Property	MOS	BMP
Compression type	Unprocessed sensor data	Lossless (exact pixels, larger files)
Transparent background	No	No
Animation	No	No
Where it opens	None (needs a RAW editor)	Most browsers, rarely used on the web
Used for	Straight-from-camera photos for editing	Legacy Windows software (files are very large)

What is an MOS (camera RAW) file?

MOS is the camera RAW format of Leaf - Leaf medium-format digital backs. Instead of a finished photo, a RAW file stores the unprocessed data straight from the camera's sensor.

That gives photographers maximum room to adjust exposure, white balance and color afterwards, but RAW files are large (often 20-60 MB) and need special software to view. Converting to JPG produces a normal photo you can share right away.

How to open an MOS (camera RAW) file

Capture One opens MOS files, and Adobe Lightroom, Photoshop (Camera Raw), Capture One, darktable and RawTherapee support them too. Mac Photos and Preview open most RAW formats; on Windows, the free Raw Image Extension adds support to the Photos app. Without any of these, convert MOS to JPG online.

Extension: .mos
Made by: Leaf cameras
Contains: Unprocessed sensor data
Best for: Editing straight-from-camera photos

What is a BMP file?

BMP (bitmap) is Microsoft's original Windows image format. It stores pixels with little or no compression, so it's simple and lossless but very large - a 12-megapixel photo can top 35 MB.

BMP is mainly found in older Windows software, some industrial and embedded systems, and scanner output. For almost every other use, PNG gives the same quality at a fraction of the size.

How to open a BMP file

Windows Photos and Paint open BMP files, as does Mac Preview. Most browsers can display them too. Convert to PNG for a lossless copy that's much smaller, or JPG for photos.

Extensions: .bmp, .dib
Compression: None (usually)
Transparency: Rarely supported
Best for: Legacy Windows software
