BMP to JPG Converter

Why use this converter

Your files stay with you

Everything runs on your device. Images are never uploaded to a server, so nobody else ever sees them.

Much smaller files

BMP usually stores images uncompressed, while JPG compresses them — for photos and screenshots the difference is usually several times.

MozJPEG encoding

JPGs are created with Mozilla's MozJPEG encoder. You can adjust the quality with the slider.

Batch conversion

Convert up to 100 images at a time and download them as a single ZIP file.

Frequently asked questions

What is a BMP file?

BMP is an old Windows image format. It usually stores every pixel uncompressed, so files are large, and many websites and messaging apps don't accept them.

How much smaller will the file get?

It depends on the image, but usually several times smaller, since BMP is usually uncompressed. Each file's row shows the size before and after.

Will I lose quality?

JPG compression is lossy, so the image changes slightly. At the default quality of 90 the difference is usually invisible. If you need an exact copy, choose PNG — it's also much lighter than BMP.

Which BMP files are supported?

Practically all you'll come across: 1, 4, 8, 16, 24 and 32 bits per pixel, with or without RLE compression, including files with transparency and an embedded color profile.

What happens to transparency?

JPG has no transparency, so transparent areas are placed on a white background. To keep transparency, choose PNG or WebP.

Is it safe to convert my images here?

Yes. The site only downloads the converter itself; your images are processed in your browser and are never sent to a server.
