BMP to JPG Converter - Free Desktop App

BMP (Windows Bitmap) is an uncompressed image format created by Microsoft. It stores every pixel's color data without any compression, which makes files extremely large but preserves perfect quality. BMP was the default screenshot and image format in older versions of Windows (95, XP, Vista) and is still used by some legacy enterprise software.

BMP files store raw, uncompressed pixel data. A single 1920x1080 image in BMP format is about 6MB, while the same image as JPG is typically 200-500KB — that's 10-30x larger. This is because BMP records the exact color value for every single pixel without any compression algorithm to reduce file size.

There is minimal quality loss at high JPG quality settings (85-95%). Since BMP is uncompressed, you're starting with perfect pixel data. At 90% JPG quality, the visual difference is virtually imperceptible to the human eye, while file size drops by 90-95%. For most practical purposes, the converted JPG looks identical to the original BMP.

Yes. Drop entire folders of BMP files into Diwadi and convert them all to JPG at once. This is perfect for modernizing old image archives — convert thousands of legacy BMP files from old Windows systems, CD-ROM backups, or retired enterprise software in minutes.

Absolutely. BMP files from any era of Windows (95, 98, XP, Vista, 7) are all supported. Whether they're screenshots, saved images from old Paint, or exports from legacy software, Diwadi converts them to modern JPG format that works everywhere. The pixel data is preserved regardless of the BMP's age.

Some legacy enterprise applications, industrial control software, and older Windows programs still export images as BMP. Simply save or export from your software as usual, then use Diwadi to batch convert the BMP outputs to JPG. You can even set up a workflow to regularly convert a folder of BMP exports.

For photographs and general images, 85-90% quality provides an excellent balance of quality and file size. For screenshots with text, use 90-95% to keep text sharp. For web-only use where small file size is the priority, 75-80% still produces good results. Diwadi's quality slider lets you preview and adjust.

Dramatically smaller — typically 90-97% reduction. A 6MB BMP screenshot becomes a 200-400KB JPG. A 25MB BMP photo becomes a 500KB-1MB JPG. This makes converted files practical for email, web upload, cloud storage, and sharing where BMP's massive file sizes are completely impractical.

Yes. If you can read the BMP files from old CDs, DVDs, USB drives, floppy disk images, or hard drives, Diwadi can convert them. This is a common workflow for digitizing old photo collections or migrating legacy image archives to modern formats that are practical to store and share.

Convert your BMP files to JPG with Diwadi. Most web portals, government upload systems, job application sites, and corporate platforms accept JPG but not BMP. The conversion is instant, reduces file size by 90%+, and the resulting JPGs meet standard upload requirements. All processing is local — your files never leave your computer.
