How to convert BMP to JPG
- Choose your files. Click Select File or drag your BMP files into the upload box. You can add many at once.
- Pick the settings. JPG is already selected as the output format. Adjust Quality and Max dimension if you want smaller files.
- Download. Each file appears in the list when it is ready. Download them one by one, or all together with Download all.
Why convert BMP to JPG?
BMP is an old Windows format that stores images without compression, so even a simple screenshot can be several megabytes. Converting to JPG usually makes the file 10 to 20 times smaller, ready to email or upload.
When to keep the BMP
There is rarely a reason to keep BMP, except for old software or devices that only read BMP. For graphics with sharp edges consider BMP to PNG instead.
Tips for the best result
- Quality 80 to 90 keeps screenshots and scans clear.
- For diagrams, logos and screenshots with lots of text, PNG keeps edges sharper than JPG.
- Upload a whole batch of BMP files and download a ZIP.
Common problems and fixes
- Text looks slightly blurry.
- Use a higher Quality, or convert to PNG, which is lossless.
- The file will not open.
- Some programs write unusual BMP variants. Open it in Paint and save it again as BMP, then convert.
BMP
BMP – Bitmap
BMP is a simple image format from Windows that usually stores pixels with little or no compression, so files are large compared with JPG, PNG or WebP. It is rarely used on the web, and converting a BMP is the easiest way to make it small enough to share.

JPG – Joint Photographic Experts Group
JPG (also written JPEG) is the most widely used format for photographs. It uses lossy compression, which keeps files small by discarding fine detail the eye is unlikely to miss. It does not support transparency or animation, and virtually every device, browser and app can open it.

Converting BMP to JPG
- JPG files are usually smaller than BMP files at similar visual quality, so converting BMP to JPG typically saves storage and speeds up page loads.
- JPG cannot store transparency, so any transparent areas are filled with white.
- BMP files are often uncompressed, so the converted file is frequently dramatically smaller.
Frequently asked questions
Why are BMP files so big?
Most BMP files are uncompressed: every pixel is stored in full. JPG and PNG compress the same image dramatically.
Should I use JPG or PNG for a BMP?
JPG for photos and scans, PNG for screenshots, drawings and anything with text.
How do I convert BMP to JPG?
Click Select File or drop your BMP file onto the upload box. Pick the quality and maximum size, and the converted JPG appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
