How to convert to BMP
This page converts any supported image into BMP. BMP stores pixels with no compression at all. That makes it simple and completely lossless, and it is still used by some Windows software and older imaging tools.
- Click the Choose Files button and select any images you want as BMP.
- BMP is already selected. Change it on any individual file if you want a mixed batch.
- Click Convert, then download your BMP files individually or as a ZIP.
Anything into BMP
JPG, PNG, WebP, AVIF, GIF, BMP and TIFF can all be turned into BMP here, in a single batch if you like, with no limit on how many files you drop in.
Keep the quality
Adjust quality per file and resize on the way through. Formats without transparency get a clean white matte instead of the black edges most converters leave behind.
Nothing is uploaded
Your files are read and written by your own browser. They are never sent to a server, so there is nothing to delete afterwards and no size or file-count limit.
More image tools
Everything below is built into this converter — no separate tool needed.
- Compress without converting — pick the same format as your input and lower the quality slider to shrink a file while keeping its type.
- Resize — open the gear on any file and set a maximum width; the height follows automatically.
- Images to PDF — choose PDF as the output to turn a photo or scan into a document.
- Make a favicon — choose ICO as the output to produce a browser icon from any square image.
What is a BMP file?
BMP stands for Bitmap. BMP stores pixels with no compression at all. That makes it simple and completely lossless, and it is still used by some Windows software and older imaging tools.
Files are very large — often ten times the size of the same image as PNG — and it has no place on a modern website.

Frequently asked questions
What can I convert to BMP?
JPG, PNG, WebP, AVIF, GIF, BMP and TIFF can all be converted to BMP on this page. Drop in a mixed batch and they will all come out as BMP.
What happens to transparency when converting to BMP?
BMP cannot store transparent pixels, so transparent areas are filled with white. If you need to keep transparency, convert to PNG, WebP or AVIF instead.
Is there a limit on file size or how many files I can convert?
No. Conversion runs inside your browser rather than on a server, so there is no upload, no queue and no cap.
Are my files uploaded anywhere?
No. Your files are read and written by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and the converter will still work.
