Convert JPG to BMP

Convert JPG to BMP for legacy Windows tools that require uncompressed input. BMP is uncompressed — expect files 10–20× larger than the JPG source.

Bitmap (BMP) is an uncompressed raster format used mainly by legacy Windows applications and some scientific tools. Converting a JPG to BMP produces a dramatically larger file with no visible quality benefit — but some applications simply won't open anything else.

Browser Canvas doesn't natively encode BMP. This tool converts to PNG (lossless, same use case) — most tools that ask for 'BMP' accept PNG. If you strictly need .bmp, use a dedicated legacy converter after this step.

Frequently asked questions

How do I convert JPG to BMP?
Drop your JPG file into the tool above. It's converted to BMP in the browser and ready to download. Multiple files can be converted at once.
Why convert JPG to BMP?
Bitmap (BMP) is an uncompressed raster format used mainly by legacy Windows applications and some scientific tools. Converting a JPG to BMP produces a dramatically larger file with no visible quality benefit — but some applications simply won't open anything else.
Is any quality lost when converting to BMP?
Converting between lossy formats (like JPG to WebP) involves one round of re-encoding, so there is theoretically some quality loss — but at the default quality setting it's visually indistinguishable. Converting to a lossless format (PNG) doesn't lose data from the source.
Does the BMP file work everywhere the JPG did?
Modern browsers, image editors, and platforms all support BMP. Older tools (2015-era software, some third-party services) may not — if you need maximum compatibility, JPEG or PNG remain the safest fallbacks.
Are my files uploaded anywhere?
No. Conversion runs entirely in your browser using the Canvas API. Files never touch our servers, which matters for pre-publication work, client assets, or anything sensitive.
