BMP to JPG Converter In your browser, nothing uploaded
EXIF metadata is removed. Decoding and redrawing the image carries no GPS coordinates, camera model or timestamp across, so the file you download has none of it. If you need that data kept, copy the originals instead.

What is JPG?
JPG is the format photographs settled on. It was standardised in 1992, and essentially every device built since then can read one. The compression is lossy. It discards the fine detail human vision is least sensitive to, which is how it reaches such small files, and what it discards does not come back. At sensible quality settings you will not see the difference in normal viewing at all. There is no transparency channel. JPG also handles text and hard edges badly, leaving visible ringing around every letter, which is why screenshots, diagrams and anything with lettering in it belong in PNG instead — a rule that holds however good the source bitmap was. For photographs nothing beats it on practicality, largely because nothing anywhere refuses to open it.
What is a BMP File?
BMP (Bitmap) is an uncompressed image format developed by Microsoft. BMP files are very large because they store every pixel without compression. Converting BMP to modern formats dramatically reduces file size while preserving quality.
BMP vs JPG
BMP is barely a compressed format at all. A Windows bitmap generally writes every pixel out as raw bytes, so the file size is roughly width times height times bytes per pixel, whatever the image happens to contain. A 4000x3000 photo lands around 36 MB. So does a 4000x3000 rectangle of flat grey. JPG applies real compression tuned to how eyes work, and the same photograph typically ends up between 1 and 4 MB. What you give up is exactness. BMP is lossless. JPG is not. On a photograph at the default quality it is a difference you will never see. For screenshots and diagrams, convert to PNG instead: lossless, and still enormously smaller than the bitmap.
Why Convert BMP to JPG?
- Because the bitmap stores raw pixels, a 12-megapixel photo costs about 36 MB, where the same picture as a quality-92 JPG lands somewhere between 1 and 4 MB, which is the entire argument in one line.
- Once you are past a 25 MB attachment ceiling, which a BMP of any size manages easily, the JPG is what actually sends.
- When 200 screen captures have been saved as BMP, the folder runs to gigabytes.
- Since no website serves BMP and no CMS expects it, publishing anything at all means converting first, whatever your browser happens to be willing to display on its own.
- If you want the trade-off in your own hands, the slider starts at 92.
Frequently Asked Questions
How much smaller will the JPG be?
For photographic content, usually 90 to 98 percent smaller. BMP stores raw pixels, so its size is driven by dimensions rather than by content: a 12-megapixel image is roughly 36 MB as a 24-bit BMP no matter what is in it. The same picture as a quality-92 JPG typically lands between 1 and 4 MB, and where it falls in that range depends on how much fine detail the photo carries.
Why are BMP files so enormous?
Because the format was designed in the late 1980s for direct display on Windows, where reading a file straight into video memory mattered more than what it cost on disk. It writes out each pixel's colour value in sequence. There is an optional run-length encoding that almost nothing uses, no perceptual compression, no entropy coding of any consequence, and no attempt to exploit the resemblance between neighbouring pixels that every modern codec is built on.
Will I lose image quality?
Some, technically. BMP is lossless, JPG is not, and the conversion throws some of the information away permanently. At 92 you will not see it on a photograph without pixel-peeping. Screenshots, scans and charts are a different matter. JPG produces visible ringing around sharp edges. Send those to PNG instead. It is lossless and still vastly smaller than the bitmap.
What happens to transparency in a 32-bit BMP?
It is discarded. Those areas come out black. BMP can carry an alpha channel in its 32-bit variants. Most tools never write one. JPG supports no transparency whatsoever. Something has to fill those pixels, and here it is black — not white, which is what people expect and why the result looks broken rather than subtly wrong. It catches people converting logos. If the bitmap carries transparency that you care about, send it to PNG instead of JPG.
