Free tool
Anyfile makes a BMP image smaller for free, right in your browser: nothing is uploaded. Drop it below and the smaller copy downloads at once.
Files are converted in your browser and never uploaded. By using Anyfile you agree to the Terms of Use.
Anyfile re-encodes the picture with the best balance of size and quality for it, and may switch a picture with no need for its format to PNG or JPG (a BMP becomes a PNG, a TIFF a JPG). Very large pictures can be scaled down to a sensible size. If it can’t make the file smaller, it keeps the original and says so.
.bmp
Microsoft’s bitmap format from the early days of Windows. It usually stores pixels uncompressed, so quality is exact but files are large.
Older Windows software, simple paint programs and tools that expect raw, uncompressed pixels.

About BMP filesYes, for sharing, email and the web: it’s compressed with care, and the card shows exactly how much smaller it got. For printing or further editing, keep the original.
It depends on the BMP: photos saved at maximum quality and uncompressed formats shrink a lot; already-compressed ones less. The card shows the new size before you use it.
No. It’s compressed in your browser, on your device; nothing is sent to a server.
Yes. Drop them together and choose Make it smaller: you get one ZIP with every smaller file.
