BMP converter
BMP stores images without compression and takes a lot of space. For the web, email and messengers it is converted to JPG, PNG or WebP to reduce size and ensure compatibility.

Why convert BMP
BMP is convenient for simple raster images but poorly suited to the internet because of its size. JPG reduces the weight of a photo, PNG preserves quality and transparency, WebP provides modern compression.
Which format to choose
For photos choose JPG, for graphics and screenshots choose PNG, and for websites choose WebP. All three open on most devices.
Format questions
Why is BMP so large?
BMP usually stores pixels without compression or with a simple scheme, so the file takes a lot of space. JPG, PNG and WebP are more efficient.
Is quality lost?
PNG and lossless WebP keep the image unchanged. JPG uses lossy compression, but at high quality the difference is usually invisible.
Can I convert BMP on a phone?
Yes, images are processed in the browser. The same 25 MB limit applies on mobile.
