What changes from BMP to WEBP

QualityCompressed at high quality (90%): a small loss that’s hard to see
Colour depthSaved at 8 bits per channel
File sizeUsually smaller: WEBP compresses more tightly than BMP

When to use WEBP: Images on websites, where smaller files help pages load faster.

Options

  • Quality: maximum, high, medium or small file

The two formats

.bmp

BMP imageWindows Bitmap

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.

Opens in Paint, Photos, Preview, most image editors and browsers

Questions

How do I convert BMP to WEBP?

Drop your BMP file on this page, or choose it. Anyfile converts it on your device in a moment and the WEBP downloads straight away. To change it first, open it in the photo editor.

Is my BMP file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Will I lose quality?

WEBP is a compressed format, and Anyfile saves at high quality, so the difference is very hard to notice. For no loss at all, keep the BMP.

Can I convert several BMP files at once?

Yes. Drop them together and you get one ZIP with every WEBP inside.
