GIF export is a still frame (first frame of an animated GIF). No extra library is used.

Turn bulky BMP files into WebP

BMP is an uncompressed bitmap. A single screenshot can be tens of megabytes — unusable on a website or in a WhatsApp share.

Converting BMP to WebP (or JPG/PNG) is often a 90%+ size cut because you are leaving an uncompressed format, not just re-encoding a JPEG.

Upload one BMP or many. Everything stays local. Then download WebP, or pick PNG/JPG if you need a more compatible still.

Frequently Asked Questions

Why are BMP files so large?
BMP stores raw pixels with little or no compression. WebP and JPG store the same picture much more efficiently.
Can I convert BMP to JPG or PNG too?
Yes. Use the output format buttons on this page.
Does this work for large screenshots?
Yes, within your browser’s memory. Very huge bitmaps may be slow on older phones.
Are BMPs uploaded to a server?
No. Conversion is client-side only.
Can I convert a folder of BMPs?
Select multiple files in the picker or drop several at once, then download a ZIP.
Is BMP common on the web?
Almost never. Convert to WebP or JPG before publishing.
