BMP files are huge and rejected by most websites. Converting to WebP fixes that: much smaller than JPG and PNG.
Drop one BMP or a hundred — they’re converted inside your browser, so even private photos are never uploaded anywhere.
BMP vs WebP
| BMP | WebP | |
|---|---|---|
| Compression | Uncompressed | Lossy or lossless |
| Transparency | No | Yes |
| Animation | No | Yes |
| File size | Huge — no compression at all | 25–35% smaller than JPG at the same quality |
| Compatibility | Windows apps; rarely accepted online | All modern browsers; some older apps and upload forms still reject it |
| Best for | Old Windows software | Websites and online stores that need fast-loading images |
Good to know before converting BMP to WebP
- WebP supports transparency, but converting won’t remove a background by itself — use Remove background for that.
- WebP files are smaller, but double-check that the app or site you’re uploading to accepts WebP.
- Hidden data like GPS location and camera details is left out of the converted file.
What is BMP?
BMP is an old Windows format that stores every pixel with no compression at all. Files are enormous and almost no website accepts them, so converting is nearly always a good idea.
What is WebP?
WebP was made by Google to make websites load faster. It does everything JPG and PNG do — including transparency — in noticeably smaller files. The catch: plenty of desktop apps, government portals and older software still can’t open it.
How to convert BMP to WebP
- Drop your BMP files (or paste with Ctrl+V).
- WebP is already selected — adjust quality if you like.
- Download one by one or all as a ZIP.
Frequently asked questions
Does converting BMP to WebP reduce quality?
Only very slightly. WebP is lossy or lossless; at the default quality the difference is practically invisible. Raise the quality slider for maximum fidelity.
Can I convert many BMP files at once?
Yes — drop as many as you like and download them all as one ZIP.
Are my images uploaded to a server?
No. Everything happens inside your browser on your own device. Your images are never uploaded, stored or seen by anyone — check your browser's Network tab, or turn on airplane mode after the page loads and see that it still works.
Is it really free?
Yes. No sign-up, no watermark, no daily limits and no paid “HD” downloads.
Do downloads still contain my location?
No. Every file you download is saved without hidden metadata like GPS location, camera serial number or owner name.
