BMP is uncompressed and dated; WebP is compact and modern. Converting BMP to WebP delivers the biggest possible size saving while keeping good visual quality — the best target for putting old bitmaps online.
These formats bookend three decades of image engineering: BMP saves pixels with virtually no compression, while WebP applies some of the most efficient compression any browser can decode. Converting old bitmap exports to WebP typically delivers the largest size reduction of any pairing on this site, in lossy or fully lossless mode.

When should you convert BMP to WebP?
- Drastically shrinking a BMP for a fast-loading website.
- Modernising legacy BMP assets into an efficient format.
- Cutting storage and bandwidth for large bitmap files.
- Converting a BMP export so it works in modern browsers.
How BMP and WebP compare
BMP is best for legacy desktop workflows — convert it to png, jpg or webp for any real use. WebP is best for web images and page-speed optimisation — the best default for most websites today.
Side by side, the practical differences between BMP and WebP look like this:
| Property | BMP | WebP |
|---|---|---|
| Compression | Uncompressed (lossless) | Both (lossy & lossless) |
| Transparency | No | Yes |
| Animation | No | Yes |
| Typical file size | Very large — pixels are stored with little or no compression | Typically 25–35% smaller than JPG/PNG at equivalent quality |
| Support | Universal on desktop; uncommon on the web | All modern browsers (Chrome, Firefox, Safari, Edge) since ~2020 |
| Best for | Legacy desktop workflows — convert it to PNG, JPG or WebP for any real use. | Web images and page-speed optimisation — the best default for most websites today. |
Things to keep in mind when converting BMP to WebP
- For typical images, going from BMP to WebP is straightforward — there are no meaningful downsides to watch for.
BMP to WebP: quality, file size and privacy
You decide the trade-off: the slider sets the WebP compression level, and for typical BMP images anything around 80 looks exactly like the original while shrinking the file substantially.
Your BMP files stay on your machine from start to finish. The page brings the tool to your browser rather than sending your images to a server — which is also why there's no queue, no daily cap, no watermark and no sign-up.
Frequently asked questions
Are my files uploaded when I convert BMP to WebP?
Never. There is no server-side processing: the BMP-to-WebP conversion happens locally on your machine, and no copy of your file exists anywhere else.
Is the BMP to WebP converter free?
Yes — every converter on ImgWand is free, BMP to WebP included. No sign-up, no watermark, no daily quota.
Can I convert many BMP files at once?
Yes — drop multiple BMP files and download them individually or as a single zip.
Is WebP supported by all browsers?
Yes. Chrome, Firefox, Edge and Safari (14 and later) all render WebP, so for the vast majority of visitors it simply works — keep a BMP fallback only if you must support ancient browsers.
Does converting to WebP work in every browser?
Creating WebP needs a browser with a built-in WebP encoder — Chrome, Edge and Firefox all have one. Safari can display WebP but can't produce it, so on Safari your BMP files are saved as PNG or JPG instead, with a note explaining the switch.
Will the WebP file be smaller than my BMP?
Almost certainly — BMP is uncompressed, so the WebP file is usually a small fraction of the original size.
Do I need to install software to convert BMP to WebP?
No — the converter is the web page itself. If your browser can open this page, it can convert BMP to WebP.
Will converting BMP to WebP reduce quality?
You control it. WebP uses adjustable compression; a quality around 80 looks identical to the original BMP for most images while keeping the file small.
