About WEBP and BMP
WebP .webp
Google's image format, designed to replace both JPEG and PNG. It can compress either way — lossy for photographs, lossless for graphics — and supports transparency and animation in both modes.
Good for
- Typically 25–35% smaller than JPEG at comparable quality
- Transparency in lossy mode, which JPEG cannot do at all
- One format covers photographs, graphics and short animations
Trade-offs
- Older software and some print workflows still will not open it
- Lossy WebP discards detail just as JPEG does
- Editing tools support it less consistently than PNG or JPEG

BMP .bmp
Microsoft's plain bitmap. It generally stores pixels with no compression at all, which makes it simple to read and very large on disk.
Good for
- Dead simple — every pixel stored literally
- No compression artefacts of any kind
- Reliably readable by old Windows software
Trade-offs
- Enormous files, often ten times a PNG of the same image
- Effectively unusable on the web
- Transparency support is inconsistent between readers

| Typically used for | Web images where size matters | Legacy Windows software, intermediate working files |
What changes when you convert WEBP to BMP
Only the first frame survives
Most WEBP files are still images and convert straightforwardly. WEBP can also hold an animation, though, and BMP cannot: if yours is animated, what you get back is its first frame and nothing else. Convert to a video format, or to another animating image format, if the motion matters.
Expect a very large file
BMP generally stores every pixel with no compression at all, so the result is often several times the size of the WEBP it came from while looking exactly the same. It is worth choosing only for old Windows software that will not read anything else.
Camera data is removed by default
A WEBP straight from a phone or camera carries EXIF metadata — model, settings, timestamp and, quite often, the GPS coordinates of where the photo was taken. The converted BMP is written without it, so a file you are about to share does not quietly carry your location. The orientation flag is read and applied to the pixels first, so the image will not come out sideways once the tag holding it is gone. If you need the metadata kept, there is a setting for it.
How the BMP is written
Our default is stored as plain uncompressed pixels, since that is essentially all BMP offers. The quality control on the converter moves this if you need to — the default aims to be indistinguishable from the source at a sensible file size, rather than to win a compression benchmark.

Why your PNG is so much bigger than your JPEG
The same photograph can be 300 KB as a JPEG and 4 MB as a PNG. Here is what each format is actually doing, and how to tell which one your file wants to be.

Where your transparent background went
Transparency is the property most often lost silently in a conversion — the file looks perfect until it lands on a coloured background and grows a white rectangle.
