Frequently asked questions

How much smaller will the WebP be compared to BMP?

Often 80-90% smaller, since BMP stores pixels with no compression at all while WebP applies efficient modern compression. A heavy uncompressed BMP becomes a compact, web-ready file that loads quickly on a page.

Will I lose visible quality?

At standard quality settings the difference is invisible for most images, while the file becomes dramatically smaller and web-friendly. For graphics that must stay pixel-perfect, lossless WebP keeps every detail at a smaller size than BMP.

Should I pick lossy or lossless WebP?

Use lossy WebP for photographs, where the small size matters most and the quality loss is invisible. Choose lossless WebP for screenshots, logos and diagrams with sharp edges, where you want no artefacts around lines or text.

Which browsers can display the WebP?

All current versions of Chrome, Edge, Firefox and Safari support WebP, so it displays everywhere the modern web reaches. Only very old browsers miss it, where a PNG fallback covers the gap.

Does the WebP keep transparency from the BMP?

If the BMP has an alpha channel, WebP preserves the transparency. Most BMP files are opaque, so there is usually nothing transparent to carry over and the image converts cleanly.

Why is the BMP so large in the first place?

BMP stores every pixel as raw uncompressed data, so even a simple image can be many megabytes. WebP replaces that with efficient compression, which is why the size drop is so dramatic.

Can I convert several BMP files to WebP at once?

Yes. Add a whole folder of BMP files and each becomes its own compact WebP in a single pass, with nothing merged and no limit on the number of files. Each source gives its own WebP.
