Add your WEBP file
Drop one or more .webp files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
WEBP to BMP
Converting a .webp image to .bmp re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .webp image to .bmp re-encodes the pixels for a different balance of size, quality, and support. A .webp file is Google's web-oriented image format, offering both lossy and lossless compression plus alpha and animation in one container. At equivalent visual quality, .webp files typically undercut JPEG by 25-35 percent, which is why CDNs and site optimizers convert to it aggressively.
A .bmp file is the Windows bitmap format: raw pixel rows written to disk with a small header and, in the common case, no compression at all. Its brute simplicity makes .bmp trivial to read and write from any programming language, which is why it persists in tooling, embedded systems, and quick debugging dumps. For this route the practical draw is dead-simple structure with no decoding step at all and exactly lossless — what you write is what you read — balanced against no effective compression, so files dwarf PNG equivalents of the same image, which is worth knowing before you commit a large batch.
Why convert WEBP to BMP?
The practical trigger for this conversion is usually a mismatch: with .webp, mandatory 4:2:0 subsampling in lossy mode caps color fidelity below high-quality JPEG or AVIF. Switching to .bmp buys you dead-simple structure with no decoding step at all, which is why it is the better fit for quick lossless dumps from code, since a writer takes minutes to implement. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
WEBP vs BMP at a glance
| Aspect | WebP image (.webp) | Bitmap image (.bmp) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | lossy mode encodes VP8 intra frames with block prediction; lossless mode uses its own dedicated coding with spatial predictors and color transforms | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | serving photos and graphics on websites where bandwidth and Core Web Vitals matter | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | mandatory 4:2:0 subsampling in lossy mode caps color fidelity below high-quality JPEG or AVIF | no effective compression, so files dwarf PNG equivalents of the same image |
Pick BMP as the output
Select .bmp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if BMP is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid BMP file. Outputs keep the original filename with the .bmp extension.
WEBP to BMP questions, answered
Will converting WEBP to BMP lose quality?
No new loss is introduced — since webp is lossy-oriented and bmp is lossless-oriented, everything the .webp file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .bmp does not "restore" quality.
Is it private to convert WEBP files here?
Yes — the .webp file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the BMP file work?
Windows treats BMP as a native citizen, and macOS, Linux, and all major browsers open it without complaint. The format's problem is never support but waste: emailing or hosting uncompressed bitmaps burns bandwidth for zero benefit, so converting to PNG is almost always an upgrade.
Will the BMP file be bigger or smaller than my WEBP?
Larger, sometimes much larger. A lossless .bmp must store every pixel or sample the decoder produced, without the perceptual shortcuts .webp used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my WEBP file?
In .webp, eXIF and XMP travel in dedicated RIFF chunks and ICC profiles are supported, though a fair amount of conversion software strips metadata by default when writing WebP. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert BMP back to WEBP?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .webp → .bmp → .webp is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
