People Also Use
Turn your WebP files into BMP right in the browser — this tool will grow each file and hand it back in seconds, with nothing uploaded to any server. WebP is Google's modern format that does both lossy and lossless, typically 25–35% smaller than JPEG or PNG at the same quality. BMP is an uncompressed Windows bitmap: every pixel is stored raw, so quality is exact but files are very large. Because BMP has no transparency, any transparent areas are flattened onto a background colour you choose. Free, private, unlimited, and watermark-free.
How to Convert WebP to BMP
Add your WebP file
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to BMP
Press Convert. BMP is lossless, so every pixel is preserved exactly.
Download
Save each BMP file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert WebP to BMP?
The main reason is exact pixel data with zero compression, occasionally required by legacy Windows software. WebP excels at web images where small size matters, but when you need pixel-perfect quality, BMP is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
BMP is a lossless format, so the conversion preserves your image exactly — no detail is discarded in the BMP encoding itself.
A note on file size
Note that BMP files are usually larger than WebP — BMP stores 24-bit uncompressed colour, so this trades size for compatibility.
About WebP
WebP is Google's modern format that does both lossy and lossless, typically 25–35% smaller than JPEG or PNG at the same quality. Best for web images where small size matters, with transparency and animation supported in one format.
About BMP
BMP is an uncompressed Windows bitmap: every pixel is stored raw, so quality is exact but files are very large. Best for exact pixel data with zero compression, occasionally required by legacy Windows software.
Common Uses for WebP to BMP
- Converting WebP to BMP for a project that specifically requires Bitmap files, where WebP is not accepted.
- Preparing images for software or systems that only read BMP.
- Batch-converting a whole folder of WebP images to BMP at once, instead of doing them one at a time.
- Switching a WebP export into BMP so it opens correctly in the tools your team actually uses.
- Archiving WebP images as lossless BMP so no further quality is lost over time.

| Transparency | Supported | Not supported |
| Animation | Supported | Not supported |
| Colour depth | 24-bit colour with optional alpha | 24-bit uncompressed colour |

| Best used for | web images where small size matters | exact pixel data with zero compression |
Tips & Things to Know
Check the file size after converting
Note that BMP files are usually larger than WebP — BMP stores 24-bit uncompressed colour, so this trades size for compatibility. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Choose a background colour
Because BMP has no transparency, any transparent areas are placed on a background colour (white by default, and adjustable) so nothing turns black or breaks.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your WebP files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
The conversion is faithful
BMP is lossless, so every pixel is preserved exactly as it was in your WebP, meaning you do not have to worry about settings — just convert and download.
Frequently Asked Questions
How do I convert WebP to BMP for free?
Add your WebP file above and press Convert. The BMP download appears in seconds. It is completely free, with no signup, no limits and no watermark.
Is my WebP uploaded to a server?
No. The entire conversion runs inside your browser using your device's own processor, so your images never leave your computer. That matters for private photos and confidential work.
Can I convert multiple WebP files at once?
Yes. Add as many as you like and they are converted in one batch, then offered individually or as a single ZIP download.
Will converting to BMP reduce quality?
No. BMP is lossless, so the conversion keeps every pixel. Any quality limit comes only from the original WebP, not from this step.
Does BMP support transparency?
No, BMP has no transparency. Transparent areas are filled with a solid background colour (white by default) during conversion.
Why is my BMP file larger than the WebP?
BMP stores 24-bit uncompressed colour without lossy compression, so it is naturally larger than WebP. This is expected and the image quality is fully intact.
What is the difference between WebP and BMP?
WebP is Google's modern format that does both lossy and lossless, typically 25–35% smaller than JPEG or PNG at the same quality. BMP is an uncompressed Windows bitmap: every pixel is stored raw, so quality is exact but files are very large. That difference is what this conversion is really about.
Is there a file size limit?
Because processing happens in your browser, very large images depend on your device's memory, but typical photos convert instantly. Nothing is capped by an upload limit.
Do I need to install anything?
No. This works in any modern browser on any device — Windows, Mac, Android or iPhone — with nothing to install.
Is this WebP to BMP converter really free?
Completely free, forever, with no account, no watermark and no hidden premium wall.
