- Conversion starts right away. Download each BMP file, or click Download all to get them as one ZIP.
WebP vs BMP
| WebP | BMP | |
|---|---|---|
| Compression | Lossy or lossless | Uncompressed |
| Transparency | Yes | No |
| Animation | Yes | No |
| Colors | 8 bits per channel, full alpha | Usually 24-bit color, stored uncompressed |
| File size (photos) | Very small | Very large |
| Opens on | All modern browsers (Chrome, Edge, Firefox, Safari 14+); some older apps and editors cannot open it | Windows and most image viewers; rarely accepted on the web |
| Best for | Images on websites, where smaller files mean faster pages | Old Windows software, embedded devices and tools that need raw pixels |
About WebP and BMP
What is WebP?
WebP was created by Google to make web pages load faster. Lossy WebP is typically 25–35% smaller than a JPG of similar quality, and lossless WebP is about a quarter smaller than PNG. It also supports transparency and animation. Many websites now serve WebP automatically, which is why images you download often end up as .webp files that older software refuses to open.
- Much smaller than JPG and PNG
- Transparency and animation
- Lossy and lossless modes
- Not accepted by some upload forms, print shops and older apps
- Windows Photo Viewer and older Photoshop versions cannot open it
What is BMP?
BMP is an old Windows format that usually stores every pixel uncompressed. A photo saved as BMP can be 10–20 times larger than the same JPG. Today it is mostly needed for legacy software, some printers, industrial machines and microcontroller displays.
- Simple, uncompressed and lossless
- Readable by old and embedded software
- Enormous files
- No useful transparency or metadata
- Not accepted by most websites
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Will converting WebP to BMP reduce quality?
No. BMP is lossless, so the result looks exactly like your WebP. Converting cannot bring back detail the WebP compression already removed, though, and the BMP file will usually be bigger.
What happens to transparent backgrounds?
BMP does not support transparency, so transparent areas are filled with white. You can pick any other background color in the options.
Will the BMP file be smaller than the WebP?
Usually not. BMP files keep every pixel, so they are typically larger than WebP. If you need a small file, try WebP or compress the image.
Why do images I download save as WebP?
Many websites now deliver images as WebP because the files are smaller and pages load faster. Your browser saves the image exactly as it was delivered — which is why you end up with .webp files that older apps refuse to open.
Which kind of BMP is created?
A standard 24-bit uncompressed Windows bitmap that every program able to read BMP can open.
Can I convert several WebP images at once?
Yes. The free plan handles 10 images at a time, and you can download everything as a single ZIP. Pro removes the batch limit, converts files in parallel and supports files up to 4 GB.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
