WEBP to BMP converter: free, fast and secure
This free WEBP to BMP converter turns your WEBP images into BMP files in seconds, right in your browser. Images saved from websites are often WEBP, and many photo editors, printers and upload forms still reject that format. Converting to BMP fixes the “file type not supported” error. Some older Windows software, embroidery machines and industrial printers only accept uncompressed BMP files.
Unlike most converters, ConvertKaro never uploads your images. The conversion happens on your own device, so it is quicker, there are no file limits, and your photos stay private.
How to convert WEBP to BMP in 3 steps
- Add your WEBP files. Tap “Select files” or drag and drop one or more .webp images into the box above. You can also paste a screenshot with Ctrl+V.
- Adjust the options. The default settings work for most images, so you can skip this step.
- Download your BMP. Conversion starts instantly. Download each BMP file, or all of them at once as a ZIP.

What is WEBP?
WEBP is a modern image format released by Google in 2010. It produces files roughly 25–35% smaller than JPG at similar quality, supports transparency like PNG and can even hold animation. Most websites now serve WEBP to load faster. The catch is compatibility: some older Windows photo viewers, editing apps, printers and upload forms still refuse WEBP files.
What is BMP?
BMP is the classic Windows bitmap format. It stores every pixel without compression, so the quality is perfect but the files are huge: a normal phone photo can become 10–30 MB. Today BMP is mostly used by older Windows programs, embroidery and printing machines, and some industrial software that expects raw pixel data.
When should you convert WEBP to BMP?
- Legacy Windows software
- Embroidery, laser and industrial machines
- Programs that need raw, uncompressed pixels
- Some school and lab software
Tips for the best BMP results
- If your image has a transparent background, pick a background colour that matches where the image will be used.
- You can convert many WEBP files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original WEBP files until you have checked the converted BMP images.
How WEBP to BMP keeps your photos and images private
Most online converters upload your file to their server, process it there and send it back. That costs time, uses your data pack and means a copy of your file sits on someone else’s computer. WEBP to BMP works differently: the page loads the tool into your browser, and your photos and images are processed by your own phone or computer. The file never travels over the internet, so it cannot be leaked, stored or misused.
Using WEBP to BMP on your phone
WEBP to BMP is designed for small screens. Buttons are large, options are simple, and downloads save directly to your phone storage. On iPhone, downloaded files appear in the Files app under Downloads; on Android they go to the Downloads folder.

Frequently asked questions
Will converting WEBP to BMP reduce quality?
BMP stores the image none, so no extra quality is lost during conversion.
Does BMP keep transparency from WEBP?
BMP does not support transparency, so transparent areas are filled with a background colour. White is the default, and you can pick any colour before converting.
Can I convert multiple WEBP files to BMP at once?
Yes. Select or drop as many WEBP images as you like. Each one is converted separately, and you can download them all together as a ZIP file.
Why are images on websites saved as WEBP?
Websites use WEBP because it is much smaller than JPG and PNG, which makes pages load faster. When you save such an image, you get a .webp file that some apps cannot open.
Is WEBP to BMP really free?
Yes. WEBP to BMP on ConvertKaro is 100% free with no limits, no signup and no watermark. There is no paid version.
Is it safe to use WEBP to BMP online?
It is one of the safest ways to do it, because nothing is uploaded. All processing happens locally on your device, and the files disappear when you close the page.
Does WEBP to BMP work on mobile?
Yes. It works in Chrome and Safari on Android phones and iPhones, as well as on tablets and computers. No app is needed.
Is there a file size limit in WEBP to BMP?
No upload means no server limit. The only limit is your device’s memory, which comfortably handles everyday files and even large batches.

No. There is no watermark, no login and no email required. Your downloaded file is exactly your result.
Does WEBP to BMP work offline?
