Why use this converter?
BMP’s uncompressed format leads to enormous files, while WebP is engineered for compact storage and fast page loads. Converting is a great move when you’re preparing images for a website, store listing, or app and want every kilobyte to count. WebP also supports an alpha channel, so any transparency in your BMP is preserved in the output rather than flattened. Because the entire conversion runs locally in your browser, even hefty BMP files process quickly and your image is never sent to a server.

Frequently asked questions
Why convert BMP to WebP?
BMP files are large and uncompressed. WebP uses modern compression to deliver the same image in a much smaller file, which is ideal for websites and apps.
Is my file private and secure?
Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.
Is it really free, with no watermark?
Yes. The converter is free, unlimited, and watermark-free, with no sign-up needed.
Does WebP keep transparency?
Yes. WebP supports an alpha channel, so transparent areas in your BMP are preserved in the converted file.
What is a BMP file?
BMP (Bitmap) is a Windows format that stores pixels without compression, resulting in very large files. WebP is a modern format that stores the same content far more efficiently.
