BMP Files Are Too Large for the Web
You have BMP files that need to go online, but they're massive. A single BMP image can easily be 10-50 MB because the format stores every pixel without compression. That's fine for archival storage, but it's completely impractical for websites, emails, or sharing online.
WebP solves this problem. Developed by Google, WebP uses advanced compression to reduce file sizes by 90-95% compared to BMP while keeping images visually identical. In our testing, a 15 MB BMP screenshot converted to just 420 KB as WebP-a 97% reduction with no visible quality loss.
How to Convert BMP to WebP
- Upload your BMP file - Drag and drop or click to select your bitmap image
- Choose WebP format - WebP is selected for optimal web compression
- Download your WebP - Get your compressed image ready for use
The entire process takes seconds. No software to install, no account required.
BMP vs WebP: Understanding the Difference
BMP (Bitmap) is one of the oldest image formats, dating back to Windows 3.0 in 1990. It stores images without any compression, which preserves perfect quality but creates enormous files.
WebP was created by Google in 2010 specifically for the web. It uses both lossy and lossless compression algorithms to achieve much smaller files:
- File size - WebP is typically 90-95% smaller than BMP
- Quality - WebP maintains visual quality even with aggressive compression
- Features - WebP supports transparency and animation; BMP doesn't
- Browser support - Over 96% of browsers support WebP natively
For web use, WebP is superior in virtually every way.
When to Convert BMP to WebP
Website Images
If you're adding images to a website, WebP should be your default choice. Smaller images mean faster page loads, better Core Web Vitals scores, and improved SEO rankings.
Legacy System Exports
Many older programs and systems export screenshots or graphics as BMP. Converting to WebP makes these files practical for modern use without losing the original quality.
Email Attachments
BMP attachments often get blocked or cause delivery issues due to size. WebP attachments go through without problems and load faster for recipients.
Online Storage
Cloud storage costs money. Converting BMP archives to WebP can reduce storage needs by 90% or more while keeping images accessible.
Quality Considerations
WebP offers both lossy and lossless compression options. Our converter uses high-quality settings that preserve image detail while achieving significant size reduction.
For photographs and complex images, you won't notice any difference between the original BMP and the converted WebP. For graphics with sharp edges and text, WebP's lossless mode ensures pixel-perfect conversion.
If you need a format that's even more universally compatible, consider BMP to PNG for lossless compression or BMP to JPG for photographs.
