- Extreme compression - shrink files by 95-99% compared to BMP
- Modern format - optimized for web with transparency support
- Adjustable quality - fine-tune the balance between size and visual quality
Frequently Asked Questions
How much smaller will the WebP file be?
WebP compression typically reduces BMP file size by 95-99%. A 10 MB BMP can become a 200 KB WebP file with excellent visual quality.
Does WebP support transparency?
Yes. Unlike BMP, WebP fully supports alpha transparency, so you can add transparent backgrounds after conversion if needed.
Is WebP better than converting to JPG or PNG?
For web use, yes. WebP produces smaller files than both JPG and PNG while supporting transparency and both lossy and lossless compression.
Is this tool really free?
Yes, completely free with no hidden fees, no watermarks, and no sign-up required. You can convert as many files as you need.
Are my files private and secure?
Absolutely. Every conversion runs in an isolated, in-memory process. Your files never touch the disk, are never stored or shared, and are deleted from memory the moment your download is ready.
