Frequently Asked Questions (FAQs)
Is there a file size limit?
The tool can handle most standard image sizes, but extremely large files (50MB+) may cause performance issues.
Are my images stored on your servers?
No. All processing happens in your browser - your images never leave your device.
Can I adjust settings after conversion?
You'll need to reprocess the original with new settings, as B&W conversion is destructive.
Why choose WebP output?
WebP typically offers 30% smaller file sizes than JPEG at similar quality.
How does this compare to Photoshop?
While not as full-featured as Photoshop, it provides specialized B&W tools in a simpler, faster package.
