Frequently Asked Questions

Is WebP better than JPG?

Yes, for web use. WebP files are 25–35% smaller at the same visual quality, and WebP supports both lossy and lossless compression as well as transparency. All modern browsers support WebP as of 2026.

Does converting JPG to WebP reduce quality?

At quality settings of 80 or above, the visual difference between JPG and WebP is virtually invisible. WebP achieves smaller file sizes through a more efficient compression algorithm, not by discarding more visual information.

Can I convert JPG to WebP without software?

Yes. Resizo converts JPG to WebP entirely in your browser using the HTML5 Canvas API. No software download, no upload, no sign-up required. Works on desktop and mobile.

Will all websites and apps accept WebP files?

Most do. All major browsers, CMS platforms (WordPress, Squarespace, Webflow), and social media platforms (Instagram, Twitter, LinkedIn) accept WebP. Some older tools or email clients may still require JPG — in those cases, keep a JPG backup.
