JPG vs WebP: Which Format Is Better for the Web
Published: 2026-09-16
File Size and Compression
WebP typically produces 25-35% smaller files than JPG at a similar visual quality, thanks to a more modern compression algorithm. This makes it a strong choice for websites where page load speed matters.
Browser and App Support
WebP is supported by all modern browsers, but some older software, email clients, and photo-editing tools still expect JPG. If you're sharing images outside the web, JPG remains the safer default.
Which Should You Choose
For web use — product photos, blog images, thumbnails — WebP usually wins on file size. For universal compatibility, such as printing or sending to someone with older software, stick with JPG.
Converting Between the Two
You don't need to commit to one format ahead of time. Upload your JPGs, pick WebP as the output format, and compress — or go the other direction if a WebP file needs to work somewhere that only accepts JPG.
WebP and Page Speed / SEO
Image weight is one of the biggest factors in Google's Core Web Vitals, particularly Largest Contentful Paint (LCP). Switching hero images and product photos from JPG to WebP is one of the fastest ways to shave meaningful time off a page's load, which can have a real effect on both user experience and search ranking.
Frequently Asked Questions
Does WebP support animation like GIF?
Yes, WebP has an animated mode, but this tool focuses on static photo compression — animated WebP export isn't part of this workflow.
Will old browsers just break if I use WebP?
No major browser released in the last several years lacks WebP support. The only real risk is niche software outside the browser, like some desktop image viewers or older email clients.
What quality setting should I use for WebP?
80-85% is a solid starting point for photos — visually close to lossless with a meaningful size reduction. Drop it to 65-75% for thumbnails or images that are displayed small.
