How to Convert to WebP

  1. Add your images - Drag and drop JPG or PNG files. Batch convert multiple files at once.
  2. Set quality - Lower values = smaller files. 80 to 85% is ideal for web use.
  3. Convert & Download - Click convert, then download each file.

This One Runs in the Opposite Direction

Every other converter on this page's shelf exists to escape WebP; this one exists to adopt it, and the audience is different: people with a website. Image weight is usually the largest share of a page's download, it feeds directly into loading speed and Core Web Vitals, and converting your images to WebP is the cheapest large win available, no code changes, no plugins, just smaller files doing the same job.

Typical Savings, By Image Type

The pattern to notice: photos improve meaningfully, but graphics and screenshots converted from PNG are where WebP is spectacular, routinely cutting 60 to 80 percent while keeping transparency. If your site is full of PNG interface shots, this conversion pays for itself immediately.

A Format for Your Site, Not Your Outbox

One limit to know: WebP's universal support only applies to web browsers. Outside them, in email clients, older desktop software, and upload forms with strict whitelists, the walls that send people to our WebP-to-JPG tool still stand. So the working rule is simple: WebP for everything your website serves, JPG or PNG for everything you hand to other people, and keep your original files as masters either way.

Choosing a Quality Setting

The slider starts at 85, which keeps photos visually identical to the originals at normal viewing size. Hero images where every kilobyte counts can usually drop to 75 and still look clean. Screenshots and graphics with small text are the exception: lossy compression softens sharp letter edges, so keep those at 90 or above and compare against the original before swapping it in. If a converted file comes out bigger than its source, which can happen with images that were already compressed hard, keep the original instead.

Putting the converted files to use is usually simple. WordPress has accepted WebP uploads since version 5.8, and many site builders take them too, so upload the converted images and point your pages at them in place of the old JPG and PNG files.

Frequently Asked Questions

Is WebP safe to use on my website now? Yes, the compatibility question is settled: every current browser on every platform has displayed WebP for years, including Safari on Mac and iPhone. The hedging advice from the format's early days no longer applies to websites. Where caution still applies is off the web, in emails and uploads to other systems.
How much smaller will my images get? JPGs typically shrink 25 to 35 percent at matching visual quality. PNGs of graphics and screenshots often shrink far more, sometimes 60 to 80 percent, because WebP handles that content with modern techniques PNG predates. Photos already compressed very aggressively have less left to give.
Can I convert a whole batch at once? Yes. Add as many JPG and PNG files as you like and click Convert All. Each file gets its own download button along with how much smaller, or occasionally larger, it came out, so you can skip any image that did not benefit.
Does WebP keep transparency from my PNGs? Yes, alpha transparency converts intact, which is one of WebP's best tricks: PNG-style cut-out graphics at a fraction of PNG's size. Logos and UI elements are often the biggest single wins from this conversion.
Should I delete my originals after converting? Keep them. WebP output here is lossy, so the originals remain your masters for future edits or re-exports. Convert copies for the website, archive the sources, and you get the speed without burning bridges.
When is WebP the wrong choice? Email newsletters, where several clients still mishandle it; files you will send to other people, who may hit the compatibility walls; and anything uploaded to systems that whitelist JPG and PNG. WebP is a website format first, and it is superb at exactly that job.
