Convert JPG to WebP

WebP usually produces a noticeably smaller file than JPG at the same visual quality, which makes it a good choice for images on a website. Do not use it for application forms — most will not accept it.

Your file stays on your device. This tool runs entirely in your browser — nothing is uploaded to our servers, and nothing is stored.

How to convert JPG to WebP

  1. Choose your JPG file.
  2. Set the quality. 75–85% suits most web images.
  3. Convert and compare the sizes shown.
  4. Download the WebP.

Supported formats

JPG / JPEG, PNG in. WebP out.

Important limitations

Worth knowing before you start, so nothing here comes as a surprise at the point you are submitting a form:

  • Most government and university application forms do not accept WebP. Convert to WebP for websites, not for uploads.
  • A few older browsers and desktop applications still cannot open WebP files.
  • Converting a JPG to WebP re-compresses an already-compressed image. Start from the original where possible.

How your files are handled

This tool does its work using your browser’s own image and document engine. Your file is read from your device into the page’s memory, processed there, and offered back to you as a download. It is never sent to Fyleit, never written to a server, and never stored anywhere we can reach.

You can verify that for yourself: load this page, disconnect from the internet, and the tool still works. That is also why there is no sign-up and no email field — we have nothing to attach an account to.

Common problems

My browser could not save as WebP.

A small number of older browsers cannot encode WebP. The tool detects this and says so rather than quietly handing you a PNG with the wrong extension. Try a recent version of Chrome, Edge or Firefox.

Frequently asked questions

Are my photos uploaded to a server?
No. This tool uses your browser’s own image engine, so the photo is read, processed and saved entirely on your device. Nothing is sent to us, and nothing is stored. You can confirm this by opening your browser’s network tab, or by disconnecting from the internet after the page has loaded — the tool keeps working.
How much smaller is WebP?
Typically 25 to 35 percent smaller than JPG at comparable quality, though it varies a lot with the image. The tool shows both sizes so you can judge for yourself.
