JPG to WebP

Shrink JPG photos for your website by converting them to WebP, with the quality and size you choose, all on your device.

Drop JPG images here

Or any JPG, PNG, WebP, AVIF or HEIC, as many as you like. They become WebP files.

Your images are converted on this device and never uploaded. Location and other EXIF data are removed.

How this works

Method

Each image is decoded by the browser itself (HEIC only where the browser opens HEIC, as Safari 17 and later does: the site ships no HEIC decoder, because HEVC is covered by patents), turned upright from its EXIF orientation, resized if asked, and drawn on a canvas in a background worker, over your background colour for JPG. The browser’s own encoder writes JPG, PNG or WebP at your quality (libwebp where it can’t write WebP). Rebuilt from pixels, the file has no EXIF; if you keep metadata, the original EXIF is copied in with orientation reset and, unless you keep all, the GPS block emptied.

How it’s tested

One worked example for this page is checked by automated tests before every release: given the inputs, the tool must show the expected answer.

Changes

  • HEIC now opens only where the browser reads it (Safari 17+), with tips elsewhere; the bundled HEIC decoder was removed because HEVC is covered by patents.
  • First version: HEIC, WebP, AVIF, PNG, JPG, GIF and BMP to JPG, PNG or WebP, in batches with a ZIP, metadata removed by default, and nine conversion pages.

Getting smaller photos for the web

A JPG to WebP conversion recompresses a photo that was already compressed, so the gain depends on how the JPG was saved. A large JPG straight from a camera usually shrinks a lot; a JPG that was already squeezed hard may shrink only a little, and at high quality the WebP can even come out larger. Each row shows the result, so you can see.

Resizing often saves more than the format. A 4,000-pixel-wide phone photo shown in an 800-pixel column carries more than twenty times the pixels it needs. Fit the longest side to about twice the width it is shown at, for sharp screens, and then convert.

Phone photos stored sideways are turned upright first, using their EXIF orientation, and the GPS position and other EXIF data are removed by default, which is what you want for photos on a public website.

In Safari, which can’t write WebP from a canvas, the page loads a small WebP encoder the first time you convert.

Good to know

Open-source code inside, loaded only when needed: JPEGs are encoded with MozJPEG, PNGs packed with OxiPNG and WebP written with libwebp where the browser can’t. Pictures, HEIC included, are decoded by the browser itself. Licences and source

How to convert JPG to WebP3 steps, all on your device
  1. Drop the JPGs. Add the photos for your page: product shots, blog images, a gallery.
  2. Pick quality and size. Quality 80 to 90 suits most photos. Under More options, fit the longest side to the width your site shows, such as 1,600 pixels.
  3. Download the WebPs. Compare the sizes in the list, then save them one by one or as a ZIP.

Frequently Asked Questions

How much smaller is WebP than JPG?

Google measured 25 to 34 percent smaller at the same visual quality. Your results depend on the photo and how the JPG was saved; the list shows each file’s size before and after.

Should I keep the original JPGs?

Yes. Converting a lossy file to another lossy format loses a little detail, so keep the originals and convert again from them if you need another size or quality.

Is location data removed?

Yes, by default. The WebP is written from the pixels with no EXIF, so there is no GPS position, camera model or capture time in it.
