JPG to WebP Converter
Make lighter images for your website: convert JPG photos to WebP, compare the file sizes, and download them all at once.
Nothing is uploaded. Your photos are converted inside your own browser and never leave your device. No signup, no watermark, no limit on the number of files.
Higher keeps more detail and makes bigger files. 90% suits most photos.

Good to know
- Phone photos stay the right way up: the rotation stored in the file is applied before converting.
- JPG has no transparency, so converting to JPG fills transparent areas with white. PNG and WebP keep transparency.
- Converting re-encodes the picture, so camera metadata (EXIF: date, camera settings, GPS location) is not copied to the new file. That also means a converted photo no longer reveals where it was taken. To see what a photo carries first, open it in the EXIF viewer.
- Large photos, 48 MP and up, take a few seconds each. If a browser cannot hold one at full size, it is saved at the largest size that browser allows and labelled so in the list.
Why websites use WebP
WebP was designed for the web. Google’s comparison found lossy WebP files 25 to 34% smaller than JPGs of the same quality, and smaller images mean faster pages, which visitors notice and search engines measure. Every current browser displays WebP, including Safari since version 14.
When to convert JPG to WebP
Convert the photos you publish: portfolio and gallery images, blog photos, product shots in a shop. Keep your JPG originals for everything else. Print labs, clients and many editing tools still expect JPG, and a WebP made from a JPG is a second lossy copy, not a master.
Choosing the quality
Start at 80 to 90% and compare: the list shows each file’s size before and after. Fine textures such as hair, fabric and foliage show compression first, so check those at 100%. Camera metadata, including copyright fields, is not copied to the WebP; that keeps location data off your website, but add credits on the page if you need them.

Frequently asked questions
Do all browsers support WebP?
All current versions of Chrome, Edge, Firefox and Safari display WebP. Safari has done so since version 14 in 2020. Saving WebP is a different matter: this converter needs a browser that can encode it, such as Chrome, Edge or Firefox.
How much smaller will my images be?
It depends on the photo and the quality you choose. Google measured 25 to 34% at equal quality; the list on this page shows the real before and after size of each of your files.
What quality should I use for a website?
Around 80% suits most web photos. Use 90% for portfolio images where detail matters, and check fine textures at full size before you publish.
Should I delete the original JPGs?
No. Keep the JPGs as your originals for printing, client delivery and future edits. The WebP files are copies made for the web.
