About JPG to WebP

Convert JPG to WebP when a page feels slow or PageSpeed Insights tells you to serve images in next-gen formats. WebP usually stores a photo in a smaller file than JPG at a similar look, and every current browser displays it. WordPress, Shopify and most site builders accept WebP uploads. Transparent PNGs have a WebP converter of their own, listed in Image Converter.

Quality starts at 90, which keeps photos crisp; try 75 to 85 for pages where every kilobyte counts. Under More options you can resize oversized camera photos to the width your layout actually uses, which is often the biggest saving of all. Turn off Keep photo info (EXIF) to drop camera and location data, which trims the file a little more.

FAQ

JPG to WebP: questions and answers

How much smaller is WebP than JPG?
It varies with the picture and the quality you choose. Photos often come out noticeably smaller at a similar look; compare the sizes after converting and lower Quality a little if you need more.
Will my JPG to WebP images show in every browser?
Yes, in all current versions of Chrome, Safari, Firefox and Edge. Very old browsers such as Internet Explorer don't display WebP, so keep the JPG if you must support them. You can turn a WebP back into a JPG later with WebP to JPG.
Should I convert JPG to WebP at quality 100?
Usually not. At 100 the WebP can end up bigger than the original JPG, because it can't recover detail the JPG already lost. For websites, 75 to 90 gives a good trade-off.
How many JPGs can I convert at once?
One per task on the free plan, with 2 tasks a day and files up to 50 MB. VIP converts up to 50 images per task, with no daily cap and files up to 1 GB.
Are my photos kept after conversion?
No. Uploads are encrypted, each job runs in its own isolated process, and every file is deleted automatically after one hour. We don't share or sell images, or use them to train AI.
