Convert JPG to WEBP for faster pages and smaller uploads. At the same visual quality WEBP is about 30% smaller than JPG.
What is JPG to WEBP?
Our jpg to webp converter re-saves JPG photos as WEBP, the web format that delivers the same visual quality in a noticeably smaller file. On average WEBP is about 25–34% smaller than an equivalent JPG, so pages load faster, image-heavy galleries feel snappier and you use less hosting bandwidth.
Pick a quality, drop in one image or a whole folder, and download the WEBP versions individually or as a ZIP. Conversion runs in your browser with its built-in encoder, so your photos stay on your device, with no watermark added.
How to convert JPG to WEBP
- Drop JPG files.
- Set quality: 80% matches a 90% JPG visually.
- Download WEBP files or a ZIP.
How JPG to WEBP works
JPG and lossy WEBP both throw away detail you are unlikely to notice, but they do it differently. JPG works on fixed 8×8 blocks independently. WEBP, derived from the VP8 video codec, first predicts each block from pixels already decoded above and to the left, then stores only the difference, and finishes with a smarter entropy coder. Less information to store means fewer bytes.
Because the two use different scales, quality numbers do not match one to one. A WEBP at 80% looks roughly like a JPG at 90%. Converting one lossy format to another does lose a little extra detail, so always start from the highest quality JPG you have rather than an already compressed copy.
Here your browser decodes the JPG, applies its rotation tag so the picture is upright, and encodes WEBP at your chosen quality on a canvas. Nothing leaves your device, and the camera's EXIF and GPS data are not copied into the new file.
Key features of JPG to WEBP
Free, a whole gallery per run
Convert a single hero image or an entire gallery without paying or accepting watermarks. Batch conversion and ZIP download are part of the free tool, not a paid extra.
Same look, smaller files
At 80% WEBP quality, photos look like a 90% JPG while weighing roughly a quarter to a third less. The slider runs from 40% to 100%, and pixel dimensions stay exactly the same.
Fast, on-device encoding
Your photos never travel to a server, and there is no queue. Your browser's WEBP encoder handles each photo in a second or two on most devices, and batches run one after another without waiting.
Runs on desktop and mobile
Convert in Chrome, Edge, Firefox or Safari on Windows, macOS, Linux, Android, iPhone and iPad. Photos straight from a phone gallery work as well as files from a laptop. No install is needed.
Easy for every user
Use the keyboard for every control, rely on clear labels for screen readers and hear progress announced as files finish. Dark mode, browser zoom and small screens are supported, with no time limits.
Photos stay on your device
Family pictures and unpublished client shoots are processed inside your browser tab and never stored elsewhere. Location data from the original JPG is not carried into the WEBP. You can confirm this in the network tab.
What makes EZCompressor's JPG to WEBP different
Real quality numbers
You set the actual encoder quality instead of choosing from vague presets, so you can match settings across a whole site and get predictable file sizes every time you convert.
Location data removed
The WEBP is written without EXIF, so GPS coordinates and camera details from your phone are not published along with the photo when it goes up on your website. Your privacy stays protected.
No plugin or CLI
Converting to WEBP usually means a CMS plugin or a command-line encoder. This tab does the same job for a folder of photos and gives you a ZIP to upload.
Why use JPG to WEBP?
Convert JPG to WEBP to speed up your website. Photos are usually the heaviest part of a page, and trimming a quarter or more from each one improves load times, mobile experience and the image recommendations in page speed reports. Blogs, portfolios and online stores benefit most.
Change JPEG to WEBP for the web, but keep JPG where compatibility counts: email newsletters, print services and some older apps still prefer it. Hold on to your original JPGs, convert copies for the site, and you have the best of both.
Who can use JPG to WEBP?
Bloggers
Convert post images to WEBP before uploading, so long articles with many photos load quickly on phones and score better in page speed tests.
Photographers with portfolios
Serve lighter gallery images on your site while keeping full-quality JPG masters for clients and print orders. Your originals are never altered.
Online store owners
Shrink product photo catalogues to WEBP and cut page weight on category pages where dozens of images load at once.
Agencies and freelancers
Optimise a client's photo library before launch without installing plugins on their CMS or uploading their images to another service.
Travel and food writers
Image-heavy guides and recipes load faster when every photo is WEBP, keeping readers scrolling instead of waiting. It also saves hosting bandwidth.
Settings explained
| Setting | What it does |
|---|---|
| Quality | Higher keeps more detail but makes a larger file. 80–90% is visually identical to the original for most photos. |
| Background for transparency | Colour used where the source had transparency, since this output format cannot store it. |
