Why switch from JPG to WebP?
WebP is a modern image format from Google that squeezes photos into noticeably smaller files than JPG. In most cases you can expect savings of around 25 to 35 percent at a similar level of visual quality, and the difference is often hard to spot with the naked eye.
Smaller images mean faster pages. They help your Largest Contentful Paint, they use less mobile data, and they clear the “Serve images in next-gen formats” tip you’ve probably seen in PageSpeed Insights. Better page speed is good for visitors, and it’s good for search too.
WebP is also more flexible than JPG. It supports transparency like PNG and it can be lossy or lossless, so one format covers photos, logos and graphics. Every current browser can display it, which makes it a safe default for the web today.
| Format | Best for | Transparency | Compression |
|---|---|---|---|
| JPG | Photos that need to open anywhere | No | Lossy |
| PNG | Logos, screenshots and sharp text | Yes | Lossless |
| WebP | Photos and graphics on websites and in apps | Yes | Lossy or lossless |
Who is this converter for?
Pretty much anyone who works with images.
Website owners and developers
Swap heavy JPGs for WebP and watch your page weight drop without redesigning anything.
Bloggers and online shops
Product photos and cover images load faster on mobile connections, so fewer visitors give up and leave.
Anyone stuck with a WebP file
Some forms, email clients and print services still ask for JPG. Convert your WebP downloads back in a click.
People short on storage
Shrink a folder of photos to a fraction of its size before you archive it or send it to someone.
Tips for the best results
Start at quality 80. Photos look great between 75 and 85. Only go higher if you spot artifacts.
Treat screenshots differently. Sharp text and flat colors can need a quality of 90 or more, or simply stay with PNG.
Resize while you convert. A full-width banner rarely needs to be wider than 1920 px, and the max width option does it for you.
Keep your originals. Every lossy save trims a little more detail, so always convert from the source file when you can.
Check the numbers. The size next to each file shows how much you saved, so you can tweak the quality and compare in seconds.
Frequently asked questions
How do I convert JPG to WebP?
Drop your JPG files into the converter above, keep WebP selected as the output format, and nudge the quality slider if you want to. Each image is converted in a second or two, and you can download them one by one or all together as a ZIP.
Is this JPG to WebP converter really free?
Yes, it’s completely free. There’s no account, no watermark and no daily limit. To keep things smooth on every device we cap a batch at 50 images and 30 MB per image.
Are my images uploaded to a server?
No. The conversion runs entirely inside your browser, so your photos never leave your device. Nothing is stored, logged or shared, and once you install the app it keeps working offline.
Can I convert WebP or PNG to JPG as well?
Absolutely. Add your WebP or PNG files, choose JPG as the output format and download the result. JPG can’t store transparency, so see-through areas are filled with a background color you can pick, white by default.
What quality setting should I use for WebP?
For photos, 75 to 85 is the sweet spot: files get much smaller and most people can’t spot the difference. Go to 90 or higher for images with fine detail or text, and choose PNG when you need a lossless copy.
Do all browsers support WebP?
All current versions of Chrome, Edge, Firefox, Safari and Opera can display WebP, on desktop and mobile. If you need to support very old browsers, keep a JPG copy and serve it as a fallback with the picture element.
Why is my converted file bigger than the original?
It happens when the original was already heavily compressed, or when you convert a JPG to PNG, which is lossless. Lower the quality, pick WebP as the output, or reduce the maximum width and the new file should shrink.
Does the converter keep EXIF data like location and camera info?
No. Images are redrawn during conversion, so metadata such as GPS location and camera details is left out. The photo’s orientation is applied correctly, so it still looks the way it should.
Can I install it as an app?
Yes. Tap the Install app button at the top of the page. On iPhone and iPad open the Share menu in Safari and choose Add to Home Screen. Once installed it opens in its own window and works offline.
Keep the converter one tap away
Install it on your phone or computer and convert images any time, even without a connection.
