About the JPG to WebP Converter
The photo you're about to drag into a free online converter probably has your home address sitting inside it. Phones stamp the GPS coordinates, the camera model, sometimes a serial number, straight into the JPG file. Upload that to a server-based converter and you've handed a stranger both the picture and the spot it was taken. Neither of those things can happen on this page. Your file never leaves your browser, and the location and camera metadata gets wiped automatically as it converts.
And yes, it does the thing you actually came for. Drop in one JPG or a couple hundred at once, and each one comes back as a WebP that holds the same photo in noticeably fewer bytes. Download them one at a time, or grab the whole batch as a single ZIP. Nothing uploaded, no daily cap, no account, no watermark stamped across your work.
How to use
- Drop your JPGs onto the box, click to browse, or paste one straight from your clipboard. One file or two hundred, it takes them all at once.
- Set the quality if you care to. 80 is the default and it's the right call for almost any web photo. Nudge it toward 100 for a hero image you want pristine, or down toward 70 for small thumbnails nobody looks at closely.
- Got a sideways phone shot? The rotate and flip buttons straighten it out on the way through, applied to every file in the batch, so you skip a separate editor.
- Hit Convert. Every file is processed right on your device, in parallel, so a big batch doesn't crawl.
- Download each WebP on its own, or use Download all (ZIP) when you converted a batch. The results panel shows you the before and after size on every file and the total percentage you saved.
The metadata your JPG is quietly carrying
Every photo your phone takes comes with a block of extra data baked into the file, called EXIF. For anything shot outdoors that usually includes the exact GPS coordinates of where you were standing, down to a few meters, plus the camera or phone model and the timestamp. It's invisible when you open the image, it goes along for the ride anyway every time you send the file somewhere.
That's a real problem the moment a photo goes public. It's how a casual snap gives away where your kids go to school or where you live. And it matters just as much for work you'd never think of as sensitive, product shots taken in a home studio, real estate photos, anything where the exact location is nobody's business but yours.
Most free converters do nothing about this. Worse, plenty of them upload your original to their server to do the conversion, so now the file AND its location tag are sitting on a machine you don't control. Ours strips the EXIF block as part of the conversion, automatically, on every single file, so the GPS and the camera details are gone from the copy you download. And because the whole job runs in your browser, the file never travels anywhere to get converted in the first place. You can prove that to yourself in about ten seconds, though not with the wifi switch. It does not work offline from a cold start, because the WebP encoder ships as two builds of 345,584 and 281,261 bytes, your browser takes whichever one it can run, and it only comes down on your first press of Convert. Open the network panel instead and convert something. You will see that request and a 166,470-byte JPEG reader go out, and you will not see your photo.
Picking a quality you won't second-guess
Both JPG and WebP throw away some data to stay small, so converting one to the other runs your photo through compression a second time, which at sensible settings you will never see. At 80, a WebP looks like the same photo to your eye at a fraction of the size, which is exactly why it's the default here.
Quality matters less than you'd think. What really decides the result is the source image. If your JPG was already saved rough and blocky, WebP can't undo that. Those artifacts are permanent, so all you get is a smaller copy of a rough image. A clean, decent original converts beautifully. Feed it something already battered and you just get a lighter version of the same mess.
One habit worth dropping: don't bounce a photo back and forth between JPG and WebP over and over. Each round trip shaves off a little more quality, and it stacks up fast. Convert it once, to the format you're actually going to serve, and leave it there. If you still have the untouched original from your camera or a design file, convert from that instead of from a JPG that's already been squeezed once.
How much smaller, really
Google built WebP specifically to beat JPG on size, and for photographs it does, usually somewhere around a quarter to a third smaller at the same visible quality. A 500 KB product shot often lands near 350 KB with no difference you can see. On a page stuffed with images that adds up quickly, and it's often what stops a heavy gallery from loading so slowly that people give up on it before it finishes. It's also a direct lift for your Core Web Vitals and Lighthouse scores, since images are usually the heaviest thing a page has to pull down. Re-encode your hero images and photo galleries as WebP and the Largest Contentful Paint number improves on its own.
Frequently asked questions
Why did my WebP come out bigger than the JPG?
Usually because the source was already a small, heavily optimized JPG with little left to save, or because you set the quality near 100. WebP wins big on ordinary camera photos, but a tiny already-compressed file has almost no fat left to trim, and pushing quality to the top can tip it over the original size. Drop the quality back to 80 and it'll come out smaller in nearly every case.
Does this take only JPG, or other formats too?
This page is set up for JPG in, WebP out, which keeps it simple for the most common job. If you've got PNGs, HEIC files off an iPhone, or a mix of things, use our general image converter instead. It accepts any format and lets you pick whatever output you want.
Will stripping the EXIF leave my phone photos sideways?
No, though it's a fair thing to check, because plenty of converters do leave them sideways. A lot of phone photos are actually stored on their side, with a hidden flag telling the viewer to spin them upright when it shows them, and once the EXIF block goes that flag goes with it. So this tool reads the flag off the JPG first and writes the rotation into the pixels, before the WebP encoder ever sees them. What comes back matches what you saw on the phone, and every app agrees on it, because nothing is left hanging on a flag that only some programs bother to read. The rotate button is there for a shot that genuinely was taken the wrong way up.
Will a WebP open in email and older apps?
Every current browser reads WebP, which covers well over 95 percent of people online. The gaps are old desktop software and some email clients. If a specific photo is headed into a newsletter or a dated program, keep a JPG copy for that one, or serve both with an HTML picture tag so each device grabs the format it can actually open.
Is there a limit on how many I can convert?
No cap on the files you pass in yourself, and no per-file size wall. One image or a few thousand, it's all the same to the tool. Because your own device does the work, a large batch just uses your processor instead of waiting in a queue behind other people's uploads. Drag a whole folder instead and one number turns up, since the walk stops at the first 3,000 images and the tool tells you on screen that it did, so the remainder goes in on a second drop. An older phone will take a bit longer on a big run, and that's about the only other thing slowing you down.
Does converting actually strip the location data?
Yes. The EXIF block that holds the GPS coordinates, camera model, and timestamp is dropped from every WebP as it's created. If you want to confirm it, right-click the finished file and open its properties or details, and the location fields will be blank. Worth doing once so you trust what it's doing on the rest.
