Image Converter

Convert images between JPG, PNG, and WebP

Every so often a picture is in the wrong format for what you need. A website only accepts JPG, a logo needs a transparent background so it has to be PNG, or you want the smaller WebP files that modern sites prefer. This converter changes an image from one format to another in a couple of taps — drop in your pictures, pick the format you want, and get them back ready to use. It runs entirely in your browser, so the images are never uploaded anywhere.

You can convert one image or a whole batch at once. A single file comes back on its own; several come back together in a ZIP, so changing the format of twenty photos is as quick as changing one.

The three formats, in plain terms

You don't need to be technical to pick the right one — each format is just good at a particular job.

JPG — small files for photos

JPG (also written JPEG) is the everyday format for photographs. It squeezes a photo down to a small file that looks great on screens, which is why cameras and phones use it and why most websites and forms accept it. The trade-off is that it can't store transparency — any see-through areas become solid white — and each save loses a tiny bit of detail. For a normal photo you'd never notice, and the small size is usually worth it.

PNG — quality and transparency

PNG keeps every pixel exactly as it is, with no quality loss, and it supports a transparent background. That makes it the right choice for logos, icons, diagrams, screenshots, and anything with sharp text or lines — or any image that needs to sit on top of another without a white box around it. The files are larger than JPG, so PNG is about quality and transparency rather than small size.

WebP — the modern web format

WebP is a newer format built for the web. It can make files noticeably smaller than JPG or PNG at a similar quality, and it supports transparency too — so it often gives you the best of both. It's ideal when you're building a website or want pages to load faster. The only catch is that a few older programs don't recognise it yet, so if you're sending an image to someone who needs to open it in anything, JPG or PNG is the safer bet.

Which way should I convert?

A few common situations make the choice obvious:

• PNG → JPG when a screenshot or exported graphic is a huge PNG and you just need a small file to email, upload, or attach — and it has no transparency to preserve.
• JPG → PNGwhen you need lossless quality for editing, or you're about to cut out a background and want transparency to be possible.
• Anything → WebPwhen you're putting images on a website and want them light and fast without giving up transparency.
• WebP → JPG or PNGwhen you've downloaded a WebP image and a program or a person you're sending it to can't open that format.

A quality slider lets you lean toward a smaller file or a sharper result when you convert to JPG or WebP. And converting the format isn't the same as shrinking a file — if your goal is purely a smaller image at the same format, the Image Compressor is the better tool. If you need different pixel dimensions, the Image Resizer changes the size — both run in your browser too.

A note about WebP on iPhone

Being honest about a limitation: on an iPhone or iPad, Safari can't save images as WebP. When you're on one of those devices the WebP option is hidden automatically and the tool defaults to PNG, so you always get a working file rather than an error. Reading a WebP image and converting it to JPG or PNG works fine everywhere — it's only creating a WebP that Safari on iOS doesn't support. On a computer with Chrome, Edge, or Firefox, WebP export is available as normal.

Converting a batch at once

Add as many images as you like — they show as thumbnails so you can check what you loaded and remove any you didn't mean to include. Pick one target format and quality, and every image is converted the same way. One image downloads on its own; a batch is bundled into a single ZIP so you're not saving files one by one. It's the quick way to make a folder of mismatched pictures all the same format.

What about iPhone HEIC photos?

Photos taken on a recent iPhone are often saved as HEIC, a format many websites and Windows programs can't open. This converter focuses on JPG, PNG, and WebP; for HEIC specifically there are dedicated tools that decode it properly — HEIC to JPG is the one most people want, turning iPhone photos into universally supported JPGs in your browser.

Privacy: your images never leave your device

The whole conversion happens on your device, right in the browser. Nothing is uploaded, nothing is stored on a server, and there's no account to create. When you close the page the images are gone, because they were never sent anywhere in the first place — which matters when you're converting personal photos or work files.

Frequently asked questions

Which formats can I convert between?

JPG, PNG, and WebP, in any direction — for example PNG to JPG, JPG to PNG, or either of those to WebP. You can bring in other common image types too and convert them to one of these three.

Will transparency be kept?

It depends on the target format. PNG and WebP support transparency, so a see-through background survives. JPG has no transparency, so any transparent area is filled with white when you convert to JPG.

Why can't I choose WebP on my iPhone?

Safari on iPhone and iPad can't create WebP files, so the option is hidden on those devices and PNG is used instead — you still get a working file. WebP export works on a computer with Chrome, Edge, or Firefox.

Are my images uploaded to a server?

No. Everything runs in your browser — the images never leave your device and nothing is stored or sent anywhere.
