How to convert images online

  1. Choose one or more images in any common format.
  2. Pick JPG, PNG or WebP as the output.
  3. Download each converted file, or all of them as a ZIP.

Formats this image converter supports

This image converter opens JPG, PNG, WebP, GIF and BMP files. Other formats work if your browser can open them; for example, Safari can read HEIC photos from an iPhone. For an animated GIF, only the first frame is converted.

You can save as JPG, PNG or WebP. For JPG and WebP, a quality slider (90 by default) lets you trade file size for detail. PNG keeps every pixel, so it has no quality setting.

Choosing the right format

When an image with a transparent background is saved as JPG, the clear parts are filled with a color. White is the default, and you can pick another color in the tool. If you need a website icon in the .ico format, use PNG to ICO.

Frequently asked questions

How do I change a picture to JPG?

Choose the picture, keep JPG as the output, and download the new file. It works the same way on a phone or a computer.

Which format makes the smallest file?

For photos, WebP is usually the smallest, followed by JPG. PNG is normally the largest for photos, but it suits sharp graphics and screenshots. If you need a file under a set size, use the compress tool instead.

Does converting reduce image quality?

Converting to PNG keeps every pixel as it is. Converting to JPG or WebP removes a little detail to save space. At the default quality of 90, this is hard to see.

Can I convert HEIC photos?

Only if your browser can open them. Safari on iPhone, iPad and Mac usually can. In other browsers, a HEIC file may show an error saying it cannot be opened.

Are my images uploaded for conversion?

No. Your browser does the conversion, so your images never leave your device. Nothing is sent to our server or to any other service.
