JPG (also written JPEG) is the picture format almost every website, form, printer and app accepts. If you have a picture in another format, such as a PNG screenshot, a WebP from a website or an iPhone HEIC photo, here is how to save it as JPG with the tools you already have.
Before you start, check what you have. If the file already ends in .jpg, .jpeg or .jfif, it is already a JPEG. .jfif files can simply be renamed to .jpg.
On Windows: Paint
Paint is on every Windows PC and opens PNG, BMP, GIF, TIFF and, on current Windows versions, WebP.
- Right-click the picture, choose Open with, then Paint.
- Select File › Save as › JPEG picture.
- Choose a folder and name, then Save.
Paint doesn’t offer a quality setting. If the JPG must be small, compress it afterwards. Transparent areas become white.
For HEIC photos, Windows needs extra extensions from the Microsoft Store before Paint or Photos can open them. Converting in the browser avoids that (see below).
On Mac: Preview
- Open the picture in Preview.
- Choose File › Export.
- Set Format to JPEG and drag the Quality slider. The estimated file size updates as you move it.
- Click Save.
Many pictures at once on Mac
On macOS Monterey and later, Finder can convert a batch without opening anything:
- Select the pictures in Finder.
- Right-click and choose Quick Actions › Convert Image.
- Choose JPEG and an image size, then Convert to JPEG.
On iPhone
iPhones save photos as HEIC and screenshots as PNG. There are several ways to get JPGs: a camera setting, a transfer setting, the Shortcuts app and converting in Safari. They are covered step by step in how to convert iPhone photos to JPG.
On Android
Most Android cameras already save JPG, but screenshots are usually PNG and pictures saved from websites are often WebP. Built-in options vary by phone maker, so the most reliable way is to convert in the browser, which works the same on every Android phone.
In any browser, on any device
xconverter’s converters run in your browser, so they work on Windows, Mac, Chromebook, Android and iPhone with nothing to install. Your pictures are processed on your device and never uploaded.
| Your picture | Converter |
|---|---|
| PNG (screenshots, graphics) | PNG to JPG |
| WebP (saved from websites) | WebP to JPG |
| AVIF (saved from websites) | AVIF to JPG |
| HEIC (iPhone photos) | HEIC to JPG |
You can convert many pictures at once and download them together as a ZIP.
Which JPG quality should you choose?
JPG is a lossy format: a quality setting decides how much fine detail is kept.
- 85% is a good default for photos you share or upload.
- 90–95% for pictures you’ll print or edit further.
- 70–75% when a small file matters most, such as for email or chat.
Avoid saving the same JPG over and over: each save loses a little more detail. Keep your original and make JPGs from it.
What JPG can’t do
- Transparency: JPG has none, so see-through areas become a solid colour, usually white. Keep logos with transparent backgrounds as PNG.
- Sharp text: screenshots full of small text look slightly smudged as JPG. PNG keeps them crisp.
- Animation: an animated GIF or WebP becomes a single still frame.
Saving pictures from websites
When you right-click a picture on a website and choose Save image as, you often get a WebP or AVIF file instead of a JPG. That is because websites send modern formats to browsers that support them. Why images download as WebP explains what is going on, and how to get a JPG or PNG instead.
