1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsFor an existing PNG, the simplest Windows 11 option is Paint: open the image, choose Save as, select JPEG, and save a new copy. The other routes are for specific cases—an image inside an Office document, an on-screen capture, or editing in Paint.NET—rather than five equivalent built-in converters. Keep the PNG if you need its transparency or original lossless image data.
Choose the method that fits your image
| Method | Best for | New install? | What it exports |
|---|---|---|---|
| Paint | An existing PNG file | No | A JPEG copy using Paint’s save-format choice |
| Paint with a background decision | A PNG with transparent areas | No | A JPEG copy; transparent pixels cannot remain transparent |
| Office: Save as Picture | A graphic embedded in Word, PowerPoint, or Excel | No, if Office is already available | The selected graphic as JPEG |
| Snipping Tool and Paint | A screenshot or visible on-screen content | No | A captured image saved as JPEG in Paint |
| Paint.NET | Someone already using it or needing more editing tools | Yes, unless already installed | A JPEG file; the app also supports PNG |
Microsoft says Paint can save images in formats including JPEG and PNG. Its save dialog labels can vary with app updates. Microsoft’s Paint guide describes choosing a format when saving.

1. Convert an existing PNG in Paint
- In File Explorer, right-click the PNG and choose Open with > Paint. If Paint is not listed, open Paint from Start and use File > Open to browse to the image.
- In Paint, choose File > Save as, then select JPEG picture or the JPEG option shown in your version.
- Choose a destination and enter a new filename. Check that the format is JPEG, then select Save.
This saves a JPEG copy and leaves the original PNG available. Selecting JPEG in the save or export format menu matters: changing only the filename extension from .png to .jpg does not convert the image data. Microsoft lists PNG and JPEG as separate image formats and extensions. See Microsoft’s list of file formats supported by Windows.

JPEG does not preserve transparent pixels. If the PNG is a logo, icon, or cutout with transparent areas, decide what should appear behind it before saving as JPEG. In Paint, add or choose a background as needed, then use Save as > JPEG picture and save a separate file. Do not assume the app’s default background will be the color you want; inspect the image before saving.

Microsoft describes PNG as a format that can support transparency and JPEG as suited to pictures with many colors. If transparency or the PNG’s original lossless data matters, retain the PNG rather than treating the JPEG as a replacement. Microsoft’s picture-format guidance explains the formats’ different uses.
3. Export a graphic embedded in Word, PowerPoint, or Excel
Use this route when the item you need is an illustration or picture inside an Office document—not as a general converter for any PNG on your computer.

- In Word, PowerPoint, or Excel, right-click the embedded graphic.
- Choose Save as Picture.
- In the save dialog, select JPEG as the file type, choose a destination and filename, then save.
Microsoft documents this command for saving an illustration from an Office document and lists JPEG and PNG among the available formats. Read Microsoft’s instructions for saving a picture or graphic as a separate file.
4. Save a screenshot as JPEG with Snipping Tool and Paint
Use this only when you want a screenshot or an image as it appears on screen. It captures screen content; it is not the right way to convert an existing PNG when you need to preserve its original pixel data.

- Open Snipping Tool from Start and capture the visible area you need.
- Open the captured snip in Paint using the Paint editing option in Snipping Tool.
- In Paint, choose File > Save as > JPEG picture, select a destination and filename, and save.
The exact Snipping Tool controls may differ between versions. Microsoft’s guidance covers saving a snip and opening it in Paint. See Microsoft’s Snipping Tool instructions.

Paint.NET is an optional third-party editor, not a requirement for a straightforward conversion. Its documentation lists JPEG and PNG support and compatibility with Windows 10 and Windows 11. If you already use it, open the PNG and use the app’s save or export format choice to create a JPEG copy; the precise interface can vary by version. Paint.NET’s documentation provides its current format and application information.

For a one-off conversion, Paint avoids installing another application. The available documentation does not establish a particular online converter’s current privacy or handling practices, so this guide does not recommend uploading personal images to an unverified service.

Why Photos is not listed as a conversion method
Microsoft documents that Photos supports JPEG and PNG and includes image-editing features, but the cited guidance does not describe a workflow for exporting an arbitrary PNG as a user-selected JPEG. Opening both formats is not by itself proof that Photos can convert between them. Microsoft’s Photos editing guidance describes its editing features.
