1When Should You Convert JPG to PNG?
While JPG is excellent for photographs and web images due to its small file size, there are many situations where PNG is the superior choice. PNG (Portable Network Graphics) uses lossless compression, meaning every pixel of your original image is preserved with zero quality degradation. If you need to know how to convert JPG to PNG, this guide covers every approach available in 2026.
Common reasons to change a JPG to a PNG include needing transparent backgrounds for logos and graphics, preserving sharp text and line art without compression artifacts, preparing images for print where lossless quality matters, or creating assets for design projects that require pixel-perfect accuracy.
2JPG vs PNG: Key Differences to Consider
- Compression: JPG uses lossy compression (some data is discarded). PNG uses lossless compression (all data is preserved). When you convert JPG to PNG, you cannot recover the quality already lost by JPG compression, but the PNG will not degrade further.
- Transparency: PNG supports alpha channels for transparent backgrounds. JPG does not — every pixel in a JPG has a solid color.
- File size: PNG files are significantly larger than JPG files for the same image content. A 200KB JPG might become a 1.5MB PNG. This is the trade-off for lossless quality.
- Text and graphics: PNG handles sharp edges, text, and flat-color graphics much better than JPG, which can produce visible artifacts around high-contrast edges.

4Method 2: Change JPG to PNG on Windows
Windows users can convert JPG to PNG using the built-in Paint application:
- Right-click your JPG file and choose Open with > Paint.
- In Paint, go to File > Save As.
- Change the "Save as type" to PNG (*.png).
- Name your file and click Save.
You can also use the Photos app on Windows 11: open the image, click the three-dot menu, select "Resize," and then save in a different format.
5Method 3: Convert JPG to PNG on Mac
macOS makes it straightforward to change image formats using the Preview app:
- Open your JPG file with Preview (double-click by default).
- Go to File > Export.
- Set the Format dropdown to PNG.
- Click Save.
Preview also lets you adjust resolution and other settings before exporting, giving you fine-grained control over the output.
6Method 4: Convert JPG to PNG on Mobile
iPhone and iPad
iOS does not natively support converting image formats. The easiest solution is to open our online JPG to PNG converter in Safari. Upload your photo, convert it, and save the resulting PNG to your device.
Android
Many Android gallery apps and file managers include format conversion. Alternatively, use our online converter for a consistent, reliable experience regardless of your Android version or device manufacturer.
7Adding Transparency When Converting JPG to PNG
One of the main reasons people convert JPG to PNG is to add a transparent background. While the conversion itself does not add transparency, you can combine the conversion with background removal:
- First, convert your JPG to PNG using our online tool.
- Then, use a background removal tool or image editor to make specific areas transparent.
- Save the result as a PNG to preserve the transparency.
This workflow is essential for creating logos, product cutouts, and overlays for websites and presentations.
8What Happens to Quality When You Convert JPG to PNG?
An important distinction: converting JPG to PNG does not improve the visual quality of an already-compressed JPG image. The quality loss from JPG compression is permanent. What PNG does is prevent any further quality loss. If you plan to edit an image multiple times, converting to PNG first ensures that each edit cycle does not compound compression artifacts.
9Tips for Best Results
- Use PNG for images with text, logos, line art, and screenshots — these benefit most from lossless compression.
- Be aware that PNG files are larger — if file size is a concern, consider using WebP instead, which offers both lossless and lossy modes.
- For web use, balance quality and file size: convert to PNG only when transparency or pixel-perfect sharpness is required.
- Keep original JPG files as backups before converting, especially for important photographs.
