When PNG is the better choice
- You will edit the image again. Every time a JPG is saved it loses a little quality. Convert to PNG once, then edit and save as often as you like.
- A form or tool asks for PNG. Some sign-up forms, design tools and app stores only accept PNG.
- The image has text or sharp lines. Charts, diagrams and screenshots stay crisper in PNG once you start editing them.
For photos you just want to share, JPG is usually the better format, because the files are much smaller.
Common mistakes
- Expecting better quality. PNG stops further quality loss, but it cannot bring back detail that was lost when the JPG was made. Start from the best original you have.
- Expecting a transparent background. Converting does not remove the background. The white or coloured background in the JPG stays in the PNG.
- Making a huge file by accident. A 12-megapixel photo as PNG can be over 15 MB. If you do not need full size, set a maximum width such as 1,600 pixels.
Examples
Editing a product photo: convert the JPG to PNG, crop and adjust it in your editor as many times as needed, then export the final version as JPG or WebP for the web.
App or website icons: a design tool asks for a PNG icon. Convert your JPG, then crop it to a square with Crop image.
Adding a picture to a PDF: PNG and JPG both work with Add image to PDF. Use PNG for logos and stamps with sharp edges.
