If you have ever downloaded an image and needed it in a different format, you already know the struggle. JPG and PNG are the two most popular image formats on the internet — and knowing how to convert between them is something every phone user, designer, and content creator needs at some point.
This guide covers everything. How to convert JPG to PNG, how to change PNG to JPG, which format is better for different uses, and how to do it on Windows, Mac, iPhone, Android, and online. No tech background needed.
What Is JPG and What Is PNG?
Before getting into the conversion steps, it helps to understand what these two formats actually are and why they exist.
JPG (JPEG) stands for Joint Photographic Experts Group. It is the most widely used image format in the world. JPG uses lossy compression, which means it reduces the file size by permanently removing some image data. The tradeoff is smaller files at the cost of some quality. Every time you save a JPG, it loses a tiny bit more quality.
PNG stands for Portable Network Graphics. PNG uses lossless compression, so no data is thrown away. The image stays sharp and clean no matter how many times you save it. PNG also supports transparent backgrounds, which JPG does not.
According to the World Wide Web Consortium (W3C), PNG was designed specifically as an improved, non-patented replacement for older lossless formats.
JPG vs PNG — Quick Comparison
| Feature | JPG | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | Not supported | Supported |
| File Size | Smaller | Larger |
| Quality Loss | Yes (each save) | No |
| Best For | Photos, social media | Logos, icons, graphics |
| Print Quality | Acceptable | Better |
| Web Speed | Faster loading | Slower (larger files) |
| Editing | Degrades over time | Stays sharp |
When Should You Convert JPG to PNG?
There are several good reasons to convert a JPG to PNG:
- You need a transparent background on the image
- You are going to edit the image multiple times and do not want quality loss
- You are designing a logo, watermark, or icon
- You need sharper output for printing
- You want a lossless version to work with in your design tool
One thing to keep in mind — does converting JPG to PNG improve quality? No. PNG will preserve whatever quality the JPG already has, but it cannot recover data that JPG already threw away. The image will not look better after conversion, but it will not get worse from that point forward either.
You can convert your JPG to PNG right now using Image Converter Tools’s JPG to PNG — free, no sign-up, works in your browser.
When Should You Convert PNG to JPG?
Going the other direction also makes sense in many situations:
- PNG files are large and slow down website loading speed
- You need a smaller file for email or uploading to a platform with size limits
- The image does not have a transparent background, so PNG size is wasted
- The platform or app only accepts JPG uploads
- You want to compress a screenshot or photo before sharing it
According to Google’s Web Performance guidelines, using the right image format can significantly reduce page load time, which directly affects user experience and search rankings. For photographs, JPG is almost always the right choice.

How to Convert PNG to JPG Without Losing Quality
This is one of the most searched questions — and the honest answer is that some quality loss always happens when converting PNG to JPG because JPG is a lossy format. But you can keep the loss very small by doing the following:
- Use a high quality setting when converting (90% or above)
- Convert only once — every extra JPG save loses a little more quality
- Start with a high-resolution PNG
- Use a reliable converter that does not over-compress the output
If quality loss is a major concern and you do not need a smaller file, consider keeping the image in PNG. But for most practical uses like web publishing and social media, the quality difference at high settings is barely noticeable.
According to Mozilla’s image format documentation, JPEG quality settings above 85% are generally considered visually lossless for most practical purposes.
How to Convert JPG to PNG on Canva
If you work in Canva and need to export in a specific format:
- Open your design in Canva
- Click the Share button at the top right
- Select Download
- Click the File type dropdown
- Choose PNG or JPG
- Click Download
If your design has a transparent background, you must export as PNG. Exporting as JPG will add a white background and remove all transparency. For making background transparent again you will need a background remover tool and canva offers it in only piad plans, for this you can use our free and unlimited Background Remover Tool.
Is It Better to Use PNG or JPG?
The answer depends on what you are doing with the image.
Use JPG when:
- The image is a photograph
- You are uploading to social media
- File size and loading speed matter
- The image does not need a transparent background
Use PNG when:
- The image has a transparent background
- It contains text, sharp lines, or a logo
- You plan to edit it multiple times
- You need the sharpest possible print output
A common question is whether it is better to post PNG or JPG on Instagram. JPG is the better choice for Instagram. The platform recompresses all uploaded images, and JPG handles this much better than PNG. PNG files often look worse after Instagram’s recompression.
For web use, you might also want to consider WebP, which gives better quality at smaller file sizes than both JPG and PNG. Our JPG to WebP converter and PNG to WebP converter make it easy to switch.

9. What is the difference between JPG and JPEG?
There is no difference at all. JPG and JPEG are the same format. JPEG stands for Joint Photographic Experts Group. Windows used the shorter .jpg extension historically because early versions only allowed three-letter file extensions, and the shorter version became standard.
10. When should I use PNG instead of JPG for printing?
Use PNG for printing when you need sharp edges, text, or a logo in your printed output. PNG’s lossless compression keeps details crisp. JPG is acceptable for photo prints but PNG gives noticeably better results for graphics and text-heavy designs.
