What is a JPG file?
The JPG (or JPEG) format is one of the oldest and most recognizable, with universal compatibility across all devices and operating systems; whether it’s made by Apple, Windows, Linux, or any manufacturer, or any software you can think of, it most likely supports JPG. It was developed in 1992 by the Joint Photographic Experts Group (yup, JPEG), and that’s where it got its name.
For the past 30 years or so, JPG has been the default format for smartphones, cameras, and nearly every device that processes images. I’ve owned digital cameras from Sony and Canon, and they default to JPG when you export photos. Its biggest strength is its compatibility across almost every device you can think of.
However, JPG’s biggest downside is that it uses lossy compression, meaning that to keep file sizes from ballooning, it throws away small bits of color and detail every time you save it at a lower quality. You won’t notice it in a high-resolution photo from a digital camera, but if you resize the photo or save it at an extremely low quality, you’ll see pixelated areas that show up as block artifacts around sharp edges, text, or solid color areas. And this compounds every time you save the file.
JPG is best suited for:
- Photographs with lots of color and gradients
- Sharing images on social media, email, or text
- Uploading photographs to websites
- Sending images to photo studios for printing
JPG isn’t good for:
- Logos, screenshots, or anything that requires sharp lines or text
- Images that may need a transparent background
- Source files you plan to edit again and again
- Any image that requires high resolution for printing in a larger format
What is a PNG file?
The PNG (or Portable Network Graphics) was released in 1996 as a free replacement for the older GIF format. Unlike JPG files, PNG uses lossless compression, meaning you can shrink a file without degrading pixel quality. So you can save these images repeatedly without losing any visual quality.
The lossless nature of PNG is what makes it an ideal option for images that require sharp edges like logos, screenshots, UI mockups, line art, or diagrams. Also, this format supports a full alpha channel, meaning you can save images with a transparent background, like icons or logos. PNG is one of the formats designers and developers prefer when they need an image that can sit above any background.
However, PNG’s downside is its file size. Typically, a comparable PNG file is around three to five times larger than the same JPG photo because PNG doesn’t discard any data. If you’re uploading a photograph on Instagram, that can be wasted bytes, but for a logo on your website, it can be an alternative, but newer formats like WebP and AVIF offer better compression for users who need max compression for transparent logos on websites.
PNG is best suited for:
- Logos, icons, and UI interface mockups
- Screenshots and software documentation
- Images that require a transparent background
- Diagrams, charts, and line art
- Any image you plan to edit repeatedly without losing quality
PNG isn’t great for:
- Large photographs (landscape, people, etc.) where file size matters
- Email attachments or batch uploads over slow connections
- Situations where the receiver’s device may not render transparency correctly
Why convert JPG to PNG?
You’d want to convert a JPG to a PNG format because of two things: better quality or the need for a transparent background.
For example, if you need to edit a JPG file, you could crop it, add text, or retouch it; every re-save chips away at the quality. Converting that JPG file to PNG locks the quality in place, so every edit done afterward will be lossless. If you’ve saved an already edited JPG, you won’t recover those lost pixels, but you won’t lose any more either.
The second reason is transparency. JPG files don’t support transparency. If you try to save it, a background will be added no matter what you do. If that is a requirement, PNG is one format that supports images with a transparent background. It’s also a safer option if you’re handing over an image to a graphic designer or sending images to a print shop — basically anything that requires a high-resolution version of the image.
Frequently asked questions
Nope, files aren’t uploaded, and everything runs in your browser using WebAssembly.
Two reasons I’ve talked about earlier: quality and transparency support. PNG files are lossless by default, so even when you save them again and again, the quality will not degrade because re-encoding doesn't reduce quality, and they support images with transparent backgrounds, like logos and icons.
No, not automatically. JPG files don’t support transparency, and converting them to PNG won't create any, so the resulting PNG will be opaque. The only way to create transparency is to use a tool like GIMP or an online background remover. If your image has a solid background, you could use our background remover tool to remove the background and save it in a format that supports transparency.
Unfortunately, it doesn’t, but it will stop any further lossy degradation from lost pixels when you re-save it. If your JPG file has compression artifacts (meaning degraded pixels from previous saves), the resulting PNG file will have those same artifacts, but preserved in a lossless format.
If you’re talking about photographs, PNG files are typically three to five times larger than an equivalent JPG photograph. That’s because PNG’s lossless compression is less efficient in terms of keeping file sizes low, so it’s a trade-off that you need to consider. You could opt to convert to other formats like WebP or AVIF if image size is a top priority and you need to upload to a website. These formats support transparency, but are more efficient at encoding pixels and keeping file size down.
