JPG vs PNG vs WebP: Which Image Format Should You Use?
JPG vs PNG vs WebP, explained without the jargon. Learn what each image format is good at, where it fails, and how to pick the right one every time.
You exported the new logo, saved it as a PNG because someone once said PNG is higher quality, and now the client writes back: it's 9 MB and won't load on their homepage. Or you saved a screenshot as a JPG and the crisp text came out fuzzy, with grey smudges around every letter.
Either way you're now wondering what the difference between JPG, PNG, and WebP actually is, and which one you were supposed to use.
The short answer is that each format was built for a different job, and using the wrong one is what causes both problems above. This article walks through what each format is good at, where it falls down, and how to pick the right one without guessing.
JPG: Made for Photographs
JPG (also written JPEG) uses lossy compression. That means it shrinks a file by throwing away detail your eye is unlikely to notice, and it cannot get that detail back. For a photograph, with its thousands of subtle gradients, this is exactly right: you get a small file that still looks like the photo.
Where JPG struggles is anything with hard edges and flat color: text, logos, screenshots, line art. The same compression that smooths a sky into a small file leaves visible smears, called artifacts, around sharp boundaries. JPG also has no transparency. Every JPG is a solid rectangle, so a logo saved as JPG arrives with a white box behind it.
Use JPG for photos, and really only for photos.
PNG: Made for Graphics and Transparency
PNG uses lossless compression. Nothing is thrown away, so the image you save is pixel-for-pixel the image you open later. That makes it the right choice for screenshots, logos, icons, diagrams, and anything with text or sharp edges, where JPG's artifacts would show.
PNG's other strength is transparency. A PNG can have a see-through background, so a logo drops cleanly onto any color underneath instead of sitting in a white box.
The catch is file size. Because PNG keeps every pixel, a photograph saved as PNG can be several times larger than the same photo as a JPG, with no visible benefit. PNG is built for graphics, not photos.
WebP: The Modern All-Rounder
WebP is a newer format that can do both jobs. It supports lossy compression like JPG and lossless compression like PNG, and it supports transparency like PNG. At a similar visual quality, a WebP file is usually noticeably smaller than the equivalent JPG or PNG, which is why it has become the default for images on fast websites.
The one thing to know is support. Every current browser (Chrome, Firefox, Edge, Safari) has displayed WebP for years, so for the web it is a safe choice. Some older desktop software and a few printing services still won't accept it, so if you're handing a file to a system you don't control, JPG or PNG is the safer hand-off.
When the Wrong Format Bites
Here is the quick version:
| JPG | PNG | WebP | |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes | Yes |
| Best for | Photos | Graphics, text, logos | Web images of any kind |
| File size for a photo | Small | Large | Smallest |
The designer whose logo won't load
A designer exports the new brand logo as a PNG and emails it to the client. The reply comes back fast: "this is 8 MB, it won't load on our site." The PNG was holding a full photographic background at lossless quality, every pixel preserved, when the page only needed a small, fast-loading image. PNG did its job perfectly. It was just the wrong job.
The screenshot that came out fuzzy
The same designer, a week later, saves a screenshot of an app's interface as a JPG to keep the file small. Now the edges of every letter have a halo of grey blocks around them, and thin lines look smudged. That is JPG throwing away detail it decided no one would miss, on exactly the kind of sharp-edged image where the loss is obvious. Two opposite mistakes, both from picking a format by habit instead of by what the image is.
Converting Between Them
You don't have to re-export from the original file to fix either of these. You can convert what you already have, right in your browser, with nothing uploaded to a server and no account to create.
How the designer gets the logo loading
For the designer's heavy logo, the fix is to convert the PNG to WebP: it keeps the transparency and drops the file from megabytes to a few hundred kilobytes, so the page loads. The same look at a fraction of the size.
How the designer fixes the fuzzy text
For the designer's screenshot, the fix runs the other way. They convert it back to PNG and the text gets its clean edges again, because PNG keeps every pixel instead of guessing.
And when a system simply refuses anything else, which still happens with older upload forms and some printers, a PNG, WebP, or HEIC file can be converted to JPG, the format every site and printer accepts.
The Short Version
Use JPG for photographs, PNG when you need transparency or crisp text, and WebP when you want a smaller file that still looks the same on the web. Pick by what the image is, not by which format you used last time, and most of these problems never come up.
