You upload a photo and your image editor asks: save as WebP, JPG or PNG? If you have ever stared at that choice and picked one at random, you are not alone. These three formats look similar on the surface but behave very differently — and picking the wrong one can mean bloated file sizes, quality loss, or images that simply will not open on an older device. This guide cuts through the noise and tells you exactly which format to use, and when.
The short answer: WebP for almost everything on the web, JPG for photos you share or print, PNG for logos and anything that needs a transparent background. But the long answer matters — because there are real situations where each format has a clear edge, and understanding them will save you time and frustration.
Before comparing them side by side it helps to understand what each format was designed for, because that design intent explains almost every difference between them.
WebP
Developed by Google in 2010, WebP was built specifically for the web. It uses more advanced compression than JPG — producing smaller files at the same visual quality — and supports both lossy and lossless modes as well as transparency.
JPG / JPEG
The oldest of the three, JPG has been around since 1992. It uses lossy compression — every time you save a JPG, some data is permanently discarded — but it produces small files that open on literally every device and application ever made.
PNG
PNG uses lossless compression — no quality is lost when saving. It also supports a full alpha channel (transparency), which JPG and standard WebP both lack in the same way. The trade-off is larger file sizes, especially for photographs.
Here is how the three formats compare across the metrics that matter most for everyday use:
| Feature | WebP | JPG | PNG |
|---|---|---|---|
| Compression type | Lossy & lossless | Lossy only | Lossless only |
| File size (photo) | Smallest | Medium | Largest |
| Image quality | Excellent | Good | Perfect |
| Transparency support | Yes | No | Yes |
| Browser support | 96% (all modern) | 100% | 100% |
| App / software support | Most modern apps | Universal | Universal |
| Best for photos | Yes | Yes | No (too large) |
| Best for graphics / logos | Yes (lossless mode) | No | Yes |
| Animation support | Yes | No | Limited (APNG) |
| Print use | Not recommended | Yes | Yes |
WebP delivers roughly 25–35% smaller files than JPG at the same visual quality — which translates directly into faster page load times, better Core Web Vitals scores and improved Google rankings. Every major browser has supported WebP since 2020.
If you have a library of existing JPG or PNG images on your site, converting them to WebP is one of the fastest wins for page speed you can make. Use the free image converter to batch convert up to 20 images at once.
JPG has one irreplaceable advantage over every other format: it works everywhere, without exception. Every camera, phone, printer, email client, design application and social media platform that has ever existed accepts JPG.
Saving a JPG at 100% quality does not mean perfect quality — it means minimum compression. Quality 85 is visually indistinguishable from 100 for most photos and produces a file roughly half the size. Use the image compressor to find the optimal quality level for any photo.
PNG is the right choice whenever image quality cannot be compromised at all — and especially when you need a transparent background. Because PNG uses lossless compression, every pixel is preserved exactly as it was when you saved the file.
Saving photographs as PNG is one of the most common image mistakes on the web. A single product photo saved as PNG can be 3–8 MB — compared to 150–400 KB as WebP. If you have PNG photographs on your website, convert them to WebP immediately.
| Format | File Size | Saving vs PNG | Visual Quality |
|---|---|---|---|
| PNG | 1.8 MB | — | Perfect (lossless) |
| JPG (quality 85) | 320 KB | 82% smaller | Excellent |
| WebP (quality 80) | 210 KB | 88% smaller | Excellent |
AVIF is the newest contender — files 40–50% smaller than JPG, now supported in Chrome, Firefox, Edge and Safari 16+. HEIC is Apple’s default iPhone format — efficient but limited outside the Apple ecosystem. If you have HEIC photos, convert them to JPG or WebP first. GIF is only worth using for simple looping animations.

For web use, yes — WebP produces smaller files at the same visual quality, which means faster page loads and better SEO. The average WebP file is 25–35% smaller than an equivalent JPG. The only situation where JPG has an edge is compatibility: JPG works in every piece of software ever made, while WebP requires a modern browser or application. For sharing photos by email or printing, stick with JPG.
Does converting JPG to WebP reduce quality?
Converting a JPG to WebP involves re-encoding the image, which means a small amount of additional quality loss is technically possible. In practice, converting at quality 80–85 produces results that are visually indistinguishable from the original JPG. Use the free converter to compare the results yourself.
Can I use WebP on all websites?
Yes — all modern browsers including Chrome, Firefox, Safari, Edge and Opera support WebP natively. As of 2026, global WebP browser support sits above 96%. The only edge case is very old browsers (Internet Explorer, Safari older than version 14) which do not support WebP.
Why are my PNG files so much larger than JPG?
PNG uses lossless compression — it preserves every single pixel exactly as-is. This is ideal for graphics and logos but terrible for photographs. JPG and WebP use lossy compression that discards imperceptible detail to achieve much smaller file sizes. If you have photographs saved as PNG, converting them to WebP or JPG will typically reduce file size by 80–90%.
What is the best image format for Google ranking?
Google does not rank pages based on image format directly — but page speed is a ranking factor, and image file size is one of the biggest contributors to slow page speed. Using WebP instead of JPG or PNG reduces image file sizes significantly, which improves Core Web Vitals scores (specifically LCP). Google’s own PageSpeed Insights recommends serving images in next-gen formats like WebP and AVIF.
Should I use PNG or WebP for logos?
Both work well for logos. PNG is the traditional choice with universal support. WebP lossless mode produces smaller files with identical quality and also supports transparency — so for a website logo, WebP lossless is a slightly better choice. For logos used in documents or print materials, PNG or SVG are safer options.
If you take one thing from this guide: stop using PNG for photographs on your website. Switch to WebP for website images, keep PNG for logos and transparent graphics, and use JPG when compatibility with older software or print is a priority.
