PNG to WebP: what to expect
WebP makes images for websites much lighter, which speeds up page loading. Screenshots and graphics usually shrink by 70 to 90 percent while still looking sharp.

| File | Result | Note |
|---|---|---|
| PNG (original) | 355.7 KB | — |
| WebP, quality 85 (default) | 35.6 KB | −90% |
Best settings
- Quality 85 works for most screenshots and photos.
- Use 90–100 for logos and text-heavy graphics so edges stay crisp.
- Transparency is kept — WebP supports it like PNG.
Common problems
- Text or edges look blurry. Raise the quality to 90 or more.
- The WebP is bigger than the PNG. Happens with tiny icons or simple flat graphics. Keep the PNG for those.
- An old program cannot open the WebP. All current browsers support WebP; for old software keep a PNG or JPG copy.
Quick answers

Yes in all current browsers (Chrome, Safari, Firefox, Edge). Some older desktop programs still need PNG or JPG.

About the PNG Format
PNG is a lossless image format that preserves every pixel of your image perfectly, no matter how many times you save it. It supports full alpha transparency, making it the go-to choice for logos, icons, and any image that needs to be placed over different backgrounds. PNG files are typically larger than JPEG files for photographs, but they excel at preserving sharp edges, text, and flat-color graphics.
PNG was developed in 1996 as a patent-free replacement for the GIF format. It was designed to improve upon GIF by offering better compression, true color support, and full alpha transparency.
Advantages
- Lossless compression — no quality loss
- Full alpha transparency support
- Perfect for screenshots, logos, and graphics
- Sharp text and edge preservation
Disadvantages
- Larger file sizes than JPEG for photographs
- No animation support (use APNG or GIF instead)
- Overkill for simple photographs where lossy is acceptable
About the WEBP Format
WebP is a modern image format developed by Google that provides superior compression for images on the web. It supports both lossy and lossless compression, transparency, and even animation — essentially combining the best features of JPEG, PNG, and GIF into a single format. WebP images are typically 25-35% smaller than comparable JPEG images at equivalent visual quality, making it an excellent choice for improving website loading speed.
WebP was introduced by Google in 2010 as part of their effort to make the web faster. It is based on the VP8 video codec technology. Browser support has grown steadily, and as of 2023, WebP is supported by all major browsers including Chrome, Firefox, Safari, and Edge.
Advantages
- 25-35% smaller than JPEG at similar quality
- Supports both lossy and lossless compression
- Transparency support (like PNG)
- Animation support (like GIF)
- Excellent for web performance and Core Web Vitals
Disadvantages
- Not universally supported in older software
- Some image editors still lack native WebP support
- Slightly slower to encode/decode than JPEG
