WebP vs PNG vs JPG
PNG, JPG and WebP cover almost every image you will put on the web. They are not interchangeable — picking the right one keeps pages fast without wrecking quality.
The quick version
- JPG — photographs. Small files, no transparency, lossy.
- PNG — logos, icons, screenshots, anything needing sharp edges or transparency. Lossless, larger.
- WebP — the modern all-rounder. Does both lossy and lossless, supports transparency and animation, and is usually smaller than either.
Side by side
| JPG | PNG | WebP | |
|---|---|---|---|
| Compression | Lossy | Lossless | Both |
| Transparency | No | Yes | Yes |
| Animation | No | No | Yes |
| Typical size | Small | Large | Smallest |
| Support | Universal | Universal | All modern browsers |
| Best for | Photos | Graphics, transparency | Web images, speed |
So which should you use?
For a website where load speed matters, WebP is usually the best default — it typically beats both JPG and PNG on size at the same quality. Keep PNG when you need guaranteed lossless quality or maximum compatibility (for example a logo you will hand to a printer), and JPG for photos going somewhere that may not support WebP.
Every conversion runs in your browser, so nothing is uploaded and there is no limit on how many you do.
Frequently asked questions
Is WebP better than PNG and JPG?
For the web, usually yes — it produces smaller files at similar quality and supports transparency and animation. The main reason to stick with PNG or JPG is guaranteed compatibility with very old software.
Does converting PNG to WebP lose quality?
Only if you choose lossy WebP. WebP also has a lossless mode that preserves the image exactly while still shrinking the file.
Do all browsers support WebP?
All current major browsers do. A small number of very old applications may not, which is when PNG or JPG is the safer choice.
