WebP is a modern image format created by Google that has quietly become the default choice for fast websites. If you have ever wondered whether to switch your images to .webp, here is what it does and when it makes sense.
Why WebP exists
For years the web was split between two formats: JPG for photos and PNG for logos and transparency. WebP was designed to replace both. It supports:
- Lossy compression like JPG, but more efficient
- Lossless compression like PNG
- Transparency (an alpha channel)
- Animation, like GIF
In practice, WebP files are typically 25–35% smaller than an equivalent JPG or PNG at the same visual quality. On an image-heavy page, that difference adds up to faster loads and lower bandwidth.
When to use WebP
Use WebP when:
- You control a website and want it to load faster — smaller images improve Core Web Vitals and SEO.
- You need transparency and small size at once, which JPG cannot give you.
- Your visitors use modern browsers (all current versions of Chrome, Edge, Firefox and Safari support WebP).
When to stick with JPG or PNG
WebP is not always the answer:
- Sharing a file with someone who might open it in older software — JPG and PNG are universally supported.
- Uploading to a platform that rejects
.webp(some older tools and printers still do). - Print workflows, which typically expect JPG, PNG or TIFF.
When in doubt for compatibility, a plain JPG or PNG is the safe fallback.
How to convert to and from WebP
These free tools run entirely in your browser — nothing is uploaded:
- PNG to WebP — shrink logos and graphics while keeping transparency.
- JPG to WebP — make photos smaller for the web.
- WebP to PNG — get a widely compatible, lossless copy.
- WebP to JPG — for tools that only accept JPG.
The rule of thumb: use WebP on your own website for speed, and convert back to JPG or PNG whenever you need to hand a file to someone else.
