WebP, or unofficially pronounced as weppy, is a picture structure introduced by means of Google Builders round 5 years in the past. in case you are a internet fashion designer, or a developer who strives to scale back and optimize your symbol document length, what WebP is able to must put a grin to your face.
Briefly, listed here are one of the crucial vital stuff you wish to have to learn about this not-so-new-but-still-cool symbol structure:
- WebP is going by means of the document extension of .webp.
- WebP adopts each lossy and lossless compression.
- WebP lossy pictures are probably 25-34% smaller than JPEG.
- WebP lossless pictures are probably 25% smaller in comparison to PNG.
- WebP helps lossless transparency, i.e. PNG with alpha channel.
- WebP helps animation. i.e. animated GIFs.
In a nutshell, WebP is able to considerably lowering JPEG, GIF, PNG’s symbol document length. Right here’s a refresher on WebP you must take a look at earlier than we move into the thrill stuff.
An Experiment
The most productive issues about claims at the Internet is that we will be able to at all times run experiments to take a look at the truthfulness and authenticity. Listed here are some experiments I did to determine how small a picture can probably get after they’re transformed from more than a few symbol codecs (JPEG, PNG and GIF) to WebP.
1. JPEG – Lossy Symbol
Right here’s a random JPEG symbol I grabbed from Pexels. Authentic filesize – 165kb. ↓
Symbol is optimzed with JpegMini. New filesize – 101kb. ↓
In spite of everything, the similar symbol is transformed to WebP structure. Ultimate filesize –
70kb. ↓
On a facet notice: Listed here are the other filesizes if the similar symbol was once transformed to the next codecs:
- GIF – 285kb
- PNG 8 – 241.2kb
- PNG 24 – 657.6kb
2. PNG – Lossless Symbol
Now, let’s check out with PNG with transparency. (Source). Authentic filesize – 587kb. ↓
Right here’s the picture optimized with tinypng. New filesize – 278kb. ↓
And finally, the picture transformed to WebP structure. Ultimate filesize – 112kb. ↓
3. Animated GIF
When transformed to WebP, a JPEG symbol went from 165kb to 70kb, whilst a PNG symbol went from 587kb to 112kb.
Let’s see how an animated GIFs fare:
- Original filesize – 6.8mb
- WebP filesize – 6.3mb
Abstract:
Right here’s a desk to summarize all the experiment:
| Lossy (JPG) | Lossless (PNG) | Animated-GIF | |
| Authentic | 165kb | 587kb | 6.8mb |
| Optimized with equipment | 101kb | 278kb | – |
| WebP structure | 70kb | 112kb | 6.3mb |
With out living a lot in mathematical calculations, the ones figures point out really extensive relief of document sizes, and judging from the pictures, you’ll be able to’t in reality inform the variation in relation to readability and backbone. Smaller, lighter document sizes with the similar stage of symbol high quality, WebP is undoubtedly price taking a look into.
Changing to WebP with Gear
In case you’re already on board and want to get started liberating pictures in WebP structure, let’s dive in and take a look at how you’ll be able to convert your pictures simply to this structure.

That’s it. Now let’s check out easy methods to convert pictures to WebP the use of command line.
Instructions to Convert/Revert
Listed here are the instructions to:
I – Convert JPEG / PNG symbol recordsdata to WebP structure
Layout:
cwebp -q [image_quality] [JPEG/PNG_filename] -o [WebP_filename]
Instance:
cwebp -q 80 instance.png -o instance.webp
II – Covert WebP symbol recordsdata again to PNG
Layout:
dwebp [WebP_filename] -o [PNG_filename]
Instance:
dwebp symbol.webp -o symbol.png
Extra: In case you perfer conversioni by way of different approach, listed here are directions for the use of Grunt and Gulp duties to transform JPG/PNG recordsdata to WebP.

Be aware: Simply idea you must know that I attempted it on Photoshop CC. Didn’t paintings there.
WebP Browser Reinforce
Finally, let’s speak about compatibility. Recently, you’ll be able to view WebP structure pictures at the following browsers (ref):
- Chrome / Chrome for iOS
- Opera / Opera Mini
No longer such a lot good fortune for FireFox and Safari, which nonetheless don’t reinforce WebP structure natively. Then again, you’ll be able to use WebPJS Javascript library to convert WebP pictures into dataURI string at the consumer web page.
Fall again to different symbol codecs
It’s at all times a good suggestion to make use of a fallback to keep away from appearing symbol mistakes because of unsupported browsers. On this case, the fallback can be to the picture in JPG or PNG structure. Right here’s the way you do it.
supply srcset="instance.webp 1x" kind="symbol/webp"> 
For this code, instance.jpg can be loaded if the consumer used Firefox or Safari.
