Quick answer for what is webp
WebP is an image format developed by Google that supports both lossy and lossless compression, transparency, and animation. It typically produces smaller files than older formats and is supported by every current major browser.
If you keep seeing WebP downloads and website assets, you are looking at one of the formats that has become central to modern web image optimization. Its appeal is simple: smaller files with useful quality retention, plus the ability to handle photos, graphics, and transparency in a single format.
That does not mean WebP replaces every other format. It means it gives web publishers another strong option, especially when page speed and bandwidth matter, and it is worth understanding exactly where its limits are before you convert an entire library.

What matters most before you start
Why WebP became popular
WebP became popular because websites need lighter assets without turning every image into a visibly damaged file. It was introduced by Google and combines two compression modes in one container: a lossy mode derived from video compression research, and a lossless mode that outperforms PNG on many graphics.
The practical effect is that a photo can be delivered as a small lossy WebP, while a logo or screenshot can be delivered as a lossless WebP, and both use the same file extension. For a team trying to standardise on one modern format, that range is the main selling point.
Where WebP fits best
WebP works well as a web delivery format for photos, article covers, product images, and many general-purpose graphics. Because every current version of Chrome, Firefox, Safari, and Edge supports it, an ordinary website can serve WebP directly without a compatibility layer.
It is not always the right choice for every editing workflow or every upload destination. Some document portals reject WebP outright, older desktop applications cannot open it, and some print and design pipelines expect JPG, PNG, or TIFF. A format that is perfect on a web page can be useless on a government form.
| Format | Strength | Keep using it when |
|---|---|---|
| WebP (lossy) | Small photo files, wide browser support | The destination is a modern web page |
| WebP (lossless) | Smaller than PNG on many graphics | You need transparency or crisp edges for the web |
| JPG | Universal compatibility | A portal, app, or printer requires JPG |
| PNG | Exact, well-known lossless output | You need a guaranteed-compatible transparent asset |
| AVIF | Even smaller for some images | Your tooling and audience already support it |
How to think about WebP practically
The easiest way to think about WebP is as a modern delivery option. Keep your originals, then export WebP when you want a lighter copy for web use. If the site is built by hand or through a framework, you can also serve WebP only to browsers that accept it and fall back to JPG for the rest, which removes the compatibility concern entirely.
That mindset keeps your workflow flexible. You get the speed benefits without locking yourself into one format too early, and you never end up with a folder full of WebP files that a client or a form cannot open.
Keep the original master
Retain the JPG, PNG, or RAW source so you can re-export to any format later without another round of lossy conversion.
Export WebP for delivery
Create the WebP as a publishing copy, sized to the dimensions the page actually uses.
Check the destination
Confirm the platform accepts WebP before replacing existing assets. If it does not, keep JPG or PNG for that path.
Common questions about what is webp
Is WebP better than JPG?
For web delivery, WebP usually produces a smaller file at comparable quality, and unlike JPG it also supports transparency. It is not better for every case: JPG still wins on universal compatibility, and some portals will not accept WebP at all.
Can I use WebP for logos and graphics?
Yes, using lossless WebP. It supports transparency and usually beats PNG on file size for web graphics. Test sharp edges and thin lines after conversion, since aggressive lossy settings can soften them.
Do all browsers support WebP?
Every current major browser does, including Chrome, Firefox, Safari, and Edge. The gaps are outside the browser: older desktop image viewers, some office software, and certain upload portals may not recognise the format.
Should I keep original files after converting to WebP?
Yes. Keep your masters in a universal format so you can convert to whatever a future destination requires. Deleting the original leaves you re-compressing an already-compressed file.
Is WebP the same as GIF for animation?
They are similar in purpose but WebP usually produces smaller files with better colour. For any animation longer than a few seconds, a short video file is usually smaller and smoother than either.
