What Is WebP, and Should You Use It?
It compresses better than JPG and supports transparency like PNG. So what's the catch with WebP, and should you actually switch?
WebP is a more modern image format built specifically to do what JPG and PNG each do, only more efficiently - and for most everyday use, especially anything going on a website, it's a genuine upgrade over both.
What makes WebP different
WebP compresses photographic content more efficiently than JPG, meaning a similar-looking image typically comes out as a smaller file. It also supports transparency the way PNG does, which historically meant choosing between JPG's smaller size and PNG's transparency support - WebP offers both at once.
Where WebP still falls short
Browser support is no longer a real concern - every modern browser handles WebP natively. The remaining gaps are in older or more specialized software: some older image editors, certain print workflows, and a handful of apps that simply haven't added WebP support yet. If you know a file needs to go somewhere with unclear WebP compatibility, it's worth checking first or keeping a JPG/PNG version as a fallback.
When switching to WebP makes sense
- Images for a website, where smaller file sizes directly improve page load speed
- Any image that currently needs PNG for transparency but doesn't need PNG's lossless quality
- General photo sharing where the smaller file size is a meaningful benefit and the destination supports it
When to stick with JPG or PNG instead
If a file is headed somewhere with unclear or known-limited software support - certain older content management systems, some print services, specific third-party integrations - sticking with the more universally supported JPG or PNG avoids compatibility headaches. Converting is easy enough to do later with a format converter once you're confident WebP will be accepted.
Frequently asked questions
Is WebP supported everywhere now?
All modern browsers support WebP natively. The main gaps are older software and some specific tools or apps that haven't added support, which is worth checking if you have a specific downstream use case.
Is WebP always smaller than JPG?
Generally yes, at a comparable visual quality - WebP's compression is more efficient than JPG's, often producing meaningfully smaller files for the same image.
Can WebP have a transparent background like PNG?
Yes - WebP supports transparency, which is one of the reasons it can often replace PNG as well as JPG for many use cases.
