Questions
Is WEBP safe to use on a live website?
Yes. Every current browser has supported it for years, including Safari since 2020. The only real holdouts are Internet Explorer and some very old email clients.
How much smaller will my images get?
Typically 25–35% smaller than an equivalent-quality JPEG, and often far more than that against PNG for photographic content.
Which file types can I use?
JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. Because decoding is handled by your browser rather than a conversion server, support tracks whatever your browser can already open.
Is there a file size limit?
No imposed limit — there is no server quota to hit. The real ceiling is your device's memory, since the whole file is held in RAM while it is processed. Desktop browsers cope with very large files; phones give up sooner.
What are the limits on quality?
It accepts 10 to 100%, starting at 85%.
