WebP is a web image format that reaches a smaller file at the same apparent quality than JPEG, mostly by predicting blocks of the image from their neighbours rather than storing every block from scratch. A smaller file is a faster page, and page speed is one of the few image decisions a search engine measures directly.
Google puts the saving at 25 to 34% against JPEG. We measured our own photographs and got 14 to 20%, which is a real saving and not the advertised one. The full comparison against JPEG, PNG and AVIF has the numbers and the files they came from.
Yes, and it stays free. The conversion is done by your own browser, not by a server we pay for, so there is no cost to us per image and nothing to meter. No account, no watermark, no queue, no daily cap.
What we do charge for is the other half of the job. Resiqo reads a whole folder of photographs, writes each one a descriptive filename and its alt text, then resizes and converts the lot and hands it back as a single zip. That part uses a model, which costs money to run.
Resiqo does this to a whole batch, and names every file while it is there. Try the naming on 3 images a day with no account, or 20 a month with a free one.
