Yes. There is no signup, no watermark and no usage limit. We build them to show how we approach performance and quality, and they are free for everyone.
No. The file, Excel, image and developer tools run entirely in your browser, so your files and data never leave your device. The website security checker is the one exception: it makes an ordinary web request from our server to the address you enter, and doesn't store the result.
Any current version of Chrome, Edge, Firefox or Safari. Image AVIF output needs a browser that can encode AVIF (Chrome and Edge); otherwise WebP is created automatically.
We keep adding tools, including a website security checker and more SEO utilities. Tell us what you'd like to see through the contact page.
