Frequently asked questions
General questions about the site. Questions about a specific tool are answered on that tool’s page.
Are all the tools free?
Yes. Every tool is free, with no account, trial or premium tier.
Do I need to install anything?
No. The tools run in any current version of Chrome, Edge, Firefox or Safari on desktop or mobile. JavaScript must be enabled.
Are my files and text uploaded?
No. Processing happens in your browser, on your device. The privacy policy explains this in detail and how you can verify it.
Do the tools work offline?
Once a tool page has loaded, most tools keep working if your connection drops, because they do not need a server. Tools that load an extra library — the PDF tools and the JavaScript minifier — need a connection the first time you use them.
Is there a limit on file size?
Images can be up to 25 MB each and PDFs up to 100 MB, to keep browsers responsive. The practical limit also depends on your device’s memory; phones handle less than computers.
Why does a tool show a different result from another website?
Tools can use different methods or assumptions — reading speed, rounding, which characters count as a word. Each tool page explains the method used here, so you can compare.
Can I use the results commercially?
Yes. Results you create are yours. See the terms and conditions for details.
Do your SEO tools show search volume or rankings?
No. That data comes from paid providers and search engines. Our tools analyse the content you supply and never invent figures.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. A few features depend on the browser: “pick from screen” in the colour picker works only in Chromium-based browsers, and HEIC images open only in Safari.
How do I report a problem or suggest a tool?
Use the contact page. For problems, include the tool, what you entered, what you expected and your browser and device.
