ao.tools is a growing collection of free online tools for everyday tasks — compressing and merging PDFs, counting words, resizing images, calculating percentages and loans, generating passwords and QR codes, and much more.
Why we built it
Too many “free” tools are slow, covered in pop-ups, or quietly upload your private files. We want tools that are fast, simple and respectful of your privacy. Most of ours run entirely in your browser, so your data never leaves your device.
How it’s funded
Every tool is free to use. The site is supported by unobtrusive advertising, and a Premium plan (ad-free with higher limits) is planned for people who want more.
