About Toolcairn

Toolcairn is a free collection of online tools for everyday tasks — compressing PDFs, resizing images, generating QR codes, formatting JSON and more. Everything runs in your browser. No signup. No ads tracking you around the web. No files kept longer than needed to deliver the result.

Why we built it

Most online utility sites are slow, covered in dark-pattern upsells or demand an account to do basic things. Toolcairn is a push in the other direction: fast, simple, and free.
