About Shrink My Tools

Shrink My Tools is a small collection of free, browser-based utilities built for everyday tasks — resizing images, generating QR codes, merging PDFs, formatting JSON, and more — without needing to sign up, install anything, or upload your files to a server.

Why it's different

Most "free" online tools work by uploading your file to a server, processing it there, and sending it back. That means your files pass through someone else's infrastructure, and there's always a wait for the upload and download. Every tool on Shrink My Tools runs entirely in your browser using JavaScript and WebAssembly — nothing is ever uploaded, so there's no wait and no privacy trade-off.
