Practical, evergreen pieces on local-first productivity — how to optimize PDFs for email, build browser-only image pipelines, set up a developer toolkit that never uploads your data, and the architecture behind it all.
The case for processing your files in the tab you already have open — not on someone else's server.
Mail servers have a 25 MB hard cap. Here's how to combine, shrink, and send a clean PDF entirely in your browser.

JSON, Base64, regex, hash, diff, JWT — the everyday utilities developers reach for, all in one place, all local.

Install as a PWA, add the browser extension, run the desktop build — three ways to make SnapToolz feel like installed software.
Every guide is hand-written by the SnapToolz team. We mention competitors and trade-offs honestly — local-first beats cloud-first on privacy, latency, and reliability, but the cloud still wins for jobs measured in terabytes or for ML measured in dozens of billions of parameters. We're trying to be useful, not triumphalist.
