Software that runs in your browser.
Lifetime Labs is a small software shop building focused web tools. Everything runs locally on your device — your files stay with you.
Products
A small, curated catalog.
We'd rather ship fewer things that we care about than a sprawling suite. Every tool here runs entirely in your browser.
Paper
Merge, split, compress, and convert PDFs locally.
A focused PDF toolkit that runs entirely in your browser. No uploads, no accounts, no waiting.

PrivacyNotes

What we stand for
Software, built patiently.
Pay once, own forever
One-time purchases, no subscriptions. When you buy software, you own it — no monthly drip, no license expiry, no surprise renewal emails.
Runs in your browser
Our tools execute on your own device. Files you drop in don't leave your browser — no uploads, no server-side copies, no cloud processing.
Independent
A one-person shop, not a VC-backed startup with a shutdown risk. We don't collect data, we don't track users, and we don't need growth charts.
About
A quiet, independent software shop.
Lifetime Labs makes small, useful things. We ship tools that run in your browser because that's the model we want to use ourselves — open a page, do the thing, close the tab, no residue.
