Why OneTimeApps
Most tools online today want your email and your card. Ours just want to help you finish the task.
No subscriptions
Pay-per-month tools for a task you do twice a year make no sense. Use ours free, whenever you need them.
Runs in your browser
No installs, no accounts. Open the tool, do the task, close the tab.
Privacy-first
Most tools process files locally. Nothing you don't need to upload gets uploaded.
Fast and no bloat
Small, focused apps that do one thing well instead of a dashboard you have to learn.
