Free online tools that respect your privacy
Dasigba is a growing collection of free, no-sign-up tools for the small jobs that come up every day — calculating a loan repayment or a percentage, resizing and compressing an image, generating a strong password, formatting JSON, converting a Word file to PDF, or working out Philippine take-home pay and government contributions. There is nothing to install and no account to create; open a tool and it works.
What sets these tools apart is where the work happens. Instead of uploading your files and data to a server, every tool runs entirely inside your own browser using standard web technologies. Your photos, documents, text and numbers never leave your device — which keeps them private, makes each tool fast even on large files, and lets many of them keep working when you are offline.
Private by design
Files and inputs are processed on your device and are never uploaded or stored.
Fast and free
No sign-up, no paywall, no waiting on a server — tools load and run instantly.
Works everywhere
Mobile-first and responsive, so every tool works on phones, tablets and desktops.
