Why AppsOcean?
Private by design
Files are processed locally with modern browser APIs. Nothing is uploaded or stored on a server.
Instant & free

Works everywhere
Phone, tablet or desktop — any modern browser. Light and dark mode included.
What is AppsOcean?
AppsOcean is a free collection of 51 online tools that help you get everyday digital tasks done in seconds. Instead of installing heavy desktop software or signing up for yet another service, you open a tool in your browser, use it, and move on — whether that’s merging PDF files, compressing images, creating a QR code, or calculating a loan EMI.
What makes AppsOcean different is where the work happens. Most “free online converters” upload your files to their servers. AppsOcean tools run entirely inside your browser using JavaScript and modern web technologies like Canvas, Web Workers and the Web Crypto API. Your documents, photos and text are processed on your own device and are never uploaded, stored or shared.
The tools cover PDFs, images, text editing, developer utilities, color and design, calculators, time management and a little fun — and every one of them works on phones, tablets and computers, in light or dark mode.
How AppsOcean works
Every tool follows the same simple, private workflow.

Search above, filter by category, or press Ctrl + K anywhere on the site to jump straight to the tool you need.
-
2. Add your file or data
Drag and drop files, paste text or type numbers. Everything is processed instantly on your device — nothing is sent to a server.
-
3. Download or copy the result
