About Swoopty
Swoopty brings 65 everyday tools together in one fast, simple website: pdf tools, image tools, developer tools, text tools, everyday tools. Everyday tools. Done in a swoop.
The idea is simple: when you need to merge a PDF, shrink a photo or check some JSON, you shouldn’t have to sign up, sit through ads or wonder where your files went.
How it works
- Most tools run in your browser. The work happens on your own device, so your files and text are not uploaded.
- AI tools also run in your browser. Upscaling and background removal download an AI model from Swoopty once, then process your image on your device.
- A few tools need our server: Word ⇄ PDF conversion (LibreOffice) and adding or removing PDF passwords (qpdf). These tools say so before you start, and files are deleted after you download the result (15 minutes at most).
