A few useful answers.
Help & contactWhere are my images and text processed?
All currently available tools run in your browser. Your PDFs, images, text, grades, JSON and generated passwords are not uploaded to Tool Fera.
How do favorites and recent tools work?
Only tool identifiers are saved in this browser’s localStorage. Your inputs and files are never included. You can clear both lists from the homepage.
Can I use the tools on my phone?
Yes. The tools support modern mobile browsers. Large images may need more memory or processing time on older devices.
Which tools can I use right now?
Working tools cover PDF editing and conversion, image resizing and cropping, text counters and case conversion, image OCR, JSON, UUIDs, color conversion and encoders, QR codes and passwords, and everyday and student calculators. Browse the collections to see each tool’s inputs, guidance and limits.
Do I need an account?
No. Open a tool and use it directly. Favorites and history are optional and stored only in your browser.
