Frequently asked questions
Are RaahUPSC Tools free?
Yes. All 203 tools are free to use with no sign-up, no watermark and no daily limit.
Are my files uploaded to a server?
No. PDFs, photos, videos and spreadsheets are processed by JavaScript and WebAssembly inside your browser, so they never leave your device.
Which tools are made for UPSC and SSC aspirants?
The Prelims negative marks calculator, score simulator, age and attempts calculator, UPSC Syllabus 2027, Mains answer word checker, directive keywords guide, GS4 psychology and quotes libraries, and the SSC 65-day tracker.
How do I resize a photo or signature for an exam form?
Use the Image Resizer to set exact pixels, centimetres or a target size in KB, and Add Name & Date to Photo to stamp your name and the date as UPSC and SSC forms require.
Why is the first video or AI tool slow?
Video and audio tools download the FFmpeg engine (about 31 MB) and AI tools download a model the first time you use them. Your browser then caches them, so later uses start quickly.
Do the tools work on mobile?
Yes. Every tool works in Chrome, Safari, Edge and Firefox on Android, iPhone, iPad and computers. Large videos are faster on a laptop.
