Help Center — Techsinghge Smart Tools

Getting started

No account needed for the toolkit. Every PDF, image, and Excel/Office tool works instantly — just open a tool page and drop your file in.
AI tools need a free sign-in. Create a free account from the sign up page to start generating with any of the 45 AI tools.
Nothing is uploaded. The PDF/image/Excel toolkit processes your file entirely inside your browser tab — there's no server involved, so there's no upload wait and no file-size limit tied to a plan.

Common questions

A tool isn't working — what should I check first?

Make sure you're on an up-to-date version of Chrome, Edge, Firefox, or Safari. Try a smaller or simpler file first to rule out an unusual file structure, and check that JavaScript isn't blocked by a browser extension.

Why do the AI tools need sign-in but the PDF tools don't?

The PDF, image, and Excel tools run entirely on your device, so there's nothing to gate. The AI tools call a hosted AI model through a secure backend, so a free account lets us keep that usage fair and spam-free.

I forgot my password.

Use "Forgot password?" on the login page to get a reset link emailed to you.

Is my file or data ever stored on your servers?

No, for the PDF/image/Excel toolkit — see our Privacy Policy for full details. AI tool prompts are sent to a backend only to generate your result.
