Frequently Asked Questions
Practical answers before you start working with your files.
Is TechSathi free?
Enabled core tools are free within their visible limits. There are no active subscriptions or payment forms. An administrator may adjust limits to keep resources available.
Why do I need an account?
An account protects access to your processing history, saved documents and private result downloads. Email verification is required before processing. Public guides and policy pages can be read without an account.
How long can I download a result?
Generated files expire after 24 hours. Use a fresh signed link from your account history while the result is still available. Download the files you need and keep your own backup.
Can I replace existing PDF text?
The PDF editor can replace supported digital text runs. Scans, outlined text and some embedded PDF objects cannot be edited as ordinary text. Use OCR or the original source document for those cases. Editing and overlays are not secure redaction.
Will OCR always be correct?
No. Printed text in clear images works best. Review names, numbers and punctuation. Handwriting, tables, low contrast and complex layouts can reduce accuracy.
Does it work on a phone?
The interface adapts to phones, tablets and desktops. Large PDFs and local OCR may need more memory than a phone has available. Try a smaller file or a desktop browser when an operation is too large.
What if a file fails?
Check that it opens in its original application, confirm the supported format and visible limits, then try a smaller copy. Password-protected PDFs need the supported password-authorized unlock workflow.
Can I delete my data?
Members can remove individual generated files, saved documents and their account from the workspace. The Data deletion page explains what each action covers.
