A few useful answers.
Answers about privacy, offline use, limits and PDF processing.
Are files uploaded?
The PDF tools run locally in your browser. The website itself makes normal hosting requests, and OCR downloads software and language data. Your selected documents are not sent for remote processing.
Does it work completely offline?
This release is a website, not an installed offline application. Internet is required to load the application and OCR assets. Some already loaded operations can continue without a connection, but complete offline availability is not guaranteed.
What are the limits?
Use files up to 40 MB and PDFs up to 250 pages. Device memory and rendered page size can impose lower practical limits, particularly on phones. Large drawing pages may require lower resolution.
Can I unlock, redact or convert to Word?
Those operations are not offered in this release. Watermarks are not redaction. Text recognition is not a faithful Word conversion. Password-protected files may be rejected.
How much does it cost?
The available browser tools are free. There is no account or subscription requirement. Any future paid offering will be described separately.
