Before you process a document.
How local processing, practical limits, advertising, and browser storage work in AmrrkPDF.
Are my PDF files uploaded to AmrrkPDF?
Most tools process document contents inside your browser and do not upload them to an AmrrkPDF application server. The browser may download runtime assets. OCR downloads language models, and timestamp tools can contact a selected timestamp authority using a cryptographic digest.
Is AmrrkPDF free?
Yes. The public tools can be used without an account or subscription. The service may display clearly identified advertising to help cover hosting and development.
What is the maximum file size?
AmrrkPDF does not advertise a universal maximum because browser memory, device power, document complexity, and the selected tool determine the practical limit. For very large files, close other tabs and work in smaller page ranges or batches.
Does every tool work offline?
No. Many operations can continue after required components are cached, but the site first needs to load and some tools download OCR models, fonts, conversion runtimes, web resources, certificates, or timestamp responses.
Why did a file fail?
Common causes include encryption, corruption, XFA or dynamic forms, unusual fonts, unsupported features, low browser memory, or a file that does not match its extension. Try decrypting or repairing it and test a smaller range.
Will conversion preserve the layout perfectly?
Not always. PDF and office formats represent layout differently. Fonts, tables, charts, macros, transparency, and scanned pages can require manual review after conversion.
Why are there ads and what data do they use?
Ads can fund the free service. When enabled, Google and its partners may process cookies, IP addresses, browser information, and advertising signals. Your document contents are not provided to advertisers by AmrrkPDF.
