Is KraftDoc completely free to use without limits?

Yes. All utility tools are free with zero subscription paywalls, no forced watermarks, and no sign-up registration.

What is the maximum file size limit for merging or converting?

Because files are processed directly using your device's native RAM and CPU rather than a shared cloud server, KraftDoc can easily handle large multi-hundred-megabyte documents and architectural drawings.

Can KraftDoc work without an active internet connection?

Yes. Once the web application is loaded in your browser or installed via PWA, core processing engines run fully offline.

Does KraftDoc save or retain a backup copy of my files?

No. KraftDoc does not maintain any server storage, cloud databases, or temporary caches. Closing the browser tab cleans all document memory immediately.

Frequently Asked Questions

Clear answers regarding document safety, client-side execution, browser support, and privacy.

Document Security & Privacy

Are my PDF, Word, and Excel files safe when using KraftDoc?

Yes, 100%. KraftDoc processes everything locally on your computer inside your web browser. Unlike cloud converters, your confidential documents, tax forms, or contracts never travel across the internet or touch remote servers.

Does KraftDoc save or retain copies of my uploaded documents?

No. We do not have any cloud databases, storage buckets, or temporary caching servers. Files exist solely in your browser's active RAM session. As soon as you refresh or close the tab, the data is permanently erased.

Can I safely process confidential corporate drawings and financial records?

Yes. Enterprise teams, chartered accountants, and design engineers regularly use KraftDoc because the client-side architecture satisfies strict non-disclosure (NDA) and regulatory compliance requirements (such as GDPR and India DPDP Act 2023).

Limits & Technical Performance

What is the maximum file size limit for merging or splitting?

Because execution is powered by your local machine rather than a limited web server, there are no artificial file limits. You can easily process large multi-hundred-megabyte PDF sets, limited only by your computer's RAM.

Can KraftDoc work offline without an active internet connection?

Yes. Once the web application files and WebAssembly dependencies are loaded into your browser cache (or when installed as a desktop/mobile PWA app), processing takes place completely offline.

Which operating systems and browsers are supported?

KraftDoc is fully compatible with Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Brave across Windows, macOS, Linux, Android, and iOS devices.

Pricing & Watermarks

Is KraftDoc free to use? Are there hidden fees?

All standard tools are 100% free with no monthly subscription paywalls, no forced trial accounts, and no hidden charges.

Do you add watermarks to exported documents?

Never. KraftDoc preserves your exact original layout, formatting, and vector fidelity without injecting promotional watermarks, stamps, or logos.

Contact Support

Can I convert Word, Excel, and PowerPoint files to PDF?

Yes. Our Office Converter Suite converts DOCX, XLSX, and PPTX documents into vector-accurate PDFs and vice versa directly in browser memory without sending private office files to external servers.

How does the Image Suite process files locally?

The Image Suite utilizes browser WebAssembly and HTML5 Canvas to convert PDF pages to JPG/PNG, compress images, add watermarks, and combine photos into PDFs entirely in client-side RAM with zero uploads.

Can I rotate specific pages or add custom page numbers?

Yes. You can rotate individual pages or the entire document permanently by 90, 180, or 270 degrees. Our Page Numbers & Watermark tool also lets you stamp dynamic "Page X of Y" counters or diagonal security marks instantly.
