Privacy and security
iChoosePDF is built around browser-first PDF processing. When a tool can complete a task locally, the document stays on your device and does not need to be uploaded just to finish the job.
For sensitive files, review the output before sharing, use strong passwords where appropriate, and keep an original copy of important documents.
FAQs
Is the output guaranteed to pass every PDF/A validator?
No. This tool prepares a cleaner archival PDF, but strict PDF/A conformance should be checked with the validator required by your archive or institution.
Why is PDF/A different from a normal PDF?
PDF/A is intended for long-term preservation and has stricter rules around fonts, metadata, encryption, color, and external dependencies.
Is iChoosePDF free to use?
Yes. The core PDF tools are free to use in your browser, with no account required for ordinary document tasks.
Are my files uploaded to a server?
iChoosePDF is designed for browser-first processing. When a tool can complete the job locally, your files stay on your device instead of being uploaded.
Can I use this on mobile?
Yes, the tools work in modern mobile browsers. Larger PDFs are usually easier to manage on a desktop or laptop because they need more memory and screen space.
