Frequently Asked Questions

Can I edit the actual text inside a PDF?

The editor focuses on annotation: highlighting, drawing, shapes, and comments layered over the document. Restructuring original text is handled by other tools such as redaction.

Are my annotations saved into the file?

Yes. Annotations are stored locally and can be flattened into the PDF so they appear in any standard PDF reader.

Are my files uploaded to a server?

No. PDFMiniFly processes everything locally inside your browser. Your document never leaves your device, and once the app is installed it also works offline.
