FAQ
Questions about Flatten PDF
Why flatten a PDF?+
Flattening merges form fields, annotations and layers into the page so nothing can be edited or hidden, and the file opens identically everywhere.
Will the text remain selectable?+
In “Keep text” mode, yes. “Convert to image” rasterizes pages for maximum compatibility and stops any text extraction.
Are links preserved?+
Tick “Keep links” and clickable links survive flattening.
Are my files uploaded anywhere?+
No. Everything runs in your browser; your file never leaves your device.
