Flatten PDF
BETALock form fields and annotations into the page bitmap.
About Flatten PDF
Flatten PDF rasterizes each page at the chosen DPI and rebuilds the document as a non-editable archival PDF. Form fields, annotations, signatures, and JavaScript are baked into the page bitmap — readers see exactly what you saw.
Use Flatten when you need a tamper-evident archive copy: the result is a stable, image-based PDF that won't shift across readers.
How it works
- 1
Upload the PDF.
- 2
Pick a DPI (150 small, 200 recommended, 300 print).
- 3
Download the flattened PDF.
When to use it
- Archive completed forms so values cannot be edited.
- Lock annotations and comments into a final-version PDF.
- Produce a sealed copy that displays identically on every reader.
