About Flatten PDF
Flatten PDF burns form fields, annotations, and layers into static page content in your browser so portals that choke on interactive PDFs still accept the file — without uploading filled forms to a flatten SaaS.
How to use Flatten PDF
- 1Drop the interactive or annotated PDF.
- 2Run flatten locally.
- 3Confirm fields look correct as static ink.
- 4Download and submit. Keep an unflattened master if you still need editable fields.
Frequently asked questions
Can I edit fields after flatten?
No. Flattening is one-way for interactivity. Keep a pre-flatten copy.
Signatures and comments?
They become part of the page appearance. Verify critical marks before discarding the original.
File size?
Sometimes increases slightly. Compress PDF afterward if needed.
Why do portals demand flatten?
Many government/HR uploaders only render static content and mishandle AcroForm fields.
Redaction first?
Redact sensitive values before sharing flattened exports outside your org.
