OPTIMIZE TOOL
Flatten PDF
Merge all interactive AcroForm text fields, checkboxes, dropdowns, and digital annotations permanently into the PDF page canvas. Flattening makes forms non-editable, ensuring compliance with government submissions, legal e-filings, and archival standards.
FAQ
Frequently asked questions
Why do government and court portals require flattened PDFs?
Government and visa portals often reject interactive forms because form fields can accidentally shift, disappear, or be altered after submission. Flattening locks all text permanently in place.
Can someone edit the form fields after flattening?
No. Flattening permanently transforms interactive form fields into static vector and raster elements on the page.
Does flattening reduce PDF file size?
Often yes. Removing interactive form dictionaries and unneeded widget metadata typically streamlines document file size.
