Flatten PDF Free
Lock form fields, merge annotations, and flatten layers into a single, uneditable PDF — all in your browser.
Flatten PDF NowNo signup. Documents processed in your browser — nothing uploaded.
Flattening a PDF merges form fields, annotations, comments, and layers into a single flat document. The content becomes part of the page — it cannot be edited, moved, or extracted. fileGOD flattens your PDF entirely in your browser using pdf-lib, so your document is never uploaded to any server. Ideal for finalizing forms, locking signatures, and preparing documents for archival.
How It Works
Drop your PDF
Drag and drop a PDF with form fields, annotations, or comments into the tool.
Flatten instantly
All interactive elements are merged into the page content. Form fields become static text, annotations become part of the page.
Download the flat PDF
Preview the flattened document and download. All content is permanently locked in place.
Why fileGOD?
Flatten Form Fields
Text fields, checkboxes, dropdowns, and radio buttons become static content. Values are preserved, but fields are no longer editable.
Merge Annotations
Comments, highlights, sticky notes, and markup become part of the page. They cannot be modified or deleted.
Lock Signatures
Digital signature fields are flattened into the page. The visual appearance is preserved.
Reduce File Size
Flattened PDFs are often smaller because interactive element metadata is removed.
100% Client-Side
Your document is processed in your browser using pdf-lib. No file is uploaded to any server.
Preserves Layout
Page layout, fonts, images, and formatting remain exactly as they appeared before flattening.
