Flatten PDFs Online

Use our free Flatten PDF tool to merge all elements—such as text fields, images, and annotations—into a single, uneditable layer. Perfect for finalizing forms, securing signatures, and preparing documents for official use or archiving.

What Does Flattening a PDF Mean?

Flattening a PDF converts interactive and layered content (like form fields, annotations, and digital signatures) into a standard, non-editable layer. It ensures that what you see on-screen is exactly what others will see or print—no hidden elements, and no interactive features.

Why Flatten a PDF?

• Preserve Layout: Prevents changes in form design or positioning.
• Protect Data: Secures filled form fields and annotations from editing.
• Reduce File Size: Removes unnecessary scripts and interactive layers.
• Ensure Compatibility: Improves viewing and printing across devices and platforms.

Common Use Cases

• Submitting finalized application forms
• Securing signed contracts
• Archiving legal documents
• Sharing read-only design drafts

Flattening vs. Locking PDF

While both prevent edits, flattening visually merges content into a single layer, making it completely uneditable. Locking, on the other hand, can often be reversed or bypassed. Flattening is the most secure and final method of protecting the contents of a PDF.

Conclusion

If you want your PDF content to stay exactly as it is—visible, printable, but unchangeable—flattening is the right choice. Use our Flatten PDF tool today to secure your documents for good.
