Flatten PDF
Lock fillable form fields permanently into your PDF — filled-in text becomes part of the page and cannot be edited again. Your file never leaves your device; everything runs locally in the browser.

Privacy note: Your file never leaves your browser — all work happens on your phone/computer, nothing is uploaded.
How to use
- Click the box above or drag and drop your filled PDF form into it — the field count will appear.
- Click Flatten & Download PDF.
- In the downloaded copy, the fields will be permanent. If the PDF has no form fields at all, the tool will give you a clean re-saved (normalized) copy and will clearly tell you so.
Tips
- Always keep a copy of the original fillable PDF before flattening — you cannot undo it.
- If your PDF has no form fields, the tool simply returns a clean re-saved copy.
- Flatten before sharing contracts or applications so recipients see exactly what you entered.
Frequently Asked Questions (FAQ)
What does Flatten PDF do?
It turns fillable form fields into permanent page content, so the filled-in text becomes part of the page and cannot be edited again.
What if my PDF has no form fields?
The tool gives you a clean re-saved normalized copy and clearly tells you so.
Is my PDF uploaded anywhere?
No; your file never leaves your browser. All work happens on your device, with no signup.
Can I flatten multiple PDFs at once?
No; the tool works on one PDF file at a time, so flatten each file separately.
