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.
