About this tool
Looks the same everywhere
Each field and annotation is drawn using its own appearance, so what you see is what everyone sees, even in readers that don't support forms.
Links keep working
Links aren't flattened. Hidden annotations are removed rather than drawn.
Frequently asked questions
Can I edit the form after flattening?
No. Keep the original if you might need to change values.
Why flatten before signing or sending?
It prevents the recipient from changing filled-in values, and avoids forms that look different from one reader to another.
Is my file uploaded?
No. It's processed in your browser and never leaves your device.
