Bake supported form-field appearances into PDF pages for a fixed copy. Use Flatten PDF without creating an account. The workbench keeps the source and result together so you can check the output before downloading it.
Flatten PDF covers sharing completed forms, preventing later field edits, and preparing form copies for printing. Its controls stay on one page, with status and validation messages beside the work area.
Compatible files are processed in your browser and are not sent to a PWRKIT processing server. If the input contains sensitive information, follow your organization’s rules for online utilities.
Before using the result, confirm that a PDF containing supported AcroForm fields is complete and that a PDF with form appearances fixed into its pages matches the destination format. Keep the original until you have checked the output in the application or context where it will be used.

What should I check after using Flatten PDF?
Confirm that a PDF with form appearances fixed into its pages matches the intended format and context. Keep the original until the result has been verified.
Flatten PDF draws the current appearances of supported form fields into the page and removes their interactive controls. It does not rasterize the whole document or guarantee removal of comments, attachments, layers, JavaScript, signatures, or other active structures. Fill every field first and confirm that each value is visible. Inspect the new file in another viewer before treating it as a fixed record.
