Adding checkboxes or check marks to a PDF — for completed items, selections, or form responses — is quick using the text insertion tool.
Navigate to PDF Studio and upload your PDF.
Select the Text tool. Click over an existing checkbox printed on the form. Type a check mark character: ✓ (U+2713), ☑ (U+2611), or simply X. Adjust font size to fit within the printed box.
Tip: Copy these symbols directly: ✓ for a simple check mark, ☑ for a checked box symbol. Paste into the text field after clicking the form box location.
Click Download PDF. All check marks are permanently embedded in the output.
The text method places visual check marks. For interactive AcroForm checkboxes, use LibreOffice Writer to create the form.
