6 Precision Checkmark, Cross & Bubble Styles
Every symbol is drawn using pure ISO 32000 vector geometry so it never pixelates when printed or zoomed.
Standard Tick Mark
Ideal when your scanned PDF or tax form already has a printed square `[ ]` and you only need to place a clean tick inside it.
Heavy Bold Checkmark
Designed for low-contrast scans, faxed paperwork, and dense legal checklists where a thicker checkmark stroke stands out clearly.
Cross / X Mark
Required by many government, census, and medical forms that instruct applicants to "Mark with an X" instead of a tick.
Boxed Checkmark
Draws both a crisp outer square border and an inner checkmark—perfect for adding a checked item onto blank PDF margins.
Boxed Cross Mark
Combines a clean white-filled square frame with a centered X mark for structured inspection reports and audit sheets.
Solid Radio Dot
Fills circular radio buttons and multiple-choice survey bubbles cleanly with a solid vector circle.
Vector Checkmark Stamp vs. Interactive AcroForm Checkbox
Our studio supports both permanent vector stamps (default) and clickable AcroForm checkboxes via the toolbar toggle.
| Specification | Flat Vector Stamp (Default) | Interactive AcroForm Checkbox |
|---|---|---|
| PDF Stream Representation | Direct vector path operators (w, m, l, S) | /AcroForm /FT /Btn (/AS /Yes) |
| Can Recipients Uncheck It? | No — permanently locked into the page | Yes — clickable on/off in PDF viewers |
| Font Encoding Dependencies | Zero (drawn geometrically, never fails on WinAnsi) | Uses standard ZapfDingbats / appearance stream |
| Best Use Case | Submitting completed forms, scans, and tax filings | Sending a pre-checked form that others can still toggle |
