Why this stamp maker
Browser-only, zero uploads
Editing, rendering and exporting all happen on your device. Your text never leaves the browser, and the tool keeps working offline after fonts load.
Professional curved text
Top text follows the arc, bottom text stays upright, with adjustable spacing — plus stamp-grade fonts for English and Chinese.
Realistic aging effect
A tunable filter adds rough edges and missing ink, turning a clean vector circle into something that looks actually stamped.
Every format you need
PNG in three resolutions, white-background JPG, editable SVG vectors, a PDF sized in millimeters, or everything in one ZIP.
FAQ
Is this stamp maker really free?
Yes — no watermarks, no signup, no export limits. The site is supported by ads.
Are my designs uploaded anywhere?
No. All processing happens in your browser, and autosave lives in your browser localStorage. Reset clears it anytime.
Is the exported PDF print-accurate?
The PDF page equals your millimeter size (e.g. 40×40mm) with a 10× raster (300+ DPI) filling it, so printing gives the exact physical size.
Can I use it for official documents?
This tool is for mockups, templates, teaching materials, packaging and personal projects. Legal company seals must be produced under local regulations — do not use generated artwork to forge or misrepresent official stamps.
Why does exporting need internet?
Before exporting, the fonts you used are subset-embedded from Google Fonts. Preview works offline after the first load; exports fall back to system fonts if offline.
