About this app

Just type a name and your seal is ready.

The seal you make can be pressed straight onto PDF and image documents and saved. For contracts, quotations, and application forms that have a space for a seal, there is no need to print the page, stamp it, and scan it back in.


[ Three ways to make a seal ]

Create from text
Enter a personal name or a company name and the characters are laid out to fit the seal. Up to 12 characters can be engraved, and Korean letters can be converted into Chinese characters before they are carved.

Photograph a real seal
Take a photo of a seal you pressed on paper and the background is removed to leave a transparent image. Drag the four corners to straighten a tilted photo, wipe away small blotches, and either keep the original color or change it to the color you want.

Draw a signature
Draw your signature with a finger or a stylus. Pen thickness is adjustable, and you can let strokes thin out as you draw faster so the handwritten feel stays.


[ Shape it the way you want ]

· Border shape : Circle, Ellipse, Square, Rectangle, Gourd
· Fonts : Seal script, Clerical script, Regular script, System serif and System sans
· Colors : Seal red, Black, Blue, Purple, Teal presets, plus any color you pick yourself
· Character size, letter spacing, layout, and border thickness
· Ink texture : texture strength, Edge bleed, Ink break, and a slight tilt as if pressed by hand

What you see on screen is exactly what gets saved. The preview and the finished file never drift apart.


[ Stamp documents directly ]

Open a PDF or an image document and drop the seal where you want it. Documents with many pages can be stamped page by page, and a date can be placed next to the seal. A saved document can be shared right away.


[ Export ]

· Set the real size in mm and save at 300DPI or 600DPI
· Transparent or White background
· PNG or JPG
· Save to gallery, Copy to clipboard, or share to another app
· No watermark is added


[ Also worth knowing ]

· One notification per day, at a time you choose. It can be turned off whenever you like.
· Pick a light or a dark screen, or leave it following the system setting.


[ Everything is processed on your device ]

Making a seal and stamping it onto a document both finish inside your device. The name you type, the seal image that is created, and the documents you open are not sent to a server. The network is used only to show ads.
