All tools
Every tool follows one path: make a mark, or capture one you already have, put it on the document — then organise the PDF around it. Nothing you open here is uploaded — every file is processed in your own browser.
Design a mark
Start from scratch, from a prompt, or from a regional template.
- Seal generatorDesign a round, oval or square seal with full control over text, fonts, borders and ink texture. Export PNG, SVG, PDF or DOCX.Open
- AI stamp generatorDescribe your stamp in plain words and get an editable vector seal in seconds. Free to try, export PNG / PDF / DOCX / SVG.Open
- Template galleryReady-made seals for Chinese, Japanese, Korean and Western conventions. Pick one and the whole style loads into the editor.Open
Capture one you have
Turn a handwritten signature or a stamped sheet of paper into a clean, transparent file.
Put it on a document
Place marks on PDF and Word files, and reshape the pages around them.

- Word stampingPlace a seal on any page of a Word document in the browser. Import DOCX, position the stamp, export — nothing is uploaded.Open
- Verify a sealCheck whether a seal's main text and anti-counterfeit code were registered here. No company data is ever stored.Open
Organise PDF pages
Merge, split, rotate, number and watermark PDFs. Each task has its own page; all of them open the same workspace.
