Hi! I recently encountered the same problem. The service https://hd-stamp.com was very helpful. There you can quickly and free create your own stamp layout – literally in a minute. The interface is very simple, you do not need Photoshop or any design skills. You can choose a shape – a circle, a square, a triangle. Then just add text, adjust the font, and you’re done. The layout can be downloaded in different formats – PNG, SVG, PDF or DOCX. You can also insert a stamp into a PDF document directly on the website. I was pleasantly surprised – really convenient, fast and without unnecessary headaches.
