A stamp maker is a free online tool that turns your text into a custom rubber stamp image. Instead of ordering a physical self-inking stamp, you type your wording, pick a round or rectangular shape, choose an ink color, and instantly get a digital stamp you can place on documents, invoices, photos, and PDFs. Everything is generated in your browser using HTML canvas, so your text never leaves your device and there is no watermark.
Click Create Stamp to open the editor, then choose between a round seal or a rectangular stamp. Enter your top, main, and bottom text, where the top and bottom lines curve around a round stamp automatically. Select an ink color from the presets or pick any custom color, set the border to single, double, or dashed, and adjust the distress slider to add a worn, used-stamp look. You can also rotate the stamp for a hand-stamped feel and add today's date for received or paid stamps.
Round stamps work best for official seals, company logos, notary marks, and approval seals where curved text wraps around a central word like APPROVED or PAID. Rectangular stamps suit straightforward office marks such as RECEIVED, CONFIDENTIAL, DRAFT, and URGENT, where text sits in clean horizontal lines. This tool supports both, with star separators and inner divider lines so you can match the classic look of professional rubber stamps.
Download your stamp as a transparent PNG so it sits cleanly over any document, contract, or scanned page without a white box around it. The checkerboard preview shows exactly which areas stay see-through. Prefer a flat file instead? Switch the background to a solid color, or export as JPG or WebP. The image is rendered at your chosen output size up to 1000 by 1000 pixels, so it stays sharp when printed or placed at a large scale.
Use the stamp maker for approval and rejection marks on paperwork, paid and received stamps for accounting, confidential or draft labels on internal documents, quality assurance and inspection seals, event and loyalty stamps, and decorative seals for invitations and certificates. Because the distress effect mimics real ink on paper, the stamps look authentic when overlaid on photographs or applied digitally in a PDF editor.
