Does the certificate generator upload anything to a server?

No. Everything runs inside your browser using the HTML5 Canvas API and jsPDF. No text, images, or data ever leave your device.

What PDF size does it produce?

The downloaded PDF is A4 — either 297×210 mm (landscape) or 210×297 mm (portrait). The certificate image is rendered at twice the screen resolution before embedding, so it prints crisply.

Can I print the certificate directly from the browser?

Yes. Download the PDF and open it in any PDF viewer, then print. For best results set your printer to the same orientation (landscape or portrait) as the certificate.

Is there a limit to how many certificates I can make?

No limit. The tool is free and runs offline in your browser, so you can generate as many certificates as you need without any account or subscription.

Can I add a logo or image to the certificate?

The current version uses canvas-drawn decorative elements only. Logo upload is not yet supported, but you can open the downloaded PDF in any editor (Adobe Acrobat, LibreOffice Draw, etc.) to add additional graphics.

Certificate PDF Generator — Free Online Certificate Maker

What This Tool Does

The Certificate PDF Generator lets you create polished, print-ready certificates entirely in your browser. There is no server involved — the canvas rendering, text layout, and PDF packaging all happen locally using the HTML5 Canvas API and jsPDF.

Six distinct templates cover the most common use cases: a traditional parchment Classic, a clean corporate Modern, a dark-luxury Elegant, a vivid high-contrast Bold, a typographic Minimal, and a formal Academic layout with a seal graphic. Each template adapts to whichever accent color and font style you select.

The downloaded PDF is A4 at full print resolution. The PNG export renders at 2× canvas size, giving you a high-density image suitable for digital display or further editing in any graphics application.

How to Make Your Certificate

Pick a template. Click any thumbnail in the Template panel. The preview updates immediately.

Choose orientation and style. Toggle Landscape or Portrait, select an accent color from the swatches, and pick a font style (Serif, Sans-serif, Monospace, or Cursive).

Fill in the fields. Enter the recipient's name, certificate title, optional subtitle or course name, a short description, issuer name, and date. The canvas redraws as you type.

Download. Click Download PDF for a print-ready A4 PDF, or Download PNG if you need a high-resolution image file.

Print or share. Open the PDF in any viewer and print. For digital distribution simply attach the PDF or PNG to an email or learning platform.

Common Questions

Does this tool upload anything to a server?

No. The certificate is drawn on an HTML5 Canvas element that lives entirely in your browser tab. jsPDF packages the canvas image into a PDF file on your device. Nothing is sent to any server — your recipient's name and any personal details stay completely private.

What paper size and resolution does the PDF use?

The PDF is A4 — 297 × 210 mm in landscape or 210 × 297 mm in portrait. Before embedding, the certificate is rendered on an offscreen canvas at twice the display resolution, so printed output is sharp and clear even on high-DPI printers.

Can I generate certificates in bulk for multiple recipients?

The tool is designed for one certificate at a time. For bulk generation, you would change the recipient name field and click Download PDF for each person. Automated batch processing from a spreadsheet is not currently supported but may be added in a future update.

Is there a limit on how many I can create?

There is no limit. The tool is free, runs locally in your browser, and requires no account or login. You can generate as many certificates as you need.

Can I add my own logo or signature image?

Custom image upload is not supported in this version. All decorative elements are drawn programmatically on the canvas. If you need to add a logo, download the PDF or PNG and edit it in Adobe Acrobat, Canva, LibreOffice Draw, or any image editor before sending.
