🎓 WiMailer

Create, Customize, Send Certificates Effortlessly

✨ What is WiMailer?

WiMailer is a simple, powerful tool that runs entirely in your browser. It lets you create professional-looking certificates for any number of people using just two things: a picture (your certificate design) and an Excel file (your participants' details). Then, with a single click, you can email each person their personalized certificate as a high-quality image attachment.

Whether you're organizing a workshop, a course, a competition, or a training program, WiMailer saves you hours of manual work. No design skills, no coding knowledge, and no complicated software installation is required – just use your web browser.

🛠️ Features That Make Your Life Easier

🖼️ Drag-and-Drop Certificate Canvas

Upload any PNG, JPG, or WebP image to use as your certificate background. Then simply drag and drop text fields anywhere on the image – just like arranging stickers on a photo.

📊 Excel / CSV Import

Use your existing participant list from Excel or CSV. Every column in your spreadsheet automatically becomes a draggable text field (like "Name," "Course," "Date"). Supports .xlsx, .xls, and .csv files.

🎨 Rich Typography Options

Choose from 20+ different fonts from handwritten to formal serif. Control size, color, bold, italic, text alignment, and even add a professional drop shadow to make your certificates stand out.

👁️ Per-Row Adjustment

Click on any row in your data table to preview how that specific recipient's certificate will look. Fine-tune the font or position just for that person without affecting the others – perfect for fixing long names.

📦 Bulk Download as ZIP

Generate all certificates at once and download them in a single ZIP file. A live progress bar shows you exactly how much is done – even for hundreds of participants.

📧 SMTP Email Delivery

Send each certificate directly as a PNG attachment to its recipient's email address using your own SMTP server. Everything stays private and secure – you are in full control.

🎯 How It Works – Three Simple Steps

Upload Your Certificate Design – This is just a regular picture of your certificate template without any names or details on it. Ideally, leave blank space in the middle for names.
Upload Your Participant List – This is an Excel or CSV file that has one column for each piece of information you want to appear on the certificate. For example: Name in column A, Course in column B, and Email in column C.
Position, Preview, and Generate – Drag each column onto your certificate image to define where it appears. Check your work with the preview. Then click "Generate All" to create every certificate in seconds. You can download them or email them instantly.
