Frequently Asked Questions

Everything you need to know about using CertGen to generate certificates in bulk.

How do I generate certificates in bulk?

Upload a PNG or JPEG certificate template, then add recipient data from a CSV, Excel, or public Google Sheets file. Place fields such as name, course, date, or score on the template, preview the result, and download the batch as a ZIP. The entire process takes under a minute for most batches.

Is this certificate generator free?

Yes — completely free. There is no account, no watermark added to your certificates, and no limit on how many certificates you generate. Your files are deleted automatically after download.

Can I make certificates from an Excel or CSV file?

Yes. Upload a CSV or XLSX file with column names in the first row. CertGen detects those headers so you can select them when positioning text on the certificate image.

Can I use Google Sheets for certificate generation?

Yes. Paste the URL of a publicly accessible Google Sheet. Its header row and recipient data become available for field mapping in the same way as an uploaded spreadsheet.

Which certificate output formats are supported?

Choose PNG, JPG, or PDF output for the generated certificates. All files are combined into a single ZIP download for straightforward distribution or email attachment.

Do I need to install any software?

No. CertGen is a fully browser-based, free online certificate generator. Nothing to install. Upload your files, design your layout, and download your certificates from any device.

Can I use custom fonts on my certificates?

Yes. Paste any Google Fonts CSS URL to apply a custom typeface to individual fields or across the entire batch. Font style is set per-tag, giving you fine-grained typographic control.

How many certificates can I generate at once?

There is no hard limit. CertGen processes records concurrently with parallel workers, so large batches (hundreds of recipients) still complete in seconds. Sessions remain active for 15 minutes after upload.

How to Generate Certificates in Bulk

Four steps from template to finished ZIP — no design software, no coding, no account required.
