About Us

A4 Print Size exists to solve one frustrating problem: getting photos to print at the exact physical size — every time, without guesswork, without expensive software, and without sending your personal photos to a server.

What We Do

A4 Print Size is a free online toolkit for photographers, studios, passport-photo centers, students, and anyone who has ever fought with print dimensions. With our tools you can:

• Set a photo to exact millimeters, centimeters, or inches;
• Generate a print-ready A4 sheet with multiple copies, automatic packing, and cutting crop marks;
• Apply common passport and visa photo presets for 10+ countries;
• Convert PDFs to high-resolution images, and images to PDF;
• Check effective DPI and print quality before you hit print.

Our Mission

Printing should be precise and private. Our mission is to make professional-grade photo layout accessible to everyone — free of charge, with no account required, and with a privacy model that is easy to understand:uploaded photos are processed locally in your browser and are not sent to our servers. Every crop, resize, layout, and PDF render happens in your browser's memory using 100% client-side code.

Why Trust Us

• Privacy by design. Zero-server architecture means no uploads, no accounts, and nothing stored on our side.
• Precision. Physical scaling is computed at true millimeter level and exported as print-ready 300 DPI raster images in a dimensionally accurate PDF.
• Currently free. The tools are free for personal and commercial use, with no hidden fees.
• Standards-based. Our presets are based on commonly published government and ISO print specifications.

Our Values

We believe good tools are fast, precise, and respect the user. That means no upload queues, no watermarks, no account walls, and no dark patterns. If a tool can be built to run locally, it should run locally.
