Ireland passport photo size & rules
Ireland uses the 35x45mm photo format, equal to 413x531 pixels at 300 dpi. A key feature of the Irish system is Passport Online, where most applicants upload a digital photo rather than sending prints; the online tool checks that the head from chin to crown measures between 29mm and 34mm, similar to the UK, with the face centred in the frame. Photos where the head is too large or too small are the most common reason the Irish online checker rejects an image.
The background must be plain and light, either light grey or white, with even lighting and no shadows behind the head. Face the camera directly with a neutral expression and mouth closed, both eyes open and clearly visible, and nothing covering the face or eyes. When you apply through Passport Online you enter a code from your printed photo or upload a digital file that meets the size and quality rules. Glasses are best removed to avoid glare, and head coverings are only accepted for religious or medical reasons, with the full face remaining visible.
Pixohub sizes your Irish passport photo to 413x531 pixels in the browser, with the image never leaving your device, giving you real privacy for your ID photo, and it is free to use. The Department of Foreign Affairs updates the Passport Online photo rules and the automated checker periodically, and the acceptance thresholds can be strict. Always confirm the current requirements on dfa.ie before you upload or print so your application passes on the first attempt.
