A passport-size photo isn't just any selfie — it has a specific shape, head height and, for online uploads, a small file size. Get any of those wrong and the application bounces. Here's how to turn a normal photo into a compliant passport photo in under a minute, and the rules that actually matter.
Passport photo basics
Printed passport photos are most often 35×45 mm (3.5×4.5 cm) worldwide, or 2×2 inches (51×51 mm) for the US. For online portals you upload a digital file instead — commonly around 200×230 to 600×600 pixels and under 50KB — showing a clear, front-facing photo with a plain light background and your face centred. The US Department of State specifies a 600×600 px image with the head measuring 25–35 mm from chin to crown.
Resize it in three steps
- Open the right tool — the general Passport Photo Resize, or the exact 35×45 mm or 2×2 inch version.
- Upload a front-facing photo; it's cropped to the passport ratio so your head is framed correctly.
- If your portal caps the file size, compress to the required KB, then download the ready-to-upload file.
Tips for an accepted photo
- Use a plain, light background with even lighting
- Face the camera directly with a neutral expression
- Leave a little space around your head so the crop looks natural
- Always confirm the exact size your specific portal requires
Frequently asked questions

- 35×45 mm (about 413×531 px) is the international standard used by India, the UK, the EU and most countries. The US uses a 2×2 inch (600×600 px) square photo.
- Can I take a passport photo at home and resize it online?
- Yes. Take a front-facing photo against a plain light wall with even lighting, then crop it to the passport ratio with a passport photo tool and compress to the required size. Make sure the head height and background also meet the rules.

- Many portals cap it around 50KB; US digital photos run larger (54KB–10MB at 600×600). Check your portal and compress to its limit.
