The Precise 400x514 Pixel Metric
Singapore's ICA (Immigration & Checkpoints Authority) operates one of the most technologically advanced digital portals in the world. They demand an incredibly specific digital file: exactly 400 pixels wide by 514 pixels high.
File Size and Format
The image must be in JPEG format and the file size must not exceed 60 KB. This requires aggressive but intelligent compression to ensure the facial biometrics remain sharp while discarding unnecessary data.
The Matte Finish Lighting Rule
The ICA specifically warns against uneven lighting and flash reflections on the skin. Your face must have a matte appearance. If you have oily skin that reflects the camera flash, the validator may flag the photo. Ensure you use diffused, natural window lighting.
