Government passport renewal and travel visa portals are notoriously strict. If your photo exceeds 100KB, the submission is rejected. If it looks blurry or over-compressed, your visa application can be delayed for weeks. Here is how to format and compress your passport photo correctly.

Official Passport Photo Specifications

Most nations mandate standard headshot dimensions: 2x2 inches (600x600 px at 300 DPI) in the United States, or 35x45mm (approx 413x531 px) across Europe and Commonwealth countries. Your head should occupy between 50% and 70% of the vertical frame.

Framing & Background First

Before compressing, use our [Image Cropper](/tools/image-cropper/) to frame your face centered against a plain white background. Cropping away unnecessary shoulder area removes unneeded pixels before compression.

Compressing to Under 100KB

Open [Compress Passport Photo to 100KB](/compress-passport-photo-to-100kb/). Upload your cropped photo. The tool preserves facial details, contrast, and eye contours while optimizing file size to roughly 90KB–98KB.

Common Reasons Passport Photos Are Rejected

- File size exceeds portal limit (e.g. 104KB when 100KB was specified) - Harsh shadows or colored backgrounds - Over-compression creating artifacting around the eyes or nose - Head tilted or looking away from camera
