The Election Commission allows a more generous file size — up to 2 MB (2048 KB) — so you rarely need aggressive compression. The background must be plain white or a very light solid colour and the face should occupy 70 – 80% of the frame with a neutral expression.
- Size: 35 mm × 45 mm (3.5 cm × 4.5 cm)

What is DPI and why does it matter?
DPI stands for dots per inch — it measures how many pixels are packed into each inch of a printed photo. A higher DPI means sharper prints. Most governments require 300 DPI as the minimum standard for passport photos. At 300 DPI, a 35 mm wide photo contains roughly 413 pixels (35 mm ÷ 25.4 mm/in × 300 ≈ 413 px).
File size in KB is what online portals check when you upload a digital photo. If the file is too large, the portal will reject it. If it is too small, compression artifacts may make the photo unreadable. JPEG quality is the easiest way to control file size — reducing quality from 100% to 85% often halves the KB without visible loss.
Quick formula
Pixels = (mm ÷ 25.4) × DPI
Example: 35 mm at 300 DPI = (35 ÷ 25.4) × 300 ≈ 413 px
KB control tips
1. Resize to exact pixel dimensions first
2. Export JPEG at 80 – 90% quality
3. Use online compressors if still too large

The Indian passport photo size is 3.5 cm × 4.5 cm (width × height). This is equivalent to 35 mm × 45 mm. At 300 DPI the pixel dimensions are 413 × 531 px.
