How to Make a Passport Size Photo on Mobile (Full Step-by-Step Guide)

Published on 28 September 2026 • SmartWish Team

Almost every government recruitment exam, college admission form, visa application and official document now uses an online portal, and nearly all of them ask for a standard passport size photo.

Many candidates end up visiting a photo studio or cyber cafe just to get the right pixel size, or they upload an unedited phone camera image and have their form rejected. This guide shows how to take and resize a proper passport size photo directly from your mobile phone in a couple of minutes without losing clarity.

1. Standard Passport Photo Sizes

Passport photo dimensions vary slightly between countries and individual examination boards. The table below lists the most widely requested sizes.

Format / Country Size in mm Size in cm Pixels at 300 DPI
India (standard passport & exams) 35 mm × 45 mm 3.5 cm × 4.5 cm 413 × 531 px
SSC / Banking / State portals 35 mm × 45 mm (or 200 × 230 px) 3.5 cm × 4.5 cm 413 × 531 px (or 200 × 230 px)
United States / US Visa 51 mm × 51 mm (2" × 2") 5.1 cm × 5.1 cm 600 × 600 px
UK / Schengen / Australia 35 mm × 45 mm 3.5 cm × 4.5 cm 413 × 531 px
Requirements are set by each issuing authority and can change from year to year. Always confirm the exact dimensions and KB limit stated in the official instructions of the form you are filling before uploading.

2. How to Take a Good Passport Photo with Your Phone

Getting the pixel numbers right is only half the job. Online portals also check whether the photo looks like a formal identification portrait. Follow these mobile photography tips:

  • Use the rear camera if possible: Front selfie cameras taken at arm's length can distort facial proportions (making the nose look larger and ears less visible). Ask someone to take the photo from about 1.5 metres away, or use a timer.
  • Stand in front of a plain light wall: A plain white, off-white or very light grey wall works best. Stand a small step away from the wall to avoid dark shadows behind your head.
  • Face the light source: Stand facing a window or room light so both sides of your face are evenly lit.
  • Keep your head straight: Look directly into the camera lens with both ears visible, eyes open and a natural, neutral expression.
  • Avoid glasses glare and headwear: Remove caps, sunglasses or tinted lenses. If you wear prescription glasses, make sure there is no flash reflection on the lenses.

3. How to Crop and Resize the Photo on Mobile, Step by Step

Because mobile phone cameras capture tall rectangular photos (such as 3:4 or 9:16), resizing a full photo directly without cropping first can make your face look squished. Follow these steps for a properly proportioned result:

  1. Crop around your head and shoulders first: Open our Photo Editor (or your phone gallery crop tool) and crop the photo so your head and upper shoulders fill the frame, leaving a small margin above your hair.
  2. Open the SmartWish Passport Photo Tool in your mobile browser.
  3. Tap the upload box and select your cropped photo.
  4. Set the Unit selector to Millimeters (mm) (or keep Pixels if you prefer entering 413 × 531 directly).
  5. Turn off Lock aspect ratio so both width and height can be entered exactly.
  6. Enter a width of 35 and a height of 45 (or 413 and 531 in pixels).
  7. Set DPI to 300 so the photo has full resolution for printing and online portals.
  8. If your exam or application form asks for a 20KB to 50KB file size, type your target (for example, 35 or 45) into the Target size in KB box.
  9. Tap Resize Now, inspect the preview and final file size, then tap Download Image.

At 300 DPI, a 35 mm × 45 mm setting automatically produces a 413 × 531 pixel JPG, which matches standard Indian passport and recruitment portal requirements.

4. Keeping the Photo Sharp Under a 20KB or 50KB Limit

A JPG file needs enough data per pixel to keep facial details crisp. If you apply a 20KB limit while the image is still 3000 × 4000 pixels straight from your phone camera, the compressor has to discard heavy detail and the face turns blurry or blocky.

When you resize the photo to 413 × 531 pixels first and then apply a 20KB–50KB limit, the file has far fewer pixels to encode, so your face remains sharp and clear.

5. Frequently Asked Questions

What background should a passport size photo have?

A plain, evenly lit background works best. Plain white is the most widely accepted across passport, visa and exam portals, while light grey or light blue is permitted on some forms. Avoid curtains, outdoor backgrounds, patterns and harsh wall shadows.

Should I sign or write a date on the photo?

Only if the official notification specifically asks for it. Certain entrance exams ask for the candidate's name and the date of photograph printed below the face, whereas passport, PAN and visa applications strictly require a plain photo with no text written on it.

What DPI should a passport photo use?

300 DPI is the standard for both photo printing and digital submission. At 300 DPI, a 35 mm × 45 mm photo equals 413 × 531 pixels. You can learn more in our guide on what DPI means and how to change it.

Can I use a photo received on WhatsApp?

You can, but WhatsApp compresses photos automatically when sent as normal chat images, which lowers sharpness. Whenever possible, use the original photo from your phone's camera folder or share it on WhatsApp as a Document to preserve full quality.

Why does my passport photo look blurry after compression?

Blur usually happens when a small KB target (like 20KB) is applied to a high-resolution camera image before resizing its pixel dimensions. Always set the dimensions to 413 × 531 pixels first and then apply the KB target.

Is my photo uploaded to a server?

No. All cropping, resizing and KB compression happen locally inside your mobile browser using the HTML5 Canvas API, so your personal photo never leaves your phone. Read our Privacy Policy for complete details.
