Key facts

Passport Size Photo Resize is a Documently preset that turns any photo into a 3.5 × 4.5 cm passport-style JPG of 413 × 531 pixels at 300 DPI, with a 100 KB maximum. The arithmetic: 3.5 cm ÷ 2.54 × 300 = 413 px, and 4.5 cm ÷ 2.54 × 300 = 531 px. At 200 DPI the same print size is 276 × 354 px, which is why forms quote different pixel sizes for one photo. In our tests, a 5.6 MB phone photo came out at 413 × 531 px, 300 DPI and 54 KB. No single passport photo KB size exists; each form sets a range, such as 20–50 KB for IBPS PO 2026, so the Min size and Max size fields are editable. The photo is centre-cropped, never stretched, and processed in the browser without upload. Passport Seva and visa portals publish their own rules. Set the KB range from your form, then tap Resize.

Most Indian application forms ask for a passport-size photo, and the shape they mean is commonly 3.5 × 4.5 cm. Online, that size has to be expressed in pixels and kilobytes. This page is preset to 413 × 531 px at 300 DPI with a 100 KB maximum, and you can change the KB limits to match your form. The photo is processed on your phone, never uploaded.

How 3.5 × 4.5 cm becomes 413 × 531 pixels

Pixels depend on DPI (dots per inch). One inch is 2.54 cm, so 3.5 cm is 1.378 inches and 4.5 cm is 1.772 inches. At 300 DPI that works out to 413 × 531 pixels.

At 200 DPI the same photo would be 276 × 354 pixels — still 3.5 × 4.5 cm when printed at 200 DPI. That's why some forms quote different pixel sizes for the same physical photo. If your form gives exact pixels, type those in; switch Units to Centimetres if it gives cm.

Every form sets its own KB limit

There's no single 'passport photo size in KB'. One form may want 20–50 KB, another up to 200 KB. This preset starts with a 100 KB maximum. Change Max size and Min size to whatever your form says.

If the photo ends up too small, the tool safely pads the file up to the minimum without changing the picture. If it's too big, JPEG quality is lowered just enough to fit.

Passport, visa and exam photos aren't all the same

Indian passport-style photos are commonly 3.5 × 4.5 cm, but the Passport Seva portal, visa applications and exam boards each publish their own rules for size, background and face position. Some visas use completely different dimensions. Always check the instructions on your form before you upload.

For major exams, use the exam photo tool — it's preset to each verified notification.

Tips for a photo that won't be rejected

  • Plain white or light background, no patterns or shadows behind you.
  • Face the camera straight with your shoulders level; both ears visible.
  • Light from the front — stand facing a window rather than with it behind you.
  • Head and top of shoulders in frame. If the original is wide, turn off Keep proportions: the photo is centre-cropped to the passport shape, never stretched. Use Crop Image first if you want to choose the crop yourself.
  • No caps or dark glasses unless the form allows them.

Frequently asked questions

What is passport size photo size in pixels?

A 3.5 × 4.5 cm passport-size photo is 413 × 531 pixels at 300 DPI, or 276 × 354 pixels at 200 DPI. Both print at the same physical size. Use whichever pixel size your form asks for; this tool saves the DPI in the JPG.

What is passport size photo size in KB?

There's no fixed KB size — each form sets its own range, such as 20–50 KB or up to 200 KB. Type your form's minimum and maximum into the Min size and Max size fields and the tool keeps the JPG inside that range.

Will resizing to passport size stretch my face?

No. If your original has a different shape and Keep proportions is off, the photo is centre-cropped to 3.5 × 4.5 cm, never stretched or squashed. For control over the crop, use Crop Image with the Passport 3.5:4.5 shape first.

Is this the size for the Passport Seva portal?

Indian passport-style photos are commonly 3.5 × 4.5 cm, but Passport Seva and visa applications publish their own photo rules, which can differ. Check the instructions on the portal you're applying through and set the pixels and KB to match.

Can I make a passport photo on my phone without uploading it?

Yes. Everything happens in your browser. Pick the photo from your gallery, resize, and download — the image never leaves your phone. iPhone HEIC photos aren't supported yet; use Most Compatible camera format or a screenshot.
