How to Prepare a Passport or Visa Photo for Online Upload

Online passport and visa applications reject photos automatically: too small, too large, the wrong shape, the wrong format. The frustrating part is that the face and background can be perfect and the upload still fails on a technical rule. This guide covers the technical side — size, shape and file weight — for two common portals, and shows how to meet them.

Passport photo size in pixels Crop to a ratio Compress to 100 KB

What resizing can and can’t fix

Resizing and compressing fix technical rules only. They cannot fix a shadow on the wall, a tilted head, glare on glasses or a busy background — for those, retake the photo. Always follow the official guidance of the country you are applying to.

Two common examples

	US visa (DS-160)	UK passport (online)
Format	JPEG	JPEG (other types may be accepted — check the portal)
Shape and size	Square, between 600 × 600 and 1200 × 1200 px	At least 600 px wide and 750 px high
File size	Up to 240 KB	Between 50 KB and 10 MB
Other rules, for example	Colour photo; head about 50–69% of the image height	Plain light background; taken recently

Other countries differ — printed EU and Schengen-style photos are 35 × 45 mm, which is 413 × 531 pixels at 300 DPI. Treat the figures above as examples, and check the official page before you upload.

Step by step

Take a good photo first. Daylight facing a window, a plain light wall, a neutral expression, no filters or beauty modes. Ask someone to take it, with the camera at eye level.
Crop to the right shape. For a square requirement, use the crop tool with the Square ratio; for a 35 × 45 mm shape, enter a custom ratio of 35 : 45. Position the head as the official guidance describes.
Set the exact pixels. Open the passport photo size page for 413 × 531, or type the width and height your portal states.
Set the file size. Switch on the maximum file size and enter the limit — for example 240 KB. The tool finds the highest quality that fits under it.
Check, then upload. Drag the before/after slider to look for blur, and confirm the file is a JPEG within the limit.

Common reasons uploads are rejected

A stretched image. Dragging a photo into shape changes its proportions. Crop instead, and let the resize keep the aspect ratio.
Too small after cropping. Cropping tightly from a small original can push the pixel count below the minimum. Start from a larger picture.
The wrong format. iPhone photos are usually HEIC, which many portals refuse — convert it to JPG first.
Filters or edits. Portals often check for alteration. Use the plain, unedited photo.

A note on privacy

A passport photo is among the most sensitive images you own, and some online resizers upload it to their servers to process it. CrispPic does everything in your browser, so the photo is never sent anywhere — which is why it suits ID photos.

Frequently asked questions

What size is a passport photo in pixels?

A standard 35 × 45 mm print at 300 DPI is 413 × 531 pixels. But each online portal sets its own pixel rules, so use the numbers on the portal’s own instructions.

Can I use a photo taken on my phone?

Usually yes, provided it meets the portal’s rules. If it is an iPhone photo in HEIC format, convert it to JPG first.

My photo is under the 50 KB minimum. What now?

Don’t compress it further. Use the original size, or set a higher maximum file size so the result stays above the minimum.

Can this tool change the background or fix the lighting?

No. CrispPic resizes, crops and compresses. Background, lighting and pose have to be right in the photo you start with.
