How to resize a photo to passport size
Upload your photo and select the target size. The tool crops the largest centred area with the right proportions and resizes it to the exact pixel dimensions for 300 DPI. You can zoom in from 100 to 200 percent to make the head larger in the frame. Download a single JPG, or switch to Print sheet for copies on a 6×4 in page.
If the photo already has a plain background, leave it as it is. If not, pick white, light grey, light blue or a custom colour; selecting a colour turns on Replace the background behind me and puts the subject on that colour.
Passport photo sizes in pixels
At 300 DPI, 35×45 mm is 413×531 pixels, used here for India, UK and Schengen presets. US 2×2 in is 600×600 pixels. Canada 50×70 mm is 591×827 pixels, and China visa 33×48 mm is 390×567 pixels. The DPI value tells printers how large to print the image, so a 413×531 pixel file at 300 DPI prints at 35×45 mm when you print at actual size.
Online applications often have their own pixel and file size requirements that differ from print sizes. Some ask for a larger image, a different shape or a maximum number of kilobytes. Check the portal's instructions, and use the compressor or resizer tools if you need a different file size.
Resizing tips
Start from the largest, sharpest version of your photo. Resizing a small image up to 600×600 pixels will not add detail, and blurry passport photos are often rejected. Avoid screenshots of photos, which lose resolution.
Because the crop is centred and cannot be moved, a photo where the face is well off-centre may crop badly. In that case retake it with the face in the middle. When printing, choose actual size or 100 percent in the print dialog rather than fit to page, then measure the result with a ruler. This tool does not verify that the photo meets passport rules, so check your authority's current requirements.
