How to resize a photo

1. Choose the Unit and type the Width and Height in the settings panel. Set one of them to 0 to keep the photo’s proportions.
2. For centimeters, millimeters or inches, choose the DPI the form asks for (300 if it doesn’t say).
3. Choose photos or drop them on the page. Each is resized right away and saved as a JPG named with its new size, such as photo-600x800.jpg.
4. Press Save or Download. Changed a setting? Press Apply to all files.

What the settings do

• Unit: Pixels, Centimetres, Millimetres or Inches.
• Width and Height: the size you want. Width is 600 and height 0 by default, so photos become 600 pixels wide with the height worked out for you.
• DPI: 96, 200, 300 or 600. It converts physical sizes to pixels and is written into the JPG so printers know the intended size.
• When both sizes are set: Use exactly this size stretches the photo to fit; Fill and crop fills the size and trims what sticks out; Fit inside, white edges keeps the whole photo and adds white bands.
• File size limit: No limit, or under 20, 50, 100 or 200 KB. The pixel size stays fixed and only the JPEG quality goes down.

Converting centimeters and inches to pixels

Pixels = inches × DPI, and an inch is 2.54 cm. At 300 DPI, 3.5 × 4.5 cm is 413 × 531 pixels, and 2 × 2 inches is 600 × 600 pixels. The tool does this math for you; just type the size in the unit the form uses.

Which DPI? 300 is the usual standard for printed photos and what most forms mean when they give a size in centimeters. 600 is for very fine printing. 96 and 200 give fewer pixels and smaller files, useful when a form sets both a physical size and a tight KB limit.

Common problems and fixes

• The photo looks squashed: you set both sizes with Use exactly this size. Choose Fill and crop or Fit inside, white edges instead.
• “Can’t get under N KB”: at that pixel size the photo can’t get small enough. Lower the dimensions or choose a higher limit.
• “That size is too big”: each side must stay under 12,000 pixels. Check the unit and DPI.
• An enlarged photo looks blurry: making a small photo bigger can’t add detail. Start from the original, full-size photo.

Tips

• For passport and visa photos, Passport photo maker crops your face to the right shape and makes a print sheet.
• If you only need a smaller file, not exact dimensions, use Compress image.
• The result is always a JPG, and any transparent areas become white.
