How to use the Resize Image to 3.5cm x 4.5cm

  1. Choose a photo, or drag it onto the drop area. It stays on your device.
  2. The size is already set to 3.5 × 4.5 cm (413 × 531 pixels). You can switch to a custom pixel size if your form asks for something else.
  3. Drag the crop box over the part of the picture you want to keep. It stays locked to the right shape, so nothing is stretched.
  4. If the form has a file-size limit, type the maximum in KB. The tool lowers JPG quality until the file fits and shows the real size.
  5. Press Create, check the preview and the pixel size, then download the file.

About this tool

3.5 cm × 4.5 cm is the same size as 35 × 45 mm. At 300 DPI it is 413 × 531 pixels, which is what this page produces. The other common settings work out to 207 × 266 px at 150 DPI; 413 × 531 px at 300 DPI; 827 × 1063 px at 600 DPI.

The shape is a tall rectangle with a ratio of about 7:9. A square or landscape photo has to be cropped to fit it, and the crop box here is locked to that shape for exactly that reason: stretching a face to fit is the usual mistake that gets a photo rejected.

A correct size is only one rule of several. Offices and websites also set the background colour, how large the head must be, and sometimes a maximum file size in KB. This page only handles the crop, the pixel size and the KB limit, so check the other rules in the instructions you were given.

Practical uses

  • Cropping a portrait to a commonly used 3.5 × 4.5 cm photo shape.
  • Producing a 413 × 531 px image for a form that asks for that size.
  • Preparing a print file where the photo will be placed at 3.5 × 4.5 cm.

Tips for better results

  • Take the original with the face centred and some space around the head.
  • Add a KB limit only if your form states one, and read the real size in the result.
  • Resizing produces the size you choose. It cannot make an organisation accept the file, because forms and offices also set rules for background, head position, file type and file size.

Frequently asked questions

How many pixels is 3.5 cm x 4.5 cm?

At 300 DPI it is 413 × 531 pixels. At 150 DPI it is 207 × 265 pixels and at 600 DPI it is 827 × 1063 pixels.

Is 3.5 x 4.5 cm the same as 35 x 45 mm?

Yes. 3.5 cm is 35 mm and 4.5 cm is 45 mm, so the two are the same size written in different units.

Will this photo be accepted?

Size is only one requirement. Check the background, head size and file rules from the organisation that asked for it.

Is my image uploaded?

No. The file is read and rewritten in your browser, and it never leaves your device.
