How to resize an image
- Add your images. Pick one or many photos.
- Enter the new size. Choose a unit and type the width or height. Use a quick size for common forms.
- Resize and download. Save each image or all of them as a ZIP.
Resizing in cm or inches
Forms often give photo sizes in centimetres, like 3.5 × 4.5 cm. The pixel size depends on the DPI (dots per inch): at 200 DPI, 3.5 × 4.5 cm is 276 × 354 pixels. Choose the unit and DPI the form asks for and the tool does the maths.
Keep proportions changes the height automatically when you change the width. Untick it to set both, and the tool crops from the centre so your photo is never stretched.

Frequently asked questions
How do I resize a photo to 3.5 × 4.5 cm?
Tap 'Passport 3.5×4.5 cm' under Quick sizes, add your photo, and press Resize. The tool uses 200 DPI, which gives 276 × 354 pixels. Change the DPI if your form needs a different value.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Making it much larger than the original can look blurry, because no new detail is added.
How do I resize and also reduce the file size in KB?
Resize here first, then use the JPEG compressor on the home page to bring it under the KB limit.
