How to use it
- Tap “Select Image” and choose your photo.
- Pick a quick size (like 200 × 230 px or 3.5 × 4.5 cm) or type your own width and height in px, cm, mm, inch or %.
- If the shape changes, choose Crop (drag to position), Fit (white border) or Stretch.
- Choose JPG, PNG or WebP and an optional max file size, then tap Download.
Pixels, centimetres and DPI — what's the difference?
A digital photo is measured in pixels. Centimetres, millimetres and inches only matter when it is printed, and the link between the two is the DPI (dots per inch). At 300 DPI — normal photo-print quality — 1 inch is 300 pixels and 1 cm is about 118 pixels. So a 3.5 × 4.5 cm passport photo is 413 × 531 pixels.
| Size | At 300 DPI | At 200 DPI |
|---|---|---|
| 3.5 × 4.5 cm | 413 × 531 px | 276 × 354 px |
| 2 × 2 inch | 600 × 600 px | 400 × 400 px |
| A4 (21 × 29.7 cm) | 2480 × 3508 px | 1654 × 2339 px |
When you resize in cm, mm or inches, the DPI is also written into the JPG, so Word, printers and photo shops print it at the right physical size.
Crop, Fit or Stretch?
- Crop fills the new shape completely and trims the edges — drag the photo to choose what stays. Best for portrait photos for forms.
- Fit keeps the whole photo and adds a white border where needed. Best for documents and logos.
- Stretch forces the exact size and can distort faces — use it only when shape doesn't matter.
Resizing for online forms
Many forms fix both the pixel size and the file size, such as 200 × 230 px and 20–50 KB for bank exam photos. Pick the size here and set a max file size, or use the dedicated Compress to 50 KB, Signature Resize and Passport Photo tools. Always confirm the requirement in your official notification.
