Forms often ask for a photo of a specific size, such as 200 × 230 pixels or 3.5 × 4.5 cm. Type the dimensions, choose whether to crop to fit or add a white border, set a KB range if needed, and download a ready-to-upload JPG.
Tips for the best result
- Crop to fit fills the whole frame (best for face photos). Add white border keeps the whole picture visible (best for signatures and documents).
- For centimetre sizes, keep the default 200 DPI unless your form names a different resolution.
- Leave one of width or height empty to keep the original proportions.

Frequently asked questions
How do I resize a photo to 200 × 230 pixels?
Choose Pixels, type 200 for width and 230 for height, pick Crop to fit, then click Resize image.
How do I resize an image in cm?
Choose cm, type the width and height (for example 3.5 and 4.5) and keep 200 DPI unless your form specifies another resolution. The DPI is saved in the JPG.
Will my photo be stretched?
No. Crop to fit trims the edges evenly, and Add white border fits the photo inside the frame. The picture is never distorted.
