How to use the Image Resizer
Drop your images, then type a new width or height, or a percentage. With "Keep aspect ratio" on, the other side follows so the picture is not stretched.
Choose the output format and download each image, or all of them together.
Frequently asked questions
What size is a passport photo in pixels?
Rules differ by form. Many Indian online forms ask for about 200 × 230 pixels or 3.5 × 4.5 cm; check the size your form asks for and type it in.
Does resizing reduce quality?
Making an image smaller keeps it sharp. Making it larger than the original cannot add detail, so it looks softer.
