Resize an Image in Pixels

Type the pixel width you need and this page redraws your photo at it, working the height out from the shape you already have. Fill in both numbers instead if a site demanded an exact grid. Everything happens on your device.

How to resize an image in pixels

  1. Tap Choose a photo and pick your image.
  2. The width starts at 1080 pixels — change it, or type a height instead.
  3. Tap Resize in pixels and save the result.

One number is usually the right amount of instruction

Sites almost always care about one dimension. A blog wants images no wider than 1200; a marketplace wants the long edge at 1600; a forum caps the width and lets the height fall where it may. Giving one number and leaving the other blank is both the least work and the only version that cannot distort the picture.

Both numbers matter when the target is a fixed frame — a 1080 by 1080 profile square, a 1920 by 1080 slide. Unlock the shape, type both, and accept that a photo whose proportions differ will be stretched to fit rather than cropped to fit.

Common pixel sizes worth knowing

1080 across suits almost every social upload and is small enough to send over a patchy connection. 1920 is the point past which most screens stop showing you any more detail. 640 is comfortable for an email attachment. Government portals that name pixels usually want something between 150 and 350 on the long edge, which is far smaller than anything a phone shoots.

Whatever the number, the tool never enlarges by default — a photo already narrower than your target comes back untouched rather than blown up and soft.

Questions

Which side is width and which is height?
Width is across, height is down, and the tool reads them against the photo the way you see it — including photos your phone stored sideways with a rotation tag.
Can I make an image bigger?
Enlarging is off by default because it invents detail rather than recovering it. The pages that promise an exact physical size turn it on, because there the size is the requirement.
Does resizing lose quality?
Making an image smaller discards detail you can no longer see at that size, which is the point. The tool averages the pixels it removes rather than dropping them, so edges and hair stay smooth instead of stair-stepping.
