Change an image's size in pixels or by percentage, with an aspect-ratio lock so nothing gets distorted, and download it in the format you want. All in your browser, without uploading the file.
Resize an image →An image's weight depends mostly on how many pixels it has. Halving both width and height leaves a quarter of the pixels — a huge saving, and if the image will be displayed at that size anyway, you lose nothing useful. If a photo is too heavy, start here before forcing compression.
Worth saying plainly: enlarging adds no detail. Interpolation stretches the pixels that already exist; it cannot invent the ones the photo never captured. The result looks softer or blocky. No resizing tool does magic here, so when you set a size above the original we'll tell you rather than let you believe otherwise.
It keeps width and height in proportion so the image isn't distorted, and it's on by default because that's what you want almost always. Unlock it to set both sides freely — useful when you need an exact measurement and don't mind stretching.
No. Enlarging stretches existing pixels; it can't add detail the file doesn't have.
It keeps width/height in proportion: change one side and the other follows, so nothing distorts.
Yes, usually the most effective way: half the width and height leaves a quarter of the pixels.
No: it runs in your browser and the image never leaves your machine.
