How to use the image resizer

Set the width you need — 1080 for Instagram, 1920 for a slide, 400 for an avatar — and every image you drop is redrawn to that size on your own machine. Aspect ratio is kept unless you say otherwise.

  1. Drop your images

    JPG, PNG, and WebP, up to twenty at a time. Drag them in, browse for them, or paste a screenshot straight from the clipboard.

  2. Choose the target size

    Type a width and the height follows the original proportions. Switch to percentage for “half of whatever this is”, or unlock the ratio to force exact dimensions.

  3. Download

    One file or all of them. Each card shows the old and new dimensions so you can check before saving.

About this tool

Most “resize online” sites upload your photo, resize it on a server, and hand back a link — which means a copy of your passport scan or your child’s school photo sits in someone else’s storage. There is no technical reason for that: browsers have been able to decode, scale, and re-encode images for over a decade.

For social platforms, resize to the platform’s own dimensions before uploading. Their servers will re-encode whatever you send, and starting from a file that is already the right size gives their compressor less reason to be aggressive.

Frequently asked questions

Does resizing lose quality?
Making an image smaller is safe — you are discarding detail you were not going to see. Making it larger only stretches the pixels you already have; it cannot invent detail, so a 400px photo blown up to 2000px looks soft no matter which tool does it.
Can I resize without changing the shape?
That is the default. Link stays on, you type one dimension, and the other is computed. Turn the link off only when a form demands exact pixels and you accept the squash.
How is this different from compressing?
Resizing changes the dimensions; compressing changes the file size at the same dimensions. Doing both is usually the fastest way under an upload limit — resize first, then compress.
Are my photos uploaded?
No. Decoding and redrawing happen through the Canvas API in this tab. Turn off your Wi-Fi after the page loads and the tool still works.
