Resize Images Online

Resizing an image here is a four-step loop: drop the file, pick a mode, set the target size, and download. The tool accepts JPG, PNG, and WebP files up to 50 MB and redraws the image at the new dimensions inside your browser with the Canvas API, so nothing uploads and the result is ready the moment you click Resize. Shrinking removes pixels and keeps the visible detail, which is why it also cuts file size: a 4000x3000 phone photo dropped to 1600px wide typically falls from around 4 MB to under 700 KB with no visible change at normal screen sizes. Enlarging past the original is the opposite trade, because the browser has to invent pixels that were never captured and the result turns soft.

1. 1Drop or select an image. JPG, PNG, and WebP files up to 50 MB are accepted.
2. 2Choose a mode: Pixels for an exact width and height, Percent to scale by a percentage, or Max dimension for a longest-edge limit.
3. 3Enter the target size. With the aspect ratio lock on, editing one side updates the other automatically.
4. 4Click Resize and download. Your original file is never modified.

• Pixels sets an exact width and height. Use it when a slot has fixed dimensions, such as a 1080x1080 profile picture or a 1200x628 share image.
• Percent scales by a percentage of the original. Entering 50 halves the image and entering 200 doubles it, so it is the fastest way to apply a predictable change.
• Max dimension sets a longest-edge limit such as 1920px and lets the shorter side follow automatically. It is the easiest way to cap every image to a single size.

The aspect ratio lock is on by default, so changing the width updates the height to match and the other way around. That keeps proportions intact and avoids the squashed or stretched look you get when the two sides are typed independently. Turn the lock off only when you deliberately need a distorted result, such as fitting a banner slot with unusual proportions.

The answer depends on the direction. Shrinking removes pixels but preserves visible detail, so a photo resized down looks just as sharp as the original at the same display size. Enlarging past the original is different: the browser interpolates new pixels that were never in the file, so an 800px image stretched to 2400px looks visibly soft. For JPG and WebP output a quality slider controls re-encoding; it is hidden for PNG, where re-encoding is lossless and changes nothing.

Resizing removes pixels and compression discards detail, and they solve different problems. For a large camera photo the order matters: a 4000x3000 image resized to 1600px wide already loses 70-80% of its file size before any quality is lowered, simply because far fewer pixels remain to encode. The rule is to resize to the dimensions you actually need first, then compress the result. This page covers the resize half; the compressor and the fixed-size tools handle the rest.

Every image is processed locally with the Canvas API inside your browser. Nothing uploads, no account is required, and there is no queue to wait in. That makes the tool a sensible choice for sensitive material such as screenshots of internal systems, client assets, or personal photos that you would rather not send to a third-party server. Processing starts the moment you click Resize and a result is usually ready in under a second.
