How to use Resize Image Online

Choose an image

Open a JPG, PNG or WebP image from your device.

Reduce the scale

Move the Resize slider from 100% toward 10%. Check the pixel dimensions beneath the preview.

Choose format and save

Review quality, transparency and output size, then download your resized copy.

Example

A 2400 × 1600 pixel photo at 50% scale becomes 1200 × 800 pixels before any rotation. Its pixel count becomes one quarter of the original; its file size will depend on format and quality.

Resize dimensions or reduce KB?

Pixel dimensions describe an image’s width and height. File size in KB or MB describes how much data the saved image uses. Reducing dimensions often reduces file size, but the two are not interchangeable.

This tool uses a 10–100% scale slider and keeps the original proportions. It does not provide separate width and height boxes or a crop-to-fit option. When a form specifies a strict size in KB, use Image Size Reducer and check its minimum pixel dimensions too.

Choose the right output format

Use PNG when you need transparency or sharp line art. JPEG is commonly useful for photographs but does not retain transparency. WebP can be useful where the receiving website or application accepts it. Keep the original and inspect small text after resizing.

What to check

Upscaling increases pixel dimensions but cannot recreate detail absent from the original. This tool’s controls resize by percentage; it is not an AI upscaler.

Common questions

Can I resize an image without uploading it?

Yes. Your selected image is processed in the browser on your device. Loading the site still makes ordinary requests for pages and code.

Will the image keep its proportions?

The percentage slider scales both dimensions together. Rotation can swap the displayed width and height.

Can I enter an exact width and height?

This version uses percentage scaling rather than exact width and height fields. Check the displayed output dimensions before saving.

Does making an image smaller guarantee a particular file size?

No. Output format, quality and image content affect the saved byte size. Use Image Size Reducer for a target-size workflow and inspect the actual result.
