About the Resize Image

Most platforms enforce specific image dimensions — a marketplace listing, a social media banner, an email signature logo — and uploading an image at the wrong resolution usually gets it auto-cropped or stretched by the receiving platform in ways you don't control. Resizing beforehand, with the aspect ratio you actually intend, avoids that.

This tool resizes by exact pixel dimensions or by percentage scale, with an option to lock the aspect ratio so a width change doesn't distort the image vertically. It handles a batch of up to 20 images at once, which matters when you're preparing a whole product photo set or a batch of thumbnails to the same target size rather than resizing one image at a time.

Frequently Asked Questions

How can I resize images while preserving the aspect ratio?

Choose 'Resize by Dimensions' and leave 'Maintain Aspect Ratio' checked. You can input only the target width or height, and the other dimension will scale automatically.

What does 'Resize by Percentage' do?

It scales down the width and height of the image by a fixed percentage (e.g. 50% reduces both height and width to half). This is a fast way to compress or shrink multiple photos.

Is batch resizing supported?

Yes, you can upload up to 20 images. The selected resizing parameters will be applied to all of them, and you can download the output files in a ZIP archive.
