Local processing Image tools

Resize images

Scale images by width, height or percentage in your browser.

How to use this tool

Add images, set a width, height or percentage, process the batch, then inspect and download the resized files.

Private processing

Your input is processed in this browser tab. PixelKit does not upload it to a file-processing server; leaving the page clears the current work.

Formats and limits

The aspect ratio is always preserved; independent width-and-height stretching is not supported. Dimensions must be 1–12,000 pixels, with a 40-megapixel source limit.

Frequently asked questions

Will resizing stretch my image?

No. You set one side or a percentage and the other side is calculated from the original ratio, so the picture is never distorted.

Does enlarging an image make it sharper?

No. Enlarging adds pixels without adding detail: the file gets heavier while the picture stays as sharp as the source was. Enlarge only when a platform demands a minimum size.

How do I get under a platform size limit?

Resize to the size that will actually be displayed, then compress the result towards the limit rather than compressing the full-size image.
