Resize image

Resize any image by pixels or percentage. Drag to scale, lock the aspect ratio, and watch the new size update live before you download.

This tool lets you resize an image's dimensions and bring its size down in KB. Upload your JPG or PNG, set the width and height, and download a resized image at the KB you need — no signup, no watermark.

Forms and uploads often ask for an exact size — specific pixel dimensions for a passport or profile photo, or a file under a certain number of KB.

How to resize an image's size in KB for free

Resizing an image usually means one of two things: changing its dimensions — the width and height in pixels — or bringing its file size down to a certain number of KB. Often you need both at once, like a passport photo that must be exact pixel dimensions and under a KB limit. This tool handles both: set the size you want and resize the image to fit.

To resize here, upload your JPG or PNG, set the new width and height, and adjust until the file reaches the size in KB you need. Then download the resized image. It's a free way to resize an image's dimensions and size in KB, with no account and no watermark.

Wondering how to resize an image without software? This works right in your browser — no install, no signup, and no need for Paint or an editor on Windows. It's a quick image resizer: set the size, resize, and download. Whether it's a passport photo, a profile picture, or an image for a form, you get exactly the dimensions and KB size you need.

Shrinking an image keeps it sharp, while enlarging a small one can soften it, so resizing down to a requirement works best. Because it runs online, it works the same on Windows, Mac, iPhone and Android, and your files are deleted automatically after processing. A simple way to resize an image's size in KB free online — no account required.
