Image Resizer FAQs

How do I resize an image?

Upload it, enter the width and height you want, choose a format and click Resize Image Now. Then download the resized file. It works in any browser.

How do I resize an image without stretching it?

Scale width and height by the same amount. Halve both for half size, or use the Image Aspect Ratio Calculator to find the matching height for a new width.

How do I resize a photo on Windows?

Open it in Paint, click Resize or press Ctrl + W, choose Pixels, keep Maintain aspect ratio ticked and enter a new width. Then save the file.

How do I resize an image on a Mac?

Open it in Preview, go to Tools > Adjust Size, enter the new width or height and click OK. Keep Scale proportionally ticked to avoid stretching.

What size should images be for a website?

Full-width images usually work at 1200 to 2000 pixels wide, and blog images or thumbnails at 600 to 1200. Smaller files load faster and help Core Web Vitals.

Does resizing reduce image quality?

Making an image smaller keeps it sharp. Making it much bigger can look soft, because new pixels are filled in. For big increases, use the Image Enlarger.

How do I make an image smaller in KB?

Lower the width and height first, since that cuts file size fastest. For photos, saving as JPG or WebP shrinks it further than PNG.

Is the image resizer free?

Yes. It's free with no signup and no watermark, for files up to 5 MB.

Resized? Polish it.

Trim the edges with the Image Cropper or check print sharpness with the Image DPI Checker.
