What does Resize Images do?

Resize Images sets exact dimensions or scales by percentage. People search for it as resize image online, photo resizer, picture resizer, image size converter or change dimensions of image. It is the same job each time: make the picture bigger or smaller in pixels.

How to resize an image

1. Open the tool. Go to Resize Images. It works on phone and desktop.
2. Add your picture. Choose your JPG, PNG or other image.
3. Choose the size. Type the exact width and height in pixels, or scale by percentage.
4. Resize and download. Save the new image and check it.

No sign-up is needed, so it is a resize image online free option.

Ways to resize

• Exact dimensions. Use it to resize pixel sizes, change width and height of image or resize image pixels for a specific requirement.
• Percentage. Scale to 50 percent, for example, to reduce image dimensions quickly.
• Smaller or larger. Use it to downsize image files, or to increase image size and enlarge image dimensions.

Making a picture larger stretches the existing pixels, so it will not add detail. Enlarge only as much as you need.

Common reasons to resize

• Social media posts and profile pictures. Check the platform's current recommended dimensions, then enter them.
• YouTube thumbnails and banners. Set the exact size the platform asks for.
• Logos. Create a smaller or larger version of a resize logo job.
• WhatsApp and chat profile pictures, after cropping with Crop Images.
• Online forms and job portals that ask for a specific pixel size.
• Websites and stores where product photos should all match.

Resize and keep quality

To resize an image without losing quality, keep the aspect ratio (the width-to-height proportion) so the picture is not stretched, and avoid enlarging a small image. Reducing a large picture to a smaller one usually looks clean.

Resize to reduce file size

Smaller dimensions mean a smaller file. If you need to reduce image size in KB or resize image in KB, resize first, then run the picture through Compress Images.
