Resize image dimensions for a website or social post

Pixel dimensions describe the width and height of the image, while file size describes the space it takes to store. Reducing dimensions often reduces both, which can make a photo easier to upload and faster to display. Start with the display size you actually need instead of sending a full camera-resolution image everywhere.

Keep image proportions when changing the size

Preserving the aspect ratio keeps a face, logo, or product from looking stretched. When a destination requires an exact square, fitting with a background or cropping can be a better choice than changing the width and height independently. Use the Square Image tool for those 1:1 layouts.

Understand what image resizing can and cannot improve

A larger export contains more pixels, but it does not recover detail that the source never captured. For a sharp result, use a clear original and avoid unnecessary enlargement. PNG suits transparent artwork, while JPG or WebP can be practical for photographic images when smaller files matter.

GOOD QUESTIONS

Resize Image online: frequently asked questions

All FAQs

How do I resize a photo to an exact pixel width?

Load the photo and enter the desired width. Keep the aspect-ratio option enabled if you want the height to follow the original proportions.

Can I resize an image to a square without stretching?

Use Square Image and choose Blur, Color, or Crop. Those modes create a square while keeping the source proportions.

Does making an image larger improve its detail?

No. Ordinary resizing creates more pixels but cannot restore detail missing from the source. Start with an image at least as large as the intended output when possible.

Is resizing the same as compressing?

Resizing changes pixel dimensions. Compression changes how the image data is encoded. Both can reduce file size, but they affect the image differently.
