ABOUT THIS TOOL

About the Image Resizer

The HandyTools Image Resizer changes the width and height of a picture. Type the dimensions you need or pick a preset such as Instagram square (1080 × 1080), Instagram portrait (1080 × 1350), a link preview (1200 × 630), a YouTube thumbnail (1280 × 720) or Full HD (1920 × 1080).

Keep the aspect ratio option stops the picture from stretching, and an optional sharpen step can help when you shrink a large image. The work is done in your browser and the result downloads as a PNG.

Tips for best results

Leave Keep aspect ratio on unless you really want to change the shape of the image.
Making an image much larger than the original cannot add detail, so it may look soft.
Sizes up to 12,000 pixels on each side are supported.

Frequently asked questions

How do I resize an image without stretching it?

Keep the aspect ratio option adjusts one dimension automatically so the picture keeps its proportions.

What sizes should I use for social media?

Use the built-in presets: for example 1080 × 1080 for a square post and 1080 × 1920 for a story, reel or TikTok.

Does resizing upload my image?

No. Resizing is processed in your browser.
