Resize images to exact pixel dimensions or percentage scale. Includes presets for Instagram, Twitter, Facebook and other platforms. Works in your browser.

Enter custom dimensions or choose from our platform presets including Instagram Square (1080×1080), Instagram Story (1080×1920), Twitter Header (1500×500) and Facebook Cover (820×312). Lock the aspect ratio to prevent distortion.

Choose your output format (JPG, PNG or WEBP) and quality level. The resized image is processed entirely in your browser using the Canvas API — your original image is never uploaded anywhere.

Frequently Asked Questions

Can I resize without distorting the image?

Yes. Enable the Lock Aspect Ratio toggle and adjusting one dimension will automatically update the other to maintain proportions.

What is the maximum resolution I can resize to?

There is no maximum — you can upscale images to any resolution. However, upscaling beyond 2x the original size may result in visible quality loss.

Which preset should I use for Instagram?

Use 1080×1080 for square feed posts, 1080×1350 for portrait posts, and 1080×1920 for Stories and Reels.

Can I resize multiple images at once?

Currently the tool resizes one image at a time. For batch resizing, use our Image Compressor tool which processes multiple files simultaneously.
