How to resize an image

1 Add an image; its current dimensions fill the width and height fields.
2 Type the target width or height; with the aspect ratio locked, the other value follows automatically so nothing gets distorted.
3 Untick the lock only when you deliberately want to stretch or squeeze the image.
4 Press Resize, check the preview, and download as JPG, PNG or WebP.

Does enlarging an image improve its quality?: No. Upscaling spreads the existing pixels over a larger area, which looks soft. Shrinking is safe; meaningful enlargement needs an AI upscaler.
What sizes are typical for the web?: Full-width hero images around 1600-2000 px wide, content images 800-1200 px, thumbnails 300-400 px. Larger than the displayed size only wastes bandwidth.
Which output format should I pick?: JPG for photos, PNG when transparency or crisp graphics matter, WebP for the smallest files on the web.
Is my image uploaded anywhere?: No. Resizing runs entirely in your browser; the image never leaves your device.

Smaller files, quality you control, results you see instantly.

The exact pixels every platform wants, in one click.
