Can I resize an image without losing quality?

Resizing up (upscaling) always reduces sharpness. Resizing down (downscaling) keeps quality. For AI-powered upscaling, use our Upscale Image tool.

Can I keep the aspect ratio?

Yes. Enable the "Keep aspect ratio" option and entering one dimension will auto-calculate the other.

You can resize up to 10,000 × 10,000 pixels on the free tool.

Yes. Common presets include 1200×630 (Open Graph), 1080×1080 (Instagram), 1500×500 (Twitter header).

No. The output keeps the same format as the input. Use our Convert Image tool to change format.

Change the dimensions of your images. Proportions are automatically preserved.
