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.
