Image resizing FAQ
Will the tool crop my image?
No. Presets fit the image within the chosen box. Exact dimensions can stretch if aspect ratio lock is off.
Can I resize for social previews?
Yes. The preset list includes common square, vertical, banner, and share image sizes.
What format is exported?
The tool keeps the original format unless the browser cannot export it safely, then it falls back to PNG.
