Frequently asked questions

Does resizing reduce image quality?

Downsizing (making smaller) has no visible quality loss. Upsizing (making larger) can introduce softness since pixels are interpolated. For best results when upsizing, use PNG output and keep the scale under 200%.

Are my images uploaded anywhere?

No. All resizing happens in your browser using the HTML5 Canvas API. Your images are never sent to any server.

What is the OG Image preset?

OG Image (1200×630px) is the recommended size for Open Graph images — used when your page is shared on Facebook, LinkedIn, Twitter and WhatsApp. Using the correct size ensures your image displays without cropping.
