Can I resize without stretching?

Yes. Keep the aspect ratio locked so width and height scale together.

Does upsizing improve quality?

No. Enlarging adds pixels by interpolation and cannot restore detail that was never there.

Is there a size limit?

Limits depend on your browser and device memory. Very large images may be slow or fail on low-memory devices.
