Can I resize without distortion?

Yes — use the aspect ratio lock to maintain proportions, or Cover mode to fill a frame by cropping.

Does resizing reduce image quality?

Downscaling reduces file size with minimal quality impact. Upscaling beyond the original dimensions can cause blurriness — use the AI Upscaler for enlarging images with best results.

What is the maximum output resolution?

Up to 8000×8000 pixels. Output is limited by your browser memory for very large images.

Can I resize multiple images at once?

Yes — use the Bulk Resize tool to resize up to 100 images to the same dimensions, downloading results as a ZIP.
