Frequently Asked Questions

Will resizing reduce image quality?
Downscaling generally preserves sharpness. Upscaling beyond the original size may look soft because new pixels are interpolated — use modest target dimensions for best results.
Can I keep the aspect ratio locked?
Yes — enable maintain aspect ratio so changing width automatically adjusts height (or vice versa) without stretching the image.
Are my photos uploaded to a server?
SeerKits resizes images locally in supported browsers. Your files stay on your device with no signup required.
