Does resizing reduce image quality?
+
Downscaling rarely causes visible quality loss. Up-scaling beyond 200 % can introduce softness — for best results, pair the resizer with our AI Enhance tool to sharpen enlarged images.
Is my image uploaded to a server?
+
No. All processing happens inside your browser using the Canvas API. Your file never leaves your device.
What dimensions should I use for an Instagram post?
+
Instagram recommends 1080 x 1080 px for square posts, 1080 x 1350 px for portrait, and 1080 x 566 px for landscape. Our preset menu includes all three options.
