Frequently Asked Questions

How do I resize an image without distorting it?+

Enable 'Lock aspect ratio' before entering your dimensions. The tool calculates the other dimension automatically to maintain the original proportions.

What image dimensions does Instagram require?+

Square posts: 1080×1080px. Portrait: 1080×1350px. Landscape: 1080×608px. Stories and Reels: 1080×1920px.

Will resizing reduce image quality?+

Enlarging beyond the original resolution always reduces sharpness. Reducing size preserves visible quality while lowering file size. For best upscale results, use the Image Upscaler tool.

Is there a maximum resolution I can resize to?+

No enforced limit, but dimensions over 10,000×10,000px may be slow to process in the browser. For very large output, a desktop tool is recommended.
