Frequently asked questions

Common questions about social media image resizing.

What is the best image size for Instagram posts?

For Instagram feed posts, use 1080×1080px for square (1:1), 1080×1350px for portrait (4:5), or 1080×566px for landscape (1.91:1). For Stories and Reels, use 1080×1920px (9:16).

Should I use Cover or Contain mode?

Use Cover mode to fill the entire frame by cropping if needed — ideal for maintaining impact. Use Contain mode to fit the entire image with padding — ideal when you cannot crop any part of the image.

What format should I use for social media images?

JPEG is recommended for photos (smaller file size, faster uploads). Use PNG for graphics with text or logos that need transparency. WebP offers better compression but is not supported by all platforms.

Will resizing reduce image quality?

Our tool maintains maximum quality during resizing. When downloading, use 80–90% quality for JPEG to balance file size and quality. PNG is lossless but creates larger files.

Can I resize multiple images at once?

Currently, the tool processes one image at a time to ensure precise control over each resize. For batch processing, you will need to resize each image individually.

Do social media platforms compress images?

Yes, all platforms apply their own compression. To minimise quality loss, upload images at the exact recommended dimensions and keep file size under 1 MB for posts and 5 MB for covers.
