Frequently Asked Questions
Why is 4:5 the best aspect ratio for Instagram posts?
The 4:5 portrait ratio (1080×1350 px) occupies the maximum vertical space allowed by Instagram in the feed — 20% more screen real estate than a square post. More screen area means more visual impact, higher scroll-stop rate, and typically a better engagement rate compared to 1:1 or 1.91:1 landscape formats.
Can I use this to prepare a multi-image Instagram carousel?
Yes. Upload up to 10 images, apply the same 4:5 crop to all via "Apply to all", then download the batch as a ZIP. All slides will be uniform in ratio and quality, ready to upload directly as an Instagram carousel with consistent visual alignment across every panel.
Should I export Instagram photos as JPEG or WebP?
Instagram re-encodes all uploads to JPEG internally, so exporting as JPEG at quality 85–90% gives the most predictable output. WebP is useful for keeping a smaller master archive before uploading. Both formats are available directly from the interface.
