Use a high-res source
Start with an image at least 1080px wide so the result stays sharp.
Keep content in the safe area
Important text and faces should stay within the central region so nothing is cut off on smaller screens.
Export as WebP
WebP at ~90% quality is visually lossless and a fraction of the file size.
Instagram Post — frequently asked questions
What is the correct Instagram Post size?+
The recommended Instagram Post size is 1080 × 1080 pixels (a 1 : 1 aspect ratio).
How do I resize an image to 1080 × 1080?+
Upload your image to BannerCrop AI and choose the Instagram Post preset. Our smart crop centers the subject automatically at the exact 1080 × 1080 size, then you download it — usually in under 15 seconds.
Which file format is best for a Instagram Post?+
WebP gives the best quality-to-size ratio for most banners. Use PNG when you need transparency or crisp text, and JPEG as a universal fallback. BannerCrop AI exports all of these with a live file-size estimate.
Is BannerCrop AI free to use?+
Yes. You can crop and download banners for free, and your images are processed right in your browser — they never leave your device.
