Instagram's exact image dimensions
Instagram crops uploads to specific aspect ratios: 1:1 square posts (1080×1080), 4:5 portrait posts (1080×1350), 9:16 stories and reels (1080×1920), and 1.91:1 link previews (1200×628). Uploading photos that don't match these ratios means Instagram crops them automatically — usually badly.
Resize to the exact size you need
Drop your photos into Converter.Plus's social media resizer, pick the Instagram preset (post, story, or reel), and download the cropped versions. The tool runs on your device — your photos never get uploaded to any third-party server.
Bonus — strip metadata before posting
Every iPhone photo embeds your GPS location. Before posting publicly, run the photos through the EXIF cleaner to strip location, timestamp, and device serial number.
