Instagram is a mobile-first visual platform. If you post an image that does not conform to Instagram's supported aspect ratios, the app will either letterbox it with black bars or crop off important details.
Here is the up-to-date guide on exact image dimensions for every Instagram placement.
1. Instagram Feed Posts
- Portrait (Recommended): 1080 × 1350 pixels (4:5 ratio). This format takes up the maximum vertical screen space as users scroll through their feed, generating higher engagement.
- Square: 1080 × 1080 pixels (1:1 ratio). The classic Instagram format.
- Landscape: 1080 × 566 pixels (1.91:1 ratio). Best for wide scenic photography or cinematic stills.
2. Instagram Stories & Reels
- Resolution: 1080 × 1920 pixels (9:16 aspect ratio).
- Safe Zones: Keep text and stickers at least 250 pixels away from the top and bottom edges so profile avatars, handles, and audio captions do not cover your content.
3. Instagram Profile Picture
- Display Size: 320 × 320 pixels (1:1 circle crop).
- Make sure your logo or face is centered inside the square because Instagram crops it into a circular avatar.

Frequently asked questions
Why does Instagram make my photos look blurry?
If you upload an image wider than 1080px or with a non-standard ratio, Instagram aggressively compresses and crops it. Resizing to exactly 1080px wide before uploading ensures sharp display.
What is the best format for Instagram posts: JPG or PNG?
High-quality JPG is recommended for photos. For illustrations, text posts, or logos, export as PNG to prevent compression artifacts around letters.

Private & Client-Side Image Processing
Your images stay safely in your browser. Here is how our architecture protects you:
Image processing is performed locally in your browser memory for all supported tools, so your selected files never need to be uploaded to an external processing server.
No storage or file harvesting. Because operations occur client-side, we never copy, view, or retain your personal photographs or documents.
Instant speed and zero bandwidth costs. With local Canvas and WebAssembly execution, files are processed at full device speed without cloud upload lag.
