Social Media Dimensions – FAQ

If you upload an image wider than 1080 pixels, Instagram aggressively compresses it with severe loss. Pre-sizing to exactly 1080 px width preserves sharpness.

सरल हिंदी में समझें:यदि आप 1080 पिक्सेल से बड़ी भारी फ़ोटो डालते हैं तो इंस्टाग्राम उसे बेतरतीब कंप्रेस कर देता है। पहले से 1080 px में रिसाइज करके डालने पर फ़ोटो एकदम साफ़ रहती है।
