Why Social Media Destroys Image Quality
Every major social media platform — Instagram, WhatsApp, Facebook, Twitter/X — automatically recompresses images you upload. If your image is too large, their algorithms apply aggressive compression that can introduce visible artifacts, especially in dark areas and gradients. Pre-compressing at the right quality and dimensions prevents this.
Optimal Image Settings by Platform

- Instagram recompresses if file is over ~1MB — aim for 800KB–1MB

- WhatsApp applies heavy compression to large files, often introducing banding

For profile pictures and images with text, use PNG format. Most platforms handle PNG losslessly or with less aggressive compression, resulting in sharper, cleaner results — especially for logos and text-heavy graphics.
