Convert PNG Images to JPG for Social Media
Overview
Facebook, LinkedIn, and Twitter all convert PNG uploads to JPG internally before displaying them, applying their own compression. Feeding a pre-compressed JPG to these platforms reduces double-compression artifacts. Convert to JPG at 85% quality and set the width to 1200px before uploading.
How to Use This Tool
Upload your PNG. Set quality to 85% and width to 1200px. Click Convert to JPG. Upload the resulting JPG to your social platform. The image will look sharper than if you let the platform convert it from PNG.

Does Facebook compress PNG images?
Yes. Facebook converts all images to JPG internally. A PNG uploaded to Facebook is re-encoded to JPG at roughly 85% quality. Uploading a pre-optimized JPG gives you control over the first compression pass.
What is the best image size for Facebook posts?
Facebook recommends 1200x630px for shared links and 1080x1080px for square posts. Images over 100KB are re-compressed. Target under 100KB at 1200px wide for minimum Facebook recompression.
Should I use PNG or JPG for LinkedIn posts?
JPG for photographs. PNG for infographics with text or sharp graphics. LinkedIn applies JPG compression to all uploads, so pre-compressing as JPG at 85% quality gives you better control.
