Social media platforms compress every image you upload. This compression is unavoidable, but you can minimize its impact by uploading images in the right format, size, and quality to start with.
Each platform has different compression algorithms and optimal dimensions. Understanding these helps you get the best possible results despite the constraints.
This guide provides platform-specific recommendations for sharing images that look their best on every major social network.

Understanding social media compression
All platforms compress to save bandwidth and storage—you can't prevent this.
However, starting with the right dimensions and quality minimizes degradation.
Over-sized images are downscaled AND compressed—double the damage.
Under-sized images are stretched, making quality issues worse.
Instagram optimization
Feed posts: 1080×1080 (square), 1080×1350 (portrait), or 1080×566 (landscape).
Stories/Reels: 1080×1920 (9:16 ratio).
Upload in high-quality JPEG (92%+) or PNG. Instagram converts to JPEG internally.
Avoid uploading from edited screenshots—use original export from your editing app.
Facebook optimization
Standard posts: 1200×630 works well for most content.
Profile/Cover: Use exact dimensions Facebook specifies (180×180 profile, 820×312 cover).
JPEG works well. PNG may show less compression on graphics with text.
Facebook's quality has improved; reasonable results are achievable.
Twitter/X optimization
In-stream images: 1600×900 (16:9) displays well in timeline.
Square images up to 2048×2048 are supported.
PNG with transparency is preserved (rare among platforms!).
For maximum quality, images under 5MB and 4096×4096 aren't recompressed as aggressively.
LinkedIn optimization
Link preview: 1200×627 for consistent display.
Direct post images: Up to 1080×1080 square or 1920×1080 landscape.
LinkedIn compresses less than some platforms—quality is usually acceptable.
Use JPEG for photos, PNG for graphics with text or logos.
Pinterest optimization
Vertical pins perform best: 1000×1500 (2:3 ratio) is optimal.
Can go up to 1000×2100 for infographic-style pins.
Text overlay should be large and readable at thumbnail size.
Rich, saturated colors stand out in the feed.
