Frequently Asked Questions
What are the best image sizes for social media in 2026?▼
For Instagram: 1080×1080 (Square) or 1080×1350 (Portrait). Facebook: 1200×630 (Link) or 1080×1080. Twitter: 1200×675. LinkedIn: 1200×627. Pinterest: 1000×1500 (2:3). TikTok: 1080×1920.
How do I optimize images for Instagram quality?▼
Instagram compresses aggressively. Resize your image to exactly 1080px wide before uploading. Use Quality 80-90 JPGs. Avoid uploading 4K images as Instagram's compression algorithm often makes them blurry.
What aspect ratio is best for mobile feeds?▼
Vertical 4:5 (1080×1350px) is king. It takes up the most screen real estate on mobile devices (Instagram/Facebook), grabbing more attention than square or landscape images.
Does PNG or JPG look better on Facebook?▼
JPG is generally better for photos. Facebook converts most PNGs to JPGs anyway, often introducing artifacts. Use PNG only for logos or graphics with few colors, and keep the file size small (<1MB).
What is the perfect YouTube thumbnail size?▼
1280×720 pixels (16:9 ratio). Keep the file size under 2MB. Use high-contrast text and bright colors to stand out.
