The Ultimate Social Media Image Size Guide (2025)
To resize images for social media without losing quality, use a tool that supports platform-specific aspect ratios (like 1:1 for Instagram or 16:9 for Twitter). Using the correct dimensions ensures your content looks professional and avoids awkward cropping.
Using the correct image dimensions is critical for social media engagement. Platforms like Instagram and LinkedIn frequently update their algorithms and layout specs. If your image is the wrong size, it will be cropped awkwardly or pixelated, making your brand look unprofessional.

Why Image Size Matters for SEO
Large images slow down your website, which hurts your Google rankings. Social media algorithms also penalize content that doesn't fit their native aspect ratios (like posting a horizontal image to TikTok).
Our tool processes images directly in your browser using HTML5 Canvas technology. This means zero data transfer latency and 100% privacy—your photos never leave your device.
