How to Resize an Image for Instagram?
Instagram requires specific aspect ratios to ensure your photos aren't cut off. Use our "Crop" feature to select the "4:5" preset for portraits or "1:1" for square posts. Then, use the resize tab to set the width to 1080 pixels for the best quality.
How to Compress Images for Websites?
Large images slow down websites, hurting your SEO rankings. Use our tool to compress images. Simply upload your high-res photo, select the "WebP" format, and lower the quality slider to around 80%. This can reduce file size by up to 90% with barely visible quality loss.
