Yes! Our tool supports batch processing. Simply select multiple files or drag and drop a folder of images to resize them all at once with the same settings.
Aspect ratio is the proportional relationship between width and height. Locking it prevents your image from becoming distorted when resizing. When you change width, height automatically adjusts to maintain proportions.
For web use, 50-75% reduction is often sufficient. For social media, use presets for exact platform requirements. Always check the preview to ensure quality is maintained.
Downscaling (making images smaller) generally maintains good quality. Upscaling (making images larger) can cause quality loss. Use the "Maintain Image Quality" option and keep quality at 85-95% for best results.
Preset sizes are optimized for common use cases: 1080×1080 for Instagram, 1200×630 for Facebook, 1500×500 for Twitter headers, 1920×1080 for HD backgrounds, and more.
