What is Batch Resize?

Batch Resize lets you resize multiple images simultaneously with a single click. Upload dozens of photos, set your target dimensions or scale percentage, and download all resized images instantly. Perfect for preparing product photos, social media assets, or website images that all need the same dimensions.

How to Batch Resize Images Online

Select or drag multiple images to get started. Choose your resize method: set exact pixel dimensions, scale by percentage (10%-200%), or specify the longest side length. The tool previews new dimensions for each image before processing. Click Download All to save every resized image in your chosen format with optimized quality settings.

Three Resize Modes for Every Need

Dimensions mode sets exact width and height with contain, cover, or stretch options. Percentage mode scales all images proportionally - use 50% to halve file sizes for email attachments or 200% to double resolution. Longest Side mode is ideal for photographers who want consistent maximum dimensions while preserving each image's unique aspect ratio.

When to Use Batch Resize

Use batch resize for e-commerce product listings that require uniform 1000x1000 thumbnails, social media campaigns needing consistent image sizes, website galleries with standardized dimensions, or reducing photo library sizes for cloud storage. Batch processing saves hours compared to resizing images one at a time in desktop software.

Quality Preservation and Format Options

All resizing uses high-quality bicubic interpolation for smooth results. Adjust output quality from 1-100% to balance file size and visual fidelity. Export as JPG for photographs with smallest file sizes, PNG for graphics with transparency, or WebP for modern web optimization with 30-50% smaller files than JPEG at equivalent quality.
