Batch Image Processing: Convert, Resize, and Compress in Bulk

Save hours by processing multiple images at once. Learn batch conversion, resizing, and compression techniques — all in your browser.

Processing images one by one is time-consuming when you have dozens or hundreds of files. E-commerce stores, blogs, social media managers, and photographers regularly need to convert, resize, or compress batches of images.

ConvertCraft's image tools support batch operations natively. Drop multiple files at once, apply your settings, and download all results as individual files or a single ZIP archive.

Batch conversion is the most common operation: converting a folder of HEIC photos to JPG, WebP images to PNG, or RAW files to a web-friendly format. The Image Converter handles up to 50 files per batch across 20+ format combinations.

Batch resizing is essential for web optimization. Set a maximum width (e.g., 1200px for blog images, 800px for thumbnails) and the tool resizes every image while maintaining aspect ratios. Output is consistent and ready for upload.

Batch compression reduces file sizes for faster page loads. The Image Compressor analyzes each image individually and applies optimal compression — photos get lossy compression while graphics with text get PNG optimization. All processing happens locally in your browser.
