How to Bulk Compress Multiple Images at Once

Why Bulk Compress Images?

Compressing images one by one is tedious. If you have 50 product photos to optimize for your online store, or 100 event photos to resize before uploading, doing them individually would take forever. Bulk compression processes all your images in one batch.

Common use cases:

Optimizing all images on a website before launch

Preparing a full product catalog for an e-commerce store

Reducing a folder of photos before archiving or backup

Compressing images for a newsletter or email campaign

How to Bulk Compress Images with OxFile

Step 1: Open the Bulk Compress tool on OxFile. Step 2: Select all the images you want to compress — click "Select Files" or drag multiple images at once into the tool. Step 3: Choose your compression quality setting (applies to all images in the batch). Step 4: Click "Compress All" and wait while all images are processed. Step 5: Download all compressed images as a ZIP file, or download them individually.

Tips for Bulk Compression

Same settings for consistency: Bulk compression applies the same quality setting to all images, ensuring consistent visual quality across your batch.

Sort and filter first: Remove images you don't need to compress before uploading the batch.

Check a few samples: After downloading the ZIP, spot-check a few images to confirm the quality is acceptable before using them.

Web optimization: For website images, 80% quality with a maximum width of 1200px is a good starting point.

Privacy and Security

All compression runs locally in your browser. Even when processing 50 images at once, none of them are uploaded to any server. Your files stay on your device throughout the entire process.
