When you have dozens or hundreds of images to compress — for a website, e-commerce store, or photo gallery — compressing them one by one wastes hours. Batch compression lets you process all images simultaneously with the same settings in minutes.
When You Need Batch Compression
- Uploading a large product catalogue to an e-commerce store
- Optimising all images on an existing website
- Preparing a photo album for a gallery or portfolio
- Compressing photos for a blog with many images
- Sending a large collection of photos via email or file sharing

Visit imgresizr.com and upload multiple images at once — drag and drop all files into the compress tool. Set your quality target (85% for web photos is a good starting point). Apply the compression and download all files in a single ZIP archive. Every image is compressed with the same settings simultaneously, saving hours of manual work.
Batch Compression Settings Guide
| Use Case | Quality | Format |
|---|---|---|
| E-commerce product photos | 85% | JPG |
| Blog inline images | 80% | JPG |
| Screenshot collections | Lossless | PNG |
| Social media assets | 85% | JPG |
Tips for Effective Batch Compression
- Sort images by type before batching — photos and screenshots need different settings
- Set a consistent output size for galleries — same dimensions create a professional, uniform look
- Name files logically before compressing — batch tools often preserve file names
- Always keep original full-resolution copies before batch compressing
- Test one image first to verify the quality setting is right before running the full batch
