What this tool does

Batch Image Compressor applies a single quality and optional scale preset to every image in your queue—ideal when a photoshoot export or CMS migration leaves hundreds of oversized files.

Unlike one-at-a-time cloud tools, the whole folder processes locally and downloads as individual files or one ZIP archive without uploading your catalog to a third party.

Why you might need it

Website migrations and marketplace bulk uploads punish teams who compress images one by one. One session can cut a 400 MB export to a deployable size.

Agencies delivering client galleries need predictable compression across SKUs so no single hero image blows the LCP budget on a category page.

Common use cases

  • Compress an entire WordPress media export before CDN upload
  • Shrink event photography folders for client download links
  • Prepare hundreds of Etsy listing photos under platform limits
  • Normalize quality across mixed JPG and PNG supplier assets
  • Reduce repo size of static site image folders in Git

Step-by-step guide

  1. 1Drag a folder or multi-select all images into the batch queue.
  2. 2Set the quality slider—start around 80 for photos, higher for product shots with fine text.
  3. 3Optional: enable metadata stripping and slight scale-down for aggressive size wins.
  4. 4Click Compress All and wait for the in-browser progress bar to finish.
  5. 5Download ZIP or individual files and spot-check three random outputs before bulk replace.

Tips & best practices

  • Sort by file size in your OS first—compress the largest 20% manually if the tab feels slow on low RAM.
  • Use JPEG Compressor or PNG Compressor when one format needs different quality than another; batch mode shares one setting.
  • Resize Image before batch compress when pixel dimensions—not just encoding—cause bloat.
  • Keep lossless masters archived; batch outputs are delivery copies, not editing sources.

Limitations

  • One quality preset for all formats in queue—mixed PNG icons and JPG photos may need separate passes.
  • Very large batches on 8 GB RAM laptops may need splitting into chunks of 50–100 files.
  • Common mistake — compressing already-compressed social downloads twice: start from highest-quality sources.
