Private File Reducer helps merchants reduce the size of product images directly in their browser. Images are compressed locally and uploaded back to Shopify only when the optimized version is smaller. The app preserves image dimensions and format, supports bulk optimization, and never sends images to external servers for processing, giving merchants a simple way to improve store performance while keeping full control of their files.

• Compress multiple product images in a single operation.
• Process images locally in the browser without sending them to external servers.
• Replace product images only when a smaller optimized version is produced.
• Preserve image dimensions and format during optimization.
• Preview the space saved for each optimized image.
