About Bulk Image Compressor

Useful details for choosing formats, browser settings, and privacy-safe local processing.

What Bulk Image Compressor does

Bulk Image Compressor is built for reducing image file size before an upload, email, form submission, or website publish.

The page keeps the workflow simple: add images, choose a target or quality level, process locally, and download the smaller files.

  • Best for: E-commerce uploads, Blog media libraries, Client photo batches, Email bundles
  • Input: JPG, PNG, WebP, and browser-supported images
  • Output: compressed image

Settings and output control

The metadata option focuses on camera, device, time, and location data that can be embedded inside common photo files.

A clean copy is safer for public uploads because it removes typical hidden metadata while keeping the visible image content.

  • Files stay on this device by default
  • Batch export is available after processing
  • Metadata cleanup is available when privacy matters

Browser support and practical limits

The browser-safe limits are designed for reliability: up to 50 desktop images, a 32 MB file-size guard, and an 8192 x 4096 px image-size guard.

Mobile browsers often have less memory available, so smaller batches are recommended on phones and tablets.

  • Desktop batch: up to 50 images
  • Max image size: 8192 x 4096 px each
  • Mobile: smaller batches recommended
