Overview

Batch Image Compress allows you to quickly reduce the file size of up to 100 images simultaneously while maintaining control over quality, output formats, and metadata settings.

When to Use

  • •Preparing large batches of images for faster website loading speeds.
  • •Reducing file sizes to meet email attachment or upload limit requirements.
  • •Standardizing image formats and quality across a large collection of assets.

How It Works

  • •Upload up to 100 image files in supported formats like JPEG, PNG, WebP, or AVIF.
  • •Adjust your preferred compression settings, including target quality, output format, and resizing options.
  • •Process the files in bulk and download the optimized images directly to your device.

Use Cases

Optimizing high-resolution photography for web galleries to improve page performance.
Batch converting a folder of PNGs to WebP format for modern browser compatibility.
Shrinking large image files to fit within specific storage or email size constraints.

Examples

1. Optimizing Website Assets

Web Developer
Background
A developer needs to upload 50 product images to a website, but the raw files are too large and will slow down page load times.
Problem
Reduce file sizes significantly without noticeable loss in visual quality.
How to Use
Upload the 50 images, set the output format to WebP, and select the 'Balanced' compression method.
Example Config
outputFormat: webp, compressionMethod: balanced, progressive: true
Outcome
The images are converted to WebP and compressed, resulting in a much smaller total site footprint while maintaining high visual fidelity.

2. Preparing Email Attachments

Office Administrator
Background
An administrator needs to send a report containing 20 high-resolution photos, but the total size exceeds the email provider's 25MB limit.
Problem
Compress images to fit within the email attachment limit.
How to Use
Upload the 20 photos and set a 'Target Size per File' to ensure the total batch size is well under the limit.
Example Config
targetSize: 1, targetQuality: 60, keepOriginalNames: true
Outcome
All 20 images are compressed to approximately 1MB each, allowing the entire set to be sent in a single email.
