Complete User Guide & Documentation

Getting Started

Welcome to Image Optimizer Pro

Image Optimizer Pro is a powerful, browser-based tool that helps you compress and optimize your images while maintaining quality. All processing happens locally in your browser - no files are uploaded to any server.

Adding Images

Method 1: Drag & Drop

Simply drag image files from your computer and drop them anywhere in the blue drop area. You'll see a visual highlight when files are ready to be dropped.

Method 2: File Selection

Click the "Select Files" button to open your file browser and choose images manually. You can select multiple files at once.

Tip: Supported formats include JPG, PNG, WebP, and GIF. Maximum file size is 25MB.

Compression Settings

Output Format

Choose your preferred output format:

  • JPG: Best for photographs, offers good compression
  • WebP: Modern format with excellent compression
  • PNG: Best for images with transparency

Quality vs Size Threshold

Use the tabs to switch between compression methods:

  • Quality Mode: Set a specific quality percentage (1-100%)
  • Size Threshold: Set a maximum file size target
Pro Tip: Start with 85% quality for a good balance between quality and file size reduction.

File Management

Preview & Organization

After adding files, you can:

  • Drag & Drop: Reorder files by dragging them
  • Select Files: Use checkboxes to select specific files
  • Delete: Remove individual files or selected batches
  • Compare: Click any processed file to see before/after comparison

Batch Operations

Use the action buttons for efficient workflow:

  • Process All Files: Compress all uploaded images
  • Compress Selected: Only process checked files
  • Download All: Download all compressed files
  • Download Selected: Download only checked files

Download Options

Individual vs ZIP Download

Choose how you want to download your optimized images:

  • Individual Files: Each file downloads separately with original names
  • ZIP Archive: All files combined into a single ZIP file (for multiple files)
Note: Files download to your default download folder. No file renaming occurs - original filenames are preserved.
