The Ultimate Free Batch Image Optimizer & Video Converter (No Uploads)

Every web developer and SEO specialist knows the struggle: you have 500 product images to optimize, and every online tool either asks for a credit card, limits you to 20 files, or makes you upload sensitive assets to a random server.

That's exactly why I built the Image Optimiser by Hafiz. It’s a tool born out of frustration and the need for a privacy-first, unlimited bulk solution.

Why "Local" Processing Matters

Most online tools process your files on their servers. This means:

  • Privacy Risk: Your personal photos or client assets are uploaded to a cloud.
  • Slow Speeds: You have to wait for uploads and downloads.
  • Limits: Servers cost money, so they cap your usage.

My tool uses WebAssembly and HTML5 Canvas to process everything inside your browser. It uses your computer's power, meaning it's as fast as your device and has zero limits.

Key Features

  • Batch to WebP: Convert thousands of JPG/PNGs to WebP automatically.
  • Video Compression: Convert heavy MP4 hero sections to lightweight WebM format.
  • Smart Resizing: Bulk resize images to specific dimensions (e.g., 1200px width) while maintaining aspect ratio.
  • Folder Preservation: Maintains your exact folder structure in the output ZIP, so you don't have to reorganize files.

How to Use It for SEO

Google loves WebP. It's often 30-50% smaller than JPEG with the same quality. Here is my workflow:

  1. Drag your entire assets folder into the tool.
  2. Select "WEBP" as the format.
  3. Hit "Process All".
  4. Download the ZIP and upload to your website.
