YAIRIX - Photo Optimizer

A free Chrome extension to compress JPG and PNG images in your browser — batch image compression with adjustable quality, 100% offline and private.

YAIRIX - Photo Optimizer is a lightweight image compressor that reduces photo file size without visibly losing quality. Drag and drop up to 100 images, pick a compression level, and download optimized photos individually or as a single ZIP. No uploads, no servers, no sign-up — every byte stays on your device.

Features

• Compress JPG, JPEG, and PNG images directly in Chrome
• Adjustable compression level (1 = light, 10 = super) with a simple slider
• Batch image compression — optimize up to 100 photos at once
• Drag & drop or click to browse for a fast workflow
• Before/after file sizes with savings percentage for every image
• Download individually or as a ZIP (powered by JSZip)
• Custom filename suffix (e.g. photo.png → photo-opt.png)
• Never inflates files — if re-encoding would make an image larger, the original is kept
• 100% offline — zero network requests, zero permissions
• Clean, modern, dark-themed UI
