About This Tool

Image Compressor

Compress JPEG, PNG, and WebP images in your browser without uploading to any server — reduce file size while keeping great quality.

Why Use This Tool?

  • Compress product images before uploading to your e-commerce store
  • Reduce image sizes for faster website loading and better SEO
  • Compress photos before sending over WhatsApp or email
  • Optimise images to pass Core Web Vitals LCP requirements
  • No image leaves your device — 100% private, browser-based processing

Overview

Images are the largest contributors to webpage weight. According to HTTP Archive data, images account for over 50% of the average webpage's total bytes transferred. Large, unoptimised images slow down page loads, hurt Core Web Vitals scores, cost more in bandwidth, and create a poor user experience on mobile connections. Our Image Compressor lets you reduce image file sizes dramatically — often by 50–80% — while maintaining visually acceptable quality, all without leaving your browser. Choose from JPEG, WebP, or PNG output formats, adjust the compression quality with a slider, and download the optimised result instantly. The tool uses the browser's Canvas API for processing, meaning no image is ever uploaded to any server — your files stay completely private on your device. This is especially important for personal photos, confidential documents, or business images you would not want stored on a third-party server. Use it to optimise product images for your online store, blog images for faster loading, or profile photos for web use.

Frequently Asked Questions

For web images, a quality of 70–80% for JPEG or WebP usually provides an excellent balance of visual quality and file size reduction.
WebP offers the best compression with excellent quality — use it for web. JPEG is universally compatible. PNG is best for images with transparency or sharp graphics like logos.
No. All compression uses the HTML5 Canvas API in your browser. Your images never leave your device — processing is 100% local and private.
No. Compression reduces file size by reducing colour data and removing image metadata. The pixel dimensions remain the same unless you also resize.
The tool handles images up to around 20 MB depending on your device's RAM. Very large RAW or high-resolution images may take a few seconds to process.
