Built different from the ground up. No server-side tricks — just raw browser power. Your files never leave your device. GDPR & CCPA compliant.
Your images are processed entirely in your browser using advanced Web Workers. Files never leave your device — no server uploads, no cloud storage, no third-party access. Period.
No upload wait times. No download delays. Compression starts the instant you drop your files. Works offline once loaded — even on airplane mode.
Convert between JPG, PNG, WebP, and AVIF. Use next-gen formats to save up to 50% more space compared to traditional JPEGs — all while maintaining visual quality.
Process dozens of images at once. No per-image limits, no daily caps, no "upgrade to Pro" gates. Compress as many images as you need, whenever you need.
Resize images during compression with preset breakpoints (1024px, 800px, 640px) or custom dimensions. Perfect for optimizing images for specific platforms.
Automatically cleans and optimizes filenames for search engines. Removes special characters, normalizes spacing, and produces clean, URL-friendly names.

Yes — 100% free with no limits. No hidden fees, no premium tiers, no watermarks. We monetize through non-intrusive ads, not your data.
Never. This is our core differentiator. Unlike TinyPNG or Compressor.io, your images are processed entirely in your browser using JavaScript Web Workers. Your files never leave your device. This makes us inherently GDPR/CCPA compliant — there's simply no data to protect because we never have it.
We support JPG/JPEG, PNG, WebP, and AVIF. You can also convert between formats during compression — for example, convert a JPG to WebP for up to 30% smaller file sizes with the same visual quality.
TinyPNG uploads your images to their servers and limits free users to 20 images per upload (5 MB max each). Squoosh is client-side but its web app only processes one image at a time. Image Compress gives you the best of both worlds: client-side privacy + unlimited bulk compression + format conversion + free resize — all in a single tool.
You're in full control. The quality slider lets you find the sweet spot between file size and visual quality. At 80% quality, most images see a 60-80% size reduction with virtually no visible difference.
Absolutely. There are no restrictions on usage. Use Image Compress for personal projects, client work, e-commerce, social media, blogs — anything you need.
