What is Image Compression?

Image compression reduces file size by removing perceptually redundant data while preserving visual quality. Smaller images load faster, save bandwidth, and improve Core Web Vitals scores — particularly Largest Contentful Paint (LCP). This tool uses your browser's native canvas API to recompress images at the quality level you choose, with zero server uploads.

Common use cases

  • Reduce hero images to improve LCP and Core Web Vitals.

  • Compress photos before email attachments.

  • Optimize product images for ecommerce stores.

  • Shrink blog post images for faster page loads.

Frequently asked questions

Is my image uploaded anywhere?
No. All compression happens in your browser using the canvas API. Your image never leaves your device.
What's the best quality setting?
For web use, 70–80% quality is usually indistinguishable from the original at much smaller file sizes.
Does this work for PNG?
Yes — PNGs are re-encoded as JPEG when you compress. For lossless PNG optimization, use a dedicated PNG optimizer.
