About This Tool

Cut an image's file size down without a visible drop in quality, which speeds up page loads and gets you under upload limits. Everything runs through the browser's own image processing, so nothing is uploaded just to compress it.

Frequently Asked Questions

Are my images uploaded to any server?+
No. The entire compression process runs locally in your browser using the HTML5 Canvas API. Your files never leave your computer, ensuring complete privacy.
Does compressing an image reduce its quality?+
Yes, but you can control the quality slider. We use smart compression to keep the visual difference imperceptible while drastically reducing the file size.
What file formats are supported?+
We support standard web image formats: PNG, JPG/JPEG, and WebP format images.
