Professional Image Optimization
High-resolution images are beautiful, but they can slow down your website and consume mobile data. ZapTool's Pro Image Compressor uses advanced browser-based algorithms to strip unnecessary metadata and optimize pixel encoding, giving you the perfect balance between file size and visual clarity.
Smart Compression
Adjust the quality slider to find your sweet spot. We handle the technical heavy lifting.
Local Processing
Your privacy is guaranteed. No data is sent to any server; everything happens in your RAM.
How it works?
When you upload a file, our tool draws it onto an invisible HTML5 canvas. When you move the quality slider, we re-encode that canvas using different compression levels. JPEG and WEBP formats are especially efficient at discarding information that the human eye cannot perceive, allowing for massive size reductions.
Frequently Asked Questions
Will my image look blurry?
Not if you stay above 70% quality. Most images can be reduced by 50% in size without any noticeable difference to the human eye.
Is there a file limit?
We recommend images under 10MB for the smoothest performance in the browser.
