Optimize your images for the web without sacrificing visual quality. Our tool helps you balance file size and image clarity, ensuring your website loads faster while maintaining a professional look.
Lightning Fast Processing
Our tool processes images locally in your browser using modern Web APIs. This means no slow uploads to a server and no waiting in queues. Get your optimized images in seconds.
Privacy & Security
Your privacy is our priority. Since all processing happens client-side, your images never leave your computer. This makes it the perfect tool for sensitive or confidential documents.
Powerful Batch Mode
Need to optimize hundreds of images? No problem. Our batch processing engine handles multiple files simultaneously, applying your chosen quality settings to all of them at once.
Choosing the Right Format
JPEG (Joint Photographic Experts Group)
Best for photographs and complex images with many colors. JPEG offers excellent compression but uses "lossy" compression, meaning some data is lost each time you save.
WebP (Modern Web Format)
A modern image format that provides superior lossless and lossy compression for images on the web. WebP images are typically 25-35% smaller than JPEGs of comparable quality.

Frequently Asked Questions
Does reducing quality damage the original image?
No, our tool creates a new optimized version of your image. Your original files remain untouched on your computer.
What is the best quality setting for the web?
For most websites, a quality setting between 70% and 80% provides the best balance between file size and visual clarity.
Are there any file size limits?
We support files up to 10MB each. For larger files, the processing might take longer depending on your browser's performance.
Can I process transparent images?
Yes, if you use the WebP format. JPEG does not support transparency and will replace transparent areas with white.
How much can I reduce file size?
Typically, you can reduce image file size by 50-80% with minimal loss in visible quality, especially when converting to WebP.
Is my data safe?
Absolutely. All processing is done locally in your browser. Your images are never uploaded to any server.
Pro Tips for Image Optimization
Use WebP for Modern Browsers
WebP offers significantly better compression than JPEG while maintaining better quality. It's now supported by all major browsers.
Resize Before Quality
Always resize your image to the exact dimensions needed before adjusting quality. This results in the most efficient file size.
