Frequently Asked Questions

Which image formats can I compress?
You can compress JPG/JPEG, PNG, and WebP images. Each format is optimized using its native compression algorithm for the best results.
Will compression reduce my image quality?
At 80% quality (the default), most images look virtually identical to the original while being significantly smaller. You can adjust the quality slider to find your preferred balance between file size and visual quality.
How much can I reduce my image file size?
Typical compression reduces file size by 40-80% depending on the original image and quality setting. Photos taken with modern cameras often see the largest reductions because they contain high-resolution data that compresses efficiently.
Is my image data secure?
Yes! All compression happens directly in your browser using the HTML5 Canvas API. Your images are never uploaded to any server. They stay on your device the entire time.
Can I compress multiple images at once?
Yes! You can upload up to 50 images at once (100MB total). After compression, you can download them individually or as a single ZIP file.
What does the 'Max Width' option do?
The Max Width option resizes images that are wider than the specified pixel width while maintaining the aspect ratio. This is useful for preparing images for the web, where full-resolution photos are unnecessarily large.
