Frequently Asked Questions
How does image compression work?
Image compression reduces file size by removing redundant data and applying encoding algorithms. Lossy compression (JPEG, WebP) discards some visual information for smaller files, while lossless compression (PNG) preserves all data but achieves less size reduction.
What quality level should I use?
For web images, 70-85% quality offers a good balance between file size and visual quality. For printing or professional use, use 90-100%. For thumbnails or previews, 50-70% is usually sufficient.
Which format should I choose?
JPEG is best for photographs and images with gradients. PNG is ideal for images with transparency, text, or sharp edges. WebP offers the best compression but has limited support in older browsers.
Is my image data secure?
Yes, all processing happens directly in your browser using the Canvas API. Your images are never uploaded to any server, ensuring complete privacy and fast processing.
What's the maximum file size I can compress?
You can compress images up to 10MB in size. For larger files, consider using desktop software or resizing the image first.
