FAQs
Why does image quality decrease after compression?
Image compression reduces file size by removing color information and details. Moderate compression achieves a balance between quality and size.
What's the maximum image file size supported?
This tool processes images in your browser, theoretically no size limit, but we recommend keeping individual images under 50MB for best experience.
Does compression compromise image privacy?
Not at all. All processing happens locally in your browser, images are never uploaded to any server.
Can I restore the original image after compression?
Compression is irreversible. We recommend backing up important original files before compression.
Is there a limit for batch compression?
Maximum 20 images per batch to ensure stable browser performance and optimal user experience.
Will image metadata be preserved?
Canvas-based compression does not preserve EXIF metadata. The tool focuses on visual quality and file size reduction.
