Frequently Asked Questions
Are my photos uploaded to external servers?

Which image formats are supported?
Supported formats include standard JPEG, JPG, PNG, WebP, SVG, GIF, and modern image files.
Can I process multiple images in batch?
Yes! You can select and process multiple images simultaneously with high-speed parallel browser rendering.
Will image compression noticeably degrade visual quality?
Our smart compression algorithms remove invisible metadata and redundant color data, reducing file sizes by up to 80% with virtually zero perceptible loss in visual clarity.
Can I sharpen dim document photos for reading?
Yes! Increasing contrast while applying grayscale makes faint pencil or pen text legible.
