Frequently Asked Questions
How does lossless compression reduce file size without losing quality?
Lossless compression removes redundant metadata (EXIF, color profiles) and optimizes internal DEFLATE and Huffman tables without modifying visible pixel values.
Are my photos uploaded to any external server?
