Frequently Asked Questions
How does the 'Target KB' compression mode work?
Our in-browser engine uses an iterative binary search algorithm to compress image bytes and gently scale dimensions if necessary, ensuring the final file is strictly under your target limit (e.g., ≤ 20 KB or ≤ 50 KB).
Does this tool preserve or inject 300 DPI for print and exam portals?
Yes! When enabled, our engine modifies JFIF and PNG header chunks directly in browser RAM to embed a clean 300 DPI resolution tag without modifying file visual data.
Can I remove camera EXIF and GPS metadata?
Yes. The built-in privacy stripper removes all camera models, GPS geolocation coordinates, and timestamps, reducing file size by an extra 5 to 15 KB.
Can I resize pixel dimensions while compressing?
Yes. You can specify exact custom Width and Height pixel dimensions with an aspect-ratio lock, or scale by percentages (75%, 50%, 25%).
Are my files safe and private?
100% safe. All calculations execute client-side in your device's browser memory (RAM). No photo data is ever sent to or stored on any external server.
