Frequently Asked Questions
Will my images be saved on a server?
No, all merging and compression operations are performed locally in your browser. No data is uploaded.
Is there a limit on the number of images?
We recommend merging no more than 20-30 images at a time to prevent your browser from running out of memory.

Technical Background
We use HTML5 Canvas to render and combine the images, and leverage native browser APIs alongside upng-js (for PNGs) to provide efficient, high-quality local compression.
