Frequently Asked Questions
Are my photos uploaded to a server?
No. The KodiniTools Collage Maker processes all images exclusively locally in your browser. Your photos never leave your device and are never transferred to our servers. Fully GDPR compliant.
Can I also have the collage printed?
Yes — export the collage at high resolution (at least 2480×3508px for A4 at 300 DPI) and send the file to an online print service like Shutterfly, Snapfish or Vistaprint.
Which input formats are supported?
JPG, PNG and WebP — all common smartphone and camera formats are compatible.
How many images can I use in one collage?
Up to 9 images per collage depending on the layout. For larger mosaics, choose a layout with more slots.
Design tip: A white gutter (2–5px) between images looks clean and modern. A black background without gutter looks dramatic and is ideal for high-contrast photos. For Instagram grids, a consistent color tone across all images works best.
