Mosaic HighRes

Pick one photo as the target and a pool of photos from your library, and Mosaic HighRes arranges small versions of the pool photos into tiles that recreate the target — zoom in and you see individual photos, zoom out and you see the whole picture. Built for actual prints, not just a screen: choose a physical size and DPI, see the per-tile sharpness before you render, and the renderer composites the output one strip at a time so it can produce genuinely large files without crashing a phone.

• No account, no sign-up, no login.
• No photo ever leaves your device — there is no server.
• No analytics, no ads, no trackers.
