BigPic vs GridyPrintX

BigPic turns one photo into a grid of tiles — then rebuilds it as one big picture. Print it as a seamless poster, or post the tiles to your feed so they reassemble into the full image on your profile grid. WHY BIGPIC • Split any photo into a grid, from 2×2 up to large layouts. • Seamless poster printing that survives the photo lab: every tile prints at the paper's exact size with a trim margin and corner crop marks, so the pieces line up perfectly. • Export a multi-page PDF at true, pixel-accurate size for print shops. • Post-ready grids: save every tile in the right order for an Instagram-style 3×3 that rebuilds your photo. FEATURES • Presets for Square, 4×6, 5×7, 6×8, 8×10, US Letter, A3, A4, and A5 — or set a custom aspect ratio. • Built-in cropping and fine position control. • Live cut-line preview with framing and trim-margin controls. • Share a single tile or all of them at once. PRIVACY BigPic works entirely on your device. No account, no cloud, no data collection — your photos never leave your iPhone. BigPic is free to start. Upgrade to Pro with a one-time purchase to unlock larger grids — no subscription, ever.
