BigPic vs Postly

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.

Want a big wall poster but only have a regular home printer? Postly splits one photo across several Letter or A4 pages so you can print them, trim and tape them together into a large poster. Pick a photo, choose a grid and paper size, and tap Create Poster PDF. You get one multi-page PDF — one tile per page — ready to print, share or save to Files. • FIVE GRIDS — 2×2 (4 pages), 3×3 (9 pages), 4×4 (16 pages), plus 2×3 and 3×2 (6 pages) for tall or wide posters. • LETTER OR A4 — each tile prints on its own US Letter (8.5 × 11 in) or A4 sheet. • CUT MARKS ON EVERY PAGE — corner marks show exactly where to trim each tile. • OPTIONAL OVERLAP — add 0.25" or 0.5" of overlap on inner edges, with dashed guides, to make lining up and taping neighboring sheets easier. • NUMBERED TILES — every page carries a small label with its page number and column/row position, so assembly is easy. Page 1 is the top-left tile. • SHARE OR SAVE — print with AirPrint, or send the PDF to Files, Mail or a print shop. Honest scope: Postly makes one poster from one photo at a time. Each tile is scaled to fit its portrait page inside a 0.5" margin, so the finished poster is a little smaller than the pages laid side by side. Big grids enlarge the photo a lot, so start with a sharp, high-resolution photo. Your photo is processed on your iPhone. Nothing is uploaded and no account is needed. Try it free — 3 poster PDFs.
