Step 2 — Upload Photos and Choose a Grid

For standard A4, pick a grid by photo count:

  • 2×3 — 6 photos, two rows of three
  • 3×2 — 6 photos, three rows of two
  • 3×3 — 9 photos, dense grid

Tap each cell and upload a shot. Move and scale inside the cell — double-click to edit.

Step 3 — Add a Frame (Optional)

For print, neutral frames work well:

  • White Classic — thin white gap between photos
  • Black Modern — bold contrast
  • No Frame — photos edge to edge

For formal documents and presentations — White Classic or no frame.

Step 4 — Download PNG or PDF

Click Export and pick format and quality:

  • PNG / Print — max resolution (~4800 px on the long side). Home or print shop.
  • PDF — professional printing. A4 page with correct proportions.
  • PNG / Web — smaller file for preview or sharing.

The export dialog shows final pixels and approximate file size before download.

How to Print a Collage at Home

After download:

PNG: open in your photo viewer (Photos on Windows, Preview on Mac). Print → A4 → "Fit to page."

PDF: open in Adobe Reader or a browser. Print → "Fit to page" → A4. PDF scales content to the sheet.

Use matte or glossy photo paper 200–300 g/m² for much better results than office paper.


Collage for Photo Lab Printing

If you order prints at a lab — confirm required resolution (usually 300 DPI) and pixel size. Download PNG — lossless, labs accept it easily.

For standard A4 at 300 DPI you need 2480×3508 pixels. Export with Print quality — the editor provides enough resolution.


A3 Collage for Printing

A3 (297×420 mm) is twice A4. Used for:

  • Posters
  • Large family collages
  • Wall displays

Same workflow — pick a grid, download PNG or PDF. Tell the print shop 297×420 mm for A3.
