Three things to do with the file you downloaded: get it into Canva, swap in your own photos, and download something a printer can use. Everything here works on a free Canva account.
Prefer to watch? Here's the whole thing in just over two minutes.
1. Upload it to Canva
The file is a PowerPoint (.pptx), which Canva imports as an ordinary design.
In a browser: go to canva.com, open Uploads in the left-hand rail and drag the file in — or use Create a design → Import file.
In the Canva desktop app: the same, Uploads → Upload files.
Then open it: click the … on the uploaded card and choose Open in a new tab.
Don’t click the thumbnail itself. In Canva, clicking an uploaded design’s thumbnail inserts it into whatever design you already have open. The … menu is the safe route.
A collage with a few hundred photos is a big file and can take a few minutes to import. Wait for the page thumbnail to appear before you start editing.
Don’t use Canva’s Resize on the design. The size that arrived is the size your print needs.
2. Put your own photos in
Upload your photos first. Uploads → Upload files, and select them all at once. Use the largest, original files you have — not versions that have been through a messaging app. Canva keeps as many pixels as the print needs, so the sharpness of the finished piece is set by the photos you feed it.
Then drag each photo onto a cell. Drop it directly on top of an existing sample photo. It snaps into that cell and takes its shape and crop automatically.
- Dropped in the wrong place? A photo that lands on blank canvas becomes a full-page image over everything. Press Ctrl+Z (⌘Z on Mac) and try again, aiming at the middle of a cell.
- Fix the crop: double-click a photo to reposition and zoom it inside its cell, then click outside to finish.
- Small cells: on word and number collages the cells at the edges of each letter are tiny. Zoom in (Ctrl +) before dragging.
- Leave the cells alone. Moving or resizing a cell breaks the arrangement. Change what is inside them, not where they are.
- Text — a title, a name, a date — edits exactly like any Canva text box: click it and type.
Replace every sample photo. The pictures already in the template are low-resolution stand-ins, there only to show the layout. Any sample left in place will print blurry, so every cell needs one of your own photos before you download.
Borders stay. On Polaroid scatter and Masonry, matted, the little border around each photo stays in place when you drop your own picture in. Every other template, the cut-out shapes included, keeps its outline too.
3. Download it for printing
Share → Download, then set two things:
- File type: PDF
- Presets: Print — not Digital, which is what Canva offers first.
Then Download. That combination is the only one that keeps print quality.
| Choice | Use it? |
|---|---|
| PDF + Print preset | Yes. Full resolution, exact size. |
| PDF + Digital preset | No — downsampled for screen viewing. |
| PNG or JPG | No. These come out at 96 DPI whatever the size, far too coarse to print. The upscale slider that would fix it is a Canva Pro feature. |
Switching to Print changes the panel, which is how you know it took: the Compress PDF toggle disappears and a Color profile dropdown appears. Leave it on RGB — CMYK is Pro-only, and printers convert from RGB as a matter of course. Crop marks and bleed sit under Advanced Settings, below it; leave them off unless your printer has asked for them.
What to tell the printer: print the PDF at 100% / actual size, and not “fit to page” or “shrink to fit”. The PDF already carries the exact physical dimensions of your order.
A quick check before you send it
- Every sample photo has been replaced with one of yours — none left behind.
- No photo is sitting loose on top of the layout (press Ctrl+Z if one is).
- The page count is still 1.
- The preset was on Print, not Digital. Open the PDF and zoom right in on one photo to confirm: if it looks soft at full magnification, the wrong preset was used.
Two sizes that need a word
Square sizes open slightly off-square, on purpose. A 24 × 24″ order opens in Canva as 24 × 24.25″, a 20 × 20″ as 20 × 20.21″. Canva flattens any exactly-square import to its 1080 × 1080 social-media preset, and a free account can’t undo that, so the design arrives a hair off square to stop it happening. The extra sliver is blank paper, split evenly top and bottom, with your collage centred in it. Ask the printer to trim to the square size you ordered — or just leave it; it is a quarter of an inch.
40 × 60″ imports at 93% of full size. A PowerPoint file cannot declare a page larger than 56 inches, so this one size arrives as 37.3 × 56″. To get the size you ordered, tell the printer to print the PDF at 107%. Nothing about the collage itself is affected — it is purely the declared page size.
Still stuck?
Tell us the size, the template, and what Canva did. A screenshot of the File menu showing the design’s dimensions is usually enough for us to sort it out.
