How to Make DIY Photocards at Home with pocaprint (Step by Step)

2026-10-18 · Hwani Studio

pocaprint is a small browser tool that turns your images into a print-ready PDF sheet of 55×85 mm photocards. It adds a 3 mm bleed, crop marks, optional cut lines and a rounded-corner guide, and it lays the cards out for A4 or US Letter paper. Everything happens inside your browser: images are not uploaded to a server. This guide walks through the whole process, from picking images to cutting the finished cards.

Before you start

Images you have the right to use. Your own photos, your own artwork, or images whose license allows printing. pocaprint is for personal, non-commercial use and is not affiliated with any agency, label or artist.
Resolution. For a sharp 300 dpi print, each card needs roughly 720×1075 pixels after cropping. Most phone photos are far larger. Images saved from chat apps are often compressed, so use originals when you can. See the resolution guide (Korean) for the math.
Paper. Photo paper or 200–300 gsm cardstock that your printer supports. Check the maximum paper weight in your printer's spec sheet.

Step 1: Add images

Drop images onto the page or use the file picker. Each image becomes one card tile. The order of the tiles is the order on the sheet.

Step 2: Adjust the crop

The card area including bleed is 61×91 mm, an aspect ratio of about 0.67. If your image has a different shape, pocaprint fills the card and crops the overflow, keeping the centre by default. Drag a tile to choose which part stays, and use the zoom slider to make the subject larger. The shaded band around the edge of each tile is the 3 mm bleed that will be trimmed off, so keep faces and text out of it.

Step 3: Choose the paper

Pick the paper that is actually in your printer. A4 fits 9 cards in portrait (3×3). US Letter fits 8 cards in landscape (4×2), because Letter is about 18 mm shorter than A4 and a third row does not fit with bleed and margins. If you have fewer images than slots, pocaprint repeats your images to fill the page, or you can leave the extra slots blank. More images than slots simply add pages.

Step 4: Pick the guides

Crop marks: short lines in the outer margin that show where to cut. They never touch the card.
Cut lines: thin grey rectangles on the card edge. Helpful when cutting by eye; a slightly off cut may leave a trace.
Rounded corner guide (R3): a dashed pink outline with a 3 mm corner radius, to preview what a corner punch will remove.

Step 5: Export and print at 100%

Export the PDF and open the print dialog. The single most common problem is the viewer shrinking the page with "Fit to page" or "Shrink oversized pages". Choose Actual size or a custom scale of 100, and turn off borderless printing. Each sheet has a 50 mm ruler in the bottom margin labelled "this line = 50 mm". Print one test sheet on plain paper and measure it. If it reads 48 mm, the page was scaled to about 96%. The actual-size printing guide (Korean) lists the settings for Chrome, Acrobat Reader and macOS Preview.

Step 6: Cut

Let the ink dry completely.
On a cutting mat, line a metal ruler up with matching crop marks at the top and bottom of the sheet and cut all the vertical lines first.
Turn each strip and cut along the horizontal marks. Neighbouring cards are 6 mm apart (3 mm bleed each), so each gap needs two cuts.

Step 7: Round the corners

A corner rounder punch gives the most consistent result. R3 to R5 looks natural on a 55×85 mm card. If you plan to laminate, laminate first and round the corners afterwards so the film does not lift.

Troubleshooting

Cards are slightly small: the print was scaled. Re-check the 100% setting in both the viewer and the printer driver.
White hairline on one edge: the cut drifted outside the bleed or the paper fed at an angle. Adjust the paper guides and cut from the crop marks, not the cut lines.
Blurry prints: the source image is too small after cropping and zooming. Use the original file or zoom out.
