Printables studio
QR codes, calendars, labels, puzzles and posters — print-perfect PDFs in seconds.
Printshop makes things to print: QR codes and barcodes, Wi-Fi guest cards, calendars in 17 languages with week numbers and public holidays, label sheets filled from a CSV file, graph and music paper, posters tiled over ordinary sheets, folded booklets and, with Puzzle Press, sudokus, mazes, word searches, crosswords, nonograms and maths worksheets with answer keys. Every printable is a true-size vector PDF with a test square, plus SVG and PNG, made in your browser.

Features
Standards-true QR codes
All 40 versions and the four error-correction levels, the shortest mix of numeric, alphanumeric and byte modes, all eight masks scored — checked against an independent decoder.
Wi-Fi guest cards
Network name and password become a scan-to-join code on 1, 2, 4 or 8 cards per page. The password never goes into share links.
EAN-13, UPC-A and Code 128
Check digits calculated or verified, GS1 sizes and quiet zones, and Code 128 that switches between code sets for the shortest barcode.
Calendars in 17 languages
One month per page or the year on one sheet, month and day names from CLDR, right-to-left Arabic, and the first weekday of your region.
Week numbers and holidays
ISO 8601 or US week numbers and public holidays for 16 countries and their regions, 2024–2030, printed right in the day boxes.
Label sheets with mail merge
Fill address labels, name badges or jar labels from a CSV file with {Column} placeholders, on generic sheet layouts or your own measurements.
A code on every label
Add a QR code, Code 128 or EAN-13 barcode built from each row — product labels, asset tags and tickets in one go.
Graph, dot, isometric, hex and music paper
Exact spacing in millimetres, major lines, a name and date line, writing lines with a margin and staff paper — up to 50 pages.
Posters from ordinary sheets
Enlarge a photo across many pages with overlap, trim lines, crop marks, tile names and an assembly map, and see the resolution you will get.
Fold-and-staple booklets
Notebooks, pocket calendars or photo zines imposed in saddle-stitch order with creep compensation, page numbers and fold marks.
True-size PDF, SVG and PNG
Vector PDFs with embedded font subsets, SVG for editing and PNG for sharing — every page with a test square or scale bar to check the printer.
Live preview
Every change redraws the real pages at once: zoom, flip through pages and see warnings — low contrast, tiny modules, cut text — before you print.
Projects, history and sharing
Autosave with recent projects, undo and redo, project files with images, Google Drive, and share links that leave out passwords, contacts and CSV rows.
Puzzle Press: sudoku, mazes and nonograms
Sudokus from 4 × 4 to 16 × 16 with one proven solution and an honest difficulty grade, mazes in squares, hexagons, circles or a heart, and picross from your own drawing.
Word puzzles and maths worksheets
Word searches and criss-cross crosswords from your own words in any script, and maths sheets with variants A, B, C for a class — always with answer keys, and playable on screen.
Thirteen tools for AI agents
QR codes, barcodes, calendars, label sheets, paper, posters, booklets and the six puzzle makers as tools with a JSON API and MCP, built on the same engine as the app.
Templates
Start from a ready-made project and change it to fit.
QR code for a link

Frequently asked questions
Will my printout have the right size?
Yes, if you print at 100 % (“actual size”) and not “fit to page”. Every PDF has a test square or a 10 cm scale bar: measure it after printing. Printers can still be off by a fraction of a millimetre.
Do the QR codes work with every phone?
They follow ISO/IEC 18004 and were checked with an independent decoder for all versions, levels and masks. Keep the quiet zone, use dark on light, keep modules above about 0.33 mm and test a print with your audience’s phones.
Is my Wi-Fi password safe?
Printshop makes the code in your browser; nothing is uploaded for the app. The password is stored only in this browser’s project and in project files you save. Share links never contain it, so the receiver has to type it in again.
Which label sheets are supported?
Any sheet: choose one of the generic layouts (named by size, for example A4 3 × 8 70 × 37 mm) or enter the measurements from the sheet’s package — page size, columns, rows, label size, margins and pitch. Print a test on plain paper first.
Where do the holidays come from?
From the public-holiday data of the RuleDate tool (Nager.Date, MIT licence) for 16 countries, 2024 to 2030, with regional holidays when you enter a region code such as DE-BY. School holidays are not included.
Can I make barcodes for products in shops?
You can print EAN-13 and UPC-A for numbers you own. Retail product numbers must be licensed from GS1; a barcode alone does not register a product.
How do I print a booklet?
Download the booklet PDF and print it double-sided, flipping on the short edge. Stack the sheets in order, fold them in the middle and staple along the fold. Check the first sheet before printing all.
Do the sudokus really have only one solution?
Yes. A clue is only removed when a solver proves that exactly one solution remains. The printed difficulty is measured: it names the hardest technique a person needs, from singles (easy) to X-wing (hard).
Can I make a new set of puzzles with the same settings?
Change the seed (or press “New puzzles”). The same seed and settings always give the same puzzles, so a share link or a saved project prints exactly the sheet you made.
Can my class get different worksheets?
Yes. Maths worksheets come in up to six variants (A to F) with the same kind and difficulty of problems but different numbers, and every variant has its own answer key.
Can an AI agent make these printables?
Yes. The thirteen Printshop tools — including sudoku, maze, word search, crossword, nonogram and maths worksheet — have a JSON API and MCP and return the PDF, SVG and PNG plus a link that opens the result here for editing.
Limitations
What Printshop does not do (yet):
- Printshop prints its own printables; it does not import or impose existing PDF files.
- QR codes use numeric, alphanumeric and byte (UTF-8) modes; Kanji mode, Micro QR, structured append and GS1 QR are not supported.
- Barcodes: EAN-13, UPC-A and Code 128 (ASCII) only; no EAN-8, add-ons, GS1-128 application identifiers, Data Matrix or PDF417.
- Chinese, Japanese and Korean text uses small font subsets with calendar words and common characters; other CJK characters fall back to English labels or are missing from the PDF.
- Holidays cover 16 countries for 2024–2030; school holidays and local observances are not included.
- Images for posters and booklets must be JPEG or PNG; the PNG preview of a tile shows grey boxes instead of the photo, and very large images make big PDFs.
- Colours are sRGB; there is no CMYK, bleed or spot-colour output for professional print shops.
- Puzzle Press makes classic sudokus only (no killer, jigsaw or diagonal variants yet); 16 × 16 grids have a time budget and may keep a few extra clues.
- Crosswords are criss-cross puzzles built only from your words; there is no dictionary fill for dense newspaper-style grids. Nonograms are black and white.
- Word puzzles in Chinese, Japanese or Korean print only characters in Printshop’s small font subsets; missing characters are reported.
