Documentation
How the customizer works.
Install, build templates, ship custom products. The pages below cover everything from your first template to the print-ready file that lands in your fulfilment bucket.
Category
Getting Started
Install the app and ship your first customizable product.
Quickstart
From install to your first customizable product live on your store. About five minutes of work.
Installing Pixel Wrangler
What the install actually does, the permissions it asks for, and how to confirm the customizer is live on your storefront.
Switching from another customizer
Moving from another customizer: what to capture first, how placeholders map, matching print specs, running both apps at cutover, briefing fulfillment.
Will a product customizer slow down your Shopify store?
What a customizer adds to a Shopify product page: Pixel Wrangler is a theme app extension with one deferred script, no injected code. Measure it yourself.
Category
Building
Templates, canvases, placeholders, and the customer-facing customizer.
Templates 101
What a template is, the pieces it's made of, and how it connects to a Shopify product.
Text placeholders
Configure text slots customers fill in — fonts, colours, sizing, character limits, stroke and shadow.
Image, sticker, background, and mask placeholders
The four non-text placeholder types — what they do, when to use each.
Sides and output files
Front, back, sleeves, mugs that wrap — and the print-ready files Pixel Wrangler ships to your fulfilment partner.
Surcharges and Spend & Save discounts
Charge more when a design costs more to print, and nudge customers toward bigger orders with tiered discounts.
The storefront customizer
What your customer actually sees and does — from clicking Customise to landing in cart.
Styling the customizer — Brand & Language
Make the customizer look and sound like your store — colours, layout, every customer-facing string.
A tour of the template builder
The builder workspace — the canvas, the layers panel, the toolbar, and the preview — and where each control lives.
Category
Order Flow
What happens after a customer buys — files, emails, fulfilment.
Order flow — what happens after checkout
From paid order to print-ready file in your fulfilment hands.
Print-ready files: specs, naming, per-side outputs and fulfillment hand-off
What renders on every order: format, size, DPI, color and bleed, per-side file naming, and how to hand files to your own line, a partner or a POD supplier.
Customizing order confirmation emails
Display custom product thumbnails and preview links in your Shopify order confirmation emails.
Editing a customer's design on an order
Fix a typo or a slipped image on a placed order, regenerate the print artwork, and keep the customer's original safe.
Line item properties reference
Every _pw_ property Pixel Wrangler attaches to cart lines, and the Settings presets that control which ones appear.
