You have your designs ready. Now the practical question: how do you actually get them onto the major platforms and set up for sales? Each platform has its own workflow, file requirements, and quirks. This guide covers the essentials for Redbubble, TeePublic, and Printify — the three platforms most independent designers use first.

Redbubble Upload Guide

Redbubble is the most beginner-friendly of the three. It has an active marketplace with millions of buyers and handles everything from fulfillment to customer service.

File Requirements

  • Format: PNG with transparent background (strongly recommended)
  • Resolution: 300 DPI minimum, higher is better
  • Size: At least 2400 x 3200 pixels for apparel; larger for home products
  • Color mode: RGB

Upload Process

  1. Log into your Redbubble account and click “Add New Work”
  2. Upload your PNG file
  3. Write your title (60-80 characters, include keywords)
  4. Add a description with natural keyword usage
  5. Add tags — Redbubble allows 15 tags, use all of them with specific, relevant terms
  6. Choose which products to enable and adjust the artwork placement on each
  7. Set your markup percentage (Redbubble handles the base price; your markup determines your profit)
  8. Publish

Tips for Redbubble

  • Enable your design on as many product types as makes sense — wall art and stickers sell well alongside apparel
  • Check placement carefully on each product type before publishing
  • Tags are critical for discovery — research what successful listings in your niche use

TeePublic Upload Guide

TeePublic is owned by Redbubble but operates as a separate marketplace. It focuses more narrowly on apparel and has a strong community of buyers who follow specific artists.

File Requirements

  • Format: PNG with transparent background
  • Resolution: 300 DPI, minimum 2000 pixels wide for apparel
  • Color mode: RGB

Upload Process

  1. Click “Start Selling” in your TeePublic dashboard
  2. Upload your design file
  3. Add your title and description
  4. Add tags (up to 20 are allowed)
  5. Preview the design on each product type
  6. Choose your price tier (TeePublic has fixed tiers rather than custom markup)
  7. Click “Upload My Design”

Tips for TeePublic

  • TeePublic runs regular promotional sales that temporarily lower prices — your commission adjusts accordingly
  • The platform favors designs with strong tag coverage, so research tags carefully
  • TeePublic has a strong gifting season in November-December; have your designs uploaded well before then

Printify Upload Guide

Printify is different from the marketplace platforms. It is a fulfillment network that connects to your own store — typically Shopify, Etsy, or WooCommerce. You control the storefront and customer experience.

File Requirements

  • Format: PNG with transparent background
  • Resolution: 300 DPI minimum
  • Size: Varies by product — the Printify design tool shows required dimensions for each blank
  • Color mode: RGB

Upload Process

  1. Log into Printify and click “Create Product”
  2. Select your blank (the shirt, mug, poster, etc.) and your print provider
  3. In the design tool, upload your file and position it on the product
  4. Use the mockup generator to create product photos
  5. Write your product title and description
  6. Set your retail price (Printify shows the base cost; your margin is the difference)
  7. Publish to your connected store

Tips for Printify

  • Choose your print provider carefully — base quality and shipping times vary by provider
  • Order a sample before listing widely, especially for apparel
  • The mockup photos matter enormously for Shopify conversion rates — use lifestyle mockups when possible

General Best Practices Across All Platforms

Batch your uploads. Set aside dedicated time for uploads rather than doing one at a time. The workflow becomes faster with repetition.

Keep a design inventory spreadsheet. Track which designs are on which platforms, what product types are enabled, and what revenue each is generating. This becomes important as your catalog grows.

Revisit underperforming designs. If a design has been live for 60 days without a sale, review the tags and description. Sometimes a title change makes the difference.

Think about the full product catalog. A design that works on a shirt often works on a mug, a tote, or a wall print. Enable the products that make sense for each design.

Getting your designs onto all three platforms creates multiple passive income streams from the same creative work. The upfront effort of a thorough upload pays dividends every time one of those listings converts.
