Web-to-print without the recreation tax

Use the file you already have.

StackFill turns your existing print PDF into a fillable, on-brand template. Mark which fields are editable, lock the rest, and hand customers a link. They personalize. They pay. You get back final print output built from your approved artwork.

Built for press-critical PDFs: CMYK-aware, trim/bleed-aware, and designed to preserve locked artwork where supported.

  • CMYK
  • Trim & bleed
  • PDF/X-1a
  • Preflight

Visual proof

Three steps from approved file to printed output.

  1. SF YOUR SHOP First Last Title here (305) 000-0000 first@yourshop.com

    1 · Approved PDF

    Start with the file your shop already approved for press. No rebuild, no design tool.

  2. SF YOUR SHOP First Last Title here (305) 000-0000 first@yourshop.com

    2 · Editable fields

    Mark only the customer-safe text, selection, or image fields. Lock the rest in one toggle.

  3. SF YOUR SHOP Jane Cooper Director, North Region (305) 555-0142 jcooper@yourshop.com

    3 · Personalized output

    Customer fills the link or the embedded widget. You receive final print-ready output built from the locked template.

Upload your master file

Drop in a finished print PDF — business cards, letterheads, badges, postcards. StackFill is designed around press-critical artwork, including trim and bleed metadata where the source PDF and renderer support it.

Mark what's editable

Click the fields a customer should fill — name, title, phone — and lock everything else with one toggle. Set fonts per element or one default for the whole stack. Brand stays exactly on-brand.

Send a fill link

Hosted by us, or embedded white-label on your site. Customer types in fields, previews against your design, optionally pays, and final output is generated from the locked template.

Hosted fill links

Send a customer a StackFill link. They personalize and receive output based on access rules.

Storefront embed

Drop StackFill into a product page. The customer personalizes before checkout; your store receives a fill ID.

Built for the trade

Print shops still editing every variant by hand. Corporate marketing teams spinning a hundred badges off one master. Agencies sending personalization links to clients instead of versioning by hand. One template feeds one customer or a thousand — same engine.

The renderer path is built for print-production concerns like CMYK-aware output, trim boxes, registration marks, and preflight feedback. No headless-Chromium page capture tricks.

What's not StackFill

  • Not a design tool — you don't create artwork from blank canvas.
  • Not an e-sign or generic PDF form — we produce print-grade CMYK collateral.
  • Not a storefront or print MIS — we drop into the one you have.
  • Not a template marketplace — your file is the template.
