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 · Approved PDF
Start with the file your shop already approved for press. No rebuild, no design tool.
-
2 · Editable fields
Mark only the customer-safe text, selection, or image fields. Lock the rest in one toggle.
-
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.
