Supplement Packet Builder: combine estimate, supplements, and photos into one carrier-ready PDF

Free in-browser tool that combines an original estimate, supplements, and photo PDFs into one carrier-ready packet for collision repair shops. No upload, no signup, no email gate. Files never leave your computer. The entire merge happens locally in the browser via WebAssembly.

How collision shops use it

Adjusters expect a single PDF, not a chain of email attachments. The convention most carriers prefer: original estimate first, supplements in submission order, then any photo sheets at the end. Build the packet in that order, name it after the claim number, and attach to one email thread. Average shop saves 5 to 10 minutes per packet versus building the same thing manually with Adobe or Preview.

Why the privacy story matters here

This tool runs entirely in the browser via WebAssembly. No file ever uploads to a server. The merged PDF is assembled locally and saved to the user's downloads folder. There is no privacy review needed before using it on real claim files. Most online PDF tools upload your files; this one does not.

Common questions

Does this work for non-PDF files?

PDFs only. If your photos are JPGs, drop them into a one-page PDF first (most phones can do this from the share sheet). The reason: combining heterogenous file types reliably is a server-side problem, and the whole point of this tool is to keep claim files off any server.

Is there a file-count limit?

No hard cap. We have tested up to 30 input PDFs at 50 MB each in modern browsers. Performance scales with available memory. If your packet is unusually large, build it in two halves and merge those.

Where do my files go?

Nowhere. The merge happens entirely in your browser. Your input PDFs are read into memory, the output PDF is built in memory, and the result downloads to your computer. Closing the tab clears everything. No server, no logs, no analytics on the file content.
