Merge, split, and watermark PDFs from your app with one API (no native libraries)

If you've ever had to merge a few PDFs, stamp a "CONFIDENTIAL" watermark, or turn a stack of images

into a single PDF on the server, you know the pain: pdf-lib, pdftk, ghostscript, native

binaries that won't install on your host, and an afternoon gone.

Here's a lighter option: a small HTTP API that does the common PDF jobs for you. You POST a file, you get

a PDF back. No dependencies, no native build steps, works from any language.

I'll show merge, watermark, and images-to-PDF with copy-paste examples in cURL and Node.

If you need image resizing/converting/compression too, there's a companion

Image Toolkit API with the same shape.

Built it because I kept re-writing the same PDF glue code. If you hit a rough edge or want an endpoint

that isn't there, drop a comment — I read them.
