PDF Tools

Merge, split, watermark, password-protect, compress, extract text, read metadata and convert pages to images — the PDF plumbing every product needs and nobody wants to build twice.

More PDF operations — HTML→PDF, split, watermark, compress

Watermark — stamp text or an image over every page — /watermark
Password-protect — encrypt a PDF — /protect
Compress — shrink the file size — /compress

Metadata — read a PDF's document properties — /metadata
To images — convert pages to PNGs (the demo below) — /to-images
