Pdfpix
Pdfpix helps you merge, split, compress, convert, organize, sign, protect, repair and inspect PDFs without sending them to a server. Each free tool runs in your browser, requires no account and has no usage cap. Before offering a download, the tool opens its result again, reads it back and compares it with your original. If verification fails, it refuses the output. Tools that rewrite text preserve its selectability instead of turning the document into page images. The 31 tools cover common jobs including page organization, image conversion, forms, password protection, metadata removal, redaction checks and print preflight.
