Free PDF Tools: Merge, Split, Compress, Sign | Morph

Morph's PDF tools are a suite of 46 single-purpose tools that run in your browser. Merge files, split one into pages, compress, rotate and crop, convert to and from Word, PowerPoint, JPG and HTML, edit text and images, sign, redact, unlock and protect, add page numbers or a watermark, compare two versions, and run OCR on a scan. Every tool opens from one hub, works without an account, and processes the PDF on your device — nothing is uploaded.

Why a PDF tool should not upload

A PDF is usually the document that matters: a contract, a statement, a medical record, a manuscript. The typical "free online PDF tool" takes that file to a server, works on it there, and keeps it for a while. Morph parses and rewrites the PDF inside the browser tab. You can turn off your connection after the page loads and merge, compress or sign exactly as before, which is the simplest proof that the file never left.

What is in the suite

Organise — merge, split, extract pages, reorder, rotate, crop, delete pages, add page numbers.
Reduce — compress with a quality setting, flatten forms and annotations.
Convert — PDF to Word, PowerPoint, JPG, PNG and text; Word, images, HTML and Markdown to PDF.
Edit — change text and images, annotate, fill forms, add a watermark.
Secure — sign with a drawn or typed signature, redact for good, encrypt with a password, unlock a file you own.
Read — OCR a scanned PDF into searchable text, translate a document, compare two versions side by side.

How it works

The suite is built on pdf-lib and pdf.js compiled for the browser, with OCR from an on-device model. Each tool lives at its own URL (morph.cool/pdf/merge, /pdf/compress, /pdf/sign …) so you can bookmark the one you use.

使用方法

Open the PDF hub — Go to morph.cool/pdf-tools. Search the 46 tools or pick one — merge, split, compress, sign, convert.
Place your PDF — Drop the file onto the tool, or several for merge and compare. It is read on your device; nothing is uploaded.
Set the options — Choose the page range, the compression quality, the output format, or draw your signature — each tool shows only its own controls.
Run it — Press the action button. The PDF is parsed and rewritten in your browser; most files finish in seconds.
Save — Download the result to your disk. Open another tool from the hub to keep working on the same file.
