PDF Tools – Free Online Editor, Converter & eSign

What's in this category?

Most users start with the structural tools. PDF Merge drops any number of PDFs into a single file in your chosen order — useful for combining a cover letter, CV and references into one application package. PDF Split does the opposite: extract a single page or a range, perfect for grabbing the bank-statement page you actually need from a 30-page download. Compress PDF recompresses embedded images and strips metadata to shrink large files for upload limits.

The format converters cover the most common conversions. PDF to Word exports a clean editable .docx so you can change text without retyping; PDF to Excel detects tables and exports a real .xlsx — a huge time-saver for invoices, statements and price lists; PDF to JPG turns each page into a high-quality image at the resolution you choose, ideal for embedding pages into a slideshow or a web page.

Two finishing tools round things out. PDF Watermark adds a custom text or image watermark on every page with adjustable opacity and position — for "Draft", "Confidential" or your company logo. eSign PDF lets you draw, type or upload a signature, drop it onto the page and download the signed file — quick enough for routine contracts, NDAs and approvals.

How does browser-based PDF editing work?

The toolkit is built on Mozilla's pdf.js (for reading and rendering pages) and the open-source pdf-lib library (for merging, splitting, watermarking and eSign). Both run as JavaScript inside the page, so a 100-page contract is parsed entirely on your laptop or phone — never streamed to a third-party service. That means there are no upload size limits, no waiting in a queue, and no copy of the file lingering on a remote server. For sensitive documents — banking statements, legal contracts, payslips, medical records — that's the only safe approach.
