Free online PDF toolkit
Most online PDF editors limit free use to a few files per hour, stamp watermarks on your output, or demand an account — and they upload your private documents to their servers to do it. This toolkit does everything locally in your browser using the open-source pdf-lib library, so your files never leave your device, there are no limits, and there is no sign-up. Merge several PDFs into one, extract or split pages, rotate pages, delete the ones you do not need, and convert images (JPG or PNG) into a PDF — all for free and all completely private.
How to use it, step by step
Pick a tab — Merge, Split / Extract, Rotate, Delete Pages, or Images → PDF. Drop in your PDF (or images for the last tab) by dragging onto the upload zone or clicking to browse. When a tool accepts more than one file, drag the file rows to set the order before you run it. Enter any page ranges where the option appears, then click the action button and your finished PDF downloads instantly. Nothing is sent over the network at any point.
Merging and combining
The Merge tab stitches multiple PDFs into a single document in the exact order you arrange them. It is the fastest way to combine invoices, contracts, scanned pages, or chapters into one file before sending. Because the order is controlled by dragging rows, you decide precisely how the final document reads — no re-uploading or re-running required.
Splitting and extracting pages
Split / Extract pulls exactly the pages you ask for out of a larger PDF. Type a range such as 1-3, 5, 8-10 to build a new document from those pages only. Leave the range blank and the tool bursts every page into its own separate PDF, packaged together as a ZIP download — handy when you need each page as an individual file. Page numbers are one-based, matching how your reader displays them.
Rotating and deleting pages
The Rotate tab fixes sideways or upside-down scans: choose 90° clockwise, 180°, or 90° counter-clockwise, and optionally limit the rotation to specific pages with a range like 1,3-5. Leave the page field blank to rotate the whole document. Delete Pages removes unwanted pages — a cover sheet, a blank back page, or a duplicate — and rebuilds the PDF from everything that remains. The tool will not let you delete every page, so you always end up with a valid document.
Turning images into a PDF
The Images → PDF tab converts JPG and PNG files into a single PDF, one image per page, each page sized to its image. Drop in phone photos, screenshots, or scans, drag them into the order you want, and click Create PDF. It is the simplest way to turn a pile of pictures into one tidy, shareable document.
Why local processing matters
Uploading a contract, medical record, or tax form to an unknown server means trusting that company with your private data. Here there is nothing to trust: the work runs in your own browser tab, offline-ready once loaded, and your files are never transmitted. That makes the toolkit safe for confidential material while staying fast, unlimited, and free.
