Free PDF Merge, Split & Rotate Tool
Combine PDFs, pull out specific pages, fix sideways scans, or turn photos into a single PDF - all on your own device. Your documents are never uploaded.
Runs entirely on your device. Your PDFs are processed in your browser and never uploaded. There is no server to send them to, so we never receive, store, or see your PDFs - and filenames are hidden from our analytics too. Load this page, disconnect from the internet, and it still works.
What do you want to do?
Up to 20 files, 100.00 MB total. Nothing is uploaded.Why a browser-based PDF tool matters for business documents
Most free PDF tools work by uploading your file to a server, processing it there, and handing back a download. For a holiday itinerary that is fine. For a signed contract, an invoice with bank details, a medical intake form, or an unreleased proposal, it means handing a third party a copy of a confidential document - and most of those services keep the file for hours so their queue can process it. This tool never sends the file anywhere. Merging, splitting, rotating, and image-to-PDF conversion all run inside your browser using the pdf-lib library, which loads as JavaScript on this page and does the work on your machine. There is no upload step, so there is no copy to delete and no retention window. It also means no file-count caps, no watermarks, and no waiting behind other people in a queue.
What each mode does
Merge combines several PDFs into one file, in the order you arrange them - use the arrows to reorder before merging. Split extracts the pages you name into a new document: type "1-3, 7, 10-" to keep pages one to three, page seven, and everything from ten onward. Rotate fixes pages that scanned sideways, in 90-degree steps, applied either to every page or only to the ones you list. Images to PDF turns a set of JPG or PNG files into a single PDF, one image per page at its native size - useful for turning photographed receipts or whiteboards into something you can email as one attachment.
Working with scanned documents and receipts
Phone cameras produce large images, and a stack of them makes an unwieldy email. Converting them to a single PDF keeps them together and in order. If the result is too large to send, run the images through our image converter first and set a max width of around 1600 pixels - text stays readable, and file size usually drops by 70% or more. Note that this tool does not run OCR: the text in a scanned page stays part of the image and will not be searchable or selectable.
Frequently Asked Questions
No. Every operation runs in your browser on your own device: no file data is transmitted, stored, or logged, and filenames are masked from our analytics. You can verify it: load this page, disconnect from the internet, and merge two PDFs - it still works, because there is no server involved.
Up to 20 files and around 100 MB in total per batch. The cap exists because your browser holds the documents in memory while it works, not because of any server limit. Very large files are slower on older machines but will still complete.
Files with an owner password (restricting editing) usually open. Files with a user password - where you need a password just to view the document - cannot be opened, because the content is genuinely encrypted. Remove the password in your PDF reader first.
Use commas for individual pages and hyphens for ranges: "2" is one page, "1-5" is a run, "8-" means page eight to the end, and "1-3, 7, 10-" combines all three styles. Leaving the field empty keeps every page.
Merging preserves each source document exactly, including embedded fonts and images, so the result is roughly the sum of its inputs. This tool deliberately does not re-compress your pages, because that is what degrades scanned text and images in other tools.
No. There is no OCR here - a scanned page stays an image inside the PDF. If you need selectable, searchable text, you need an OCR step, which is a different kind of processing.
Still Emailing PDFs Around?
Contracts, invoices, and intake forms handled by hand are a workflow problem, not a document problem. We automate the paperwork so it stops eating your week.
