Merge, split, convert, edit and secure PDF documents in the browser. Nothing you drop here is uploaded - the files are read by JavaScript on your own computer, the work happens on your own processor, and the result is handed straight back to you. There is no queue, no temporary copy on a server, and nothing for us to delete an hour later because there was never anything to delete.
No tool matches that. Try the category chips above, or tell us what you were looking for on the contact page - the build order is decided by what people actually ask for.
39 of these 39 tools are live right now, each one built on the same engine rather than bolted together from whatever library happened to be free that week. Every one of them shares the same architecture, and that architecture is the reason this page exists rather than another wrapper around somebody else's conversion API.
Almost every free PDF site works the same way. You choose a file, the browser posts it to a server, a worker process runs a command line utility on it, and a download link comes back. It works, it is cheap to build, and it means a stranger's machine held your document. For a birthday party invitation nobody cares. For a signed contract, a payroll export, a medical scan, or a supplier price list, that is a data transfer you did not intend to make and cannot audit.
The tools on this page do the work in your browser instead. The file is opened with the File API, parsed in memory by a PDF library running as JavaScript on your own processor, and written back out as a Blob your browser downloads from itself. There is no request carrying your document, because there is no server-side step to send it to. You can verify that claim without trusting us: open your browser's network panel, run any tool here, and count the requests. The only one you will find is the small call that counts your operation against the free allowance, and it carries a tool name and nothing else.
Client-side processing is not free of trade-offs, and any site that pretends otherwise is selling something:
The offline test. Open any live tool, let the page finish loading, then disconnect from the network entirely and use it. The file still processes and the download still works. That is not a demonstration of resilience, it is proof of where the processing happens.
Running these tools costs us almost nothing per operation, which is exactly why the allowance exists in the form it does. We are not metering compute, we are metering the one thing that has value here: the audience. The numbers are small, deliberately public, and identical on every tool in the suite.
| Tier | Operations | Files per batch | Batch size |
|---|---|---|---|
| Anonymous visitor | 1 per 12 hours | 20 | 100 MB |
| Free account | 2 per 12 hours | 20 | 100 MB |
| Premium | Unlimited | 100 | 500 MB |
An operation is one run of one tool, however many files went into it. Merging forty documents into one is a single operation, not forty. The window is a fixed 12 hours that opens on your first run, so the counter on the tool page always shows you exactly when it resets rather than making you guess.
Anonymous visitors are counted by network address, because that is the only identifier that survives a private browsing window. If you share an office connection with forty colleagues, you share the anonymous allowance with them too, and the fix is fifteen seconds of registration rather than an argument with a firewall.
CartHacker is a publication for people running online stores, and this suite exists because the same document problems keep appearing in that work. Supplier invoices arrive as twelve separate scans that need to be one file before accounting will look at them. Product photography needs to reach a printer as a paginated document rather than a folder of images. A signed distribution agreement needs its metadata stripped before it goes to a third party, because the Author field still says the name of a lawyer at the other company.
None of that justifies a monthly subscription to a desktop suite, and none of it should require handing a contract to a free website with an unclear privacy policy. That is the entire brief.
The build order is set by what people actually ask for. Tools marked Soon have a page, a specification and a place in the queue, and the fastest way to move one up that queue is to say so.
