Why not just upload it?
Most free PDF tools are upload services: your file is copied to somebody else's computer, worked on there, and handed back. That is a real architecture with real advantages, and it has one enormous cost. Here is the comparison, with the cases where they win at the bottom.
| What matters | Pagecraft | An upload-based site |
|---|---|---|
| Where your file goes | Nowhere. It is read by this tab and never transmitted, so a contract or a medical record stays on the machine it was already on. | To their servers, where it is stored at least as long as the job takes, is readable by their staff and their subprocessors, and is subject to whatever their retention policy says this week. |
| How long it takes | The time the work takes, on your machine. No upload, no queue, no download — a 100MB file starts instantly, because it is already here. | Upload, wait in a queue behind everyone else, then download. On a slow connection, the transfer is most of the wait. |
| What it costs | Nothing, with no paid tier that unlocks anything. Every feature is in the free product, because running it costs us nothing. | Free up to a point: a few tasks a day, a file size cap, and a subscription for the rest. Somebody has to pay for the servers your file is sitting on. |
| What you have to accept | Nothing. No account, no email address, no consent dialog, no watermark on the result. | Usually an account, often a cookie banner and advertising, sometimes a watermark, and terms of service granting a licence to process the file you just handed over. |
| Needing a network | Only for the first visit. The site saves a copy of itself to your device as you read it, so after that it opens with the network unplugged and every tool works exactly as it did. Once it has loaded, no tool here makes a single request anyway, so pulling the plug mid-job changes nothing. | For everything. Without a connection there is no product at all, because the work happens somewhere else. |
| Whether you can check the claim | Yes, in about ten seconds: open the network panel, or disconnect. The source is public, so you can also read exactly what runs. | No. "Files deleted after one hour" is a promise about a computer you cannot see, and no amount of good intent makes it verifiable. |
Where uploading is the better answer
Running on your own device is not free of cost, and there are jobs it is the wrong tool for. If you are in one of these situations, use something else — we would rather say so here than have you discover it half way through.
- A very large document on a machine without the memory for it. The work happens in your browser, and a browser tab has a memory ceiling: a 1GB scan may simply fail here and will not fail on a server with 64GB.
- An old phone. Mobile browsers are given far less memory than desktop ones and reclaim tabs aggressively, so a job that takes a minute on a laptop can be killed part-way on a phone.
- Something we have not built. There are 48 tools here and that is not everything a PDF can need — if the thing you want is not on this site, a site that has it is more use to you than a principle.
- Work that has to happen without you. Anything on a schedule, triggered by an upload, or run over thousands of files in a pipeline needs a machine that is awake when you are not. The engine here is a package you can install and run on your own server for exactly that — which is not the same as sending your files to ours.
