PDF tools with no daily limit, and no upload
Online PDF tools generally ask you to upload your document to their servers, then cap how much you can do with it — the ones below all do. PDFCheetah does neither: merging, splitting, compressing, rotating, reordering and deleting PDF pages all happen in your browser, with no counter running. The reason is worth knowing before you trust either kind of tool with a document.
What PDFCheetah does
- No daily or hourly cap. There is no counter, because there is nothing to meter.
- Your file is never uploaded. Every tool runs in your browser, and an automated test fails the build if your document's bytes or its filename reach the network.
- No account, and no email address required to use anything.
- No watermark on anything you make.
- No size limits tied to a plan. What you can process depends on your device, and the tool shows the ceiling before you choose a file.

Why they meter and we do not
Online PDF tools that upload your file do the work on their servers, so each task costs them processing, storage and bandwidth. A cap is how they recover it. PDFCheetah does the work on your device, so the same task costs us nothing — there is no cap to sell you out of.
What a daily limit actually costs you
A cap costs you nothing until it costs you the thing you were in the middle of. You have a scanned contract to send in ten minutes. You split it, rotate the two pages that came out sideways, and go to take the blank sheet off the back — and that third job is the one refused until tomorrow. One task in your head. Three on somebody's counter.
Tomorrow is the wrong unit for document work. Documents are wanted at the printer, before a meeting starts, or by someone waiting on the file now. A limit that resets at midnight does not cost you a day; it lands on the ten minutes you had. The offer that appears next is not a coincidence, and not malice either: metering is how a tool that works on its own servers pays for them, and the moment you are blocked is the moment a plan is worth the most to you.
A quieter cost comes first. Once you know a counter is running you arrange your work around it — saving small fixes up so they go through together, or finishing on a second site because the first one is spent. To get around one company's limit, you have handed your document to two companies instead of one.
What runs in your browser, and what that changes
When you choose a file here, nothing is sent. The page reads it from your own disk, and the code that reads, draws and rewrites the PDF runs inside your browser, on a background thread so the page keeps answering you while it works. There is no queue and no counter, because a job on your own machine costs us the same whether you run one or forty.
That is not a claim to take on trust, so it is tested rather than promised. An automated check drives the real tools in a real browser and watches every request the page makes; the build fails if your document's bytes or its filename turn up in one. It matches literal bytes and a planted marker, so it is strong evidence rather than proof, and saying where the check stops is better than letting the word never do work it has not earned.
What does leave is the page's own files, and a short record of use: which tool you opened, roughly how you arrived at it, how many files you chose as a range rather than an exact number, what your browser is capable of, whether a job started, whether it succeeded or failed, roughly how long it took, whether you downloaded the result, and an error code if it broke. No cookie, and no identifier that outlives the tab. The privacy page lists the same set.
Running on your device cuts both ways, and this is the side that cuts against us. Your computer is the machine doing the work, so a large file is bounded by your own memory rather than by a plan you could buy, and there is no bigger server to fall back on. The tools weigh a file before they start and refuse in advance rather than failing halfway through, and the ceiling is lower on a phone than on a laptop. That limit is real. It is not one anybody can sell you out of.
A long job may also write working data to a private area on your device, because holding a long document in memory all at once is how a tab runs out of it. It is cleared up after the job, and if you want it gone sooner, every tool carries a control that deletes it.
Some things a browser cannot do well, so they are not offered. Six tools are finished — merge, split, compress, organize, rotate, and delete pages — and the rest of the list says it is not ready rather than doing the job badly. The same rule holds inside the tools that shipped: compressing will not touch a document locked with a password, and it offers you an option only when that option saves at least five percent. Merge warns you that form fields and signatures do not survive being combined.
How to check any PDF tool's limits before you trust it
None of that is worth much if you have to take our word for it. Here is the check we would run on any PDF tool before trusting a document to it, this one included.
Read the pricing page before the tool page
The tool page sells the tool; the pricing page is where free gets defined. Look for a count of jobs per day or per hour, a size limit for one file, a limit on files per job, and whether the free result comes back marked.
Find out where your file goes, and for how long
A tool that works on its own servers should say so plainly and say when your file is deleted. An hour is a good answer. Two weeks is an answer you can weigh. No answer at all is the one to walk away from.
Watch your own network traffic
Open your browser's developer tools, go to the network panel, then choose your file and run the job. You are reading the size of what goes out. Small requests for the site's own pages, code and usage records are normal; a tool that uploads your document shows a request as large as it is.
Turn the connection off and try again
A server cannot be reached from a plane, which makes this the strongest test. Load the site once with a connection, switch on airplane mode, reload, and run a real job. Here it has been measured end to end in Chrome on the rotate tool, and the other tools are saved by the same step; Safari and iPhone are unchecked, so treat those as unknown.
Then run the same check on us
Our pricing page has one free plan and no counter to describe, and our privacy page lists everything that leaves your browser in the same words as above. If any of it turns out not to be true, we would rather hear it from you.
A reader who runs this and then picks another tool has still come out ahead. Nobody should have to find out what a tool costs them at the moment they are least able to argue about it.
