The short answer
For the everyday jobs — merge, split, compress, convert, OCR a scan, fill and sign a form — a browser tool does them free and there is no reason to pay a subscription. For prepress, PDF standards work, advanced redaction and offline desktop workflows, a professional desktop application is still the right tool and we will not pretend otherwise.
| What you need | PDFZivo |
|---|---|
| Use it without creating an account | Yes for the everyday tools and OCR — guests can run them. AI tools are the exception: they need a signed-in account. |
| Install software | Nothing to install. Every tool runs in the browser, on a phone the same as a laptop. |
| Know what happens to the file afterwards | There is no general cloud storage. Uploaded and processed files are temporary and deleted automatically. |
| A free tier that is actually usable | Free with fair daily limits rather than a trial that expires. Paid plans raise the limits. |
| OCR on scans and photos of documents | Free for everyone, including guests, within per-plan limits. |
| Hit an exact file size, not just "smaller" | Compression takes a target size in KB and reports honestly whether it reached it. |
| Process several files in one go | Batch processing is available on the plans that include it, with the results returned as a single zip. |
| AI help with the document, not just the file | AI tools are metered in AI Credit: 50 per month on a signed-in free account, 0 for guests, more on paid plans. |

Two different questions behind the same search
The first version is the common one: someone needs to sign a form, shrink a file, merge a few pages or make a scan searchable, and does not want a professional subscription for it. That is a browser-tool job and always has been.
The second version is a professional replacing a desktop application inside a real production workflow. That is a different conversation, and anyone who tells you a free web tool covers it fully is selling something. The two questions get confused because they use the same words, so it is worth deciding which one is yours before comparing anything.
The everyday jobs, covered
Merging, splitting, reordering, rotating, compressing, protecting and unlocking, plus conversion between PDF and Word, Excel, PowerPoint and images, all run in the browser with nothing installed and no account.
Filling and signing sit here too: you can complete a PDF form and add a signature without a desktop application. And for scans, OCR is free for everyone including guests within per-plan limits — which is the specific capability people most often assume requires a paid product, because for a long time it did.
Where a desktop application still wins
This is the honest part. A professional desktop suite is not just a bigger set of the same buttons — it is a different category of software, and several of its strengths cannot be reproduced in a browser tab.
Offline work is the obvious one: no browser tool functions on a plane or an air-gapped machine. Beyond that, prepress and print production, PDF standards compliance and preflight, colour management, deep accessibility tagging, certified digital signatures, advanced redaction with verifiable removal, and managed enterprise deployment with a support contract are all reasons organisations buy the desktop product and keep buying it. If your work depends on any of them, a free web tool is not an alternative — it is a different thing that happens to open the same file format.
What it costs, and what happens to your files
The free tier is free with fair daily limits rather than a trial. Paid plans raise limits, add batch processing and allow larger uploads. AI document tools are metered in AI Credit — 50 a month on a signed-in free account, none for guests, more on paid plans.
On files: there is no general cloud storage. Uploads and results are temporary and deleted automatically. For a document you are simply passing through a tool, that is the desirable behaviour; if you need a synced library of your documents, you need a different category of product.
How to decide in one question
Ask what you did with a PDF in the last month. If the honest answer is signing, merging, compressing, converting or reading a scan, a browser tool covers it and a subscription is money spent on capability you are not using.
If the answer involves print production, compliance standards, redaction that must be provably complete, or working offline, keep the desktop application. Those are not gaps a free tool is quietly close to filling.
No general cloud storage — uploaded and processed files are temporary and deleted automatically.
