The short answer
For one-off PDF and image jobs — merge, split, compress to a size, convert, OCR a scan — PDFZivo runs them in the browser, free, without an account, and deletes the file afterwards. For bulk work, check the batch limits on both sides against the number of files you actually process in a week.
| 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. |

Compare the task, not the feature list
Every online PDF suite has roughly the same top-level list: merge, split, compress, convert, rotate, protect. Comparing those lists tells you almost nothing, because the difference is never whether a tool exists — it is what happens at the edges.
The edges are where work actually stalls: the file is a scan rather than a real PDF, the upload form has a hard size cap, there are eighteen files rather than two, or you are on a phone with no patience for an install. Judge on those, and the comparison gets much shorter.
The everyday jobs, and how they work here
Merging, splitting, reordering, rotating, protecting and unlocking, plus conversion between PDF and Word, Excel, PowerPoint and images, all run in the browser without an account.
Two cases deserve specifics. Compression accepts a target size in KB rather than a vague "maximum" setting, and reports truthfully whether it reached it — the difference between a file that clears an upload limit and one that nearly does. And OCR, which turns a scanned page into searchable text, is free for everyone including guests within per-plan limits, so a photographed document does not become a dead end.
Doing more than one file at a time
Bulk is the honest weak point of every free tier, ours included, so it is worth being precise. Batch processing — running one tool across many files and getting a single zip back — is available on the plans that include it, not on the free tier.
If you process files in twenties every week, that is the number to compare between any two products, and it is the one that should decide your choice. If you process a handful a month, it will never matter and you can ignore this section entirely.
What it costs, and what happens to your files
The free tier has fair daily limits rather than an expiry date. Paid plans raise those limits, add batch processing and allow larger uploads. AI tools are metered separately in AI Credit: 50 a month on a signed-in free account, none for guests, more on paid plans.
On privacy the rule is short: there is no general cloud storage here. Uploads and results are temporary and deleted automatically. Nothing accumulates in an account, which is the point for a tool you reach for once and leave.
When switching is not worth it
If your current tool does the job, is paid for, and is already in everyone's bookmarks, switching costs more than it saves. Habit is a real cost.
Desktop and mobile apps, offline access, and integrations with the rest of your stack are also genuine reasons to stay. A browser tool that deletes your file afterwards is not trying to be a synced document library, and pretending otherwise would not help you decide.
A five-minute evaluation
Take the file that made you search, run the exact task, and see whether the result clears whatever gate it needs to clear — the upload form, the printer, the person who asked for it.
No install, no account for the everyday tools, and the file is deleted either way, so a failed test costs nothing but the minute.
No general cloud storage — uploaded and processed files are temporary and deleted automatically.
