PDF power tools
Choose the job you need, preview the change, and download a real result. Processing stays in your browser, with destructive trade-offs stated before they run.
Local by design
PDF bytes and passwords remain inside the active browser session.
No account gate
Open a tool, process the file, and download the result without registration.
Built for real PDFs
Mixed page sizes, rotations, annotations, and encrypted documents receive explicit handling.
Each tool does one job well. Pick the workflow that matches what you need to change — or open the full editor when you need to fill, sign, or mark up a document rather than reshape its pages.
No. Every tool is completely free with no sign-up, watermarks, or export limits. Open a tool, process your file, and download the result.
No. All processing runs inside your browser tab using your own device — the PDF, and any password you enter, never leave your computer.
The twelve tools are single-purpose workspaces grouped by the job they solve. The editor is for filling forms, signing, highlighting, erasing, and chaining compatible document operations. They share the same local processing pipeline.
Yes. When a tool needs to modify a protected file it asks for that file's password, and the Unlock tool removes protection from a document you are authorized to open. Passwords are used locally and never transmitted.
Most PDF problems are one of a handful of jobs wearing different clothes. If one of these sounds like your afternoon, the walkthrough is the whole solution — not a teaser.
An application wants a single PDF: the form, two pieces of ID, a letter, and a pay stub. Put them in the order the checklist asks for, merge, then add page numbers so the reviewer can cite a page. If one of the six is a photo rather than a PDF, print it to PDF first — every browser and phone can do that from the share sheet.

Split accepts ranges the way you would write them by hand — 4-9, or 1-3,7,12-14 — and gives you either one PDF containing those pages or each range as its own file inside a ZIP. Use one PDF when you are forwarding an excerpt, and the ZIP when different pages go to different people.
Rotate handles orientation — all pages, only odd or even, a range, or individual pages you click — and it is lossless, so nothing is re-rendered. Organize is the drag-and-drop view for reordering, duplicating, and deleting pages. Do rotation first: it is easier to judge order once every page is the right way up.

Protect applies AES-256 encryption with an open password (needed to view) and an optional owner password (needed to change permissions). Set them to different values — an open password that also unlocks every permission is not protecting much. Send the password through a different channel than the file.
Unlock takes the password you already have and writes out a copy without it, then verifies the result reopens with no credentials before the download starts. It is for documents you own or are authorized to access — a statement from your own bank, a file your employer sent you. It does not recover or guess a password you do not have.
That is the editor rather than a tool. It fills form fields, places text and checkmarks anywhere on a page, takes a drawn signature, highlights, and covers text with white-out — and it has all ten tools built in, so you can merge or rotate mid-edit without losing the fields you have already filled.
“Nothing is uploaded” is a claim worth spelling out. When you choose a file, the browser hands this page a reference to it on your disk — the same mechanism that lets you attach a file to an email without the page reading your whole drive. The bytes are read into memory in this tab. Nothing is sent anywhere, because there is no endpoint on our side that accepts a document.
The work itself runs in a Web Worker: a second thread inside the same tab. That is why a 300-page merge does not freeze the interface and why the progress messages update while it runs. The worker builds a brand-new PDF, hands the finished bytes back, and the download you get is generated on your own machine.
When you close the tab, all of it is gone. There is no history to clear, no account holding a copy, and nothing for us to hand over if someone asks — we never had it. The practical consequence is worth knowing: nothing can be recovered after the fact, so save the result before you close the tab.
