PDF Workbench
See every page of a PDF and rearrange it: merge, reorder, rotate, delete and extract pages, add watermarks or page numbers, edit metadata, and export pages as images or text. Nothing is ever uploaded.
How to Use
- Drop one or more PDFs in. Drop several and they are combined into one working document, in the order you added them.
- Every page appears as a thumbnail. Click pages to select them — shift-click for a range, or use Select all.
- Use the toolbar to rotate, delete, move or extract the pages you selected. Nothing is saved until you export, so experiment freely.
- Extras adds a watermark or page numbers across the document, and lets you edit the title, author and other metadata.
- Export the finished PDF, just the selected pages, the pages as PNG or JPG images, or the text content as a .txt file.
- Everything runs in your browser. The file never leaves your device, which matters when the document is a contract, a medical form or schoolwork.
What it does
About the PDF Workbench
Most online PDF editors have the same problem: before you can move a page, you have to hand the document to someone else’s server. That is an awkward trade for a signed contract, a medical form, a tax return or a child’s school report. This one does the whole job inside your browser tab — the file is read, rearranged and written back out on your own machine, and nothing is transmitted at any point. You can disconnect from the internet after the page loads and it still works.
How it works
Drop in one PDF or several — multiple files are combined into a single working document. Every page is rendered as a thumbnail so you can see what you are doing, and you select pages by clicking them, then rotate, delete, move or extract. Watermarks, page numbers and metadata apply across the document. Nothing is committed until you export, so you can experiment freely and simply reload if you change your mind. Exports include the finished PDF, just the pages you selected, the pages as PNG or JPG images, or the document’s text as a plain .txt file.

Frequently Asked Questions
Is my PDF uploaded anywhere?
No. The document is opened, edited and saved entirely inside your browser tab using pdf-lib and Mozilla's pdf.js. Nothing is transmitted, nothing is stored on a server, and the page keeps working with your network disconnected once it has loaded. That is the whole reason this tool exists — nearly every other online PDF editor requires you to upload the file first, which is a genuine problem for contracts, medical paperwork, tax documents and student records.
How big a PDF can it handle?
There is no fixed limit, but everything is held in memory, so very large documents are bounded by your device's RAM rather than by any quota. A few hundred pages is comfortable on a normal laptop. Thumbnails are rendered one page at a time and kept small on purpose so that a long document stays responsive.
Can it edit the actual text in a page?
No, and that is a deliberate boundary rather than an oversight. This tool works at the page level — reordering, rotating, deleting, merging, stamping. Rewriting words inside an existing page means reconstructing the original text layout, fonts and encodings, and tools that claim to do it usually either rasterise the page or quietly break the formatting. You can extract the text to read or reuse it.
What about password-protected PDFs?
Files that merely restrict editing usually open fine, because the tool ignores those permission flags. A PDF that requires a password to open at all cannot be read without that password, and this tool does not attempt to break encryption.
Why do the page thumbnails look slightly different from my PDF viewer?
Pages are rendered with pdf.js using its print pipeline, which is why form fields and annotations appear in their printable form. It also renders reliably when the tab is in the background, so a long export does not stall the moment you switch tabs.
Does it make the file smaller?
Saving rewrites the document structure, which often trims a little size, but this is not a compressor — it will not downsample your images. The most effective way to shrink a heavy PDF here is to delete pages you do not need, since embedded images are what usually dominate the file size.
Common Use Cases
Fix a scan that came out sideways
Rotate just the pages that are wrong, rather than the whole document, and save.
Combine paperwork into one file
Drop several PDFs in, drag the order right, and export a single document ready to send.
Pull out the pages that matter
Select a handful of pages from a long report and export just those as a new PDF.
Stamp a draft before sharing
Add a DRAFT or CONFIDENTIAL watermark and page numbers across every page in one pass.
Handle sensitive documents safely
Edit contracts, medical forms or student records without them ever leaving your computer.
Get the text out
Extract the readable text of a document to quote, search or reuse elsewhere.
