How to Edit a PDF Online for Free

What can you edit in a PDF?

PDFs are designed to preserve layout and formatting across devices, which makes them trickier to edit than Word documents. However, most of what people actually need — rearranging pages, fixing orientation, removing pages, adding notes — can be done without touching the original text content at all.

PDF Genie Online supports the following editing operations:

• Reorder pages — drag pages into any sequence you need
• Rotate pages — fix landscape/portrait orientation issues
• Delete pages — remove blank pages, duplicates, or irrelevant sections
• Add text annotations — overlay typed text on any page
• Draw freehand — sketch, sign, or highlight with a pen tool
• Stamp images — place a PNG or JPG (such as a signature) on any page
• Merge files — combine pages from multiple PDFs into one

Step 1 — Upload your PDF

Go to the PDF Genie Online home page and drag your PDF file onto the upload zone, or click the zone to browse and select a file. You can upload multiple PDFs at once if you want to merge them.

A progress bar appears while the file loads into your browser's memory. For a typical PDF this takes one to three seconds. Nothing is sent to any server — all processing is local.

Step 2 — Reorder pages

Once your PDF opens in the editor, you see a grid of page thumbnails. Each thumbnail shows a preview of that page.

To change the order of pages, simply click and drag a thumbnail to a new position in the grid. A highlight indicates where the page will land when you release. The order of the thumbnails is the order the pages will appear in your final downloaded PDF.

This is especially useful when:

• A scanner saved pages out of order
• You have merged multiple PDFs and need to interleave their pages
• You want to move an appendix to the front

Step 3 — Rotate pages

Each page thumbnail has a small rotate button (a curved arrow icon). Click it to rotate that page 90° clockwise. Click it again to rotate another 90°, and so on. A full 360° rotation returns the page to its original orientation.

Rotation is applied permanently when you download — there is no separate "save" step. The rotation you see in the thumbnail is exactly what will appear in the downloaded file.

Step 4 — Delete pages

To remove pages from your PDF, click the checkbox that appears in the corner of each thumbnail when you hover over it. Select all the pages you want to delete, then click the Delete selected button that appears in the editor toolbar.

You can select multiple pages at once. This is useful for:

• Removing blank pages left by a scanner
• Stripping cover sheets or confidential pages before sharing
• Extracting a subset of pages from a large document

Step 5 — Download your edited PDF

When you are satisfied with your edits, click the Download button in the toolbar. The browser assembles the final PDF — applying all your reordering, rotations, deletions, and annotations — and saves it to your device.

The downloaded file is a standard PDF that opens in any PDF reader: Adobe Acrobat, Preview on Mac, Chrome's built-in PDF viewer, or any other software. All edits are permanently embedded in the file.

Is online PDF editing safe?

The biggest concern with online PDF tools is privacy — you may be uploading sensitive contracts, financial documents, or personal records to someone else's server. With PDF Genie Online, that concern does not apply.

All editing takes place inside your browser using WebAssembly and JavaScript libraries. Your files are loaded into browser memory and processed there. They are never sent over the network. When you close the tab, all data is automatically deleted from browser storage. There is no server receiving your documents.
