What is the best free PDF editor online that stays private?

LovePDF’s PDF Editor runs entirely in your browser with live preview. You can reorder pages, add text, watermarks, signatures, page numbers, and crop without uploading the file.

Does the PDF editor upload my file?

No. Editing happens locally on your device. Closing the tab clears the in-memory document.

Can I see a live preview while editing?

Yes. The selected page renders in a large live preview. After you apply an edit, the preview refreshes so you can confirm the result.

How do I place text or a signature exactly where I want?

Open the Text, Watermark, or Sign tab, click the live preview to set a placement marker, then press Apply.

Can I reorder and delete PDF pages?

Yes. Use the Pages tab and filmstrip to drag pages, rotate them, or delete extras, then apply the page layout.

Is this a full Adobe Acrobat replacement?

It covers the most common edit tasks privately in the browser. It does not include certificate digital signatures, OCR, or complex form design.

Can I add page numbers and crop margins?

Yes. Use the Numbers and Crop tabs, apply the change, and check the live preview before downloading.

Does the free PDF editor work on mobile?

Yes. The workspace is responsive. For precise click placement, a larger screen is more comfortable.

What file size can I edit?

LovePDF accepts PDFs up to 100 MB. Very large page counts preview a capped set of pages for performance.

How is the PDF Editor different from Sign PDF or Watermark alone?

Those tools do one job. The PDF Editor combines page organization and multiple overlays in one live-preview workspace.

How it works

The PDF Editor loads your file into memory and renders pages with PDF.js for the live preview and filmstrip. Edits are applied with pdf-lib: page rearrange/rotate/delete, text and image overlays, signatures, page numbers, and crop boxes. Each Apply updates the working PDF and refreshes the preview so you can stack edits safely before downloading.

Why choose LovePDF.online

Most “online PDF editors” upload your file to a remote server. LovePDF keeps processing local while still delivering a powerful workspace: live preview, page organization, stamps, signatures, numbering, and crop. It is the flagship edit experience on LovePDF.online — free, private, and built for real documents.

Privacy and security

Your PDF never leaves your device. Previews, overlays, and exports run in the browser with pdf-lib and PDF.js. LovePDF does not store your documents on a server.
