About this editor

This is a free PDF editor that runs entirely in your browser. There's no upload step because there's no server to upload to: the editing engine is PDFium (the same library Chrome uses to render PDFs), compiled to WebAssembly and running in your tab. Open a file and you can edit the actual text on the page rather than only pasting boxes over it: click a line, retype it, and the replacement is written into the PDF with the document's own fonts.

Beyond text, the editor covers the everyday jobs in one place. Add text boxes, highlights, freehand drawing, and shapes. Sign by drawing or typing a signature and placing it anywhere. Fill out PDF forms and save a copy with the answers baked in, or flatten the form entirely. Reorder, rotate, duplicate, delete, and extract pages from the sidebar. Stamp a watermark across every page. Search inside the document, and undo anything: edits are only permanent when you save.

Saving is where most "free" editors spring their trap; this one doesn't. Exports carry no watermark, no daily quota, and no account. When you save, you can also shrink the file or add password protection (AES-256 encryption) in the same step, so an edit-compress-protect job that normally takes three websites finishes in one download.

The privacy claim is one you can check for yourself. Open your browser's developer tools, watch the Network panel, and edit away: your document never appears in a request, because the page's security policy prevents it from talking to anything but itself. Your file never reaches a server, so there is no server-side copy to delete. The editor does keep your recent files and unsaved work in this browser's on-device database, IndexedDB (so a closed tab or a crash doesn't lose your place), but that copy never leaves your device, and you can clear it anytime from the start screen.

Scanned PDFs work too. If a document looks scanned, the editor offers to run OCR on it, locally like everything else, so the pages gain a searchable, selectable text layer before you start working.

Frequently asked questions

Is this PDF editor really free?
Yes. Editing, signing, form filling, page organization, watermarking, and saving are free, with no watermark added, no daily limit, and no account required. The site plans to sell optional convenience passes for power features, but the editor itself stays free.
Is my PDF uploaded to a server?
No. The editor runs in your browser using WebAssembly, and the page's Content-Security-Policy prevents it from talking to anything except the site itself. More importantly, you don't have to take that on faith: open DevTools, watch the Network tab while you edit and save. Your document never appears in a request.
Can I edit the existing text, or only add annotations?
You can edit the existing text. The editor uses PDFium to replace text runs inside the PDF itself, matching the original fonts where they are embedded. You can also add new text boxes, highlights, drawings, and shapes on top.
Can I sign a PDF here?
Yes. Draw a signature or type one in a signature style, then place, resize, and move it on any page. Signatures are flattened into the saved PDF like ink on paper.
Does it work on scanned PDFs?
Yes. Scanned pages open normally for annotating and organizing, and the editor offers to run OCR, also locally in your browser, so the text becomes searchable and selectable. Text-replacement quality on scans depends on the document; the editor warns you up front.
Is there a file-size or page limit?
No fixed limits. Because nothing is uploaded, there's no upload cap: the practical ceiling is your device's memory, and ordinary laptops handle large documents including hundred-page scans.
Can I compress or password-protect the PDF when I save?
Yes. The Save button has an export-options panel: reduce the file size (three quality presets) and/or encrypt the output with a password (AES-256). Both run locally and apply to the edited document in one download.
