▚ files open locally — nothing is uploaded
- 01Open a PDF. Pages render locally in your browser — nothing is uploaded.
- 02Pick a tool from the toolbar: Text, Image, Highlight, Whiteout, Box or Draw, and click the page to place it. Drag to move, use the corner handle to resize.
- 03Switch pages to edit them too, then click Save — your browser bakes all edits into a new PDF and downloads it.
The documents people edit are the ones that matter: a contract that needs one correction before signing, a form with no interactive fields, a report that needs a stamp or a note. Online editors usually ask you to upload that document first — which is a strange demand for the most sensitive file on your desk.
ZorPDF's editor keeps the whole session on your device. Page previews are rendered by your browser's own PDF engine, your edits exist only in the tab's memory, and saving rebuilds the file locally. Fill a form with the Text tool, cover an old value with Whiteout and type the new one over it, highlight a clause, drop in a logo, or mark up a draft with the pen — then save and you're done. No account, no watermark, no copy of your contract on someone else's server.
What can I add to a PDF with this editor?+
Text (any size and color), images (JPG or PNG — logos, stamps, photos), yellow highlights, whiteout blocks to cover content, outlined boxes, and freehand pen drawings. Elements can be placed on any page, moved, resized and deleted before you save.
Can I edit the text that's already in the PDF?+
Yes — switch to 'Edit text' mode and every line of text becomes clickable. Click a line and it's replaced with an editable copy in the same position, size and color, set in the closest standard font (PDFs embed locked font subsets, so an exact font match isn't possible — that's true of every editor). Scanned documents are pictures of text with no text layer, so they can't be click-edited; use whiteout plus new text there instead.
Does editing a line really remove the original text?+
Visually yes — the original is covered and your version is shown. Technically the old text still exists underneath in the file and could be extracted, so for redacting genuinely sensitive content (names, account numbers), don't rely on any visual editor — including this one. True redaction requires rewriting the document's content streams.
Is my document uploaded while I edit?+
No. The page previews are rendered by your own browser, your edits live in your browser tab's memory, and the final PDF is assembled on your device. Nothing about the document — content, file name, or edits — is transmitted anywhere.
How do I fill out a PDF form that has no interactive fields?+
Use the Text tool: click where an answer should go, type it, and adjust the size so it fits the line. This works on any form, including scans — which is what most 'fill and sign' tasks really are.
Can I sign a document with this editor?+
You can place a signature image with the Image tool, but the dedicated Sign PDF tool is more comfortable: draw your signature once, then click to place it — with automatic background removal.
