Edit PDF online
Add text, images, shapes or freehand annotations to a PDF. Free, secure, and works on any device — no signup required.
PDFWix's editor handles the 80% of PDF edits people actually need: add text on top of a form, drop in an image, draw a shape or arrow, highlight a passage, or scribble a freehand note. It's not Acrobat Pro — we don't reflow paragraphs or re-extract original fonts — but for filling forms, marking up reviews, or adding a logo to a page, it's faster and free. Everything happens in your browser; the PDF never reaches our server.

Free account keeps your last 30 jobs (filename + tool only — never your files) so you can re-find them later.

How to edit a PDF online
- 1
Upload your PDF
Click "Select PDF file" or drag the document into the upload box. The file stays in your browser — never uploaded to our server.
- 2
Add text, images, shapes or highlights
Pick a tool from the toolbar — text, image, rectangle, ellipse, line, arrow, highlight or freehand pen — and click on the page to add it.
- 3
Position and style each annotation
Drag annotations to reposition; use corner handles to resize. Tweak colour, font, line weight and opacity from the side panel. Hold Shift while dragging to constrain alignment.
- 4
Download the edited PDF
PDFWix flattens your edits into the downloaded PDF so they appear identically in every reader. Keep a copy of the original if you might want to re-edit.
Tips for editing PDFs
Existing text isn't editable line-by-line
PDFs aren't like Word. To fully edit body text, convert to Word first, edit, then re-export.
Use shapes for redaction-by-cover-up
A black rectangle hides text visually but the underlying text is still searchable. For real removal use Redact PDF.
Snap to alignment
Hold Shift while dragging an annotation to constrain to vertical/horizontal. Saves a lot of fiddling on forms.
Highlight is your friend in reviews
Highlight + a freehand circle around a problem area communicates faster than long comments.
Save versions
Edits flatten on download. Keep a copy of the original before saving so you can re-edit later if needed.

Why use PDFWix to edit PDFs?
-
Add text on top of any page. Type directly onto the PDF — perfect for filling forms, adding labels, or correcting a typo on a finished document.
-
Drop in images. Insert logos, signature graphics, or diagrams. Resize and reposition with drag handles.
-
Shapes and arrows. Rectangles, circles, lines, and arrows for marking up reviews, redlining drafts, or pointing at issues.
-
Highlights and freehand. Highlight passages in five colours and scribble freehand notes — feels like marking up paper.
-
Browser-side editing. All edits happen locally. The PDF never reaches our server, so confidential markup stays confidential.
-
Free, no signup, no watermark. Most online PDF editors hide downloads behind a trial. PDFWix doesn't — edit and download as many times as you want.

Frequently asked questions
Can I edit existing text in the PDF?
PDFWix lets you cover text and type new text on top, which works for short fixes. For full paragraph editing, convert to Word first, edit there, then re-export to PDF.
Will the original file be modified?
No. PDFWix always produces a new PDF. Your source file stays untouched on your device.
Are edits saved into the PDF or just the viewer?
Edits are flattened into the downloaded PDF, so they appear identically in every reader, on print, and after re-saves.
Can I undo edits later?
Edits flatten on download. Keep a copy of the original if you might want to re-edit. Within a single session you can undo with Ctrl/Cmd+Z.
Will my file be uploaded?
No. PDFWix's editor runs entirely in your browser — the PDF never leaves your device during editing.
Is there a page limit?
No. The editor handles single-page forms or 500-page reports — performance scales with your device's RAM.
