Edit PDF Files Online for Free
Need to add text to a PDF, drop in a signature, or insert an image? Our free online PDF editor lets you place text and image overlays directly in your browser — no software to install, no account to create, and your files never leave your device.
Each page keeps a separate, finite history of up to 40 editing steps. Your exported PDF preserves the original text layer, so existing searchable text remains searchable.
What You Can Do
- Add searchable text — insert notes, labels, or corrections without flattening the original text layer.
- Insert images and logos — add stamps, signatures, logos, or photos and resize them freely.
- Per-page editing — each page has its own canvas and up to 40 history steps for undo and redo.
- Export with confidence — if your original PDF was searchable, the edited version stays searchable too.
How to Edit a PDF in 4 Steps
- Upload your PDF — drag and drop or use the file picker.
- Edit visually — click "Add text" or "Add image," move items where you need them, and adjust colors, sizes, and positions.
- Navigate pages — switch between pages; each keeps its own change history.
- Export — the tool merges your overlays with the original PDF structure so selectable text stays intact.
