About the Edit PDF tool
100% private: This tool runs entirely inside your web browser. Your files are never uploaded to a server — they never leave your device. That makes it faster, and it means your documents stay completely confidential.
What you can do
Open any PDF and edit detected text lines, run OCR on scanned pages, delete text, add new text boxes, insert images, draw freehand, add rectangles and highlights, and place content anywhere on the page. Desktop users get a thumbnail sidebar, zoom controls, and undo/redo; mobile users get the same editing tools in a touch-friendly layout.
How text editing works
Tallywise detects the PDF text layer, lets you edit those lines visually, masks the original text area, and writes your replacement text into the exported PDF. If a page is image-only, use the OCR button to detect readable text first, then click a detected line to replace or delete it.
