Start with the right kind of PDF
Open the editor and choose your PDF. A document with embedded text usually shows outlined lines in Select or Edit text mode. If the page is a scan or photograph, there may be no text to select. In that case, use Cover over the old words, then Add text. Paperkit does not perform OCR.
Select the line you want to change
Click an outlined line in Select or Edit text mode. On a computer, type directly on the page. For example, replace “Meeting: Monday” with “Meeting: Tuesday” in a simple notice. Paperkit covers the original line visually and places your replacement above it; it does not rewrite the original PDF's text instructions.
Fit the new words to the space
Choose a font close to the original, then adjust its size and color. Drag a side handle to change the box width or a top or bottom handle to change its height. Text wraps to the width. Use Fit text or make the box taller if the editor warns that some text is hidden. Drag the Move grip to reposition the box.
Understand Remove and Restore original
Remove on replacement text removes your new words while leaving the original area covered. Restore original discards the replacement and reveals the original content. These are different actions. Use Undo immediately if you choose the wrong one; changes can be reviewed before downloading.
Inspect the exported copy
Choose Download PDF, review the quality option, and save a new file. Open that file and check line breaks, masks, punctuation, and alignment. Edited pages are flattened into images: text selection, links, and interactive fields are lost on those pages. Digital signatures are not preserved. Keep your original document.
