PDF Editor

Click any line of text and retype it — the change is written into the PDF itself, so it keeps the document's own font, size and position, or pick a new size, colour, bold or italic from the style bar. A replacement that's noticeably wider than the original is shrunk to fit rather than left overlapping. You can also add fillable text fields and checkboxes, add text, draw freehand, add shapes, insert images, sign, redact text so it is genuinely removed, rotate, delete or drag-reorder pages, and OCR a scanned PDF to make it editable. Full undo and redo, and nothing leaves your browser.

Processed entirely in your browser — your files are never uploaded to a server.
Most edits are rewritten directly inside the PDF, keeping the original font exactly. Where that isn't possible the text is repainted instead — the tool tells you when that happened, because in that case the original string stays recoverable inside the file. Editing does not reflow surrounding text, and scanned PDFs have no text layer to edit.
