How to use

Edit PDF objects, then inspect the exported copy

This editor can replace a supported text line or manipulate supported objects without converting the entire document to a screenshot. It is not a word processor: paragraphs do not reflow, scanned text is not editable, and a drawn signature is not certificate signing.

Step by step

  1. Open a PDF or Try an example. Inspect the page you need to change before selecting an object.
  2. Choose Text, Image, Highlight, Draw, Sign, Forms or Pages for the task. Apply the edit and review its placement at a useful zoom.
  3. Export PDF, reopen it in another viewer and check changed pages, searchable text, page order and form behavior.

Choosing the settings

OptionWhat changes
Replace text / add textReplacement changes a supported existing line; adding text creates a new object. A white shape over words is not a substitute for removing sensitive content.
Noto Sans / Noto Sans SCUse supported characters covered by the selected font. Font appearance can change; complex scripts and paragraph reflow are unsupported.
Forms / SignForms creates or fills supported fields; values support Latin text. Sign adds a visible handwritten mark, not a digital certificate signature.

Example and expected result

Try the built-in example and replace “Replace this sentence” with “Ready to share”. Make this one text edit, export and reopen the copy. Expected: the replacement appears, the old sentence is removed from that edited line, and the unchanged line remains searchable. Verify search and selection in the exported PDF rather than relying only on the canvas.

If it is not working

  • Input is limited to 20 MB and 200 pages; a session supports up to 100 edits and exports up to 60 MB. Added images are limited to 5 MB and 12 million pixels.
  • Encrypted, digitally signed and XFA documents are rejected. For scanned text, use OCR to extract it separately; this does not make the original scan's words editable here.
  • Cancel abandons an unfinished operation and keeps earlier edits. Changes stay in page memory until export. Download before leaving, and keep the original.

What can I edit?

Select ordinary PDF text or images, replace a text line using Noto Sans or Noto Sans SC, move or resize objects, add images, highlight, draw or add a handwritten signature. Use Pages to rotate, reorder or delete pages. Forms creates text fields, checkboxes and dropdowns and fills supported existing fields.

Fonts and documents

Text editing supports Latin, Greek, Cyrillic, Chinese and Japanese characters covered by the selected font. Font style may change. Complex scripts, paragraph reflow, scanned text, nested objects and certificate signing are not supported. Form values support Latin text. Encrypted, digitally signed and XFA documents are rejected. A drawn signature is only a visible mark.

Cancel and export

Cancel discards the unfinished operation and keeps earlier edits. Retry or export a copy before leaving. Files are never uploaded or stored. The first use downloads the local engine; Chinese editing also downloads a font. Reopen the exported PDF and check every changed page before sharing.
