User Guide

Edit directly on the document.

Select file → Enter text → Place signature → Organize pages → Check results. Files are processed within the browser.

Open file

Select PDF, PNG, JPEG or drag and drop them into the file selection area. Multiple files will be combined in order. Use the 'Add File' button at the top while editing. There is no fixed guarantee limit for size and number of pages, and it depends on the device's memory and document complexity.

Enter text on the document

  1. Select 'Text' and click the desired location in the document.
  2. Enter text and change the size, alignment, and color from the toolbar near the element.
  3. Finish input by clicking the Done button or Escape. Double-click the text to edit it again.

Empty boxes will be removed when input is finished. Existing PDF content cannot be modified. Precise positioning, line spacing, and local font loading can be used in 'Details'.

Signature, Seal, and Check Placement

Draw directly or import an image in 'Signature.' In 'Stamp,' you can select PNG/JPEG to organize a solid color background. After using the result, click on the desired location in the document. With the keyboard, focus on the page and press Enter to place it in the center.

Drag the body of the selected element to move it and use the corner handles to resize it. Clicking on an empty document or a gray area will deselect it. Place the check by pressing 'Check' and then putting it in the desired position.

Page organization and extraction

In 'Edit', you scroll through the document continuously. 'Page List' allows you to collapse or expand thumbnails. In 'Organize Pages', you can change the order by dragging the page grid or using the move buttons, and rotate, delete, or extract selected pages. The delete button on individual cards deletes only that page.

Extracting pages does not change the current document. Download a separate PDF from the result window. Adjust the paper, alignment, and margins of the image in the 'Page Setup' on the edit screen.

Edit with keyboard

  • Delete / Backspace: Delete the selected element. While typing, only characters are deleted.
  • Arrow keys: Move 1pt in the screen direction. Hold Shift to move 10pt.
  • Ctrl / Cmd + Z: Undo. Press Shift together to redo.
  • Escape: End input, cancel batch, or deselect.
  • In the page arrangement handle, Space: grab/release. Arrow keys: reorder.

Check results and download

'Check Results' creates a new PDF with the original and the current edited state and reopens that file for you to view. After confirming the number of pages, file name, warnings, and content, please download it. If the result of your work has changed, it will be marked as 'Not Latest,' so you need to regenerate it. After requesting a download, check whether it is actually saved in the browser's download list.

Support limit

Encrypted PDF, digitally signed PDF, and corrupted files cannot be edited. Forms, comments, links, bookmarks, and attachments may not be preserved. Keep the original and check the results. OCR, editing the existing content, certificate-based digital signatures, and cloud storage are not provided.

Korean, Latin characters, and numbers are supported with the default font. Complex script typesetting such as Arabic, Hindi, and Thai is currently not supported, and export is blocked. If necessary, please select a supported local font. Playwright WebKit Test and actual Safari device validation are different, and the actual Safari device is pending separate verification.

Refresh and Local Library

The current document and work exist only in memory, so they will disappear if you refresh or close the tab. The project is not automatically saved or recovered. Signatures and stamps are saved in this browser's storage only if the user chooses to save them. Even if the storage is blocked, you can continue editing the current document.
