How to Write on a PDF Online: A Step-by-Step Guide

Follow these simple steps to start editing your documents immediately:

  1. Upload your file: Visit our /tools/editor page and drag your PDF into the upload area.
  2. Select the text tool: Choose the 'Text' option from the toolbar.
  3. Click and type: Place your cursor anywhere on the page and start typing. You can change font sizes, colors, and styles to match the original document.
  4. Save and download: Once you are satisfied with your edits, click the 'Export' button to download your new file.

Beyond Typing: Manage Your Documents Efficiently

Writing on a PDF is just the beginning. CrazyDocument offers a full suite of tools to handle your document workflow. If you have multiple files that need consolidation, use our /tools/merge tool. If your file is too large for an email attachment, try our /tools/compress utility.

For users dealing with scanned documents that aren't selectable, our /tools/ocr tool can turn images into editable text, making it much easier to write on a PDF that was previously just an image.

Frequently Asked Questions

Can I change the font style when I write on a PDF?
