What is Draftable?

Draftable is a tool that helps you to compare any two documents online. It highlights (redlines) all differences between the two files so that you can find changes quickly. Click here to see a sample comparison.

What Types of Documents Can I Compare?

Using our online text diff checker software, you can compare any two PDF Files, Word Documents, Excel Spreadsheets and PowerPoint Files. That's right - you can compare a PDF file with a Word Document, side-by-side! Draftable will redline all deletions and highlight all new changes.

What is Redline Document Comparison?

Often referred to as legal blackline or redline, document comparison enables you to quickly check for all changes instead of manually finding them yourself. Draftable highlights all the changes in our side-by-side viewer, redlining deletions and highlighting all new additions.

Useful Information

New to Draftable?

Starting a comparison

Using our free online compare tool is simple:

  1. Upload an older/base file with the left button.
  2. Upload a newer/target file with the right button.
  3. Hit Compare.

Differences in documents are highlighted

When your comparison is complete, you will see two documents side-by-side, with the changes highlighted.

  • Deleted text (on the left but not the right) is highlighted red.
  • Inserted text (on the right but not the left) is highlighted blue.
  • Text that has been replaced is considered a combination of deleted text and inserted text.

Sync Scrolling

You'll notice that your documents will scroll together, sometimes at varying speeds. This is Sync Scrolling optimising your text comparison viewing experience. You can disable this by toggling the button.


Something is highlighted but hasn't changed

Inevitably, there are times when Draftable isn't certain about a change. In these cases, we highlight them to ensure no change is missed.

My whole document is highlighted (or un-highlighted)

This typically means that your document has been scanned, and is actually just an image. Running your document through Optical Character Recognition (OCR) software, which converts documents into machine-encoded text, will generate a text layer with differences that Draftable can read. This is especially useful for comparing and analysing comparative texts. We recommend using Adobe Acrobat or PDF-XChange for optimal results.

My document is too long or too large

The file size limits for our online compare tool are 300 pages and 10 MB.
To compare larger documents (or Excel spreadsheets content), try Draftable Desktop.
