Typical workflow

  1. 01

    Choose the conversion

    Merge PDF combines PDFs, photos, and Word or PowerPoint files into one PDF. Compress and Optimize PDF shrinks one PDF. One Photo to Document converts a single photo. Many Photos, One PDF puts several photos into one PDF. PDF to Office extracts a PDF into Office files. Word Counter measures a draft.

  2. 02

    Provide the source

    Upload the images or PDF, or paste the text. Turn on OCR when the source is a scan and the tool offers it.

  3. 03

    Pick the output

    Choose the target format, page options, or counting rules such as whether spaces count as characters.

  4. 04

    Check the result

    Download the file or read the counts. Skim OCR output before you send it, because scans can misread characters.

Best practices

  • Use a straight, high-contrast scan when you enable OCR.
  • Word Counter updates as you type. Download the draft if you want a copy outside the page.
  • PDF to Office follows the structure of the PDF. Complex layouts may need a quick edit in the Office file.

Privacy & limits

Document tools send the file or text to the DevStack API and return the conversion or counts. Do not upload documents you are not allowed to share with the service.

Frequently asked questions

Does OCR run automatically?
