How To Adjust Line Spacing in PDFs

PDFs are designed to look the same everywhere, but that consistency can make edits tricky—especially if you need to set text to single spacing. 

With Smallpdf, you can quickly convert your PDF to Word, adjust the line spacing to single, and save it back as a polished PDF.

Start here: Use the converter below to upload your PDF and convert it to Word so you can adjust line spacing and save it back as a PDF.

Of course, saving your changes only updates the Word document. To convert it back to PDF format, you can choose the “Save a Copy...” option in Word and change the file format to PDF. Alternatively, you can head back to our PDF Converter, upload the Word document, and it will automatically be converted back to PDF.

After converting back to PDF, review the document to make sure the spacing is consistent.

Keep an eye on text alignment and font size. Sometimes small tweaks to these can make a big difference in how good your document looks.

If your PDF doesn’t look quite right after conversion, a few quick fixes can help.

This often happens if the original PDF used embedded fonts. Try selecting all text in Word, choose a standard font (like Arial or Calibri), and reapply single spacing before saving again.

Word may interpret paragraph breaks as double spacing. Use Ctrl + A to select all, then set “Line and Paragraph Spacing” to 1.0 and “Spacing Before/After” to 0 pt.

If margins or alignment shift, use the Print to PDF option in Word instead of “Save As.” It often preserves layout more accurately.

Form fields in most PDFs use fixed formatting. You can’t adjust spacing unless they’re Rich Text fields. In that case, open the PDF in an editor that supports formatting and reset spacing manually.

If you’re wondering why Smallpdf and Word are the right combo for this, here’s why:

• They’re super easy to use. You don’t need to be a tech expert to get the job done.

• The tools are quick and secure, so your files are safe while you work.

• Smallpdf works on any device, so you can convert PDFs whether you’re on a computer, phone, or tablet.

Plus, Smallpdf is free for basic tasks like converting, splitting, merging, and compressing PDF files.

Word lets you adjust the space before and after paragraphs. Use the “Spacing Before/After” controls in the paragraph formatting menu.

Need to adjust the space between letters? In Word, use the “Character Spacing” option under the Advanced tab in Font settings.

Adjusting line spacing in fillable PDF forms is tricky because of how PDF form fields work. Most form fields have fixed formatting based on the ISO 32000 specification. However, if your form uses Rich Text fields (multiline text fields with formatting options), you might be able to adjust spacing.

Pro tip: Try adding a space character at the beginning or end of your text in form fields. Sometimes this helps preserve the formatting you want.
