For labels with pictures, the best format depends on whether the goal is view/print or keep editing:
- PDF is the best format to preserve the layout and print quality of existing Publisher labels. Publisher can save to PDF, and PDF is preferred for high-quality printing.
- PDF is not editable in Publisher. After saving to PDF, the file is mainly for viewing, sharing, and printing.
- If editing must continue in Microsoft 365 after Publisher retirement, the supported path is to move the labels into Word.
A practical approach for picture-based labels is:
- In Publisher, save the existing label publication as PDF to preserve the original design.
- If individual label elements or pages need to be reused, save them as PNG or JPEG picture files. For best results, use High quality printing or commercial press (300 dpi).
- Rebuild the editable label layout in Word.
- In Word, insert the picture into the label, then set Picture Format > Text Wrapping > Square, drag it into position, and add the text.
- If a full sheet of identical labels is needed, create one label first, then use Mailings > Labels > New Document again to repeat it across the sheet.
Format guidance for pictures:
- PNG: good choice for line art, logos, and graphics; supported in Office.
- JPEG: good choice for photos.
- TIFF: suitable for desktop and commercial printing, but larger files.
- Avoid excessively high image resolution because pictures above 1,000 ppi may not print at all.
If the question is specifically which single format is best to convert Publisher labels with pictures into for future editing, the closest supported answer is:
- PDF for preservation
- Word for ongoing editing
- PNG for label graphics when reusing images inside Word
