Free online PPTM to TIFF converter

Some publishing, imaging, and archiving workflows accept TIFF images but not macro-enabled PowerPoint presentations. Converting the slides produces raster files that can be viewed or placed in documents without requiring PowerPoint.

What PPTM is

PPTM is the macro-enabled presentation format used by Microsoft PowerPoint. It stores slides and can contain embedded VBA macros; PowerPoint is its primary creator and editor. You may receive it when someone shares a presentation that includes macros or saves a PowerPoint deck in macro-enabled format.

What TIFF is

TIFF is a raster image format used in scanning, publishing, and image archiving. It supports high-resolution images and lossless compression such as LZW, making it useful when image quality matters. A converted presentation is rendered as slide images: text and graphics are no longer individually editable, and animations are not preserved.

How to convert

Online on 101convert.com

1. Upload the PPTM file on the 101convert.com converter page. You can add several files for batch conversion; the per-file size limit is shown on the page.
2. Choose TIFF and, if needed, set pages, resolution, image size, max width, max height, auto orient, or strip metadata.
3. Start the conversion and download the resulting TIFF file or files.

The conversion runs on the server with LibreOffice, then ImageMagick.

Offline with desktop software

LibreOffice Impress and ImageMagick are free options available for Windows, macOS, and Linux. In Impress, open the PPTM and use File → Export, select TIFF, and save; if prompted, choose whether to export the current slide or all slides. For command-line conversion of every slide, export a PDF and rasterize its pages:

1. Export the presentation: libreoffice --headless --convert-to pdf --outdir out deck.pptm
2. Create TIFF files at 300 dpi with LZW compression: magick -density 300 out/deck.pdf -compress LZW out/slide-%03d.tif

ImageMagick needs a PDF-reading delegate such as Ghostscript enabled to rasterize the PDF. Change 300 to adjust output resolution.

Microsoft PowerPoint for Windows: open the presentation, choose File → Save As, select TIFF as the file type, and save. When prompted, choose the current slide or all slides.

Quality and limitations

TIFF resolution determines how sharply slide text and diagrams render, especially when enlarged or printed. Check the output for substituted fonts or altered effects if it was rendered in software other than PowerPoint. The images contain the saved slide appearance, not VBA macros, transitions, or animation behavior.
