About this tool
PowerPoint to PDF should preserve slide size and fonts. This version does not import pptx into a layout it can stand behind, so it will not emit a PDF and hope. Export from the presentation program on this device when the slides must match. If you already have a PDF of the slides and it is huge because every slide is a picture, Compress PDF is the tool that can help.
PowerPoint to PDF stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: the presentation is not uploaded for a conversion this version cannot verify.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
FAQ
Does “PowerPoint to PDF” upload my file?
PowerPoint to PDF reads the file in this tab. There is no upload step and no account.
What will “PowerPoint to PDF” actually change?
No slide is rasterized by this tool. Use the presentation app’s export for a faithful PDF.
When is “PowerPoint to PDF” the wrong job?
A huge exported PDF is a compression problem. Open Compress PDF for that, not a second converter.
How do I check the result of “PowerPoint to PDF”?
Do not expect a download from this screen. Check a PDF from the original app full-screen against the slides.
Can I run “PowerPoint to PDF” with Wi-Fi off?
Load this page, then turn Wi-Fi off and run PowerPoint to PDF again. A finished result is the proof that the file was not sent anywhere.
