PowerPoint 97-2003 saved presentations as .ppt files, a binary format that newer programs, phones and online editors often refuse or open badly. This page converts them to .pptx, the format PowerPoint has used since 2007, without PowerPoint and without uploading anything: it reads the old file and writes the new one in your browser. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and while the page stays open, a feature you have already used keeps working offline.
Text stays text. Every title, bullet list and text box becomes a .pptx text box you can edit, with its font, size, bold, italic, underline, colour, alignment, bullets and indent levels written out in full, so it looks the same without the old file's slide master. Shapes keep their kind (rectangles, ovals, arrows, stars, flowchart shapes and so on), fill, outline, arrowheads and rotation; freeform drawings keep their outline; groups stay groups. Pictures go in as they were stored - JPEG, PNG, and Windows metafiles (EMF and WMF) - and older bitmap pictures become PNG.
- Will the .pptx look exactly like the .ppt?
- Very close for text, shapes and pictures. A few things are not carried over: animations and slide transitions, sounds and videos, and the slide master itself - its background pictures, decoration and any footer, date and slide number are copied onto each slide (behind the slide's own shapes) as ordinary text and shapes, so a slide number will not renumber itself if you reorder the slides. Charts, equations and other embedded objects come across as the picture PowerPoint saved of them, so they look right but cannot be edited as charts.
- Can it convert a password-protected .ppt?
- No. A .ppt saved with a password to open is encrypted, and this page says so rather than guessing. Open it in PowerPoint with the password, remove the password (File, Info, Protect Presentation) and save it, then convert that copy.
- Does it work with files from PowerPoint 95 or earlier?
- Not those: PowerPoint 95 and older used a different format. A file saved "for PowerPoint 95 and 97" carries a 97-2003 copy inside, and that copy is converted. Files saved as .ppt by PowerPoint 97 to 2019, LibreOffice and OpenOffice all work.
- Do I need fonts installed?
- No, but the .pptx names the same fonts the .ppt used. If your computer does not have one, PowerPoint shows a similar font, just as it would with the original file.
- Can I just look at a .ppt, or make a PDF of it?
- Yes. The PowerPoint Viewer opens .ppt files to read, present and print, and PowerPoint to PDF turns them into PDFs, both in your browser.
- Is my .ppt file uploaded to be converted?
- No. The .ppt is read and the .pptx is written on your computer, in the browser tab. Nothing is sent to a server, so confidential decks stay with you.
