Convert PowerPoint to PDF Online Free
To convert PowerPoint to PDF with PdfPeaks, upload your PPT or PPTX file, click Convert to PDF and download the result. Each slide becomes a fixed PDF page. Animations don't play and speaker notes aren't included as separate pages. It's free, needs no account and accepts files up to 100 MB.
There are a few moments when sending a .pptx file is a bad idea. A conference organiser asks for slides as a PDF. A university portal rejects anything that isn't a PDF. A client opens your proposal on a laptop without your fonts and the whole deck reflows into something you didn't design. In each case, a PDF is the answer. It keeps every slide exactly where you put it and opens the same way everywhere.
PdfPeaks converts PPT and PPTX presentations to PDF in your browser. Upload the deck, press Convert to PDF and download the file. There's no account to create and nothing to install, and you don't need PowerPoint on the device you're using. People do this from a phone on the way to a meeting more often than you'd think.
Behind the scenes the conversion runs on LibreOffice. That's worth knowing because it explains the one thing that occasionally goes wrong: if your deck uses a font that isn't available on our server, a similar font is swapped in and the text can shift slightly. The simple fix is to embed fonts in your presentation before uploading, and the Tips section below shows where that setting is. Standard fonts like Arial, Calibri and Times New Roman rarely cause any trouble.
A PDF is a snapshot. Animations and transitions won't play, and embedded video becomes a still image. For most uses that's what you want. A reviewer reading slides doesn't need your fly-in effects. If you need to go the other direction, turning a PDF back into editable slides, use PDF to PowerPoint at https://pdfpeaks.com/pdf/converttopowerpoint.

How It Works
Step 1: Upload your presentation. Drag a .ppt or .pptx file into the upload box, or tap Select PowerPoint and pick it from your phone or computer. Presentations up to 100 MB are accepted.
Step 2: Click Convert to PDF. Decks with large photos or embedded media take longer than a plain text deck, so give a heavy file a minute.
Step 3: Download the PDF. Open it and flip through before you send it. Check the title slide and any slide with a chart or a custom font, because those are where differences show up first.
- Step 4: Finish it off if you need to. A deck full of photos often produces a big PDF, so run it through Compress PDF at https://pdfpeaks.com/pdf/compress if you're up against an email or portal limit. Add slide numbers with https://pdfpeaks.com/pdf/addpagenumbers, stamp a DRAFT mark with https://pdfpeaks.com/pdf/watermark, or combine several decks into one handout with https://pdfpeaks.com/pdf/merge.
Security & Privacy
Presentations are often unfinished or confidential: a pitch to investors, a client proposal, results nobody has seen yet. Your file is sent to our server over an encrypted HTTPS connection, converted, and deleted once processing is done. It isn't used to train anything and it isn't shared. The full wording is in our privacy policy at https://pdfpeaks.com/home/privacy.
Before you send any PDF out, remember what a PDF can still carry. Text on the slides is readable and copyable, and hidden slides in the original deck may or may not appear, so look through the finished file. If a deck contains something that must stay private, like a client name on a slide you only half-deleted, fix it in PowerPoint and convert again. If you need to lock the finished file, https://pdfpeaks.com/pdf/protect adds a password.
Common Use Cases
Conference and seminar submissions: Organisers collect slides as PDFs so they can load every talk onto one machine. Converting your own deck means you control how it looks.
University presentations and thesis defence: Many departments want a PDF copy for the record. It also makes a safe backup if the projector computer misbehaves.
Class handouts and lecture notes: Teachers convert the day's slides and upload them to the learning system or share them in a class group. Students on phones can read a PDF far more easily than a PPTX.
Client proposals: A PDF can't be casually edited by whoever you forward it to, and it won't reflow on their screen.
Job interviews and portfolios: Some employers ask for a presentation as a PDF. Send the deck you designed, not the one their computer renders.
Printing: Print shops handle PDFs reliably. Set the slide size and margins in PowerPoint, convert, and the print comes out the way you saw it.
Business and board reports: Finance and strategy decks are shared as read-only PDFs, often with page numbers and a confidential stamp added afterwards.
Archiving final versions: A finished deck saved as a PDF will still open the same way in five years. A PPTX might not.
Sharing on WhatsApp or email: A PDF is smaller and more predictable than a deck full of embedded fonts and linked files.
Tips for Best Results
Embed your fonts. In PowerPoint, go to File, Options, Save, and tick Embed fonts in the file. It's the single best thing you can do for a faithful conversion, particularly if you use a font that isn't installed on every computer.
Use common fonts when you can. If a deck has to look identical everywhere, Arial, Calibri and Times New Roman are the safest choices.
Finish animations in their final state. Because a PDF is static, each slide shows its end state. If a bullet only appears on a click, make sure the content you want is visible on the slide itself.
Don't rely on video. Embedded video and audio don't play in a PDF. If the clip matters, send it separately or add a link on the slide.
Speaker notes don't become pages. The converter outputs the slides as they look. If you want notes in the PDF, print the Notes Pages view from PowerPoint itself instead.
Check slide size. A 16:9 deck stays 16:9 and a 4:3 deck stays 4:3. If a portal wants A4, you'll need to change the slide size in PowerPoint before converting.
Reduce huge images first. In PowerPoint, Picture Format, Compress Pictures shrinks the pictures inside the deck. It often cuts the PDF size more than compressing the PDF afterwards.
Watch the file size limit. Many portals cap uploads at 1 MB, 2 MB or 5 MB. Convert first, check the size, then use https://pdfpeaks.com/pdf/compress if it's over. The walkthrough at https://pdfpeaks.com/blog/article/how-to-reduce-pdf-file-size shows how to hit exact targets.
Name the file clearly. Something like Surname_Topic_Slides.pdf is easier for the recipient to find than Presentation1_final_v3.pdf.
Keep the original. A PDF is the finished copy, so any changes should be made in the PPTX and converted again.
