How to Convert PowerPoint to Google Slides for Free

Need to know how to convert PowerPoint to Google Slides without paying for another app? Upload the PPT or PPTX file to Google Drive. The presentation is converted during upload and appears with the yellow Google Slides icon, ready to open and edit.

The process is free with a Google account and works without PowerPoint installed. Keep the original PowerPoint file on your device until you’ve reviewed the converted deck. Custom fonts, text boxes, embedded media, complex diagrams, and some animations might still move or change.

Google Drive handles the PowerPoint-to-Google-Slides conversion during upload, so you no longer need to open a preview or save a separate Slides copy. The steps work for both PPT and PPTX files.

Step 1: Check the PowerPoint File

Open the deck before uploading it, if you can. Make sure the slides load correctly and remove anything you no longer need, such as hidden slides, unused media, or duplicate layouts.

You should also note the slide size. A standard presentation may use 4:3, while many newer decks use 16:9. Knowing the original resolution makes it easier to spot a layout change after conversion.

If the file is larger than 100 MB, reduce its media or split it before trying again.

Create a PDF Backup (Smallpdf)

Before uploading the presentation to Google Drive, save a PDF copy with Smallpdf’s PPT to PDF tool. This gives you a fixed version of the original slides that you can use to compare fonts, spacing, images, and layouts after conversion.

• Upload your PPT or PPTX file to Smallpdf PPT to PDF or drop the file in the drop area below

• Download the converted PDF and keep it with your original presentation.

• Use the PDF as a visual reference to compare fonts, spacing, images, and layouts after converting to Google Slides.

Step 2: Upload the PPT or PPTX to Google Drive

1. Sign in to Google Drive on your computer.

2. Click “New.”

3. Choose “File upload.”

4. Select the PowerPoint file from your device.

5. Wait for the upload to finish.

Step 3: Open and Review the Converted Presentation

Double-click the file with the yellow Google Slides icon. It should open directly in the Slides editor. Rename it if needed, then run through the presentation before you edit, present, or share it. Don’t assume every slide made the trip perfectly. Run the presentation from beginning to end and check:

• Text boxes, line breaks, and bullet spacing

• Fonts, colors, and background images

• Charts, diagrams, and SmartArt

• Videos, audio, animations, and transitions

• Speaker notes and clickable links

Open the original PowerPoint file from your device beside the Google Slides version when something looks wrong. This makes it easier to see whether an object moved during conversion or was already out of place. Pay close attention to overlapping text boxes, changed line breaks, cropped images, and objects that have shifted off the slide.

PowerPoint and Google Slides use different font libraries, media handling, animation controls, and layout systems. Simple decks often convert cleanly. A heavily designed presentation may need a few repairs.

Issue 1: Fonts Were Replaced

A font can change when it isn’t available in Google Slides. The substitute may be wider, narrower, taller, or shorter, which can push text onto another line and move nearby objects.

• Fix: Select the affected text and choose a similar font from the Slides font menu. Then check the font size, line spacing, and text box width. For future conversions, use a font available in both environments before uploading the deck.

Check headings first. One substituted heading font can create different line breaks across dozens of slides.

Issue 2: Text or Images Moved

Text may overflow a box, crop differently, or sit too close to another object after a PPTX-to-Google-Slides conversion. The font substitution may be responsible, but the slide size or original layout can also cause it.

• Fix: Start with “File,” then “Page setup” and confirm that the presentation uses the right ratio. Google Slides supports Standard 4:3, Widescreen 16:9, Widescreen 16:10, and custom sizes.

Next, resize the text box rather than shrinking the text immediately. A small box change often fixes the slide without making the copy harder to read. Reposition images last, once all the text is stable.

Issue 3: Videos or Audio No Longer Work

Embedded PowerPoint videos don’t stay playable during Office-file editing in Google Slides. Embedded charts and videos in PowerPoint files are converted to images.

• Fix: Upload the video to Google Drive or use a supported online source, then choose “Insert,” and “Video” in Google Slides. Slides can add video from YouTube, a URL, or Google Drive. For audio, upload an MP3 or WAV file to Drive and insert it from there.

Test the media while signed in and again through the same sharing permissions your audience will use. A video stored in Drive may fail for someone who doesn’t have permission to open it.

Issue 4: Animations or Transitions Changed

Some PowerPoint effects have no exact Google Slides match. Others may transfer but play with different timing or behavior. Certain Slides animations may also not work in some browsers.

• Fix: Open “View,” then “Motion” and rebuild the affected animation with a supported option. Keep it simple where possible. An appear, fade, or basic slide transition is usually easier to test than a sequence of overlapping effects.

Run the slideshow rather than checking only in the edit view. Timing problems often become obvious only during playback.

Issue 5: SmartArt or Charts Became Harder to Edit

Google converts SmartArt into Google Drawings, while embedded charts may become images. The slide can still look close to the original, but you may lose the editing controls you had before conversion.

• Fix: Leave the object as an image when you only need to present it. If the figures will change, rebuild the chart with Google Sheets and place it in Slides, or recreate the diagram with native shapes. That takes longer once, but it saves you from worrying about later updates.

You can open and edit PowerPoint files on a phone or tablet with the Google Slides app. On iPhone and iPad, the app imports PPT and PPTX files. On Android, it imports PPT, PPTX, and ODP files.

A simple mobile workflow would be:

1. Replace the current numbered steps with:

2. Open the Google Drive app.

3. Tap the “+” button and choose “Upload.”

4. Select the PPT or PPTX file from your device.

5. Wait for the upload and conversion to finish.

6. Look for the yellow Google Slides icon, then tap the file to open it.

7. Review the slides before editing or sharing the presentation.

The mobile apps are useful for quick edits, but a computer is better for comparing versions and fixing a complex layout. The larger screen gives you clearer control over themes, page setup, media, and animations. It’s also easier to spot overlapping text boxes, cropped images, and other layout changes.

For a presentation with custom fonts, videos, detailed charts, or tightly placed objects, do the first full review on a larger screen. Then use your phone for small changes, comments, or presenting.
