Frequently Asked Questions
What image size is best for PowerPoint?
For widescreen slides (16:9), use 1920x1080 pixels. For standard slides (4:3), use 1024x768 pixels. These dimensions fill the entire slide without any stretching or quality loss.
Why is my PowerPoint file so large?
Large PPTX files are usually caused by oversized images. PowerPoint embeds images at full resolution. Resize images to slide dimensions (1920x1080) and compress them before inserting to keep file sizes manageable.
Does PowerPoint compress images?
PowerPoint has a built-in compression feature (File > Compress Pictures), but it's better to resize and optimize images before inserting them. This gives you more control over quality and file size.
Should I use JPEG or PNG in PowerPoint?
Use JPEG for photographs (smaller file size). Use PNG for charts, diagrams, logos, and images needing transparency. This combination keeps your presentation looking sharp while managing file size.
