Frequently Asked Questions
Q: Can I upload files from cloud storage like Google Drive?
A: Not yet, but it's on our roadmap. For now, download from the cloud to your device, then upload to RunConvert.
Q: Will my fonts be preserved during conversion?
A: We try to keep them intact, but sometimes font substitutions happen—especially if you used something super niche. Embedding fonts before upload can help.
Q: Will password-protected presentations convert?
A: Only if you unlock them first. We can’t access files that are password-protected for editing or viewing.
Q: What happens if the file doesn't convert properly?
A: It’s rare, but if it happens—don’t sweat it. Try uploading again or reach out to our support team. We’re humans behind the screen, and we’ll help.
Q: Does RunConvert compress files during conversion?
A: Yes, most of the time. Especially when going from .pptx to PDF, we apply smart compression to keep the quality without bloating the size.
Q: Will speaker notes be visible in image conversions?
A: Nope, image formats show only the slide itself—notes stay behind the curtain.

A: Sure! Convert to JPEG or PNG, crop them square, and you’ve got instant content. Perfect for carousel posts.
