Quality reduction ahead
PPTX is lossless, meaning every bit of data is preserved. JPEG uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your PPTX file may contain Office XML properties metadata. JPEG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
JPEG lossy compression can produce blockiness and mosquito noise around sharp edges. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

Frequently Asked Questions
Why won't my PPTX file open?
PPTX files may not open if your device lacks the right codec or application. Converting to JPEG — a more widely supported format — usually resolves this. JPEG uses lossy compression optimised for photographic content, balancing quality against file size.
Is it safe to convert PPTX to JPEG online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting PPTX to JPEG?
