📂 Batch Upload Rule
For multi-file uploads, all files in the same batch should use the same source type (for example all JPG or all MP3).
PPTX (Microsoft PowerPoint Open XML Presentation) is an editable slide presentation format. JPG (Joint Photographic Experts Group) is a compressed photo format. Try our Universal Converter for other file formats.
Quick rules and tips to get the best results.
For multi-file uploads, all files in the same batch should use the same source type (for example all JPG or all MP3).
Set your preferred output quality to balance file size and clarity. Compression behavior is tailored to each file format.
Each conversion request supports up to 200 MB total. Each user can upload a total of 500 MB per hour.
Completed jobs are saved on this device for up to 1 hour, unless you remove them from the list.
PPTX content is rendered through document export defaults and then written as JPG image output. For non-PDF office routes, this usually behaves like a preview export and returns one image per input file rather than guaranteed page-by-page extraction.
For PPTX to JPG, quality slider tuning is not exposed on this route, so export defaults determine compression behavior. If final clarity is not enough, verify source resolution and typography first, then compare one sample output before batch conversion.
Review text readability, chart labels, and slide or page framing in one converted sample. This quick check helps catch clipping, font fallback, or scaling issues before full batch delivery.
