Next-Generation Format

HEIF represents the cutting edge of image compression — your PPSX slides are stored in a format designed to replace JPEG with better quality at smaller sizes.

Slides to Modern Images

Move PPSX presentation visuals into the HEIF ecosystem — producing images that are future-proof, feature-rich, and compatible with the latest devices and software.

Server-Side Rendering

Conversion runs on Convertio infrastructure. No HEIF encoder or codec pack required on your device — upload the PPSX and download polished HEIF images.

About formats

PPSX (PowerPoint Slideshow XML) is the Open XML counterpart to the legacy PPS format, introduced by Microsoft with Office 2007. Like PPTX, a PPSX file is a ZIP archive containing XML parts that describe slides, layouts, themes, and media assets according to the Office Open XML specification. The distinguishing characteristic is behavioral: opening a PPSX file launches the presentation directly in full-screen slideshow mode, bypassing the editing environment. This makes PPSX the preferred format for distributing finalized presentations where the audience should experience the content as a seamless visual narrative without exposure to the editing interface, slide sorter, or speaker notes panel. PPSX files support every visual feature available in PPTX including transitions, animations, embedded video and audio, hyperlinks, SmartArt, charts, and custom slide timings. One advantage is streamlined delivery — a PPSX file attached to an email or shared via a link opens as a polished presentation with a single click, requiring no instruction to the recipient. The XML-based foundation provides another benefit: PPSX files are typically much smaller than equivalent PPS files due to built-in ZIP compression, and their contents can be inspected or modified programmatically using standard XML tools. The format is supported for playback in PowerPoint, LibreOffice Impress, Google Slides (after upload), and various mobile presentation apps, ensuring broad cross-platform reach for distributed slide decks.

HEIF (High Efficiency Image File Format) is a container format for images and image sequences standardized by the Moving Picture Experts Group as ISO/IEC 23008-12, first published in 2015. HEIF is built on the ISO Base Media File Format (ISOBMFF, the same container used for MP4 video), providing a flexible structure that can hold single images, image collections, image sequences (like animations or bursts), and derived images with non-destructive editing operations. The container is codec-agnostic — while the most common implementation pairs HEIF with HEVC/H.265 compression (branded as HEIC by Apple), the standard also accommodates AV1 compression (creating the AVIF variant), H.266/VVC, and other future codecs. HEIF supports features that JPEG lacks: 10-bit and 12-bit color depth, wide color gamuts (Display P3, BT.2020), lossless compression, alpha transparency, depth maps, thumbnail images, and Exif/XMP metadata — all within a single file. Auxiliary image items can store computational photography data like depth maps, HDR gain maps, and semantic segmentation masks. One advantage is the format's future-proof architecture: by separating the container from the codec, HEIF can adopt newer, more efficient compression technologies without changing the file structure, metadata handling, or application-level APIs. The substantial compression improvement over JPEG is another core strength — HEVC-based HEIF typically achieves 40-50% file size reduction compared to JPEG at the same visual quality, beneficial for storage and bandwidth. HEIF is supported by Apple's ecosystem (iOS, macOS), Windows 10/11, Android 10+, GIMP, ImageMagick, and Adobe products.

Frequently Asked Questions

Why convert PPSX to HEIF?

HEIF stores images at dramatically smaller sizes than JPEG without visible quality loss. It is the modern standard for efficient image storage across mobile and desktop platforms.

How do I open HEIF files?

macOS, iOS, Windows 10/11 (with extension), and Android 9+ support HEIF. Adobe Lightroom, GIMP 2.10+, and most modern photo editors also handle the format.

How is HEIF different from HEIC?

HEIF is the container format defined by MPEG. HEIC is a specific HEIF profile using HEVC compression — commonly used on Apple devices. Both terms often refer to the same thing.

Does HEIF support image sequences?

Yes — HEIF can store multiple images, depth maps, and even short animations in a single file. However, PPSX slide conversion produces one standalone HEIF image per slide.

Can HEIF store metadata?

HEIF supports EXIF, XMP, and MPEG metadata. Conversion from PPSX generates standard image metadata, though presentation-specific data like speaker notes is not carried over.

Is PPSX to HEIF conversion free?

Yes — Convertio converts PPSX to HEIF at no charge. Premium accounts unlock bigger uploads and priority in the processing queue.
