How do I edit the slides after converting to HEIC?

PPS is PowerPoint's legacy slideshow format, distinct from .ppt in one specific way: double-clicking a .pps file opens it directly in presentation mode rather than the editor. It was the standard distribution format for kiosk decks, training videos, email chain forwards (those animated motivational slideshows your aunt sent in 2005), and conference handouts through the early 2000s. The underlying binary is identical to .ppt; only the file association changes Windows' default action.

Converting .pps to HEIC turns a slideshow into a static image-per-slide bundle in the modern HEVC-compressed format - useful when archiving decks for long-term storage where the .pps binary may not survive software changes, and where HEIC's roughly 50% size saving over JPG compounds across a big deck library. heic.now reads the legacy BIFF-style structure, renders each slide at its native aspect ratio (usually 4:3 for pre-2007 decks), and outputs a HEIC sequence. Embedded images, basic shapes, and text render with high fidelity; animations flatten to their first frame.

Common users include training departments archiving old onboarding decks, marketing teams pulling slides out of competitor materials for analysis on their MacBooks and iPads, and archivists digitising conference materials from CD-ROM era proceedings. For PowerPoint 2007+ slideshows, our .ppsx converter handles the OOXML variant. To produce a portable bundle, follow up with /heic-to-pdf; for recipients on Windows PCs without the HEVC codec, route through /heic-to-jpg.

Reasons to convert PPS to HEIC usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts HEIC uploads.
• You need a feature unique to HEIC (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that PPS doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the PPS → HEIC tool on heic.now.
2. Drag your PPS file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to HEIC. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• If the .pps was created in PowerPoint 95 or 97, expect more font substitution - Microsoft has changed bundled fonts repeatedly.
• Embedded WMF or EMF metafiles render correctly; older versions sometimes used proprietary clipart that may degrade.
• Speaker notes are not visible in the HEIC output - export to PDF from PowerPoint first if notes matter.
• Auto-advance timings and transitions are ignored; each slide becomes a static image.
• For slides with embedded audio narration, the audio is silently dropped - a still image carries no sound.
