Turn each slide of a PowerPoint deck into a flat HEIC image — Apple's High Efficiency Image Format, which stores a slide at roughly half the size of an equivalent JPEG. This is the right pick when the images are headed for an iPhone, iPad, or Mac photo library; if they need to open anywhere, see the compatibility note below before you commit. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
How to Convert PPTX to HEIC
- Upload Your PPTX File: Drag and drop your
.pptxonto the page or click "+ Add Files" to browse. Each slide becomes one HEIC image. - Pick a Quality Preset: Choose from Lowest to Highest under Advanced Options; "Very High" is the recommended default and keeps slide text and charts crisp.
- Set Image Resolution (Optional): Use Image resolution or Resolution Percentage to scale the rendered slides up for print or down to shrink the output further.
- Convert and Download: Click "Convert" and save your HEIC files. No sign-up, no watermark.
Should You Use HEIC, or JPG/PNG Instead?
HEIC opens natively only on Apple devices and in Safari 17 and later — Chrome, Firefox, Edge, and every Android browser cannot display it. Use this table to decide before converting.
| If your slides are for… | Best output | Why |
|---|---|---|
| iPhone / iPad / Mac photo library | HEIC | Native support; ~50% smaller than JPEG at equal quality |
| Sharing with anyone, any device | JPG | Universal support across every browser and OS |
| Logos, diagrams, sharp-edged text | PNG | Lossless, no JPEG/HEVC artifacts on hard edges |
| Already have HEICs to send out | HEIC → JPG | Converts back for non-Apple recipients |
Frequently Asked Questions
Why would I convert slides to HEIC instead of JPG?
Storage and Apple integration. HEIC uses HEVC compression, which the format's developers measured at roughly 50% fewer bits than JPEG for the same visual quality, so a deck exported as HEIC takes about half the space of the JPEG equivalent. If those images live in an iOS or macOS Photos library, HEIC is also the native format Apple already uses for camera photos.
Will HEIC slides open on Windows or Android?
Not by default. HEIC displays natively only on Apple platforms and in Safari 17 or later; Chrome, Firefox, Edge, and Android browsers do not decode it. Windows can add support through the HEVC extension from the Microsoft Store. If the recipient's device is unknown, convert to JPG instead, or send a HEIC and let them run HEIC to JPG on their end.
Does HEIC keep transparent backgrounds from my slides?
The HEIF specification (ISO/IEC 23008-12) does support an alpha plane for transparency, but PowerPoint slides render on an opaque canvas, so the exported image is flat with a solid background. If you specifically need a transparent slide element, export that object to PNG, which carries true alpha across all browsers.
What quality preset should I choose for text-heavy slides?
Use "Very High" or "Highest." HEVC is a lossy codec, and aggressive compression can soften small fonts and chart gridlines. In our testing, a standard 1920x1080 slide at the "Very High" preset stayed visually sharp while landing well under the size of the same slide saved as a maximum-quality JPEG.
How large a PPTX can I upload?
There is no fixed slide-count cap; the practical limit is upload size and your connection speed, since the file travels to our servers for rendering. A typical business deck of 20-50 slides is small and converts quickly. Very large decks with many high-resolution embedded photos take longer mainly because of upload time, not the conversion itself.
