HEIC vs PPM — Comparison & Free Converter
Fast, instant HEIC to PPM conversion. No signup required. Just drop your .heic file and get .ppm in seconds.
Batch Settings
HDR data will be tone-mapped
Your HEIC file may contain HDR (High Dynamic Range) data. PPM only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Converting to PPM won't restore lost quality
Your HEIC file has already undergone lossy compression. Converting to PPM preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Animation frames will be lost
HEIC supports animation, but PPM does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your HEIC file may contain EXIF, XMP metadata. PPM has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Wide color gamut → sRGB
Your HEIC file uses a wide color gamut (Display P3, sRGB). PPM uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.
Default format on iPhone 7+ (iOS 11+)
Your device saves files in HEIC by default (iPhone 7+ (iOS 11+), iPad Pro 2017+, macOS High Sierra+). Most people convert because the files won't open on other devices — PPM is universally supported and will work everywhere.
About HEIC to PPM Conversion
HEIC or PPM — which format should you use? The answer depends on your needs. Here's a quick breakdown.
HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG. It has limited platform support. PPM (Portable Pixmap) is a simple uncompressed image format used in scientific imaging. It has niche platform support.
Full Name: HEIC uses High Efficiency Image Container, while PPM uses Portable Pixmap. Compression: HEIC uses Lossy, while PPM uses None (uncompressed). Transparency: HEIC uses No, while PPM uses No.
So when should you convert HEIC to PPM? This conversion is ideal when you You captured this file on iPhone 7+ (iOS 11+) and need to share it with others. This conversion helps you preserve files for long-term archival.
Your HEIC file may contain HDR (High Dynamic Range) data. PPM only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Common misconception: ""Converting HEIC to PPM will improve the quality"" — in reality, no. heic has already permanently discarded data during compression. converting to ppm preserves what's left but cannot restore lost detail. the file will just be larger.

What Happens When You Convert HEIC to PPM
Your HEIC image is decoded into raw pixel data, then re-encoded as PPM. Current quality is preserved as-is — no further degradation.
Your HEIC file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where PPM supports it
The PPM file is saved and ready for download

Should You Convert HEIC to PPM?
When to Convert
- ✓You captured this file on iPhone 7+ (iOS 11+) and need to share it with others
When NOT to Convert
- ✗You're hoping to improve image/audio quality — converting lossy to lossless cannot recover lost data
- ✗You want to preserve HDR information — PPM only supports standard dynamic range
Common Mistakes When Converting HEIC to PPM
"Converting HEIC to PPM will improve the quality"
No. HEIC has already permanently discarded data during compression. Converting to PPM preserves what's left but cannot restore lost detail. The file will just be larger.
"PPM will be smaller than my HEIC file"
PPM uses no compression, so the output file is often larger than a lossy HEIC. If you need a small file, PPM may not be the right choice.
"My animated HEIC will stay animated after conversion"
PPM does not support animation. Only a single frame will be saved. Use WebP or GIF to preserve animation.
Frequently Asked Questions
Should I use HEIC or PPM?
It depends on your goal. HEIC offers smaller files via lossy compression. PPM preserves full quality. Choose based on whether file size or quality matters more for your use case.
Is PPM higher quality than HEIC?
Not necessarily. Your HEIC file may contain HDR (High Dynamic Range) data. PPM only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Quality depends on the compression type and settings, not just the format name.
Can I convert HEIC to PPM on Mac and Windows?
Yes. CocoConvert is a web-based tool that works in all modern browsers — Chrome, Safari, Firefox, Edge — on any operating system including macOS, Windows, Linux, iOS, and Android.
Is CocoConvert free for HEIC to PPM?
Yes. Free users get 5 conversions per hour (250 MB each). Pro subscribers unlock 100 files per hour, 5 GB per file, and priority processing.
What tools does CocoConvert use for HEIC to PPM?
CocoConvert uses FFmpeg for audio/video, Sharp for images, and qpdf for documents — the same open-source libraries used by Netflix, YouTube, and major enterprise platforms.
