RawToHEIC: One-Tap RAW to HEIC Conversion Right Inside Apple Photos, Shrinking File Size by 10x

The Photographer's Storage Dilemma

For photography enthusiasts who shoot ProRAW on iPhone and iPad, or import camera RAW files into the Apple ecosystem, storage space has always been an unavoidable pain point. A single RAW photo can easily reach tens of megabytes, and even Apple's own ProRAW format takes up significantly more space than standard photos. Once hundreds or thousands of RAW files accumulate in your photo library, storage pressure builds up fast.

RawToHEIC, recently launched on Product Hunt, targets exactly this niche need. Its core function is straightforward: convert RAW and ProRAW files to HEIC format directly within Apple Photos, reducing file size by up to 10x. The product garnered 70 upvotes after launch, ranking 11th on the daily leaderboard in the Photography category.

Key Highlights: Seamless Integration and Local Processing

Deep Integration with the System Share Sheet

RawToHEIC's most clever design choice is its deep integration into the system Share Sheet. Users don't need to open a standalone app — simply select RAW photos in the Photos app and trigger the conversion through the standard share action. This design dramatically lowers the barrier to use, embedding the conversion process into users' existing workflows across iPhone, iPad, and Mac.

Compared to traditional third-party conversion tools that require exporting, processing, and re-importing, this "convert in place" experience is far smoother. For users who regularly need to batch-process RAW files, the efficiency gains are significant.

Full Preservation of Edit History, Album Organization, and Metadata

Notably, RawToHEIC promises to preserve photos' edit history, album assignments, and metadata during conversion. This is especially important for photography professionals — format conversion often risks losing shooting parameters (EXIF), GPS location data, or post-processing adjustments. RawToHEIC's commitment to fully preserving this information shows it's more than a simple compression tool — it maximizes photo integrity while saving space.

A Privacy-First Design Philosophy

In an era of growing data privacy awareness, RawToHEIC emphasizes its fully local processing approach: all conversions happen on-device, no data is uploaded to the cloud, no account registration is required, and there's no analytics or tracking whatsoever.

This design aligns perfectly with Apple's longstanding commitment to privacy protection. For users with large libraries of personal photos, there's no need to worry about images being uploaded to third-party servers or deal with tedious account registration. This "zero trust cost" positioning creates a clear differentiator among similar RAW conversion tools.

The Advantages of HEIC and the Conversion Trade-offs

Why HEIC?

HEIC (High Efficiency Image Container) is the high-efficiency image format Apple adopted starting with iOS 11, based on HEVC encoding technology. It can compress files to roughly half the size of JPEG while maintaining comparable image quality. Compared to RAW files, the compression ratio is even more impressive. RawToHEIC's claim of "up to 10x size reduction" leverages HEIC's significant compression efficiency advantage.

Trade-offs Worth Understanding

That said, users should understand the trade-offs behind converting RAW to HEIC. RAW files are large precisely because they retain the raw sensor data, providing maximum latitude for post-processing adjustments. Once converted to HEIC — while still a relatively high-quality format — the result is essentially lossy compression, and some degree of post-editing flexibility is inevitably lost.

Therefore, RawToHEIC is best suited for photos that have already been post-processed and are ready for archival to save space, or for everyday shots where ultimate image quality isn't critical. For professional creative assets that require deep post-processing, keeping the original RAW files remains the safer choice.

Summary: A Small but Precisely Targeted Tool

RawToHEIC is a quintessential "small but beautiful" utility product. Rather than chasing feature bloat, it precisely solves a specific pain point for Apple ecosystem users dealing with RAW file storage. Its seamless Share Sheet integration, meticulous metadata preservation, and thorough local-processing privacy commitment together form the product's core competitive strengths.

Built by indie developer Sandro Gumz, RawToHEIC also demonstrates the ability of independent developers to uncover user needs in niche scenarios. For iPhone photography enthusiasts perpetually haunted by storage warnings, it offers a solution worth trying. Of course, whether to adopt it still depends on your personal balance between image quality and storage space.
