About formats

ARW (Alpha RAW) is Sony's proprietary RAW image format used across the Alpha mirrorless and DSLR camera lineup, introduced in 2006 with the Alpha DSLR-A100. Built on a TIFF-like container structure, ARW stores the unprocessed readout from Sony's Exmor and Exmor R/RS CMOS sensors at 12 or 14 bits per pixel, retaining the complete dynamic range and color information before any in-camera processing is applied. The format includes detailed metadata — AF point data, lens distortion profiles, face detection results, and real-time tracking information from newer bodies — enabling RAW processors to replicate or refine the camera's processing decisions after the fact. ARW has evolved through several revisions: ARW 1.0 used simple per-row compression, ARW 2.0 introduced a more efficient delta encoding scheme, and ARW 4.0 added lossless compression support. One advantage is the exceptional latitude for exposure correction: Sony's sensor technology captures 14+ stops of dynamic range in many bodies, and the uncompressed ARW data preserves this range fully, allowing photographers to recover shadow detail or pull back highlights well beyond what JPEG permits. The format's integration with Sony's ecosystem is another practical strength — Creative Styles, Picture Profiles, and in-camera lens corrections are stored as metadata tags rather than baked into the data, giving photographers complete flexibility during post-processing. ARW files are supported by Adobe Lightroom, Capture One, DxO PhotoLab, and Sony's own Imaging Edge software suite.

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 ARW to HEIF?

HEIF stores images at high quality with dramatically smaller sizes than traditional formats — a practical step up from bulky Sony RAW originals.

What programs open HEIF?

HEIF is supported by Apple Photos, macOS Preview, iOS, Windows Photos (with codec), and Adobe Lightroom.

Can I convert multiple ARW photos at once?

Yes — batch upload is supported. Queue several Sony ARW images and convert them all to HEIF in one session without repeating the process.

Is the ARW to HEIF conversion free?

You can convert ARW to HEIF for free on convertio.tools. Larger or more frequent conversions are available with a subscription plan.

How quickly does ARW to HEIF conversion finish?

Most conversions complete within seconds. Larger files may take slightly longer, but cloud processing keeps it fast regardless of your device.
