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.

Initial release: 2006
PNG (Portable Network Graphics) is a lossless raster image format developed by the PNG Development Group and published as a W3C Recommendation on October 1, 1996, created as a patent-free replacement for GIF after the Unisys LZW patent controversy. PNG uses a two-stage compression pipeline: a prediction filter selects the optimal per-row preprocessing (none, sub, up, average, or Paeth), then DEFLATE compression encodes the filtered data. The format supports rich color modes — 1/2/4/8/16-bit grayscale, 8/16-bit per channel true color, and indexed color with palettes up to 256 entries — all with optional alpha transparency ranging from a single transparent color to a full per-pixel alpha channel with 256 or 65536 levels. PNG also stores gamma correction, ICC color profiles, text metadata, and suggested background color. One advantage is lossless compression with transparency — PNG preserves every pixel exactly while supporting smooth semi-transparent edges, making it the standard format for web graphics, UI elements, logos, screenshots, and any image where artifacts or color shifts are unacceptable. Universal support is another core strength: every web browser, operating system, image editor, and programming library handles PNG natively. The format has proven remarkably durable — after nearly three decades, PNG remains the default lossless web image format. While newer formats like WebP and AVIF offer better compression, PNG's combination of lossless quality, full transparency, and absolute ubiquity keeps it indispensable.

Why convert ARW to PNG?

ARW files are tied to RAW editors. PNG gives you lossless, transparent-capable images that work in any browser, editor, or design application.

What programs open PNG?

PNG is supported by all web browsers, Windows Photos, macOS Preview, Photoshop, GIMP, Paint.NET, and every modern image viewer.

Can I convert multiple ARW files to PNG at once?

Batch conversion is supported. Upload several ARW files simultaneously and each one converts to PNG independently in a single session.

Is registration required?

No account is needed for basic ARW to PNG conversions. Just open the converter, upload your Sony photo, and download the result.

Do I need to install software?

No installation required. The ARW to PNG converter runs entirely in your web browser — just upload, convert, and download the result.
