ARW is Sony's Alpha RAW format — the unprocessed sensor data straight off your camera, which most browsers and editors can't display. This tool demosaics that RAW and renders it to a standard PNG, so you get a sharp, universally viewable image with lossless compression and no JPEG blocking artifacts. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
How to Convert ARW to PNG
- Upload Your ARW File: Drag and drop your
.arwfiles onto the page or click "Add Files." You can queue several at once and they convert with the same settings. - Pick a Quality Preset: Open Advanced Options and set the Quality Preset (default "Very High"). Because PNG is lossless, this governs how the RAW is rendered to RGB rather than introducing compression artifacts.
- Resize if Needed: Sony RAW files are high resolution, so a full-size PNG is large. Use Resolution Percentage or a preset to scale down, or keep the original dimensions.
- Convert and Download: Click Convert and download your PNG. It opens in any browser, OS image viewer, or editor — no sign-up, no watermark.
ARW vs PNG vs JPG: Which Output Fits
| ARW (Sony RAW) | PNG | JPG | |
|---|---|---|---|
| Compression | Lossless RAW | Lossless | Lossy |
| Color depth | 12 or 14-bit per channel | 8-bit per channel (this tool) | 8-bit per channel |
| Editing latitude | Full (white balance, highlight recovery) | Baked in | Baked in |
| Transparency | No | Yes (alpha channel) | No |
| Typical file size | Largest | Large | Smallest |
| Opens everywhere | No (needs RAW support) | Yes | Yes |
For a smaller everyday copy, use the ARW to JPG converter instead. If you need 16-bit precision or a print-oriented master, convert ARW to TIFF, which preserves higher bit depth than PNG does here.
Frequently Asked Questions
Will I lose image quality converting ARW to PNG?
The PNG itself is lossless, so it carries the rendered image with no compression artifacts — unlike JPG. What you do lose is RAW editing latitude: a Sony ARW holds 12 or 14-bit sensor data, and rendering it to an 8-bit PNG bakes in the white balance, exposure, and tone, so you can't recover blown highlights or re-set white balance afterward the way you could in a RAW editor.
Does this PNG output keep the 14-bit depth of my Sony RAW?
No. The PNG this tool produces is 8-bit per channel, which is standard for PNG and plenty for viewing and sharing. If you specifically need to preserve the wider bit depth your camera captured, convert ARW to TIFF instead — TIFF can store 16-bit per channel and is the better choice for a high-precision master.
Why won't my ARW file open or preview normally?
ARW is RAW sensor data based on the TIFF/EP container with Sony's proprietary Makernote fields, not a finished image, so browsers and many viewers can't render it directly. Converting to PNG demosaics the Bayer-pattern sensor data into normal RGB pixels that any program can display.
Why is my PNG so much larger than the original JPG would be?
PNG uses lossless compression, so a detailed photo keeps every pixel exactly and the file stays large — often several megabytes for a full-resolution Sony image. In our testing, a 24-megapixel ARW rendered to a full-size PNG typically lands in the tens of megabytes. To shrink it, lower the Resolution Percentage during conversion or run the result through the Image Compressor.
Are my uploaded Sony RAW files kept private?
Yes. Your ARW files are sent over an encrypted connection, converted on our servers, and deleted automatically a few hours after the job finishes. There's no sign-up, the output carries no watermark, and files are never shared or made public.
