HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your ARW files
Drag in ARW photos from your Sony camera's card or your photo archive. You can add a whole shoot at once.
02
Convert to PNG
Start the conversion. Each RAW file is developed with LibRaw, an open-source RAW decoder used by many photo apps, and saved as PNG.
03
Download the PNG files
Download each PNG as it finishes or the whole set as one ZIP. Your original ARW files stay untouched on your device.
ARW
ARW is Sony's RAW format for Alpha cameras and premium compacts such as the RX100 and RX10 series.
PNG
PNG is a lossless image format with full transparency support, the usual choice for graphics, screenshots and editing copies.
FILE FORMATS
SOURCE
Sony's RAW format, written by every Alpha body from the early A-mount DSLRs to the A7, A9 and A1 mirrorless lines, and by the RX100 and RX10 compacts. Newer bodies offer uncompressed, lossless compressed and compressed ARW. Each version keeps the sensor data before Sony's Creative Style or Creative Look is applied.
TARGET
PNG stores every pixel exactly, so re-saving never degrades it. It supports full alpha transparency and 8 or 16 bits per channel, which makes it the standard for logos, UI graphics, screenshots and images that will be edited again. Photos as PNG are much larger than the same photo as JPG.
| Feature | ARW | PNG |
|---|---|---|
| Developed by | Sony | PNG Development Group (W3C) |
| File extension | .arw | .png |
| Compression | Uncompressed, lossless or lossy | Lossless |
| Transparency | No | Yes, full alpha |
| Color depth | 12 or 14-bit sensor data | 8 or 16-bit per channel |
| Best for | Editing with full exposure and color latitude | Graphics, screenshots, editing copies |
| Opens in browsers and phones | No, needs RAW software | Yes, everywhere |
USE CASES
When a lossless PNG suits the next step better than the RAW file.
Retouch portraits losslessly
Start skin and detail retouching from a PNG of an A7 III or A7R portrait, without JPEG artifacts in the way.
Cut out product shots
Remove backgrounds from ARW product photos in a PNG-friendly editor and keep clean edges.
Place photos in Figma or Canva
Design tools don't read ARW. A PNG drops into a layout and stays sharp.
Feed images to machine learning or analysis
Datasets and image analysis tools often want lossless input.
Keep a lossless developed master
Store a version that won't degrade when it's opened and saved again.
Produce scientific and technical photos
Measurement and documentation work often calls for lossless files from the camera RAW.
Create textures for 3D and games
Use PNG textures photographed on a Sony Alpha body.
Annotate and mark up screenshots of photos
Add arrows, labels and crops without stacking compression each time you save.
Work in editors that skip RAW
Paint.NET, many online editors and older software open PNG but not ARW.
Hand print designers a clean file
A lossless PNG avoids compression artifacts in large prints.
SUPPORTED FILES
Any ARW from a Sony Alpha body or RX compact can be developed to PNG.
A7, A7R, A7S, A9 and A6000-series files are supported. The newest bodies may need the DNG workaround below.
ARW files from Sony's RAW-capable compacts convert the same way.
All of Sony's ARW compression options upload as normal .arw files.
For sharing, use our ARW to JPG converter instead. PNG is meant for editing.
Upload many ARW files together. Each becomes a PNG, and the set downloads as one ZIP.
TROUBLESHOOTING
These explain most differences between the PNG and what you expected.
01
The camera screen shows a JPEG made with your Creative Look or Creative Style. The PNG is developed without it, so tweak color and contrast in any photo editor if you want that look back.
02
RAW files are developed with neutral contrast so no highlight or shadow detail is thrown away. Add contrast or brightness in an editor, or edit the ARW in a RAW editor if you need precise control.
03
Edits live in your editor's catalog or an .xmp sidecar file, not in the ARW. Export from that editor to get the edited version.
04
Each new camera model tweaks its RAW data, and decoders need an update to read it. If a ARW from a very recent body fails, convert it to DNG with the free Adobe DNG Converter and use our DNG to JPG tool.
05
Lossless photos are big. A 24 MP PNG is often 40 MB or more, and higher-resolution bodies produce larger files. Use JPG for sharing.
06
Sony corrects vignetting in its own JPEGs. Apply a lens profile in an editor if you want the same correction.
Lightroom, Capture One, darktable and your camera maker's software are built for editing RAW photos one at a time. dragdropdo is built for turning ARW files into PNG quickly, from any device.

MORE ARW TOOLS
ARW is Sony's raw image format, used by Alpha interchangeable-lens cameras and by compact cameras such as the RX100 series and the ZV-1. It stores the camera's unprocessed sensor data, which needs raw-processing software to edit or to convert into an ordinary photo.
