Quick Answer: How to Convert ARW to PNG
ARW is Sony's Alpha Raw format. Converting it to PNG runs the full raw-development pipeline — demosaicing, white balance, color profile — and bakes those settings into the output, the same way your camera's JPEG engine would. Run it free at practicalwebtools.com/convert/image/arw-to-png: drop in your ARW, adjust settings if you like, and download the PNG — no signup, no upload, everything stays on your device.

Frequently Asked Questions
Will converting ARW to PNG lose quality?
It depends on the formats: ARW is uncompressed, lossless-compressed, or lossy-compressed raw and PNG is lossless DEFLATE — screenshots and graphics compress extremely well. Any step from a lossless source into PNG keeps everything; any lossy step re-encodes and discards some data.
Are my files uploaded anywhere during ARW → PNG conversion?
No. This converter runs on WebAssembly inside your browser — your ARW file is read from disk, processed by your device's CPU, and the PNG is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
Why does my PNG look different from the camera preview?
ARW is Sony's Alpha Raw format. A raw file isn't an image yet — the converter applies a development pipeline (demosaicing, white balance, tone curve) to produce the PNG, and different settings yield different-looking results from the same raw file, exactly like a darkroom.
Do I need to install anything to convert ARW to PNG?
No installation. The converter is a web page — open it in any modern browser on Windows, macOS, Linux, iOS, or Android. ARW decoding and PNG encoding both run via WebAssembly at native-adjacent speed.
Does the converter keep metadata (title, artist, cover art)?
Where the PNG container supports it, standard tags are carried across. PNG's "interlaced" option (Adam7) enables progressive loading at 1/64 resolution — obsolete for most uses today, but the option lives on in every save dialog
