Edit ARW Files Online
Open Sony Alpha RAW (ARW) files from Sony cameras right in your browser — decode, color grade and export JPEG in minutes. Free, no upload, no software to install.
What is a ARW file?
ARW is the RAW format produced by Sony A7 IV, A7R V, A6700, A7C II, ZV-E1 and other Alpha / ZV cameras. ARW files store 14-bit sensor data with far more highlight and shadow detail than the JPEGs your camera saves alongside them.
Because ARWis a RAW format, most image viewers and web tools can't open it. OpticRaw decodes it with LibRaw — the same engine used by professional desktop software — compiled to WebAssembly so it runs locally in your browser.
How to edit a ARW file online
- Open OpticRaw and drag your ARW file into the window.
- Wait a few seconds while the RAW is decoded (your camera's white balance is applied as the starting point).
- Edit with Lightroom-style tools: exposure, tone curve, HSL color mixer, color grading wheels, masking brush, crop & straighten.
- Click Export to save a full-resolution JPEG or PNG.
Why edit ARW instead of JPEG?
RAW keeps the full sensor data: highlights you can pull back, shadows you can lift cleanly, and white balance you can change after the fact. Editing the ARW file gives dramatically better results than editing the camera JPEG — especially for exposure mistakes and tricky light.

Frequently asked questions
Can I open ARW files online for free?
Yes. OpticRaw decodes ARW files directly in your browser using LibRaw (WebAssembly) — free, no watermark, no account.
Is my ARW file uploaded to a server?
No. The file is decoded and edited entirely on your device. It never leaves your computer.
How do I convert ARW to JPEG?
Open the ARW file, make any adjustments you want (or none), then click Export and choose JPEG. You get a full-resolution JPEG in seconds.
Do I need Lightroom or Photoshop to edit ARW?
No. This editor gives you Lightroom-style tools — tone curve, HSL mixer, color grading wheels, masking, crop — right in the browser.
Does editing change my original ARW file?
Never. Editing is non-destructive: the original RAW file stays untouched and you export a separate JPEG or PNG.
