Why ARW files need care

Sony stores a full-size JPEG preview inside most ARW files next to the raw data. That is why so many tools show you a picture almost instantly and then produce something different when you actually convert. This page does not take that shortcut: the frame is decoded from the sensor data, so the output matches the file rather than the preview.

Sony also changes compression between camera generations, and some bodies record lossless-compressed raw that older decoders reject outright. If your file is one of those, the row says so - a failure you can see beats a JPG that quietly looks wrong.

Nothing is uploaded. The RAW file is decoded in this tab by LibRaw compiled to WebAssembly — no upload step, no server copy, no account.

Questions about converting ARW to JPG

Why not just use the embedded preview?

Because the preview is a separate, smaller JPEG the camera generated. Using it would hand you a lower-resolution picture than the file actually contains. Decoding the sensor data takes longer and gives you the real frame.

Does it handle lossless-compressed ARW?

Usually, through LibRaw. Sony has introduced new compression with recent bodies, and a decoder that predates a camera cannot know its format. Failures are reported per file rather than hidden.

How long does a 61 megapixel file take?

Longer than the 26 megapixel frame we measured at two to three seconds - roughly in proportion to the pixel count. Expect several times that on a laptop, and more on a phone, where memory is the binding constraint rather than processor speed.

Do you keep a copy of my file?

No. There is no upload step and no server behind this page. The file is read into this tab, decoded here, and handed back as a download link that never leaves your machine.
