Raw.pics.io converts CR2 (Canon), NEF (Nikon), ARW (Sony), ORF (Olympus), PEF (Pentax), RAF (Fujifilm), and DNG files to JPEG or PNG inside your browser, without uploading the photos to a server. It is free for the first five conversions and requires no registration. You need a desktop computer, a current browser, and a stable internet connection — the page states it performs all manipulations in the browser, which is what keeps the files local.

Before you start

• A desktop browser (the site describes desktop use; phone behavior isn't documented).
• The RAW file on your local drive.
• No account needed for the first five conversions.

Step-by-step: view, then convert

1. Open the RAW file in the browser. Load Raw.pics.io and open your CR2/NEF/ARW/ORF/PEF/RAF/DNG file. The viewer renders the image so you can confirm it displays correctly before converting — useful because a file that won't preview usually won't convert either.
2. Check the preview. Confirm exposure, framing, and that the correct frame is showing. If the image is blank or garbled, stop here and see the troubleshooting section.
3. Choose the output format. Select JPEG or PNG. JPEG suits photos you'll share or print; PNG suits images where you want lossless output or transparency.
4. Set conversion options. The converter lets you resize, compress, and change the pixel size of the picture as you convert. Adjust dimensions and compression to match where the file is going.
5. Run the conversion. The tool processes the file in the browser and produces a downloadable JPEG or PNG.
6. Save the result. Download the converted file to your computer.

The site describes this as "a couple of steps," so expect a short flow rather than a multi-page wizard.

What "no upload" actually means here

The page states that instead of uploading your images to the internet, all manipulations happen right in your browser. In practice, that means the RAW data is read and decoded by code running on your own machine, so the photo itself isn't sent to the service's servers. This matters for client work, unreleased shots, or anything under an NDA. Note the limit of the claim: the page describes in-browser processing, not a fully offline app — you still load the site over the internet.

Free limit and registration

The page does not state what happens after the five free conversions, so treat the sixth conversion as an unknown until you check the site directly.

If the conversion fails

• File won't preview. Try a different browser, then re-check that the file isn't truncated or corrupted on the card or drive.
• Format not recognized. The site lists Canon, Nikon, Sony, Olympus, and Pentax RAW formats as directly supported, plus DNG. A RAW variant outside that list may not open.
• Conversion stalls. Since processing is local, a slow machine or a very large file can be the bottleneck rather than the connection.
• Output looks wrong. Re-check the resize and compression settings — changing pixel size during conversion alters the result.

When to use this instead of desktop software

Use the browser converter when you need a quick JPEG or PNG from a RAW file, you're on a machine where you can't install software, and the photo is sensitive enough that you'd rather not upload it. For batch work, precise color grading, or formats beyond the supported list, a desktop RAW editor remains the better fit.
