Frequently asked questions

How do I convert X3F to JPG?: Upload your X3F file above and it is converted to JPG automatically. Then click Download. No software to install — it runs in your browser and on our server.
How do I open a X3F file?: X3F files often won't open in an ordinary photo viewer without specialist software. The quickest way to open one is to convert X3F to JPG here — upload your file and download a standard JPG that opens on any phone, computer or browser.
Can I use this as a X3F file viewer?: Yes — it doubles as a free online X3F viewer. Upload your file and the converted JPG is displayed right in your browser, so you can see the image without installing a X3F viewer or codec pack. Download the JPG if you want to keep it.
What is a X3F file?: X3F is Sigma's camera RAW format — the unprocessed sensor data your camera saves for maximum editing latitude. Because it isn't a standard image, most apps can't open it directly, so converting to JPG gives you a shareable picture.
Is the X3F to JPG converter free?: Yes — it is free, with no signup. Premium adds batch conversion (many files into one ZIP) and larger uploads.
Can I convert X3F to JPG without Photoshop or Lightroom?: Yes. Your X3F file is decoded with professional camera-RAW processing on our secure servers, so you don't need Photoshop or Lightroom — or any other software — installed. Upload the file, then download the finished JPG.
Will I lose quality converting X3F to JPG?: X3F is processed at full resolution. JPG output uses a high-quality default you can adjust. For archival work keep your original RAW too.
