X3F (Sigma/Foveon RAW) is a RAW image file captured directly by Sigma cameras. Unlike JPG, a X3F file stores unprocessed sensor data — preserving maximum dynamic range, colour detail, and editing flexibility for professional photography workflows in Lightroom, Capture One, and Photoshop.
RAW files record exactly what the camera sensor captures before any in-camera processing takes place. White balance, sharpening, noise reduction, and tone curves are stored as adjustable metadata rather than baked into pixels. This means a X3F file can be colour-corrected and exposed entirely non-destructively, with far more shadow and highlight recovery headroom than a JPEG can offer. The trade-off is file size — X3F files are typically 15–30 MB each, compared to 2–5 MB for an equivalent quality JPEG.
RAW files like X3F are ideal for editing but poor for sharing. JPG is recognised by every phone, PC, printer, and website. Converting X3F to JPG makes your photos email-ready, social-media compatible, and easy to send to clients who do not use RAW workflows — while keeping file sizes manageable for uploads and storage.
A single X3F file can weigh 15–30 MB. Batch-sending 50 edited photos would mean hundreds of megabytes of transfer data. Converting to JPG at 90–95% quality is visually indistinguishable from the RAW original for both web and print, while reducing file sizes by 80–90%. Your clients get beautiful images they can open instantly; you save storage, upload time, and shared drive quota.
Send edited X3F photos as JPG proofs clients can open on any device without RAW software.
Share camera originals from X3F to JPG for Instagram, WhatsApp, and messaging apps.
Many print services prefer JPG. Convert X3F before uploading to online print labs.
Publish photography online with fast-loading JPG exports from your X3F archives.
Make all exposure corrections, colour grades, and retouches in Lightroom or Capture One before converting X3F to JPG. JPG is a delivery format — re-editing a JPEG introduces compounding quality loss.
For client proofs and social media, 90–92% JPG quality is visually identical to the RAW original. Drop to 75–85% only for web thumbnails where download speed matters more than pixel-perfect detail.
Never delete original X3F files after converting. RAW files are your negatives — storage is cheap, and you may need to reprocess them with better tools or different styles in future.
SnapConvert processes up to 20 X3F files simultaneously in your browser. Drop a whole shoot at once, convert, and download as a single ZIP — no per-file wait time.
Drop X3F images into the converter or click Choose Files to browse your computer or phone.
Keep the default 92% for excellent results, or adjust the slider to balance file size and visual quality for web or print.
Click Convert and download your JPEG files instantly — individually or as a ZIP archive for batch jobs.
