ARW to JFIF Converter

How to Convert ARW to JFIF Online

1. Upload Your ARW Files: Drag and drop or click "+ Add Files" to select Sony Alpha RAW photos (.arw, also .srf and .sr2 from older Sony bodies). Batch is supported — drop in an entire shoot folder.
2. Pick a Quality Preset: Default is "Very High (Recommended)", which preserves most of the detail captured by Sony's 14-bit sensor. Drop to "High" for smaller web-ready files, or switch to "Specific file size" to target an exact KB/MB cap (Smart Scaling adjusts dimensions to hit it). For fine-grained control, use the "Image Quality (%)" slider (1–100, default 80).
3. Set Resolution and DPI (Optional): Keep original, scale by percentage (1–100%), pick a preset (4320p down to 144p), or enter a custom Width × Height. DPI defaults to 300 (print-ready); set 72 / 96 for screen-only output.
4. Convert and Download: Click Convert. ARW decoding and JFIF encoding run in your browser session — no upload to a third-party server, no sign-up, no watermark. Files download individually or as a ZIP.

Why Convert ARW to JFIF?

ARW is Sony's proprietary RAW format used by every Sony Alpha mirrorless body (a7, a7R, a7S, a9, a1, a6000-series, ZV-E series) and the RX cyber-shot line. A single ARW preserves the unprocessed sensor reading at 14-bit depth, so a Sony a7R V file (60.2 MP) commonly lands at 60–70 MB uncompressed, and even a 24 MP a7 III shot is 24–48 MB. JFIF (JPEG File Interchange Format) is the same JPEG-compressed bitstream you already know, wrapped in the standardized JFIF APP0 segment that every browser, OS, photo viewer, and CMS understands.

• Match what Edge and Windows already produce — Microsoft Edge on Windows 10 (since version 1909, released November 12, 2019) saves "Save image as…" downloads with the .jfif extension by default. Converting your ARW shoot directly to JFIF means filenames stay consistent with the rest of your image library.
• Drop ARW file size by 95%+ — A 60 MB ARW typically compresses to 2–8 MB at "Very High" quality and well under 1 MB at "High". That fits Gmail's 25 MB attachment cap, Discord's free 10 MB upload (raised to 25 MB on Nitro), and any CMS with a per-image limit.
• Universal compatibility — Browsers, iOS, Android, Photoshop, Lightroom, Word, PowerPoint, web galleries, and print labs all read .jfif as JPEG. ARW files cannot be opened by most of these without Sony's free Imaging Edge Desktop, Adobe Camera Raw, or a similar RAW-aware converter.
• Faster culling and previews — A folder of JFIFs scrolls instantly in Windows Photos, macOS Preview, and any web gallery. ARW thumbnails rebuild slowly and many viewers refuse to render them at all.
• Web publishing without a CMS plugin — WordPress, Squarespace, and Shopify all accept JFIF/JPEG natively. ARW uploads either reject outright or silently fail.
• One-shot delivery to clients — Send a finished JFIF gallery instead of asking clients to install RAW software. Keep your ARW originals for re-edits.

ARW vs JFIF — Format Comparison

JFIF vs JPG vs JPEG — Are They the Same?

Yes, in practice, with one technical wrinkle. The JPEG standard (ITU-T T.81 / ISO/IEC 10918-1) defines compression but doesn't specify a file container. JFIF (T.871, standardized 2011) adds the mandatory APP0 marker that records resolution, aspect ratio, and YCbCr color space. Almost every "JPG" file you've ever seen is technically a JFIF wrapper around a JPEG bitstream.

All four open identically in browsers, Photoshop, GIMP, and image viewers. The only practical difference is which extension your operating system or upload form expects. If a service rejects .jfif, rename to .jpg — the bytes are identical.

Frequently Asked Questions

Why does Microsoft Edge save my downloads as .jfif instead of .jpg?

Since the November 2019 update (Windows 10 version 1909), the registry key HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/jpeg defaults to .jfif as the file extension for the image/jpeg MIME type. Edge, Chrome, and Vivaldi on affected systems all honor it. The contents are the same JPEG bytes — the extension is the only change. You can either edit the registry back to .jpg (Windows updates may revert it) or convert .jfif to .jpg with JFIF to JPG.

Which Sony cameras produce ARW files?

Every Sony Alpha mirrorless body since 2010 — the a7 / a7R / a7S / a7C / a9 / a1 / ZV-E series, plus the APS-C a6000 / a6300 / a6400 / a6500 / a6600 / a6700 lineup. Sony RX1, RX10, and RX100 cyber-shot compacts also write ARW. Older Sony DSLR-A and Konica Minolta-derived bodies wrote earlier .srf and .sr2 RAW files; xconvert accepts those alongside .arw on this page.

What quality should I pick for sharing online?

"Very High (Recommended)" gives the closest match to your ARW exposure, usually 4–10 MB. For social posts, web galleries, or anything compressed by the platform anyway (Instagram, Facebook), drop to "High" or set "Image Quality" to 80–85% for files of 1–3 MB. For email or 25 MB attachment caps, use "Specific file size" with a target of 5–10 MB and let Smart Scaling pick dimensions.

Will I lose RAW editing flexibility after converting?

Yes — conversion bakes in white balance, exposure, contrast, and the 14-bit-to-8-bit color depth reduction. Highlight and shadow recovery latitude that ARW gives you (typically 4–6 stops) is gone in the JFIF. Do your color and exposure editing in Sony's free Imaging Edge Desktop, Lightroom, Capture One, or darktable first, export to ARW or DNG with the edits applied, and then convert. Or keep your ARW originals as a master archive and use the JFIF only for delivery.

Should I convert to JFIF or JPG?

Functionally identical — same data, same compression, same file size. Pick .jfif if your downstream system (a Windows Photos library, an internal CMS, an upload form) explicitly expects it. Otherwise ARW to JPG gives the more universally recognized .jpg extension. Some upload forms reject .jfif by extension check even though the bytes are valid JPEG.

Will EXIF metadata (camera, lens, ISO, GPS) survive the conversion?

Yes — EXIF tags written by your Sony body (camera model, lens, ISO, shutter, aperture, GPS if enabled) are preserved in the JFIF output. If you want to strip metadata before sharing publicly (e.g. to remove GPS coordinates), use the metadata-removal option in advanced settings.

Can I batch-convert a full shoot?

Yes — drop in an entire folder. Each ARW decodes in parallel within your browser session, with one common quality / resolution / DPI setting applied across the batch. Output downloads individually or as a single ZIP. Practical limit is browser memory; batches of 50–200 files typically work fine on a desktop with 16 GB RAM.

Does xconvert upload my ARW files to a server?

No — ARW decoding and JFIF encoding both run client-side in your browser session. The originals never leave your machine, which matters for client work, NDA shoots, and personal photos. There's no account requirement and no watermark.

What's the difference between ARW and DNG?

ARW is Sony-proprietary; DNG is Adobe's open-standard RAW container. Adobe DNG Converter can wrap an ARW into DNG for long-term archival (Sony's ARW spec changes per camera model and may not be readable in 20 years; DNG is published). ARW → JFIF here is the delivery path; ARW → DNG is the archival path. If you want JPEG-from-DNG instead, Lightroom or Capture One handles that natively.

Why is my JFIF still 8 MB? Can I shrink it more?

"Very High" preserves nearly all visible detail, which keeps files large. Switch to "High" or 70–80% Image Quality for 2–4 MB. Resize to 2048 px on the long edge (a "1080p+" preset) to roughly halve the file size again. For aggressive optimization after conversion, run the JFIF through Compress JFIF — same in-browser pipeline, more aggressive size targets.
