ARW to AVIF Converter

Convert ARW to AVIF: What This Tutorial Covers

This walks a Sony shooter through turning a .arw raw file into a small, web-ready AVIF — when it's the right move, the one setting that matters, and the gotchas that trip people up. The short version: convert a copy to AVIF for the web and keep the original .arw as your editable master, because the conversion bakes in the render and the raw editing latitude does not survive it.

How to Convert ARW to AVIF

1. Upload Your ARW File: Drag and drop your Sony .arw onto the page or click "+ Add Files" to browse. You can queue several Alpha raw frames at once — straight off an α7, α6000-series, or older DSLR-A body.
2. Pick a Quality Preset: Open Advanced Options and set "Quality Preset" — "Very High (Recommended)" is the default and a good balance of detail and size; step down to "High" or "Medium" for a smaller file.
3. Set Image Resolution (Optional): Leave "Image resolution" on "Keep original," or pick a preset, a resolution percentage, or an exact width/height to downscale for the web.
4. Convert and Download: Click "Convert" and download your AVIF. No sign-up, no watermark.

Walk-through: Picking the Right Quality and Size

The raw is rendered to ordinary pixels and then AVIF-encoded, so your "Quality Preset" choice is the single biggest lever on the final look and weight. AVIF degrades gently — at lower quality it tends to soften and smear fine texture rather than throw up the blocky squares JPEG produces — which means you can push the preset down further than you'd dare with JPEG before anyone notices.

• Want a near-archival web copy? Keep "Quality Preset" on "Very High" and "Image resolution" on "Keep original." This is the largest AVIF you'll make here, but still far smaller than the source raw.
• Optimizing a page for load speed? Drop to "High" or "Medium" and downscale "Image resolution" to the largest size you actually display (for example a 2048px-wide preset for a full-bleed hero) — serving a 6000px image to a 1600px layout wastes bytes.
• Need a specific ceiling? Use the "Specific file size" control to cap the output, and the encoder works backward from your target.
• Watching encode time? AVIF is slower to encode than JPEG by design; a big batch of full-resolution raws will take a while. That cost is paid once, on our servers, not on every page view.

Common Errors and How to Fix Them

• "The colors or exposure look off versus my edit." A camera's Creative Look or picture profile is a Sony in-body rendering instruction, and third-party raw renderers don't always reproduce it exactly. Apply your look in a raw editor and export a finished image first if color accuracy matters.
• "The AVIF won't open on an older device or in an old app." AVIF is recent. Roughly 93% of browser users can view it, but some older desktop viewers and editors can't. For an unknown recipient, send ARW to JPG instead — it opens everywhere.
• "It looks soft compared to the raw." That's usually too low a "Quality Preset" or too much downscaling. Step the preset up and keep "Image resolution" closer to the original.
• "I uploaded an .arw and expected to keep editing it." A converted AVIF is a finished picture, not raw data — there's no editing latitude left in it. Keep the .arw and convert copies as needed.
• "My file is too big to send quickly." Sony raws often run tens of megabytes each, so the practical limit here is upload size and time, not the conversion itself. A wired connection or smaller batches help.

When This Doesn't Work

AVIF is a delivery format, so it's the wrong target whenever you still need the raw's headroom or universal reach. If you plan to recover highlights, reset white balance, or push exposure, don't convert yet — keep the .arw master and edit that. If you need a print-ready or lossless-editing file, render to ARW to TIFF for a high-bit-depth, lossless output instead. And if the file has to open on anything and everything — email, older phones, any viewer — ARW to JPG is the safe, universal choice. There's no motion or hidden layers to extract from an ARW; it's a single still frame, so this page exists to render and compress that one frame, not to recover anything that was never in the file.

Frequently Asked Questions

Do I lose the RAW editing latitude when I convert ARW to AVIF?

Yes. An ARW stores unprocessed sensor data — typically 12-bit on early Sony Alpha bodies and 14-bit on most modern α models — which is why you can recover highlights and shadows and reset white balance long after the shot. To write an AVIF, the converter demosaics that data and bakes in the current white balance, exposure, and tone. Once it's an AVIF you're editing a finished image, not the raw. Adjust in a raw editor first if you want control, then convert the result, and keep the .arw as your master.

Are ARW and AVIF the same quality after converting?

Not in the sense the question usually means. ARW holds unprocessed sensor data with wide editing latitude; AVIF holds a rendered, compressed picture. The visible result can look excellent — often indistinguishable from the raw at normal viewing sizes — but the editing headroom is gone. For a faithful, web-ready copy AVIF is great; for anything you may re-edit, keep the original .arw.

Why convert a Sony RAW to AVIF instead of JPEG?

Size at a given quality. At similar perceived quality, AVIF files are typically about 30-50% smaller than JPEG, and AVIF degrades more gracefully — its artifacts look like soft blur rather than JPEG's blocky edges, especially across skies, gradients, and fine texture. The trade-offs are encoding speed and reach: AVIF takes longer to encode, and a small share of older browsers can't display it. If universal compatibility matters more than file size, ARW to JPG is the safer choice.

Does this converter output HDR or 10-bit AVIF?

The AVIF format itself supports 10- and 12-bit color and HDR, which is one of its advantages over JPEG. This converter targets a standard, broadly compatible AVIF suitable for web delivery rather than an HDR-graded master, so treat the output as a standard-dynamic-range delivery copy. If you specifically need a wide-gamut, high-bit-depth file for editing or print, render the raw to ARW to TIFF instead, which preserves high bit depth losslessly.

Which browsers and apps can open an AVIF file?

In browsers, AVIF is supported by Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+ — about 93% of users worldwide can view it natively, per caniuse. Desktop support is more uneven: recent Windows (with the AV1 Video Extension), macOS Ventura and later, and tools like GIMP and current Photoshop can open AVIF, but many older viewers and some editors still can't. If you're handing the file to someone on an unknown setup, JPEG remains the safest bet.

How are my files handled during conversion?

In our testing, a 24-megapixel ARW rendered to AVIF at the "Very High" preset produced a file a fraction of the original raw's size while staying visually sharp at normal viewing sizes. Your file is uploaded over an encrypted connection, rendered and encoded into AVIF on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The main practical limit on a big upload is its size and the time it takes to send, since Sony raws often run tens of megabytes each, not your device. For privacy-sensitive originals, keep the .arw locally and convert only the copies you need.
