About ARW
ARW (Alpha RAW) is Sony's proprietary RAW image format used by Alpha mirrorless and DSLR cameras. Based on TIFF structure, ARW stores unprocessed 12-bit or 14-bit sensor data, preserving maximum dynamic range and color information for professional post-production. ARW files include embedded JPEG previews and comprehensive EXIF metadata including lens corrections and Real-time Eye AF data.

ARW is the standard RAW format for Sony's popular Alpha series including the A7, A7R, A7S, A9, A1, ZV-E1, and FX series cinema cameras. For sharing or web publishing, conversion to JPEG is necessary since RAW formats require specialized software like Adobe Lightroom, Capture One, or Sony's Imaging Edge Desktop application.
PNG (Portable Network Graphics) provides lossless compression with full alpha channel transparency, making it the go-to format for graphics, screenshots, and images requiring pixel-perfect fidelity. Created in 1996 as a patent-free GIF alternative, PNG uses DEFLATE compression and supports both indexed color (PNG-8) and truecolor with alpha (PNG-24/32). Files are 3-10× larger than equivalent JPEGs but preserve every pixel exactly.

PNG is universally supported and ideal for logos, UI elements, diagrams, and any content where transparency or lossless editing matters. For photographic content without transparency needs, JPEG typically offers better compression efficiency.
Frequently Asked Questions
What is an ARW file?
ARW (Alpha RAW) is Sony's proprietary RAW image format storing 12-14 bit unprocessed sensor data. Introduced with the first Alpha DSLRs in 2006, ARW captures maximum dynamic range (up to 15 stops on modern sensors) for post-processing flexibility.
ARW files typically range from 25-60 MB depending on resolution. The A7R V produces files up to 120 MB due to its 61MP sensor.
Which Sony cameras are supported?
All Sony Alpha cameras producing ARW files are supported:
- Full-Frame Mirrorless: A7 IV, A7R V, A7S III, A7C II, A9 III, A1, FX3, FX30, ZV-E1
- APS-C Mirrorless: A6700, A6600, A6400, A6100, ZV-E10, ZV-E10 II
- Legacy SLT/DSLR: A99 II, A77 II, A700 (SR2/SRF formats also supported)
Why choose PNG over JPG for ARW conversion?
PNG provides lossless compression while JPG uses lossy compression. Choose PNG when:
- Archival quality: No compression artifacts, ever
- Further editing: No quality loss from repeated saves
- 16-bit color: PNG preserves more color depth than 8-bit JPG
- Transparency: PNG supports alpha channels if needed
Trade-off: PNG files are 2-4x larger than equivalent JPGs.
For smaller files optimized for web sharing, use our ARW to JPG converter.
Is quality preserved when converting ARW to PNG?
Yes, PNG conversion is lossless. Unlike JPG, PNG uses lossless compression that preserves all pixel data exactly. The conversion process:
- Demosaics the RAW sensor data via LibRaw
- Applies auto white balance with camera hints
- Converts to sRGB color space
- Compresses with PNG's lossless DEFLATE algorithm
The resulting PNG can be edited repeatedly without quality degradation.
What software can edit ARW files?
ARW files are supported by most professional photo editors:
- Sony Imaging Edge Desktop (free) — Sony's native RAW editor
- Adobe Lightroom/Camera Raw — Full support via Adobe Camera Raw
- Capture One — Excellent Sony color science
- DxO PhotoLab — Advanced noise reduction for high-ISO ARW
- Darktable (free, open-source) — Full ARW support
Converting to PNG creates a universally compatible format for sharing or archiving without requiring RAW-capable software.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Guest/Free | 100 MB | 50 files | 3 at once |
| Pro | 1024 MB | 1000 files | 6 at once |
Note: File size limits are specific to this converter. Batch and parallel processing limits apply to all images converters site-wide. See all converter limits →
How are credits calculated for this conversion?
Cost: 1 credit per 5 MB
How it works:
- Files up to 5 MB: 1 credit
- 6-10 MB: 2 credits
- 11-15 MB: 3 credits
- 16-20 MB: 4 credits
Example: A 5 MB photo = 1 credit. A 95 MB photo = 19 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Guest | 100 credits/day | — |
| Free | 100 credits/day | — |
| Pro | — | 12,000 credits/month |
Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) reset on your billing cycle date.
Note: With 1 credit per 5 MB, ARW files under 5 MB cost 1 credit each. Pro users can convert 12,000 ARW files per month.
