How to Convert ARW to PPM — Quick & Free
Fast, instant ARW (SONY) to PPM conversion. No signup required. Just drop your .arw file and get .ppm in seconds.
Batch Settings
HDR data will be tone-mapped
Your ARW file may contain HDR (High Dynamic Range) data. PPM only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Some metadata may not survive
Your ARW file may contain EXIF, MakerNote, XMP metadata. PPM has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About ARW (SONY) to PPM Conversion
Short answer: yes, you can convert ARW to PPM online for free, and some quality differences may occur depending on the format types. Just upload your .arw file to CocoConvert, pick PPM as the output, and click Convert. The whole process takes seconds.
Now for the details. ARW is Sony's RAW photo format preserving the full dynamic range captured by the sensor. PPM (Portable Pixmap) is a simple uncompressed image format used in scientific imaging. Converting between these two formats lets you convert between formats quickly.
Full Name: ARW uses Sony Alpha RAW, while PPM uses Portable Pixmap. Compression: ARW uses Lossless, while PPM uses None (uncompressed). Transparency: ARW uses No, while PPM uses No.
Your ARW file is decoded and re-encoded as PPM. Your ARW file may contain HDR (High Dynamic Range) data. PPM only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Common misconception: ""PPM will be smaller than my ARW file"" — in reality, ppm uses no compression, so the output file is often larger than a lossy arw. if you need a small file, ppm may not be the right choice.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert ARW (SONY) to PPM
Your ARW image is decoded into raw pixel data, then re-encoded as PPM. No quality loss — pixel data is preserved exactly.
Your ARW file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where PPM supports it
The PPM file is saved and ready for download

Common Mistakes When Converting ARW (SONY) to PPM
"PPM will be smaller than my ARW file"
PPM uses no compression, so the output file is often larger than a lossy ARW. If you need a small file, PPM may not be the right choice.
Frequently Asked Questions
Is ARW to PPM conversion free?
Yes. CocoConvert offers free ARW to PPM conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is ARW to PPM conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded ARW file and the converted PPM file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting ARW to PPM lose quality?
Your ARW file may contain HDR (High Dynamic Range) data. PPM only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Can I convert PPM back to ARW?
Yes, CocoConvert supports PPM to ARW conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
