About this app

RAW to JPG Converter & Viewer turns the RAW photos from your camera into full-size JPG files on your phone. Offline, with no upload and no account. Shot RAW on a Canon, Nikon, Sony or Fujifilm camera? Copy the files to your phone, convert NEF, CR2, CR3, ARW, RAF or DNG to JPG, and share your pictures the same day.

Every file is checked first, so you know what is really inside before you convert, and when a file cannot be converted the app says so and tells you why. After converting, it works as a RAW viewer: see each photo full screen and zoom in to check focus before you save. You never get a grey rectangle or a tiny thumbnail passed off as your photo.

TWO HONEST ROUTES TO A FULL-SIZE JPEG
1. Copied exactly. Most cameras store a finished, full-size JPEG inside every RAW file. When it is there, the app copies it out untouched: the same pixels and your camera's own colours, with no re-compression.
2. Developed on your phone. Phone DNG files, and some older Canon CR2 files, hold only sensor data. For those, the app develops the RAW image itself (demosaicing, the file's own colour calibration, white balance, highlight handling) and writes a real full-resolution JPG.

HOW IT WORKS
1. Pick RAW files from your phone, an SD card or a USB card reader.
2. Every file is sorted: full size, developed on the phone, thumbnail only, or not convertible, always with the reason.
3. Tap Convert. The date taken, camera model and orientation are kept in the JPG.
4. Check each photo full screen with pinch-to-zoom, then save it to your gallery or share it.

MADE FOR PHOTOGRAPHERS ON THE MOVE
• Batch RAW to JPG: pick many files at once and convert them in one go
• Works offline: on a trip, on a plane, at the shoot
• RAW file viewer with full-screen zoom to check sharpness
• Converted photos go to Pictures / RAW to JPG in your gallery
• English and Arabic

PRIVATE BY DESIGN
Your photos never leave the phone. No upload, no server, no account.

PRICING, PLAINLY
Opening, checking, converting and previewing your photos cost nothing. Saving or sharing the converted JPGs needs an unlock: either a one-time purchase that covers every photo you convert, or a monthly plan you can cancel at any time in Google Play. The first time you open the unlock screen, the one-time unlock has a launch price for one hour.

WHAT IT IS NOT
It is not a photo editor and not a camera app. It does one job, RAW to JPEG conversion, and tells you the truth about every file.

Camera and phone brand names are used only to describe file formats. This app is not affiliated with any of them.

• A clear message when the phone is too full to hold a file.
