RAW Batch — The complete guide to batch RAW conversion.

Version 4.1.0 for macOS · Version 2.0.0 for iPhone & iPad — develop and convert your camera's RAW files with confidence.

1. Overview

RAW Batch turns your camera's RAW files into polished, ready-to-share images — in seconds. It reads the most popular camera RAW formats (CR2, CR3, NEF, ARW, DNG, RAF, ORF, RW2, PEF) plus common formats like JPEG, PNG, TIFF, HEIC, BMP, GIF, and JPEG-2000, and exports to JPEG, PNG, TIFF, HEIC, JPEG-2000, or BMP.

Everything runs locally on your Mac, iPhone, or iPad — no cloud upload, no accounts, no tracking.

The free plan includes up to 5 conversions per day with no subscription required. Upgrade to Pro for unlimited conversions.

2. Quick Start

macOS

1. Add files — drag RAW files anywhere onto the window, or use Import Files… and Import from Photos….
2. Choose an output folder — pick where the converted files will be saved in the bottom toolbar.
3. Tune (optional) — adjust white balance, highlights, and brightness with a live preview.
4. Click Convert — watch progress as your batch converts.
5. Find your files — the converted images appear in the output folder you chose.

iPhone & iPad

1. Add files — tap Import Files… to pick RAW files from the Files app, or Import from Photos… to pull them from your photo library.
2. Open a file — tap it in the batch list to see its settings. On iPad the list and the settings sit side by side.
3. Tune (optional) — adjust white balance, highlights, brightness, format, and size with a live preview.
4. Tap Convert — progress is shown for every file in the batch.
5. Share the results — use Share on a file, or Share All, to send the converted images to Photos, Files, AirDrop, or another app.

That's it — your first batch in five steps.

3. Adding Files

macOS

• Drag & drop — drag files from Finder anywhere onto the window. The drop zone highlights while you drag.
• Import Files… — open a file picker and select RAW or image files from your file system (also available from the File menu and the + Add button in the file list).
• Import from Photos… — import photos straight from the Photos app using the system picker.

iPhone & iPad

• Import Files… — pick RAW or image files from iCloud Drive, On My iPhone, or any other provider in the Files app.
• Import from Photos… — choose photos from your library with the system photo picker.
• Open in RAW Batch — in Files or another app, share a RAW file and choose RAW Batch to add it to the batch. All imports are copies, so your originals are never modified.

Unsupported files are ignored, and a note shows how many were skipped. Each supported file appears in the batch list.

4. The File List

Every added file appears in the list with its thumbnail, format, size, and resolution, so you can see at a glance what's queued up.

• Select a file to edit its settings — in the right-hand panel on the Mac, or in the detail view on iPhone and iPad. On iPad the list and the settings column are shown together.
• Status — each file shows whether it is queued, converting, succeeded, or failed.
• Remove files you don't need before starting the batch. On the Mac, Delete removes the selected items; Delete All Files clears the whole list.

5. RAW Development

For RAW files, the settings panel includes a RAW Settings section:

• White Balance — Camera uses the white balance recorded by your camera; Auto lets the app estimate it.
• Highlight Mode — recovers blown-out highlights. Choose Clip, Recover, Blend, or Rebuild.
• Brightness — a slider from 0.50 to 1.50 to fine-tune overall exposure.

Changes update the preview live, so you can tune until it looks right before converting. On iPhone and iPad there's a filter to show a single file's preview in full screen while you adjust it.

6. Output Settings

The output section controls the format and quality of the converted files:

7. Rotation & Scaling

The Transform section applies to all file types:

• Rotation — Auto, 90°, 180°, or 270°.
• Scale Mode — Original Size, Percentage, Fit to Width, Fit to Height, Fit to Long Edge, Fit to Short Edge, Fit Within presets (3840×2160, 1920×1080, 1280×720, 1600×1200, 1024×768, 800×600), or Fit Within (Custom).

Percentage scaling can enlarge, but output is capped at 16384 px on the longest edge. The Fit modes are downscale-only and always preserve the aspect ratio.

8. Batch Conversion

Add as many files as you like and convert them all at once:

1. Add all the files you want to convert.
2. Set a common output format, and on the Mac an output folder as well.
3. Click Convert (enabled whenever there are pending files).
4. Watch the progress sheet as each file converts.

On the Mac, open Show Log… from the Help menu for detailed per-file results — you can clear the log, open it in TextEdit, or reveal it in Finder. On iPhone and iPad, Show Log is available from the batch screen and the log can be shared with Share Log.

9. Presets & Apply to All

For consistency across a whole batch:

• Apply to All — set up a single file the way you like it, then copy its settings to the rest of the batch in one click.
• Presets — save your favorite configurations as named presets (Save as Preset…) and reuse them on future shoots.

10. Using RAW Batch on iPhone & iPad

The iOS app is built for working through a shoot away from the desk:

• Import — Import Files… from the Files app, Import from Photos… from your library, or open a RAW file in RAW Batch from another app.
• Browse and edit — iPhone shows the batch list with a detail view for the selected file; iPad shows both at once, with the batch on the left and the settings column on the right.
• Tune — the same RAW development controls, output settings, rotation, and scaling as the Mac, with a live preview (and a full-screen preview option).
• Apply to All — copy one file's settings across the batch, or save them as a preset.
• Convert — tap Convert and follow progress per file in the batch list.
• Export — tap Share on a converted file, or Share All, to save the images to Photos, write them to Files, AirDrop them, or send them to any other app.
• Log — open the log from the batch screen and share it with Share Log if you need support.

Free plan: 5 conversions per day. RAW Batch Pro removes the limit for $9.99/year or $24.99 once (lifetime).

11. Free vs Pro & Managing Your Purchase

macOS: open Subscription… from the Help menu, then choose the yearly subscription or the one-time lifetime purchase.

iPhone & iPad: tap Upgrade to Pro in the app, or open Subscription… to see your current plan. Restore Purchases re-applies a purchase on a new device, and Manage Subscription opens your Apple ID subscription settings.

12. Troubleshooting

Conversion fails: check that the output folder is accessible and writable, and that you have enough disk space. Open the log (Show Log… on the Mac, Show Log on iPhone and iPad) for details.

Files were ignored: only supported formats are accepted (camera RAW plus JPEG, PNG, TIFF, HEIC, BMP, GIF, JPEG-2000). Unsupported files are skipped with a note.

The Convert button is disabled: it only becomes active when there are pending files to convert. Add files first.

I hit my daily limit: the free plan allows 5 conversions per day, and only successful conversions count. Upgrade to Pro for unlimited conversions.

Can't import from Photos: make sure the app has permission to access your photo library, and that the Photos app is running and unlocked (macOS) or that the picker isn't blocked by a pending permission prompt (iPhone and iPad).

A file is still converting: conversions continue in the background on the Mac; you can cancel the batch from the progress sheet at any time. On iPhone and iPad, keep the app in the foreground until the batch finishes.
