How to transfer RAW photos from your camera to iPhone (and why it fails)
You shot RAW and want the real files on your iPhone. Short answer: a card reader into the Photos app is the simplest way, a tethering app is the automatic way, and the camera maker's app works if you change its settings — most failures come from resized transfers, RAW-only shooting or a camera iOS doesn't yet read.
Option 1: a card reader or cable into Photos
Plug an SD or CFexpress card reader into the iPhone — directly on a USB-C iPhone, or through Apple's Lightning to USB camera adapter on older models. Open Photos and use Import to copy the RAW files across. You can also connect many cameras straight to the iPhone with a cable and import the same way. This copies the original files, at full resolution, with no wireless step.
Option 2: the camera maker's app
Canon Camera Connect, Nikon SnapBridge, Sony's Creators' App and Fujifilm XApp can all send photos over Wi-Fi, but RAW needs the right settings. Canon's app imports CR3 as RAW only when you choose its RAW option, and RAW burst files can't be sent. SnapBridge's automatic transfer sends small JPEGs; NEF files are a manual download from Wi-Fi-capable cameras. Sony's app lets you choose 2 MP or original size, and RAW depends on the body. On recent Fujifilm bodies with current firmware, XApp can send RAF files — set Photo resize to original size.
Option 3: tether the camera to the iPhone
A tethering app copies each file off the camera the moment it's written, so there's nothing to import afterwards. CloudTether does this over a USB-C cable or Wi-Fi for Canon, Nikon, Sony and Fujifilm, transferring the original RAW — CR3, CR2, NEF, ARW, RAF and others — or JPEG, every frame.
Why RAW transfers fail: the file was resized
The most common surprise. Wireless transfers in the makers' apps are often set to smaller sizes for speed, and some convert RAW to JPEG on the way. If you got a 2 MP or 1920-pixel JPEG instead of your RAW, check the app's size and RAW options and the camera's own auto-send size.
Why RAW transfers fail: RAW-only shooting
If the camera records only RAW, apps that send JPEGs have nothing to send at full size and may generate a small preview instead. Shooting RAW+JPEG gives the app a full JPEG to send and keeps the RAW for later, or use a method that copies RAW directly.
Why RAW transfers fail: iOS can't read that camera yet
Photos shows and edits RAW only for cameras on Apple's supported RAW list, and very new bodies are added in iOS updates. Until then, files may import but show only a preview or not open. Update iOS, or copy the files into the Files app and open them in an editor such as Lightroom that supports your camera.
Why RAW transfers fail: it shows as a JPEG
When you import a RAW+JPEG pair, Photos shows them as a single photo and displays the JPEG. The RAW is still there, and editors that support RAW can use it.
Why RAW transfers fail: space and time
RAW files are large — often 20 to 50 MB or more each — so a big batch needs free space on the iPhone and, over Wi-Fi, patience. Imports fail when the iPhone runs out of space, so check storage before a big batch. Wi-Fi transfers also stop if the phone leaves the camera's network or the camera goes to sleep; a cable avoids both.
The automatic way: every RAW as you shoot
If you want every RAW on your iPhone without importing at the end of the day, tether. With CloudTether, plug a USB-C cable from the camera into the iPhone (set Sony to PC Remote and Fujifilm to USB tether; turn a Canon's Wi-Fi off first). Each full-resolution file comes off the camera seconds after you take it — a 33 MB Canon EOS R1 CR3 took a median 1.46 s over USB in our logs. Keep copies in Photos or Files, send them to Dropbox, Google Drive, a gallery or an FTP server, or send only the JPEGs and leave RAW on the card. There's a 7-day free trial.
FAQ
How do I get RAW photos from my camera to my iPhone?
Use a card reader and import with the Photos app, change the maker's app to its RAW or original-size option, or tether the camera with an app like CloudTether to copy every RAW automatically.
Why do my RAW files arrive as small JPEGs?
The app was set to a resized transfer, converts RAW to JPEG, or the camera recorded only RAW and the app sent a preview. Check the size and RAW options, or copy the RAW directly.
Can the iPhone open Canon CR3, Nikon NEF, Sony ARW and Fujifilm RAF files?
Yes, for cameras on Apple's supported RAW list. Very new cameras are added in iOS updates; until then, use an editor that supports your camera.
Do I need an adapter to connect a card reader or camera to an iPhone?
USB-C iPhones connect directly. Lightning iPhones need Apple's Lightning to USB camera adapter.
Can I transfer RAW wirelessly?
Yes, with most makers' apps on supported cameras (with the right settings), or with CloudTether over the camera's Wi-Fi — verified on Canon. USB is faster for big RAW files.
