Test Your iPhone Camera in the Browser
Run the test below in Safari, then use the iOS fixes underneath. iPhone camera access in a browser is governed by three separate layers — Safari's site permission, the iOS camera permission, and Screen Time restrictions — and any one of them will block it.

What Your Camera Is Actually Delivering
- Camera:—
- Resolution:—
- Frame Rate:—
- Aspect Ratio:—
- Microphone Detected:—
These are the values your browser negotiated with the camera just now, not the numbers on the box. A difference between the two is exactly what the guidance below is for.
Granting camera access on iOS
Safari's per-site settingWith this page open, tap the aA icon in the address bar, choose Website Settings, and set Camera to Allow. Safari asks once per site and remembers a refusal.
Global Safari settingGo to Settings > Apps > Safari > Camera and set it to Ask or Allow. On older iOS versions this path is Settings > Safari > Camera.
Screen Time can hide the camera entirelySettings > Screen Time > Content & Privacy Restrictions > Allowed Apps contains a Camera toggle. When off, the Camera app disappears from the home screen and every browser loses access with no error explaining why. This catches out a lot of people with parental controls enabled.
Front and rear cameras in the browser
Browsers default to the front lensA web page requesting a camera receives the front-facing lens by default, which is what you want for a call or a self-view test.
Switching lenses is site-dependentA site must explicitly request the rear camera. There is no browser-level control that flips it, so if a page offers no camera selector it cannot be switched.
Multiple rear lenses report as oneOn iPhones with several rear cameras, the browser is generally offered a single combined rear device rather than separate ultra-wide and telephoto options.
Third-party browsers and in-app views
Chrome and Firefox on iOSAll iOS browsers use Apple's WebKit engine underneath, so behaviour is broadly the same. Each app still needs its own camera permission under Settings > Privacy & Security > Camera.
In-app browsers are the common failureLinks opened inside Instagram, Facebook or a messaging app run in a restricted in-app browser where camera access frequently fails. Use the share menu to open the page in Safari properly.
Low Power ModeLow Power Mode can reduce camera frame rates. If the reading looks low, disable it and re-test.
FAQ
Frequently Asked Questions
Why does Safari say camera access is denied on my iPhone?Tap the aA icon in Safari's address bar, choose Website Settings, and set Camera to Allow. Also check Settings > Apps > Safari > Camera is set to Ask or Allow, and that Screen Time restrictions are not blocking the camera entirely.
How do I switch between the front and rear camera in a browser?The website has to offer the choice — there is no iOS or Safari setting that switches it. Browsers receive the front camera by default, and only a page with its own camera selector can request the rear lens.
Why does the camera fail when I open a link from Instagram?Links opened inside apps run in a restricted in-app browser that often cannot access the camera. Use the share menu to open the page in Safari, where full camera access works normally.
Can Screen Time block my iPhone camera?Yes, and it does so silently. Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps contains a Camera toggle. With it off, the Camera app vanishes and browsers lose access without a clear error.
Supported Browsers on iOS
Camera access depends on WebRTC support, which varies by browser even on the same device.
| Browser | Support | Notes |
|---|---|---|
| Safari | Full support | Native WebRTC implementation |
| Chrome for iOS | Full support | Required by Apple to use WebKit (Safari's engine) internally, so behavior matches Safari |
| Firefox for iOS | Full support | Also WebKit-based on iOS, same underlying engine as Safari |
| Edge for iOS | Full support | Also WebKit-based on iOS |
