Frequently asked questions

What files does Nits open?

Nits opens 16-bit and HDR TIFF files, including gain-map and floating-point TIFFs. Support for more formats (HEIC, AVIF, OpenEXR) is on the roadmap.

Why don’t I see the HDR “pop” in the App Store screenshots?

The App Store displays images in standard dynamic range, so the full HDR effect only appears once you open your own images on your iPad’s HDR display.

How do I see image information?

Tap the info control to open the EXIF panel (focal length, aperture, shutter, ISO, lens, color profile, bit depth, and HDR headroom), and the chart control to toggle the live RGB histogram.

How do I move between images?

Open any image from a folder and Nits loads the whole folder. Swipe left or right at fit zoom to step through, or tap a thumbnail in the filmstrip to jump directly.

Does Nits collect any of my data?

No. Nits does not collect, store, or transmit any personal data or images. Your files never leave your device.
