◎ EXIF Lens

Support

Answers to the questions we receive most. If yours is not here, the contact details are at the bottom of the page.

Getting started

Tap Choose a photo, select an image from Files, and EXIF Lens shows supported metadata fields grouped by camera, exposure, location, dates, author and image. The available details depend on what is stored in the photo.

Removing metadata

Tap Remove metadata. The app writes a cleaned copy and offers to save it to your photo library. Your original is never modified, so you can always compare the two.

Common questions

Does my photo leave my device?

No. Reading and cleaning happen entirely on your device and your photo is never uploaded, so both work in Airplane Mode. The only part of the app that talks to the network is Apple's App Store, when it fetches the price, completes a purchase or restores one.

Why does the cleaned copy look rotated?

It should not. The app keeps the original EXIF orientation, so the copy displays exactly as the original did. If you see a rotation, please report it with the original file's format.

Is the picture re-compressed when I clean it?

For JPEG and PNG, no. The app rewrites the container: the compressed pixels are copied byte for byte and only the metadata blocks are removed, so a cleaned JPEG or PNG has no second round of compression. HEIC, TIFF and RAW files have to be written by the system, so those are re-encoded.

Which formats are supported?

Any image the system can decode — JPEG, HEIC, PNG, TIFF and most RAW formats.

Cleaning keeps the original container where the system can write it back: JPEG, HEIC, PNG and TIFF stay as they are. Formats the system cannot write back — RAW, GIF, BMP and WebP — are saved as JPEG, and the copy is named .jpg so the file name always matches what the file actually contains.

What exactly is removed?

GPS coordinates and altitude, camera make and model, lens details, serial numbers, owner, artist and copyright strings, capture and digitised timestamps, plus IPTC title, keywords and caption. Pixel data, colour profile and resolution are preserved.

I bought the unlock on another device

Open the paywall and tap Restore purchase. Purchases restore through your Apple Account at no additional cost.

What does it cost?

Reading a photo is free. Removing metadata is a one-time purchase of US$1.99, and it unlocks cleaning permanently — no subscription and no renewal. Apple charges the equivalent amount in your own currency; the paywall always shows the exact local price returned by the App Store for your storefront.

Can I use it offline?

Yes. Reading and cleaning never need a connection. Buying the unlock is handled by Apple's App Store, so that one step needs a connection the first time; it works offline after that, and Restore purchase can be used again whenever you reinstall.

How do I request a refund?

Refunds are handled by Apple. Visit reportaproblem.apple.com and select the purchase.
