KillEXIF for Mac and Windows: what’s new

The highlights of each version. Not every fix and not every day of work: what changes for someone using the app.

macOS

1.0.1 · September 24, 2026

Published on the Mac App Store. Fixes found by cleaning thousands of real files, most of them already in the Windows app.

  • TIFF files with EXIF no longer come out broken: 1.0 left 60 of 68 real TIFFs unable to open in Preview and Photos. Now all 68 open, and the two blocks Photoshop keeps in a TIFF — resources and layers, with thumbnail and hidden layer names — go too.
  • PDFs from banks and insurers no longer hide their author: a statement or a policy could come out with its title, author and dates inside, and verified. Out of 200 real PDFs, none keeps a field and none comes out broken.
  • iPhone videos say where they were shot: the location is read, shown as a location, and “Location only” removes it.
  • iPhone HDR photos stay HDR: cleaning them no longer takes away their brightness, and only the two pieces Apple needs for it are kept.
  • An XMP with coordinates counts as location: “Location only” removes the XMP that says where you were and keeps the title and copyright of an edited photo.
  • Documents from Google Docs and openpyxl are cleaned as documents, not as ZIP files; Opus and Ogg files with cover art come out verified.

1.0 · August 26, 2026

Published on the Mac App Store. The app is free to download; the paid formats and the watched folders are bought inside it.

  • Fourteen formats, cleaned by the same engine as the website rewritten in Swift, and held to the same conformance suite: both implementations have to pass it file by file.
  • Nothing is re-encoded. Metadata blocks are removed and the compressed data is left untouched, byte for byte — the image you get back is the image you had.
  • Every cleaned file is read back to check that what was meant to go is gone, and whatever could not be removed is named instead of quietly left behind.
  • Seeing what a file says about you is free, in all fourteen formats. Cleaning JPEG, PNG, GIF and office documents is free too, with no cap on how many.
  • Three profiles — Maximum cleaning, For social media, Location only — and all three are free.
  • Cleaning without opening the app: Finder extension, the Services menu, “Open with”, dropping onto the Dock icon, and Shortcuts.
  • Watched folders: anything that lands in one is cleaned on its own while KillEXIF is running.
  • When a file is replaced, the original goes to the Trash and can be recovered until you empty it — and if the writing fails, the original goes back where it was.
  • Thousands of files at a time, with progress and a Stop that never leaves a file half written.
  • No size ceiling, no account, no connection: nothing leaves the machine, including the files the app never uploads.
  • Seven languages — English, Spanish, French, German, Italian and Portuguese for both Portugal and Brazil — and the app’s language is chosen inside the app, without changing the whole Mac.

Windows

1.0.1 · September 24, 2026

Published on the Microsoft Store, for Windows 11: the first version on sale. The app is free to download; the paid formats and the watched folders are bought inside it.

  • One package for every PC, x64 and ARM64 alike.
  • The Microsoft Store now recognises the app’s seven languages; the pilot declared only English.
  • Everything in 1.0, below.

1.0 · September 23, 2026

Pilot version, uploaded to the Microsoft Store for certification. This is what the app does:

  • The same fourteen formats as the Mac app, cleaned by the engine rewritten in C# and held to the same conformance suite as the website and the Mac app: the three implementations have to pass it file by file.
  • Nothing is re-encoded. Metadata blocks are removed and images and video come out identical, byte for byte. iPhone HDR photos stay HDR.
  • Every cleaned file is read back to check that what was meant to go is gone. RAW negatives, bare AAC files and ZIP64 archives are refused, and the app says why.
  • Seeing what a file says about you is free, in all fourteen formats. Cleaning JPEG, PNG, GIF and office documents — Word, Excel, PowerPoint and OpenDocument — is free too, with no cap on how many.
  • Three profiles — Maximum cleaning, For social media, Location only — and you keep what you choose: orientation, colour profile, copyright.
  • “Clean with KillEXIF” in the File Explorer right-click menu and in “Open with”: the files open in the app, so you see what they say before anything is removed.
  • Watched folders, each with its own profile: anything that lands in one is cleaned while KillEXIF is open. With the app closed, nothing is watched.
  • Online-only OneDrive files are downloaded as they are read, and if one cannot be downloaded, the app says so.
  • When a file is replaced, the original goes to the Recycle Bin; or the clean copy is saved next to it.
  • Whole folders and batches of thousands of files, with progress you can follow and cancel.
  • No sign-up and no server: nothing is uploaded. The only connection is the Microsoft Store, for the licence.
  • Seven languages: English, Spanish, French, German, Italian and Portuguese for both Portugal and Brazil.
