How to install

  1. Download the installer and run it: choose whether to install Fukon for you only (no administrator rights) or for all users. Then start it from the Start menu.
  2. Prefer the portable version? Unzip the ZIP anywhere you like, for example C:\Fukon, and double-click Fukon.exe.
  3. In the Library, create a catalogue with + (a catalogue is just a named list of folders) and add the folders of your photos.
  4. To uninstall: Windows Settings > Apps, or delete the folder of the portable version. Your photos and the .dop / .xmp files next to them are never touched; settings and catalogues are removed only if you ask.

Windows says “Windows protected your PC”?

Fukon is new and not digitally signed yet (a signing certificate is one of the things your donations help to pay for), so Windows SmartScreen warns about it like it does for any unknown program. Click “More info”, then “Run anyway”.

To be sure that the file is the one published here, compare its SHA-256 with the one above. In PowerShell, in the folder of the download:

Get-FileHash .\Fukon-1.1.0-win64-setup.exe -Algorithm SHA256

Requirements

  • Windows 11, 64-bit.
  • No administrator rights needed, nothing else to download.
  • A graphics card with Direct3D 11 is optional: Fukon can draw the photo on it (experimental, off by default).

What is in the package

One folder (the same in the installer and in the ZIP) with Fukon.exe, libraw.dll (RAW decoding), cwebp.exe, avifenc.exe and cjxl.exe (WebP, AVIF and JPEG XL files of the export), the lensfun folder (the database of lenses for the lens correction), the Microsoft Visual C++ runtime that libraw.dll needs, the license texts of the third-party software, a README and the CHANGELOG. Fukon saves its settings in the fukon folder of your user profile, and your edits next to your photos.

Good to know

  • Your RAW files are never changed; keep backups of your photos anyway, as with any program.
  • Camera color profiles are not there yet. See what is coming next
  • Windows only for now. About macOS

What’s new

Version 1.1.0 · 2026-11-13

Fukon 1.1: free rotation on the picture, lens correction, spot removal and clone, creative vignette, history and named snapshots of the edits, virtual copies, more flexible presets and preset packs, new export options, thumbnails kept on disk, bulk rename, compare and survey in the Library.

New

  • Free rotation on the picture: draw a line along the horizon with the straighten tool, or drag just outside the crop frame.
  • Lens correction: distortion, vignetting and lateral chromatic aberration, from the data the camera writes in the RAW file or from the lensfun database (the lens is recognized by itself, or chosen by hand).
  • Spot removal and clone: one click removes a spot (the source is picked by itself and can be moved), with circles or brush strokes, healed or cloned.
  • Creative vignette after the crop: amount, midpoint, roundness, feather and highlights.
  • History of the edits: every step of the photo in a list; a click goes back to it, the pointer over a step shows it.
  • Named snapshots of the edits, kept with the photo and taken back with one click.
  • Virtual copies: several developments of the same photo without copying the RAW. In the strip they always follow their RAW, with their number in Roman numerals on the picture.
  • The tone curve on the picture: drag a tone of the photo up or down and the curve follows.
  • Color grading and the color mixer now work inside masks too.
  • Presets: amount from 0 to 100%, an add mode that keeps your other edits, favorites, your own order, duplicate and search.
  • Preset packs (.fkpresets) to share your own presets, and to import them.
  • Export several sizes at once (from @0.5x to @4x).
  • Export with a maximum file size: the best quality that fits is found by itself.
  • JPEG export: progressive files and optimized tables (smaller files, same picture).
  • Rendering intent of the export (perceptual or relative colorimetric), with a preview of the colors the chosen space cannot hold.
  • Thumbnails kept on disk: a folder seen before opens at once.
  • Bulk rename (F2) with a name scheme (date, counter, camera, text), a preview and undo; the .dop and .xmp files follow.
  • Compare (two photos side by side, zoom and place linked) and Survey (the chosen photos in a grid) in the Library; several photos are chosen in the strip with Ctrl + click, Shift + click and Ctrl+A.
  • The maker notes of Canon, Sony, Panasonic and Olympus / OM System in the metadata, checked on real files.

Changed

  • The graphics card (experimental) also draws the lens correction, the spots and the vignette.
  • Deleting a photo from the disk also deletes its virtual copies (the confirmation says so).

Fixed

  • Long items of the thumbnail's menu were cut off.
  • The metadata of Panasonic RW2 files showed some rows with a wrong meaning and repeated others: now they are left out.

Old versions

Version 1.0.1 · 2026-11-12

Fukon 1.0.1 opens the RAW files of every camera that LibRaw supports, not only Nikon and Fujifilm, and every photo now gets a proper thumbnail.

Fixed

  • Version 1.0 listed only NEF and RAF files in the folders: now the RAW files of every camera that LibRaw supports show up (Canon CR2 / CR3, Sony ARW, Panasonic RW2, Olympus / OM ORF, Pentax PEF, DNG, Hasselblad, Leica, Phase One and more).
  • Photos whose file has no usable preview inside (none, a tiny one or one of another shape, as in some DNG, Hasselblad and Leica files) now get their thumbnail and their Library picture from the photo itself, the right shape.
  • The thumbnail is now chosen among all the previews inside the file: a Canon or Pentax file no longer gives its full-size picture for a thumbnail, and the colorless RGB thumbnail of a Canon CR2 is never used.

Version 1.0.0 · 2026-11-11

Fukon 1.0: monitor color management, JPEG, PNG and TIFF as sources, export to AVIF, JPEG XL and HEIC, a split before/after view, named curves, search and filters in the strip, an installer, a quick guide, “Report a problem” and an optional update check.

New

  • Monitor color management: the photo, the thumbnails and the presets are shown through the profile of the monitor the window is on (Preferences > Image), so colors are right on wide-gamut displays too; it follows the window to another monitor.
  • JPEG, PNG and TIFF as sources: they show up in the folders and are developed with the same tools, in 16 bits, with their color profile and EXIF orientation. An export never overwrites the picture it comes from.
  • Export to AVIF (8, 10 or 12 bit), JPEG XL (8 or 16 bit, also lossless) and HEIC (with the HEVC extension of Windows), with the color profile and the EXIF data.
  • Export: five ways to set the size (long side, short side, a box, percent, megapixels), export presets with a name, a watermark made from a logo (PNG with transparency) and one animated GIF of a whole folder.
  • A split before/after view in the Develop module, with a line you can drag.
  • Named tone curves: save the curves of a photo (all five channels), use them on any other photo, rename and delete them.
  • Search, filter and sort the strip: by name, tag, camera or lens; by status, stars, color and tag; by name, date taken or rating. Each folder remembers its choice.
  • Six new colored filters: reverse and horizon graduates and graduates from below (38 filters in all).
  • An installer (for you only or for all users, Start menu shortcut, uninstall that keeps your settings unless you ask), next to the portable zip.
  • A quick guide in the program (F1) with all the shortcuts, and a welcome at the first start.
  • Report a problem (menu ≡): a text with the version, your system and the last errors, without your user name and your folders, to send by e-mail; the program keeps a log of its errors on your computer.
  • Check for updates (menu ≡), and at start if you want it (off unless you say yes): it only reads the number of the latest version from the website and installs nothing.
  • A splash screen at start, and the logo in the top bar.

Changed

  • A more compact interface: the status of a photo as icons in the right column, one menu for the preset column, a bin on the tile of a preset, the mask tools as icons and the masks with their parts in one tree.
  • The empty Lab tab is gone.
  • Very large photos are exported with much less memory (the detail filters work in bands).

Fixed

  • Many tooltips of the main window (menu, catalogue and folder buttons, search, filter, thumbnail size) did not show up: now they do, and the module tabs have their own.

Version 0.9.0.2 · 2026-11-10

Export, copy and sync of edits, presets (built-in, your own and imported from Lightroom, ON1 and Capture One), colored filters, black and white with film grain, and a right-click menu on thumbnails.

New

  • Export to JPEG, PNG, TIFF (8 and 16 bit), WebP and GIF: the file matches what you see on screen, with the output color space and embedded ICC profile, resizing, output sharpening, a text watermark, metadata (never the GPS position) and a file name template. One photo or a whole folder, with a progress window.
  • Copy, paste and sync edits: choose which groups to copy (white balance, tone, color, curves, grading, detail, geometry, masks...) and apply them to another photo, or to a whole folder, in one undoable step.
  • Presets, in the left column of the Develop module: 37 built-in looks in four groups (Classics, B&W, Film, Special), your own presets (create, update, rename, delete), a live thumbnail of the photo you are working on for each one, and a preview on the big picture while you hover.
  • Import presets from Lightroom (.xmp, .lrtemplate), ON1 (.ONPreset) and Capture One (.costylepack), also from a ZIP with many presets: they appear as a tree by collection, with a report of what could and could not be converted.
  • Colored filters, in the new Filters tab: 32 filters (warming and cooling correction, special, darker sky, graduated neutral density, graduated colors), and a Filter section in the Base tab for the whole photo or inside a mask.
  • Black and white: a switch in the color mixer, eight classic black and white looks (including the yellow, orange, red, green and blue filters) and twelve film-style looks.
  • Film grain (amount and size) in the Base tab, the same on screen, in thumbnails and in exported files.
  • A right-click menu on every thumbnail: revert to original, rotate left, rotate right, and delete from disk (it asks first, then erases the RAW file and its .dop and .xmp for good).
  • A new application icon and an About dialog with the version, the website and the donation link.

Changed

  • The thumbnails of the filmstrip and the picture of the Library now show your real development, and keep it the next time you open the folder (it is stored in the fukon folder of your profile; the RAW file is never touched).
  • The graphics card (experimental) also draws colored filters, grain and the thumbnails of the presets.
  • Dialogs: the action button comes first and Cancel last, in a row on the right with the same margins all around; in Export the Choose... button for the folder sits next to the field, with an icon.
  • The ZIP now contains cwebp.exe (for WebP) and this CHANGELOG.
