Filee for Windows 10 and 11: Free File Conversion, PDF Tools and Optional Engine Downloads

What Filee is​

Filee is a converter for Windows 10/11 (64-bit) and Linux, with a macOS build marked as a preview. The developer's site lists the license as MIT, with Windows 10/11 x64, Linux x64/ARM64 (Ubuntu 22.04+) and macOS 13+ (preview) as platforms. The site says it has no ads, no watermarks, no account, no trial and no file-count or file-size limits of its own.

It is new. Daily Launch lists a launch date of 29 September 2026. That tracker also shows the GitHub repository gaining about 1.3k stars on 28 October. The repository now shows more than 21,000 stars. Popularity says nothing about quality or security. It does mean the project has a lot of eyes on it, and a lot of fast-moving code.

The gesture that gives it away​

The central idea is a modifier-key drag. Select files in File Explorer, hold Ctrl (or another key you choose) and drag them. A donut-shaped menu opens at your cursor and offers formats that fit what you selected. Drop the files on one, and the converted copies appear next to the originals.

Filee has other ways in too, according to its site:

• the right-click "Convert with Filee" entry, which can be added to the top-level Windows 11 menu
• Send To
• a keyboard shortcut
• a drop zone in the main window
• a command-line tool

Shah's review says it feels almost like a native Windows feature, and that is his opinion. Windows 11 has no built-in general-purpose file converter, so it is easy to see why that appeals.

Beyond conversion​

The "dozen little apps" headline comes from what the donut can do besides converting. Per Shah's walkthrough and the developer's documentation:

• Image edits: resizing by percentage or width, a quality slider, rotate, flip and grayscale. Pixelate hides sensitive areas. Pressing Tab on the donut shows more tools, including metadata removal, background removal and crop.
• PDF handling: merge (with ordering), split, page ranges and compression. Shah says this replaced PDF24 for him.
• Batch work: the site says files convert in parallel and one failure doesn't stop the rest. Presets can merge a batch into one PDF or pack it into a ZIP.
• Watch Folders: a folder can convert whatever lands in it, with naming rules and the option to move originals aside. The site shows filee watch . --to pdf --move-originals as an example.
• Browser drags: you can drag a picture out of a web page and convert it on the way down. The repository says links are fetched without your browser sign-in, so don't expect it to grab authenticated downloads.

Shah says he stopped using PowerToys Image Resizer, PDF24 and PowerRename-style renaming for these jobs. That is one writer's experience over a few weeks. The documentation supports the features. It does not show that Filee beats dedicated tools at their own jobs.

A quick crop or pixelate is not a substitute for a real image editor. A merge-and-split PDF preset is not a full PDF suite. If you need batch renaming with regular expressions, check whether Filee's naming presets cover your case.

The format count is a moving target​

Read the "270+ formats" claim carefully. Different pages give different numbers:

• MakeUseOf says more than 270.
• The GitHub README headline says 270 formats, while the repository's About text says 263.
• The Filee site FAQ says 255 formats in 18 categories.
• SourceForge lists 263.
• Earlier descriptions, such as AlternativeTo and Daily Launch, cited 180.

The count has clearly grown quickly as the project adds formats. The number that matters is what works after install. The site says 147 of the 255 work right after install, and the rest use optional engines. I'm relying on the FAQ text in the source material for that figure.

Optional engines​

Several conversions need downloads. According to the Filee site:

• FFmpeg (about 100 MB): video and audio, subtitle extraction and saving HEIC.
• LibreOffice (about 420 MB): older formats such as DOC, PPT, ODT and RTF.
• Calibre: rare e-book formats and MOBI/AZW3 output.
• Ghostscript: EPS and PostScript.
• Pandoc (about 42 MB): LaTeX, Org, AsciiDoc and similar markup.

You can tick them in the installer or download them in the app later. They can be removed, and Filee reuses copies it finds already on your PC. Those sizes are the site's estimates and may change.

So a video converter is not built into the base install. If you plan to convert video, expect an FFmpeg download first.

Office files and privacy​

Filee says DOCX, XLSX, CSV and PPTX files convert with built-in engines. It says it does not use Microsoft Office, even when Office is installed. That means no Office dependency. It does not mean Filee replaces Office, and fidelity on complex documents is something to test yourself.

On privacy, the developer says conversions run locally and nothing is uploaded. The internet is used only to download optional engines and check for updates. For anyone who has pasted a contract into a random web converter, that is a real improvement. It is still a developer claim, not an independent audit. Evaluate it the way you would any new tool that touches your documents.

Install notes for Windows​

• Installer or portable: the Setup installer puts Filee in Program Files for all users and needs administrator approval once. The app then runs as a normal user. A portable ZIP runs without installing. Silent installs use /VERYSILENT /SUPPRESSMSGBOXES.
• Microsoft Store: the site now shows a Microsoft Store download option alongside the direct download.
• Signing: the repository says current Windows releases are code-signed, and SmartScreen may still warn about a new release until it builds reputation. Releases through 2.0.0 were unsigned. Verify the download source before you click through any warning.
• Older Windows 10 systems: the site describes a case where Filee and its installer exit silently, with no window or error. It affects Windows 10 PCs that haven't been updated in a long time, on processors supporting Hardware-enforced Stack Protection (CET). The recommended fix is to install the latest cumulative update. The site also documents a per-program exploit-protection workaround. That weakens a security mitigation for that program, so updating Windows is the better route.

Should you drop the other apps?​

Filee is a strong candidate for the "first thing I install" slot. It is free and local, and the drag gesture means few clicks. It also covers the small jobs that usually send people hunting for single-purpose utilities.

A sensible approach is to try it alongside your current tools for a week. Keep the dedicated apps for heavy editing, complex PDF work, or anything that needs guaranteed output fidelity. Shah's closing complaint is only about the name, which is a fair sign for a young project. Still, it launched at the end of September 2026, so give it time to prove itself on stability and security.
