Everything in one place

No browser tabs. No accounts. No uploads. Drag, pick a format, done.

100% Offline

Your files never leave your machine. No telemetry, no internet required, no exceptions — not even during conversion.

Batch Processing

Drop an entire folder and convert everything at once. Great for when you have 30 PNGs that all need to become JPEGs.

Auto Dark / Light Mode

Reads your Windows theme and switches instantly. Matches whatever you have on, no toggle needed.

Statistics Dashboard

Animated charts track your conversion history, volume over time, and which formats you reach for most.

Achievements

Streaks, milestones, animated unlocks. Optional — turn it off in Settings if you just want the converter.

Windows Context Menu

Right-click any file in Explorer → Convert with FCP. The app opens, converts, and closes on its own.

Multi-Engine Fallback

Chains FFmpeg, LibreOffice, Pandoc, and native libraries. If one tool isn't installed, the next one picks up.

Project Files

Save a conversion setup as .fcproj. Double-click later to restore the whole session instantly.

Multi-Language

Ships with French and English. Add any other language by dropping a .lang JSON file — no code needed.

What it converts

Documents, images, audio, video — all handled from one window.

Four steps, done

01

Download & Run

No install wizard if you go portable. One .exe — double-click, you're in. Under a minute.

02

Add Your Files

Drag them onto the window, onto the exe itself, or right-click in Explorer. Pick whichever feels natural.

03

Pick a Format

Select the output format and hit Convert. Batch mode works exactly the same way.

04

Done

Converted files are saved directly to your output folder. You can also enable Windows notifications to know when a conversion finishes, especially useful for large batches.

How it fits

Online tools are great for one-off conversions. FCP is for people who convert files regularly and don't want to keep uploading them somewhere.

Built by one person while studying

FCP is a solo project built in parallel with my studies. There's no big team or company behind it — just me creating and improving a tool I genuinely use myself. If it helps you out, a coffee or a star on GitHub is always appreciated.

One download. No account. No expiry. Runs entirely on your machine, as long as you want it to.
