Right-Click Image Conversion

What's inside

Small download, not a small program

reaConverter is a fast, privacy-focused and free image converter that works offline. No setup hassle — just quick conversions and support for next-gen formats like WebP, AVIF, and JPEG XL (JXL).

Right-click conversion

Convert straight from Explorer's context menu. The app never has to open.

Batch workflow

Drop in hundreds of files or whole folder trees and convert them in one pass.

Editing tools

Resize, crop, rotate and watermark — applied during conversion.

Ultra-fast conversion

Uses every core your CPU has, so a large batch finishes while you wait.

Offline processing

Everything happens locally. Nothing is queued, stored or sent anywhere.

Windows Fluent UI

Built for Windows 11 — not a decade-old interface with a new icon on it.

Interface:
Load files
1 — add files
Convert files
2 — click Convert

Watch it run

How to use?

Using reaConverter is simple: Add your files, Select the output format, and click Convert — that’s it!

    Perfect for quick conversions! When I just need to turn a few BMPs into JPGs, this online tool saves me from installing software. Three clicks and done - couldn't be simpler!

    I deal with hundreds of images daily, and reaConverter has been a lifesaver. The Watch Folders feature lets me automate file conversions without lifting a finger. I set up a folder for incoming files and it automatically resizes, renames, and converts them into the formats I need. It's like having a personal assistant!

If you outgrow it

Lite is the floor, not the ceiling

The paid editions are the same program with more of it switched on. Anything you set up in Lite keeps working exactly the same way.
