Why Filesmith

Your files never leave your device
Everything runs directly in your browser using WebAssembly. No files are uploaded to any server — ever. What you convert or edit stays on your machine.
Edit before you convert
Crop, resize, rotate, flip, and adjust brightness or contrast right in the browser — no extra apps needed. Edit first, then export in any format.
Batch convert anything
Drop an entire folder of images at once. Preview each one side-by-side before saving. Edit and convert all with a few clicks.

How it works

1
Drop your files
Drag images or video onto the box, or click to browse. Batch upload a whole folder at once.
2
Edit or convert
Crop, resize, rotate and adjust your images. Or pick a format and quality level for conversion.
3
Save your files
Download one at a time or hit Save All. Your files are ready instantly.
