ImageLab Tools

ImageLab Tools gives Android 10+ users a fast, private way to process photos on-device. The AppCompat-based app starts from a unified Main page and opens separate Editor, Guide, About, and Privacy pages. Each subpage has its own title bar, Back button, and focused content. Open a local image with the AndroidX document picker, then apply filters such as mono, sepia, invert, edge, posterize, and sharpen. Fine-tune brightness, contrast, and saturation with live preview controls, rotate or flip the image, crop to square or 4:3, restore the source, and save the final JPEG to the Pictures/ImageLabTools album with Android 10 scoped storage.

The app is designed for lightweight utility use: no account, no cloud , and no network permission. Image processing happens directly on the device.
