Image Toolbox

Project Overview

ImageToolbox is a comprehensive Android image editing application offering a wide range of features for manipulating and processing images. It's designed to be user-friendly while providing powerful capabilities suitable for both casual users and professionals like photographers or developers.

What is the project about?

The project is an Android application focused on providing a diverse set of image editing tools within a single, cohesive interface. It goes beyond basic editing, offering advanced features like filter creation, EXIF data manipulation, and encryption.

What problem does it solve?

It solves the problem of needing multiple, separate applications for different image editing tasks. Users often have to switch between apps for resizing, applying filters, converting formats, removing backgrounds, etc. ImageToolbox consolidates these functions, streamlining the image editing workflow. It also addresses the need for advanced features like detailed EXIF editing, image encryption, and high-quality format conversions, which are often missing in simpler image editors.

Features of the project:

  • Batch Processing: Apply operations to multiple images at once.
  • Extensive Filters: Over 230 filters, including color adjustments, artistic effects, blurs, distortions, and dithering algorithms.
  • Custom Filter Creation: Users can design and share their own filters.
  • Encryption/Decryption: Secure images using over 100 different algorithms.
  • Markup: Add stickers, text, and freehand drawings.
  • OCR (Optical Character Recognition): Extract text from images in 120+ languages.
  • EXIF Editing: Modify or remove image metadata.
  • Image Loading: Load images from the internet.
  • Image Stitching/Stacking/Splitting: Combine or divide images in various ways.
  • Background Removal: Automatic and manual background removal tools.
  • Watermarking: Add text, image, or timestamp watermarks.
  • Drawing Tools: A comprehensive set of drawing tools for annotations and creative edits.
  • Resizing: Multiple resizing methods with various scaling algorithms and color spaces.
  • GIF/WEBP/APNG/JXL Conversion: Support for animated image formats.
  • PDF Tools: Convert between images and PDF files.
