Light Image Resizer, developed by ObviousIdea, is an intuitive and versatile software designed to help you optimize, resize and manage your image collections. It pairs a friendly interface with powerful batch-processing features, ideal for photographers, designers and anyone handling large photo libraries.
This software supports batch resizing, allowing users to process multiple images simultaneously, saving time and effort. Whether you need to resize photos for email attachments, web uploads, or print projects, Light Image Resizer ensures high-quality results while maintaining file integrity. It supports a wide array of formats, including JPG, PNG, BMP, GIF, TIFF, WebP, HEIC, AVIF, JPEG XL (JXL), PDF, DNG, CR2, CR3, providing flexibility for various use cases.
Light Image Resizer includes advanced options for renaming, converting formats, and compressing files to save storage space. Its built-in tools apply effects, watermarks and custom profiles consistently across image sets. Integration with Windows Explorer means you can resize images directly from your file manager with a simple right-click, and the built-in Light Image Editor handles touch-ups such as text, blur, and shapes without leaving the app.
AI features are available on your terms: AI Vision can annotate each image in a batch and AI image generation can retouch photos, using Gemini, OpenAI or OpenRouter models, or a fully local model through Ollama so nothing leaves your PC. Nothing is switched on by default, and your model choice is saved with each profile.
Non-destructive by design, the software can keep copies of your originals, shows a live preview of every adjustment before you commit, and can even read text from JPEG images with OCR as part of a batch.
Light Image Resizer is a lightweight yet powerful tool, updated frequently with dedicated support on Windows 11 and 10. The free version lets you process up to 100 images; a one-time license unlocks unlimited use.
