How to Reduce Image File Size Online
Reducing image file sizes is often a strict requirement for online forms, job applications, and government portals. Many sites have strict limits, such as "Image must be under 50KB" or "Passport photo size limit 100KB." This Smart Image Reducer is engineered specifically for these scenarios.
Features of This Reducer
- Target Size Mode: Simply type "50" into the box, and our algorithm will iteratively compress and resize your image until it fits under 50KB. No more guessing quality percentages.
- Percentage Mode: For general optimization, you can choose a quality level (e.g., 70%) to shave off file size without a specific target in mind.
- Intelligent Scaling: If simply lowering the quality isn't enough to reach your target file size (e.g., trying to make a 10MB photo 20KB), the tool will smart-scale the dimensions of the image to ensure the target is met.
Why Reduce Locally?
Most online compressors upload your private photos to their servers to process them. This takes time and raises privacy concerns. This tool uses the HTML5 Canvas API to process everything directly in your browser. Your images never leave your device, making it safe for sensitive documents like IDs, signatures, and personal photos.
