How In-Browser Image Compression Works
1. Pure Local RAM Decoding
When you select an image, the browser decodes it via asynchronous Bitmaps. Your files never cross the network.
2. Web Worker Concurrency
Batch optimizations run across your computer's CPU cores via background threads, keeping your UI responsive at 60fps.
3. Smart Binary Solver
Need to meet strict upload limits (e.g. 200 KB)? Our binary search solver finds the highest fidelity that fits your byte constraint.
How do I compress images without losing quality?
Select WebP or JPEG with quality set between 75% and 85%. This strips high-frequency redundant digital noise while maintaining sharp visual clarity.
How does the Target File Size solver work?
The tool tests multiple quality compression curves in sub-second intervals in local memory to lock in the optimal resolution and quality that stays under your chosen KB limit.
Are EXIF and GPS location metadata removed?
Yes. In-browser canvas rasterization naturally scrubs camera serial numbers, lens profiles, and GPS coordinates for complete privacy before you share or upload.
