Reduce image file sizes with real-time visual comparison and target size constraints. 100% processed in local browser memory.
Frequently Asked Questions
Clear technical answers on compression, privacy, and algorithms.
How do I compress images without losing visual quality?
Select WebP or JPEG with quality set between 75% and 85%. This discards imperceptible high-frequency color data while preserving sharp outlines and natural textures.
How does the Target File Size solver work?
Our binary search algorithm executes rapid sub-second micro-compressions locally in your browser to calculate the highest possible visual quality that strictly satisfies your target limit.
Are EXIF metadata and GPS locations stripped?
Yes. In-browser canvas rasterization scrubs camera serial numbers, lens profiles, and GPS location coordinates before you save or share.
