Frequently Asked Questions (FAQs)
How does the "Target Size (KB)" feature work?
When you enter a target size (e.g., 50KB), our advanced browser-based Binary Search algorithm automatically tests different compression levels in milliseconds to find the maximum possible quality that fits exactly under your required size limit.
Are my images safe?
Absolutely. PinSave uses HTML5 Canvas technology. All compression calculations happen right on your device (mobile or PC). No images are ever sent to our servers.
Which format gives the smallest file size?
WEBP format generally provides 25-30% smaller file sizes compared to traditional JPGs at the exact same visual quality. We highly recommend selecting WEBP for maximum compression.
