Smart Compression Features
Intelligent Quality
Our algorithm finds the optimal compression settings to reach 300KB while preserving visual quality. The compressor adjusts JPEG quality, color subsampling, and metadata stripping based on the image content.
Private Processing
Your images are processed locally in your browser. Nothing is uploaded to our servers — the platform only sees the final compressed result you choose to upload.
💡 Compressing to 300KB: What to Expect
Platform-optimized compression (300KB): Web platforms and content management systems benefit from pre-optimized images. When you upload an image, many platforms re-compress it — starting with a file already at 300KB prevents double-compression artifacts and gives you control over where quality is lost.
Best format: WebP produces the best quality-to-size ratio for modern web delivery. If compatibility with older browsers matters, JPEG at 75-85% quality is the safe default. Resize your image to the platform's display resolution first — sending a 4000px image to be displayed at 800px wastes bandwidth.
Optimization workflow: Resize to the platform's recommended dimensions, then compress to 300KB for the fastest possible page loads.
