FAQ

How does this compressor reduce image file size without losing noticeable quality?

It optimizes quantization tables, color subsampling, and image encoding headers. Keeping the quality between 70% and 80% typically cuts file size by over 50% with near-lossless visual fidelity.

Can I batch compress multiple photos and set a target KB limit?

Yes. You can select multiple images for parallel processing and use the target file size mode to aim for specific upload requirements like 100KB or 200KB.

Are my images uploaded to any remote server during compression?

No. TrueFree Tools performs all image processing entirely client-side using browser APIs and WebAssembly. Your photos never leave your device.
