FAQ

How do I get exactly 50 KB? ›
Use the target slider for 50 KB, optionally crop and reduce dimensions. The engine iteratively tunes quality.
Will the quality suffer? ›
Most images stay visually clean; extreme downscales or ultra-low targets may soften detail slightly.
Does Zero‑Upload affect results? ›
No quality loss—only processing location changes (local vs server). Privacy is maximized in Zero‑Upload.
Which format should I choose? ›
JPG for photos, WEBP for smallest modern size, PNG for transparency-critical graphics.
