FAQ

How do I get exactly 100 KB?
Use the target slider for 100 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.

100KB — Why?

100KB is ideal for faster uploads, email attachments, and forms that require small file sizes, while maintaining visual quality.

Best practices to hit 100KB with good quality

Great for general web use at ~1400–1600px; subtle gradients and skin tones fare well.
