How to reduce

Three ways to make files smaller

Lower quality smartly

Quality 40–95, balanced/fast/maximum. 85 is the sweet spot — preview per file.

Resize dimensions

Max W×H, downscale only, keep aspect. Off when you don’t need it.

Change format

Keep original or convert the batch to WebP/AVIF — smaller at same quality.
