A comfortable target — quality stays close to the original even on large photos. The encoder binary-searches the JPEG/WebP quality to fit just under 300 KB while keeping the image as sharp as possible.
FAQ
Is 300 KB enough quality for a passport photo?
Yes — 100 KB and above is enough for most government portals at 413×531 px or 600×600 px.
Why is the output still above 300 KB?
If the source resolution is very high, the encoder cannot reach the target without progressive downscaling. Reduce the pixel size or switch to WebP.
Does it work with iPhone HEIC files?
Yes, HEIC is converted to JPEG locally before compression.
