A passport photo under 100 KB that still fits the frame
PIXLFLW crops to the standard passport frame, 35 × 45 mm (413 × 531 px at 300 dpi), and exports it under 100 KB in the same step. Drop a photo above and the studio finds the face, places the frame, and searches for the highest JPEG quality that still lands under 100 KB before you download.
Why the frame and the size do not solve each other
A form that states both a frame and a size limit checks each one on its own. Getting the crop right does nothing for the byte count, and shrinking the file without keeping the crop locked can stretch or crop the face the wrong way. This page runs both checks in one pass, so the file you download matches the print size, the pixel size and the 100 KB ceiling at once.
What the encoder does as the budget drops
Reaching 100 KB is a search, not a single setting: the encoder tries a JPEG quality, checks the byte count, and steps the quality down until the file lands under 100 KB. Above roughly 100 KB that search alone almost always works and the pixel count at 413 × 531 px is left alone. Below that the quality curve runs out of room, so the search also shrinks the pixel dimensions, and the export is reported back with its new width and height instead of silently missing the ceiling. The photo that comes out is smaller and noticeably softer than one exported at a looser budget, which is the cost of a tight limit rather than a flaw in the encoder.
