Compress JPEG to 590KB
ResizeBox treats 590 KB as 604160 bytes. That is 10 KB below binary 600 KB, but it exceeds a decimal 600000-byte limit, so verify the destination's byte convention before using 590 KB as upload headroom.

Know What 590 KB Means Near a 600 KB Limit
Use the larger photo budget without assuming every service measures 600 KB the same way.
Binary 590 KB Can Exceed Decimal 600 KB
The target equals 604160 bytes. It is 10240 bytes below binary 600 KB, yet 4160 bytes above a decimal 600000-byte ceiling, so the destination convention matters.
Ninety Kilobytes More Than 500 KB
Compared with a 500 KB target, 590 KB gives JPEG 92160 additional bytes in ResizeBox. That extra room can preserve more fine texture or larger dimensions before scaling becomes necessary.
590 KB Usually Preserves More Than It Removes
At this budget, ordinary photos often need only moderate JPEG adjustment. Automatic dimension reduction remains a fallback for unusually large or noisy sources rather than the expected first step.
Oversized Photos May Shrink
Width and height can come down if quality adjustment cannot bring a large JPEG toward 590 KB.
JPEG-Only Download
Common image inputs are converted to JPEG, which cannot retain transparent areas.

Compress locally toward 590 KB, preserve everyday photo detail where possible, and verify the exported byte size against the destination's own 600 KB rule.
590 KB JPEG Compression FAQ
Answers about byte conventions, the extra room over 500 KB and final JPEG behavior near a 600 KB-labelled limit.
No. ResizeBox 590 KB equals 604160 bytes, which is below binary 600 KB but above a decimal 600000-byte limit. Use the destination byte definition as the real boundary.
It adds 92160 bytes in ResizeBox. That extra 90 KB can preserve more fine detail or larger dimensions, although it also means the file may exceed a decimal 600000-byte limit.
Fine hair, fabric, gradients and textured backgrounds can retain more information because the encoder has an extra 90 KB to work with before it needs stronger compression or smaller dimensions.
No. Some complex sources can remain above the target, so inspect the result.
Only when JPEG quality changes still leave a very large or complex image over the target. At this budget, ordinary photos are more likely to keep their requested dimensions than at much smaller targets.
It is flattened because this page always exports JPEG.
Target search is skipped, but JPEG export may still re-encode the source.
No. Processing runs locally on your device.
