Compress Images to 240KB Exact Target Size
Compress high-resolution photos to exactly 240KB client-side. Precise byte-level calibration with lossless color conversion. 100% private in-browser.
Instant client-side compression · Up to 2 GB per file · Zero server upload
Technical Architecture & In-Browser Processing
Targeting exactly 240KB provides the ideal balance between high compression ratios and pristine portrait clarity for immigration and consulate upload specifications. FitSize runs a dual-pass binary search to converge within 1% of the 240KB threshold. sRGB color matrices are strictly calibrated to avoid chromatic drift, ensuring your portraits maintain true-to-life tones without digital compression artifacts.
Engineered strictly for US Department of State Diversity Visa (DV Lottery) and USCIS immigration requirements, this profile forces exact 600x600 pixel square geometry and 24-bit sRGB color depth. Our client-side pipeline eliminates compression artifacts while ensuring the final byte count settles comfortably beneath the mandatory 240KB maximum.
Frequently Asked Questions
How accurate is the 240KB target size?
FitSize converges within 1% of 240KB, guaranteeing your file will never exceed the 240KB threshold.
Will colors shift after compression?
No. The sRGB color profile is strictly preserved, preventing color shifts or washing out.
Can square portraits be compressed to 240KB?
Yes. Square 1:1 aspect ratio images compress cleanly with preserved proportions.
