Print-quality photos for online submission. High-res marketing assets. Magazine-quality digital images. Fine art reproduction for web galleries.
Format Tips for 500 KB
500KB JPEG at 2500px wide quality ~90 — good enough for 8×10" prints at 250 DPI. For true print quality, consider TIFF or maximum-quality JPEG (2-5MB) instead. 500KB is the upper limit of what's practical for web delivery.
