Compress image to 500KB
Quick answer
500KB holds quite high quality, common on government and visa portals that allow larger uploads, and good whenever fine detail must stay visible.
500KB is the upload cap on many government and visa systems, and a go-to target when you want to keep high sharpness. Drop an image in and image cat compresses it toward 500KB locally — never uploaded.
How much quality 500KB holds
500KB gives a photo generous bitrate. Even high-resolution portraits, landscapes and scanned documents are usually indistinguishable from the original by eye at 500KB. It's ideal for formal files that must both meet a limit and stay detailed.
When to use it
Government uploads, visa documents, registration photos meant for printing and dense web heroes all suit 500KB. If the system is more lenient, 1MB gets even closer to lossless.
Frequently asked questions

image cat targets 500KB by binary-searching quality, approaching but not exceeding it. High-resolution images often hit it with almost no down-scaling, preserving near-original sharpness.
