500KBCompress image to 500KB
Quick answer
When the destination allows a larger file, try 500KB for detailed photos or scans. Check text, pixels and actual bytes; file size alone does not establish quality.

Check each image, its dimensions and file size before downloading.
500KB can be a target for images with more detail, but first confirm the destination’s actual byte limit. Drop an image in for local compression, then check that output text and edges remain clear. This preset uses 500 KiB (512,000 bytes). If the destination uses decimal KB/MB, check its byte cap and use a lower custom target.
How much quality 500KB holds
500KB provides more space than smaller presets, but high-resolution photos or dense scans can still lose detail. Inspect important text, fine lines and textures at a readable scale, keeping the original for comparison.
When to use it
Try it for document images, photos or detailed web images when permitted by the destination. For printing, separately check output pixels and print dimensions. If a larger file is allowed, compare a 1MB output without treating it as lossless.
Frequently asked questions
File size alone cannot answer that. Print clarity also depends on output pixels, print dimensions and source detail. Preview at the intended print size, retain the original and use a higher-resolution output when needed.
Check the actual output bytes. The 500KB preset uses 500 KiB (512,000 bytes), which may exceed a 500,000-byte destination cap; use a lower custom target in that case. Compression may also miss its target, so rely on the actual result.
