300KB image requirement
- Target file size: 300 KB maximum.
- Useful when a portal allows a moderate file size and you want to preserve more detail.
- Often a better balance for photos, screenshots, and document images than very small limits.
A 300 KB target is less restrictive than smaller caps, but very large originals can still need some reduction in quality or dimensions.
Why an image may not meet the requirement
The source image may be too large to reach a very small file-size target without major quality loss.
The source image may be too small for the selected output dimensions.
The selected requirement may need a different image ratio.
Frequently asked questions
Will 300KB usually keep more detail than 100KB?
Yes. A higher target size generally allows the image to retain more clarity and texture than a much smaller cap.
Is 300KB suitable for document portal uploads?
It can be, if the portal allows that maximum. Always check the portal's stated limit because requirements vary.
Can I still use this if my image starts below 300KB?
You can, but it may not need much reduction. The target is most useful when the original file is above the allowed cap.
Does ImageSize store uploaded images?
Images are processed for the active request. No account is required, and the product does not include an image library or user gallery.
