Common Questions
Everything you need to know
Can I resize to exactly 20KB?
We try our best! Our smart algorithm adjusts quality to get as close as possible to your target size without exceeding it.
Will the quality be bad?
If you ask for a very small size (like 5KB for a large photo), quality will decrease. For reasonable targets like 50KB-100KB, it looks great.
What formats are supported?
JPG, PNG, and WebP are supported.
Targeting a very small file size for a high-resolution image may result in significant quality loss. We prioritize meeting the size limit over visual fidelity.
