Tips for Different Use Cases

For documents and most marketplaces, stick with white background and 92% quality — it's the universal safe default.

For e-commerce platforms that require pure white (255,255,255), the White preset is byte-exact — no tinting.

For print or archival, set quality to 100%. File size grows but encoder produces virtually no compression artifacts.

For web-bound images where size matters more than visual perfection, 75-85% drops file size dramatically with only mild quality loss.

Frequently Asked Questions

Why does my PNG get a black background when I convert it to JPG?

JPG does not support transparency. When a naive converter flattens a transparent PNG, it fills the alpha pixels with black by default. MiaoCut fills them with white (or any color you pick) so the result looks the way you expect — no surprise black blobs.

What background color should I pick?

White is the safe default for documents, e-commerce, and most marketplaces. Light gray works well for product photography. Black suits dark-themed designs. The custom color picker covers brand colors.

Is my image uploaded to a server?

No. This converter runs 100% in your browser using Canvas. Your image never leaves your device — nothing is uploaded, stored, or logged.

What JPG quality setting should I use?

92% is a balanced default — visually lossless for most photos with reasonable file size. Use 100% for print or archival. Use 75-85% if you need smaller files for the web and don't mind mild compression.

Can I convert WebP or other formats too?

Yes. The converter accepts PNG, WebP, and any format your browser can decode. The output is always JPG.
