Compress images under 300KB for marketplace uploads
Many marketplaces and ads tools reject oversized photos. YourImagesKit Compress can binary-search quality to an exact KB target without sending files to a server.
When you need a KB target
Seller centers, chat uploads, and some ad managers enforce hard caps (often 200KB, 300KB, or 500KB). Shrinking only by “quality 80%” is guesswork — Exact target (KB) mode is built for these rules.
Recommended steps
Resize first if the photo is 4000px+ — huge dimensions fight compression. Then open Compress → Exact target (KB), set 300 (or your cap), set a sensible max edge (e.g. 1600), and download. Spot-check text on labels; if mushy, raise the KB budget slightly or sharpen before compressing.
Format notes
JPG is usually best for listing photos. Keep PNG for graphics with transparency (Cutout exports). Convert can move a batch to JPG/WebP before you compress for the final upload pack.
