CrossKit Image Compressor is a browser tool that shrinks JPG, PNG and WebP product photos so marketplace uploads stay under file-size caps. It is built for catalog work, not generic photo albums. You keep the same pixels you need for zoom while cutting bytes that slow Seller Central, Shopify and TikTok Shop uploads.
This page is a browser tool. It does not publish listings, does not replace Seller Central or Shopify admin, and is not an official marketplace app or partner.
You drop images into the page; compression runs in the browser with a quality slider and a before/after size readout. Files are not parked on a remote image farm. Download the lighter copies in the same tab and drop them into your listing assets folder.
A nine-image Amazon set often exceeds the practical upload budget when shot on a phone. Compress the white-background hero and secondary angles so the pack stays crisp at 1600 px but small enough for Seller Central.
Collection grids load many thumbnails at once. Compress lifestyle crops before you upload them to the theme so mobile shoppers are not waiting on 4 MB JPEGs.
Export a cover frame from your product video and compress it so the Shop card loads quickly in-feed without banding on skin or fabric.
Pick up to a recommended batch of about 20 files from the SKU folder you are listing this week, including hero and detail crops.
Start around 80 if the marketplace only cares about megabytes; drop a step if a single file still blocks upload. Watch the on-page size delta, not a guessed percentage.
Check zipper teeth, ingredient labels and white-background cutouts. If halos appear, raise quality on that file only and leave the rest.
Save the compressed files with the same SKU names you use in Seller Central or Shopify, then swap them in the image module without renaming the live listing.
Collect the 5-10 files for one marketplace upload (main image, detail images, manuals).
Process them in one pass; files stay in your browser and are never uploaded.
Check the before/after sizes against the marketplace limit, then upload the same day.
Doing this in a desktop editor means opening each SKU, exporting, and renaming by hand. Generic “compress anything” sites often strip EXIF and re-encode blindly. CrossKit keeps the loop in one browser tab with an explicit size comparison so you can stop when the marketplace upload succeeds.
Product images you select are processed in the browser. CrossKit does not upload them to train models or sell photo files to anyone.
