Definition

What is Image Compressor?

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.

What it is not

What Image Compressor is not

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.

How it works

How Image Compressor works

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.

Use cases

When to use Image Compressor

Amazon main-image batch before upload

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.

Shopify theme weight on collection pages

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.

TikTok Shop video cover stills

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.

Step-by-step

How to use Image Compressor

  1. 1
    Select product JPEGs or PNGs

    Pick up to a recommended batch of about 20 files from the SKU folder you are listing this week, including hero and detail crops.

  2. 2
    Set quality against the marketplace cap

    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.

  3. 3
    Preview edges and text overlays

    Check zipper teeth, ingredient labels and white-background cutouts. If halos appear, raise quality on that file only and leave the rest.

  4. 4
    Download and replace the listing set

    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.

Walkthrough

A real use case for Image Compressor

  1. 1

    Collect the 5-10 files for one marketplace upload (main image, detail images, manuals).

  2. 2

    Process them in one pass; files stay in your browser and are never uploaded.

  3. 3

    Check the before/after sizes against the marketplace limit, then upload the same day.

Comparison

CrossKit vs doing it manually

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.

Privacy

How CrossKit handles your data

Product images you select are processed in the browser. CrossKit does not upload them to train models or sell photo files to anyone.
