Open a practical utility, enter your figures or add files, and download results. Calculators show assumptions; reports help prioritize next actions.
Convert and compress multiple images locally. Compare savings and download every result.
Heavy images slow down stores and articles. WebP conversion makes images easier to deliver while keeping control over visual quality.
Why Image Optimization MattersConvert JPG, PNG and WebP images in bulk, with optional AVIF when supported.
Different platforms work best with different image formats. Convert a batch without installing software, changing image dimensions or uploading photos to a server.
Why Image Formats MatterEstimate Etsy fees, Offsite Ads, and what you keep after costs.
A good selling price can still deliver a poor margin after listing, transaction, processing, postage and advertising fees.
Why Etsy Fee Estimates MatterModel revenue, payment fees, fulfillment, ads, refunds, and contribution.
Sales reports do not show everything you keep. Shipping, advertising and returns can substantially change your bottom line.
Why Revenue Alone Is Not EnoughEstimate FBA or FBM profit, ROI, break-even price, and advertising headroom.
Sales volume cannot fix a negative unit margin. Fulfillment, referrals, inbound costs and advertising must be considered before scaling.
Why Amazon Unit Economics MatterUpload a search-term report and find wasted spend, candidates for negatives, and scaling opportunities.
Account-wide ACoS can hide expensive nonconverting searches. Reviewing individual terms helps focus on where spend earns sales.
Why Search-Term Analysis MattersCompare advertising cost of sales with estimated break-even ACoS and product margin.
An ACoS target is meaningful only in the context of product margin. Compare ad costs with product-level economics before adjusting bids.
Why Break-Even ACoS MattersHow much of my ad-attributed revenue am I spending on ads—and what is my estimated break-even point?

Amazon sellers and listing editors checking Search Terms field input.Estimate contribution, profit margin and major costs from store revenue and expenses.

Why Profit Margin Needs Full CostsAfter goods, shipping, fees and advertising, what margin is left?
Store owners comparing product or campaign contribution before making pricing decisions.Draft and preview SEO titles and descriptions for desktop and mobile search results.

Why Search Previews HelpHow could this title and description read in a search result?
Editors, Shopify/WooCommerce teams and SEO writers preparing search snippets.Every utility is designed around a specific decision, not a vanity metric.
