Choose The Right Tool For The Decision.

Open a practical utility, enter your figures or add files, and download results. Calculators show assumptions; reports help prioritize next actions.

01

Image To WebP + Compressor

Convert and compress multiple images locally. Compare savings and download every result.

Why It Matters

Heavy images slow down stores and articles. WebP conversion makes images easier to deliver while keeping control over visual quality.

Why Image Optimization Matters

02

Image Format Converter

Convert JPG, PNG and WebP images in bulk, with optional AVIF when supported.

Why It Matters

Different platforms work best with different image formats. Convert a batch without installing software, changing image dimensions or uploading photos to a server.

03

Etsy Fee Calculator

Estimate Etsy fees, Offsite Ads, and what you keep after costs.

Why It Matters

A good selling price can still deliver a poor margin after listing, transaction, processing, postage and advertising fees.

04

eCommerce Profit Calculator

Model revenue, payment fees, fulfillment, ads, refunds, and contribution.

Why It Matters

Sales reports do not show everything you keep. Shipping, advertising and returns can substantially change your bottom line.

05

Amazon FBA Profit Simulator

Estimate FBA or FBM profit, ROI, break-even price, and advertising headroom.

Why It Matters

Sales volume cannot fix a negative unit margin. Fulfillment, referrals, inbound costs and advertising must be considered before scaling.

Why Amazon Unit Economics Matter

06

Amazon PPC Search-Term Analyzer

Upload a search-term report and find wasted spend, candidates for negatives, and scaling opportunities.

Why It Matters

Account-wide ACoS can hide expensive nonconverting searches. Reviewing individual terms helps focus on where spend earns sales.

Why Search-Term Analysis Matters

07

Amazon ACoS & Break-Even Calculator

Compare advertising cost of sales with estimated break-even ACoS and product margin.

Why It Matters

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 Matters
Use it to answer

How much of my ad-attributed revenue am I spending on ads—and what is my estimated break-even point?

08

Amazon Search-Term Byte Counter

Check UTF-8 byte limits and repeated terms for Amazon backend Search Terms fields.

Why It Matters

Amazon backend Search Terms are measured in UTF-8 bytes, not only characters. The tool detects repeated words while helping you stay within the field limit.

Why Byte Limits Matter
Use it to answer

Are my Amazon backend search terms over the 250-byte limit?

09

Ecommerce Profit Margin Calculator

Estimate contribution, profit margin and major costs from store revenue and expenses.

Why It Matters

Revenue alone does not show profitability. Model goods, shipping, fees, advertising, refunds and other expenses in the same period.

Why Profit Margin Needs Full Costs
Use it to answer

After goods, shipping, fees and advertising, what margin is left?

Google SERP Snippet Preview

Draft and preview SEO titles and descriptions for desktop and mobile search results.

Why It Matters

Preview the presentation of an SEO title and description before publishing. Google may still generate a different snippet.

Why Search Previews Help
Use it to answer

How could this title and description read in a search result?

How The Toolkit Works

Useful Calculations. No Guesswork.

Every utility is designed around a specific decision, not a vanity metric.

Private Inputs

Calculations run inside your browser. Tool inputs stay in your browser unless you explicitly submit an expert-review request.

Transparent Assumptions

Cost fields are explicit, undefined results stay undefined, and figures are labeled as estimates when appropriate.

Clear Next Steps

Each tool explains what the result tells you, what it cannot prove, and which service may help implement the next step.

Have a tool idea your team keeps doing manually?

We can build that too.
