About KitParlor

What KitParlor does

Selling products online means dealing with a surprising amount of fiddly image work: checking whether a design is high-resolution enough to print, resizing listing photos to exact marketplace dimensions, turning artwork into a seamless repeating pattern, pulling brand colors out of a mockup, or adding a clean die-cut border to a sticker. Most of these jobs are too small to justify opening heavy design software, yet awkward to do by hand.

The other half of the job is exact numbers with a deadline attached — a character limit that changes on a specific date, a duty rule that starts on 1 July, a fee schedule that decides whether an order was worth packing. Those questions have real answers, but they are scattered across help-centre pages, out-of-date forum threads and spreadsheets you rebuild from scratch every time.

KitParlor collects both kinds of task into a set of single-purpose tools that each do one thing well and load instantly. There is no account to create, nothing to install, and no watermark on your results.

Three things you can settle here in a minute

Rather than describe the site in the abstract, here is the kind of question it is built for.

What the EU's €3 parcel duty really costs you. The €150 duty exemption ended on 1 July 2026 and a flat €3 charge replaced it until 1 July 2028. The detail that catches sellers out is that it is counted per tariff classification, not per physical unit — five identical t-shirts in one box are charged €3, but three t-shirts plus a watch are charged €6, because that is two commodity codes. Import VAT is then assessed on a base that includes the duty. The EU Import VAT & Low-Value Duty Estimator does the arithmetic; the guide explains the classification test and why consolidating parcels is now the cheaper direction.
Whether your Amazon title is about to be truncated. Amazon's 75-character title rule takes effect on 27 July 2026, and it is not the only ceiling in a listing — backend search terms are capped at 250 bytes, so an accented character or an emoji quietly costs more than one. Go over and Amazon indexes none of that field. The 75-character title checker and the title & byte counter show both counts live, with the background here.
What is actually left after fees. The Marketplace Fee & Profit Calculator compares Etsy, Amazon Handmade and eBay on the same order, and keeps buyer-side sales tax and VAT out of the profit line, because that money is pass-through and never yours. It also handles the awkward cases, like eBay's per-order fee changing at the $10 mark.

Where the numbers come from

Anything on this site that can go out of date carries the date it was checked and a link to the primary source. The fee calculator is stamped “Rates verified: 2026-07-20” against Etsy's, Amazon's and eBay's own fee pages. The EU duty tool is stamped “Flat-duty rule verified 2026-07-21” and links to the European Commission announcement and the DG TAXUD legal text rather than asking you to take our word for it.

Just as importantly, where a number cannot be verified we say so instead of inventing one. The Print on Demand Profit Calculator carries no “checked on” date for its preset supplier costs, because print providers only quote a real price inside a logged-in account and anything we printed would be a guess wearing a date. The US Landed Cost & DDP Price Builder ships with no duty-rate table at all — every rate is your input, and it points you at the USITC tariff schedule instead — on the view that an out-of-date rate that looks authoritative is worse than no rate.

We do get things wrong. If you spot a stale figure or a tool that misbehaves, the contact page reaches us at contact@kitparlor.com and corrections are the most useful mail we get.

There are 27 tools in the full tool index. They fall into three rough groups:

Images and print files — the Seamless Pattern Maker, Etsy & Amazon Image Resizer, Sticker Border Maker, Print Bleed & Safe-Area Generator, POD Print File Checker, T-Shirt Print Placement Generator, Tumbler Wrap Template Generator, Wall Art Size Guide Generator, Cricut SVG to PNG Converter, Product Shadow Generator, Social Media Crop Tool, Color Code Converter and the Image to ASCII Art Converter.
Listing checks — the Amazon Main Image Compliance Checker, Etsy Crop Preview, Etsy 20MB File Fitter, Etsy Video Spec Checker, Etsy Title & Tag Counter and the Amazon title & keyword byte counter.
Money, shipping and compliance — the Marketplace Fee & Profit Calculator, Print on Demand Profit Calculator, US Landed Cost & DDP Price Builder, EU Import VAT & Low-Value Duty Estimator, GPSR Safety Label Builder, Amazon FBA Barcode Generator and the Digital Product License Generator.

Guides

Eleven longer written guides cover the questions the tools keep raising. On files and artwork: DPI vs PPI, Etsy image sizes, how to make seamless patterns, print-on-demand image requirements, sticker sizes for die-cut printing, how to measure a tumbler for a wrap template and t-shirt print placement measurements. On the rules that keep changing: the EU's €3 parcel duty, what has to go on a GPSR label, pricing for the US after DDP became mandatory and Amazon's 75-character title limit.

The break room

Packing orders and waiting on a print proof leaves a lot of small gaps, so the site keeps twelve games with a goal and a score — mini golf, breakout, a daily wire puzzle and a 3D voxel roguelike — and a quieter fidget hub holding five toys with nothing to win, plus three quick tests: a reaction time test, a hearing age test and a color hue test. They are filed under the footer rather than the main menu, because they are not why you came here.

Your files stay on your device

Every KitParlor tool runs entirely in your web browser. When you drop in an image it is read on your own machine with standard browser APIs — FileReader, canvas and object URLs — and the result is drawn and downloaded locally. This is not a promise about what we do with your uploads; there are no uploads. Not one of the 27 tool pages contains a single call that sends your file or your figures anywhere.

The practical test: load a tool page, turn off your internet connection, and it will keep working. That is a deliberate design choice. Your product designs are your business, and the safest way to handle them is to never let them leave your machine in the first place. It is also why a bug report cannot include your file — we have no copy of anything you have worked on. For the full details, including what our advertising partner sees, read the Privacy Policy.

How KitParlor stays free

Everything here is free, with no account, no trial and no paid tier — the site is supported by advertising, which is the one part of the page that is not ours and does load from a third party. Ads cover hosting so the tools can stay open to everyone. They sit around the tools rather than inside them, and nothing is gated behind clicking one.
