About KitParlor
KitParlor is a small, focused collection of free image tools for people who sell online — Etsy shop owners, print-on-demand designers, sticker makers and marketplace sellers.
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.
KitParlor collects these everyday tasks 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.
Our tools
- Seamless Pattern Maker — turn any tile into a perfectly repeating, edge-matched pattern.
- Etsy & Amazon Fee Calculator — work out your marketplace fees and net profit per sale before you list.
- Marketplace Image Resizer — resize and pad listings to exact Etsy, Amazon and eBay sizes.
- Color Code Converter — convert HEX, RGB, HSL & CMYK and check WCAG contrast.
- Sticker Border Tool — add a clean white outline around a transparent PNG for die-cut printing.
Privacy comes first
Every KitParlor tool runs entirely in your web browser. When you drop in an image, it is read locally on your own device using standard browser APIs — it is never uploaded to a server, never stored, and never seen by us or anyone else. You can even disconnect from the internet after a tool page loads and it will keep working.
This 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. For the full details, see our Privacy Policy.
How KitParlor stays free
KitParlor is free to use and supported by unobtrusive advertising. Ads help cover hosting so the tools can stay open to everyone without a paywall or signup. The tools themselves work the same whether or not you ever click an ad.
