QR codes for links, text, Wi-Fi and contact cards — one at a time or in bulk from a CSV.

Puts your brand colour and logo inside the code and downloads it as SVG or PNG. In bulk mode every row of a CSV becomes its own code and they all arrive in one ZIP. No sign-up, no watermark, no link that expires: the code carries the data itself.

JPEG, PNG, WebP and AVIF — shrink and convert in bulk without the files leaving your device.

Compresses images inside the browser with WebAssembly encoders and converts them to WebP or AVIF. Pick the quality and the largest dimension, see each file's before and after, download them all as one ZIP. Nothing is uploaded to a server.

Format, validate and minify JSON — and take n8n workflows apart.

Points at the line and column where broken JSON breaks, and pretty-prints or minifies the rest. When what you paste is an n8n workflow it counts the nodes by type, maps the connections and checks the parameters for keys, tokens or passwords written in plain text — before you share it.

Turns a cron expression into a plain Turkish or English sentence and lists the next runs.

Reads a five- or six-field cron expression back as a sentence, works out the next five runs in the time zone you pick and explains each field on its own. It also tells you what to watch for before pasting it into an n8n Schedule Trigger.

Code 128, EAN-13, EAN-8 and UPC-A; the GS1 check digit, and TSPL and ZPL label commands.

Draws the barcode as SVG or PNG, computes or verifies the check digit, and writes the TSPL (TSC) and ZPL (Zebra) commands you can send straight to a label printer. Pick the label size and the printer's resolution and the commands are written to those measurements. Paste a list and every line becomes its own label.
