QR and Utility Toolkit: Share, Convert, Compare, Capture

Use QR, barcode, timestamp, text diff, pinyin, and screenshot tools as a lightweight daily toolkit.

Share without accounts

Generate QR codes and barcodes for links, labels, and quick handoffs. Downloads are generated locally, so you can create assets without logging into a separate service.

Compare and timestamp

Use Text Diff to review short edits, Timestamp for logs or API payloads, and Pinyin/Simplified-Traditional conversion when preparing bilingual copy.

Capture only what you need

The screenshot tool lets you choose a screen or tab, crop in the browser, then export a PNG without sending the image to a server.
