圖片 ResizerResize images locally without uploading them.圖片 Format 轉換器Convert PNG ↔ JPEG ↔ WebP in the browser.圖片壓縮工具Re-encode JPEG/WebP with a quality slider and size preview.圖片 to Base64 轉換器Embed images as Base64 data URIs.Base64 to 圖片轉換器Preview and download an image from Base64 data.圖片顏色選擇器Pick pixel colors from any uploaded image.SVG to JPG 轉換器Convert SVG to JPG right in the browser — the background is flattened to white (or any colour you pick), the size follows your request, and the vector file is only ever opened inside your own tab.ScanforEmbedded 檔案Scans the data for potential embedded files by looking for magic bytes at all offsets. This operation is prone to false positives. WARNING: Files over about 100KB in size will take a VERY long time to process.

URL 二維碼產生器Turn any link into a scannable QR code, adding https:// when the scheme is missing and warning about unsafe schemes.Wi-Fi 二維碼產生器Build a standards-compliant WIFI: payload with SSID, password, WPA/WEP/open encryption and hidden-network flag so phones join the network on scan.vCard 二維碼產生器Generate a vCard 3.0 contact QR code with name, organisation, title, phone, email, website, address and note.MECARD 二維碼產生器Build a MECARD contact payload — the compact alternative to vCard that fits in a smaller, lower-version QR symbol.電子郵件二維碼產生器Create a mailto: QR code with prefilled recipient, subject and body.Phone 數字二維碼產生器Generate a tel: URI QR code that opens the dialler with the number already filled in.SMS 二維碼產生器Build an sms: URI QR code with a prefilled message body, encoded for both iOS and Android.Geo Location 二維碼產生器Create a geo: URI QR code from latitude and longitude, validating the coordinate ranges before encoding.Calendar Event 二維碼產生器Generate an iCalendar VEVENT QR code with start, end, title, location and description that phones add straight to the calendar.WhatsApp 二維碼產生器Build a wa.me link QR code with an optional prefilled message, normalising the phone number to digits with country code.Telegram 二維碼產生器Create a t.me link QR code that opens a Telegram chat or channel.Bitcoin Payment 二維碼產生器Build a BIP-21 bitcoin: URI QR code with address, amount, label and message, and check the address shape.Ethereum Payment 二維碼產生器Generate an EIP-681 ethereum: URI QR code with address, value and gas limit, validating the 0x + 40 hex format.UPI Payment 二維碼產生器Build a upi://pay QR code with payee VPA, name, amount, note and currency, validating the VPA and amount formats.JSON 二維碼產生器Validate and minify JSON before encoding it, so the payload fits in the smallest possible QR version.二維碼解碼器Upload a PNG, JPG, WebP or GIF and decode the QR code locally with jsQR, then identify the payload type and parse its fields.QRPayloadTypeDetectorIdentify what a decoded QR payload actually is — URL, Wi-Fi, vCard, MECARD, geo, calendar, email, phone, SMS, Bitcoin, Ethereum, UPI, WhatsApp, Telegram, JSON, XML or plain text — and split it into fields.二維碼驗證器Check a payload before you print it: capacity at the chosen error correction level, URL/email/Wi-Fi/vCard/geo/Bitcoin/Ethereum/UPI/JSON format, unsafe schemes and scannability risks.QR Payload 剖析器Split a raw QR payload into its component fields — Wi-Fi SSID and encryption, vCard name and phone, geo coordinates, URI query parameters.QR Payload 格式化工具Build a correct standard payload string from JSON fields, applying the escaping rules each format requires.二維碼 ScanTestRender your QR settings and then decode the result locally, comparing it to the original payload, plus quiet zone, contrast, density and capacity checks with a Good / Warning / Risk verdict.Generate 二維碼Generates a Quick Response (QR) code from the input text. A QR code is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that con
