Gerador de código QRCreate QR codes for text, URLs, Wi-Fi, vCard, email, phone, SMS, geo, calendar, WhatsApp, Telegram, Bitcoin, Ethereum, UPI and JSON, with error correction, quiet zone, colours and PNG/SVG export.Gerador de URL código QRTurn any link into a scannable QR code, adding https:// when the scheme is missing and warning about unsafe schemes.Gerador de Wi-Fi código QRBuild a standards-compliant WIFI: payload with SSID, password, WPA/WEP/open encryption and hidden-network flag so phones join the network on scan.Gerador de vCard código QRGenerate a vCard 3.0 contact QR code with name, organisation, title, phone, email, website, address and note.Gerador de MECARD código QRBuild a MECARD contact payload — the compact alternative to vCard that fits in a smaller, lower-version QR symbol.Gerador de e-mail código QRCreate a mailto: QR code with prefilled recipient, subject and body.Gerador de Phone número código QRGenerate a tel: URI QR code that opens the dialler with the number already filled in.Gerador de SMS código QRBuild an sms: URI QR code with a prefilled message body, encoded for both iOS and Android.Gerador de Geo Location código QRCreate a geo: URI QR code from latitude and longitude, validating the coordinate ranges before encoding.Gerador de Calendar Event código QRGenerate an iCalendar VEVENT QR code with start, end, title, location and description that phones add straight to the calendar.Gerador de WhatsApp código QRBuild a wa.me link QR code with an optional prefilled message, normalising the phone number to digits with country code.Gerador de Telegram código QRCreate a t.me link QR code that opens a Telegram chat or channel.Gerador de Bitcoin Payment código QRBuild a BIP-21 bitcoin: URI QR code with address, amount, label and message, and check the address shape.Gerador de Ethereum Payment código QRGenerate an EIP-681 ethereum: URI QR code with address, value and gas limit, validating the 0x + 40 hex format.Gerador de UPI Payment código QRBuild a upi://pay QR code with payee VPA, name, amount, note and currency, validating the VPA and amount formats.Gerador de JSON código QRValidate and minify JSON before encoding it, so the payload fits in the smallest possible QR version.Decodificador de código QRUpload a PNG, JPG, WebP or GIF and decode the QR code locally with jsQR, then identify the payload type and parse its fields.QR Payload Type DetectorIdentify 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.Validador de código QRCheck 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.Analisador de QR PayloadSplit a raw QR payload into its component fields — Wi-Fi SSID and encryption, vCard name and phone, geo coordinates, URI query parameters.Formatador de QR PayloadBuild a correct standard payload string from JSON fields, applying the escaping rules each format requires.código QR Scan TestRender 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 código QRGenerates 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

PDF Tools

Ferramenta de PDF fusãoMerge two or more PDF files into one document — pages keep their original size and quality, the order follows your selection, and everything runs in your browser: no upload, no sign-up, nothing ever leaves your machine.Conversor de imagem to PDFConvert JPG and PNG images into a single PDF in your browser — every photo becomes a page in the order you picked them, original resolution is kept, and nothing is uploaded: no account, no queue, no size games.Scanner de Photo to PDFTurn phone photos into a clean scanned-style A4 PDF — up to 30 images are centered and fitted onto uniform pages automatically, and the whole scan runs locally like a scanner app without ever uploading a photo.PDF RotatorRotate PDF pages in your browser — turn every page, or just the ones you name (like 1,3-5), 90° either way or upside down, with no re-encoding, no upload and no sign-up. Password-protected PDFs are not supported.inversão PDF PagesFlip a PDF end to end — the last page becomes page 1 and vice versa, no page content is re-encoded, and the whole reorder runs locally in your browser with no upload and no sign-up.Conversor de PDF to textoConvert a PDF to text in your browser — every page is parsed locally with pdf.js, lines come out in reading order, and you get word and character counts plus a .txt download. No upload, no sign-up; scans (no OCR) and password-protected files are declined, and layout is not preserved.Extract texto from PDFExtract the text out of a PDF in one tab: click or drop your file and pdf.js pulls every selectable line locally — the document itself never leaves your machine. Per-page failures degrade to a placeholder instead of killing the run.Extrator de PDF textoA local PDF text extractor: open the file with the pdf.js engine right in this page, copy the plain text or download it as .txt, with page/word/character counts shown up front. Image-only scans and encrypted files are declined up front — this tool is honest about what it reads.Conversor de PDF to palavrasConvert a PDF to a Word (.docx) file in your browser: pdf.js reads the selectable text, then a minimal reflowed Word document is assembled paragraph by paragraph — counts up front, copy and download included, no upload and no sign-up. Fonts, images and page layout from the original are not carried across (this is an honest text rebuild), scans get no OCR, and password-protected PDFs are declined.Conversor de PDF to DOCXTurn a PDF into a .docx you can keep editing: the text is extracted locally with the same pdf.js engine as our PDF text tools and rebuilt as clean Word paragraphs with the same builder as our Text to Word page. Reflowed plain text on purpose — not a pixel-faithful conversion; dense scans (no OCR), encrypted files and documents past the size gates are declined honestly, and nothing is ever uploaded.
