Free online tools
Everyday tools that run inside your browser: PDFs, QR codes, images and passwords.
Free, safe and private: we ask for no personal data, and there are no hidden fees or subscriptions. Your files are processed on your device and never leave it.
Many of our clients and friends end up on paid platforms by mistake when what they need is free; that is why we published these tools.
PDF tools
Merge several PDFs, compress them, split by pages, add page numbers or a text watermark with the colour and position you want.
Sign PDF
Draw your signature with your mouse or finger, or upload an image, and stamp it on any page of a PDF before downloading it.
QR generator
QR codes in SVG, PNG or PDF from a link, a text or your WiFi details, so you can share the connection without dictating the password.
QR scanner
Read a QR code from an image or with your camera and check where it leads before opening it, with warnings for suspicious links.
Barcode generator
EAN-13, Code 128, Code 39 and more, in SVG or PNG. Paste a list of references and download all the labels together in a ZIP.
Image converter
Convert between JPG, PNG and WebP, resize and compress. Download each image on its own or all of them together in a ZIP.
Photo metadata cleaner
Find out what your photos carry hidden inside (GPS location, date, camera) and download a clean, metadata-free copy.
Favicon generator
Turn your logo into every favicon a modern website needs: favicon.ico, PNGs, apple-touch-icon and manifest, with the HTML snippet.
Password generator
Random passwords with the length and character sets you choose, generated with the browser cryptographic random generator.
File hash
Get the SHA-256, SHA-1 or MD5 hash of any file and check it against an expected value to verify it has not been tampered with.
NIF, CIF & IBAN validator
Validate Spanish NIF, NIE, CIF and IBAN one by one or as a pasted list, and generate valid fictitious data for your test environments.
CSV utilities
Fix the delimiter so Excel opens the CSV properly, remove duplicates, pick columns and convert to JSON without uploading the file anywhere.
Text compare
Paste two versions of a text and see what changed, word by word. Ideal for contracts and terms.
Cron expression editor
Write or build cron expressions both ways, with a plain-language explanation and the next five run times.
Word to WhatsApp converter
Paste Word text or upload a .docx and get a message ready for WhatsApp, with bold, italics and lists already converted.
Word to clean HTML converter
Turn a Word document into clean, readable HTML with no inline styles, Mso classes or proprietary Office tags.
PDF & image OCR
Pull the text out of a scanned PDF or a photo and download it as .txt. Recognition runs in your browser, with no document sent to any service.
String encoder
Encode and decode text as Base64, URL encoding, HTML or XML entities, a JSON string, hexadecimal, Unicode escapes and ROT13, both ways.
