Free online tools that run in your browser
Merge PDFs, count words, make a QR code, convert HEIC, pull text from an image or shrink a batch of photos. All six tools do the work on your device, so your files and text never reach a server.

What they have in common
Every tool here loads open-source libraries from this site the first time you use it: pdf-lib and Mozilla's pdf.js for PDFs, qrcode-generator for QR codes, heic2any for iPhone photos, Tesseract for OCR and browser-image-compression for images. After that the work happens on your computer or phone. There's no account, no watermark and no daily limit, because nothing costs us anything to run. You can check it yourself in the Network tab of the developer tools (F12): you won't see your file being uploaded.
