Why AllToolsFree?

AllToolsFree is a collection of free online tools that run entirely in your web browser. Unlike services like iLovePDF, SmallPDF, or TinyPNG that upload your files to remote servers, AllToolsFree uses modern browser APIs to process everything locally on your device. Your files are never uploaded, making it the most private and secure option available.

Our PDF tools let you merge, compress, split, and convert PDF documents without installing any software. The image tools support compression, resizing, format conversion, and bulk processing for JPG, PNG, and WebP files. Developer tools include a JSON formatter, Base64 encoder, hash generator, UUID generator, timestamp converter, and more. Fun tools like the QR code generator, password generator, and meme maker are perfect for everyday tasks.

Every tool is designed to work on mobile and desktop, loads instantly with lazy code splitting, and can even work offline as an installable PWA. No accounts, no fees, no limits — just free tools that respect your privacy.
