Free PDF & Image Tools
No Upload, 100% Private

SlimPDF offers a complete suite of free tools for working with PDFs and images. Unlike most online tools that require you to upload files to remote servers, SlimPDF processes everything locally in your browser. This means faster results, zero privacy risk, and no file size limits. Whether you need to compress a large PDF for email, merge multiple documents into one, resize photos for social media, or convert images between formats, SlimPDF has you covered.

Every file you process with SlimPDF stays on your device. Our tools use client-side JavaScript libraries like pdf-lib and the Canvas API to handle all operations directly in your browser. No files are ever transmitted to a server. This privacy-first approach means your sensitive documents, personal photos, and confidential files are never exposed to third parties. The tools even work offline once the page has loaded.

Using SlimPDF is simple: select a tool, drag and drop your file, adjust settings if needed, and download the result. There is no account to create, no software to install, and no subscription to pay. SlimPDF works on any modern browser across desktops, tablets, and mobile devices. The entire process takes seconds.

SlimPDF is completely free with no hidden costs. There are no watermarks on your processed files, no daily limits on how many files you can process, and no premium tier locking features behind a paywall. We sustain the service through unobtrusive advertisements and keep the tools fast, reliable, and accessible to everyone around the world.
