About 28tools
Free, private, and powerful browser-based tools for everyone. No uploads, no accounts — just results.
Privacy-First Tools for Everyone
We built 28tools because we believe that editing an image or working with a PDF shouldn't require uploading your files to someone else's server. Your files are yours — they should stay on your device.
Every tool on 28tools runs entirely in your browser using cutting-edge web technologies like the HTML5 Canvas API, File API, and WebAssembly. Nothing is ever sent over the network. Not a single byte.
And it's all completely free — no subscriptions, no watermarks, no hidden limits. Just open a tool and get to work.
Our Core Values
Simple principles that guide every tool we build and every decision we make.
Privacy by Default
Your files never leave your browser. We don't collect, store, or process any user data. There are no servers receiving your images or PDFs — ever.
Forever Free
All 42 tools are and will remain completely free. No freemium tricks, no watermarks, no file size caps, no daily limits. Full functionality, always.
Speed & Performance
By processing locally on your device, our tools are often faster than cloud-based alternatives. No upload wait times, no queue — instant results.
Accessibility
We build with accessibility in mind — proper ARIA labels, keyboard navigation, high-contrast support, and screen reader compatibility across all tools.
Works Everywhere
Whether you're on a phone, tablet, or desktop — every tool is fully responsive and touch-friendly. No app download required.
Open & Honest
No dark patterns, no surprise charges, no data harvesting. What you see is what you get. We believe in transparency in everything we do.

Powered by Modern Web APIs
28tools leverages the latest browser capabilities to deliver desktop-class functionality without any server-side code.
HTML5 Canvas API
All image processing — compression, cropping, filters, watermarking — is done via the Canvas API. No plugins, pure web standards.
File & Blob API
Files are read locally using the File API and processed as Blobs. Generated files are downloaded directly to your device — never sent anywhere.
WebAssembly (PDF)
PDF operations use PDF.js and pdf-lib — WebAssembly-powered libraries that run entirely in your browser, enabling professional PDF manipulation.
JSZip for Batching
When processing multiple files, JSZip packages your results into a single downloadable ZIP — instantly, without any server involvement.
