About ToolNest

ToolNest is a collection of 38 free online tools for working with images, PDFs, code and everyday calculations — built on one simple principle: your files should never leave your device.

Why we're different

Most online tool sites upload your files to their servers for processing. That means your photos, bank statements, contracts and ID documents sit on someone else's computer — even if only briefly. ToolNest works differently: every tool runs entirely in your web browser using modern technologies like the Canvas API and WebAssembly. Nothing is uploaded, ever. That's why our tools are also faster — there's no upload wait and no server queue.

Genuinely free

Every tool is fully functional and free: no accounts, no trial limits, no watermarks, no "premium" locks on basic features. The site is supported by advertising, which lets us keep everything free for everyone.

What we offer

• Image tools — resize, compress, convert, crop, passport photos and AI background removal
• PDF tools — merge, split, compress, convert and watermark
• Developer tools — JSON, Base64, UUID, JWT, regex, timestamps
• Calculators & generators — EMI, GST, salary, age, QR codes, invoices, resumes
