Beyond the tools
Separate sites built on the same idea: useful, quick, and free to open.
One page instead of 24 browser tabs
smartJOANS Smart Tools collects the small jobs that usually send you hunting for a sketchy download or a paywalled site. Students, freelancers and small businesses use the same 24 tools here — the difference is nobody is asked to sign up, and nothing is watermarked.
The free online PDF editor lets you add text, images, signatures and highlights to a PDF without installing software. Alongside it, the PDF suite covers the everyday six: merge, compress, crop, delete pages, PDF to image and PDF to EPUB. The AI humanizer rewrites stiff machine text into something a person would actually say. The QR generator produces clean codes with no logo stamped in the corner.
For makers, the online 3D viewer at artintentions.in opens 11 formats — STL, GLB, GLTF, FBX, OBJ, 3DS, DXF, PLY, DAE, 3MF and ZIP — straight in the browser, and 3D printing turns those files into physical parts.
On the money side there is a loan EMI calculator with a full amortisation view and a scientific calculator for everything else. Most tools do their work inside your browser, which is why they are fast and why your files stay on your machine.

Questions
Frequently asked
Short answers to what people ask most.
Are the smartTools tools free to use?
Yes. Every tool on smartTools is free — no sign-up, no watermark, no hidden fees and no trial limit.
Can I edit a PDF online for free?
Yes. The smartTools PDF Editor lets you add text, images, signatures and highlights to a PDF directly in your browser. It is free, needs no account and adds no watermark to the file you download.
Which 3D file formats does the online 3D viewer support?
The viewer at artintentions.in/open_your_models opens STL, GLB, GLTF, FBX, OBJ, 3DS, DXF, PLY, DAE, 3MF and ZIP archives that contain those files.
Can I order a 3D print from my own model?
Yes. Preview the model in the 3D viewer, then order a custom print through artintentions.in. Prototypes, miniatures, spare parts and gifts are all covered.
Do my files get uploaded to a server?
Most smartTools tools run entirely in your browser, so the file never leaves your device. Tools that do need the server delete the file straight after processing.
Do I need to create an account?
No account is needed anywhere on smartTools. Open a tool and start working.
Does smartTools work on a phone?
Yes. Every tool, including the PDF editor and the 3D model viewer, is built to work on mobile browsers as well as desktop.
Is there a file size limit?
Browser-based tools are limited only by your device memory, so a typical phone handles files up to a few hundred megabytes comfortably.
