The wider network
Beyond the tools
Separate sites built on the same idea: useful, quick, and free to open.
One page instead of 25 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 25 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 medical imaging, the free DICOM web viewer opens CT, MRI, X-ray and ultrasound DICOM files in the browser. Images are processed locally with no upload, which keeps patient data on your own device, and a free API lets developers embed the viewer in their own portals.
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.

Which 3D file formats does the online 3D viewer support?

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?

Yes. Every tool, including the PDF editor, the DICOM viewer and the 3D model viewer, is built to work on mobile browsers as well as desktop.
Is there a file size limit?
