Online File Viewers

Open files your computer cannot: CAD models, 3D prints, e-books, design files, iPhone photos and saved emails. Free, private, nothing to install.

3D & CAD

STEPSTEP File ViewerOpen a .step or .stp CAD model and inspect it in 3D: rotate, zoom, see every part and the overall size. No CAD software needed.STLSTL ViewerPreview a 3D-printing model in seconds: open the STL, spin it around, check its size and mesh, then send it to the slicer.OBJOBJ ViewerLook inside a Wavefront .obj model with its materials and textures, straight in the browser, without opening Blender or Maya.GLBGLB ViewerCheck a .glb or .gltf model with its PBR materials and textures before you put it on a website, in AR or in a game.

Ebooks

EPUBEPUB ReaderRead any DRM-free EPUB book online: open the file and start reading with contents, larger text and a night theme. Nothing to install.

Images & design

AIAI File ViewerView an Adobe Illustrator .ai file without Illustrator. See the artwork sharply at any zoom, page through artboards and save a PNG.PSDPSD ViewerOpen a Photoshop .psd file online and see the finished image, zoom in to the pixel and browse the list of layers without Photoshop.HEICHEIC ViewerOpen iPhone HEIC photos on any Windows PC in a few seconds. No Microsoft Store extensions, no codecs, nothing to install.TIFFTIFF ViewerOpen .tiff and .tif files in the browser, page through multi-page scans and faxes, and zoom in to read every detail.

Email

EMLEML ViewerOpen a saved .eml email without Outlook or a mail app: read the formatted message, check who sent it and save its attachments.

Every one of these viewers opens the file directly in your browser. There is no upload queue and no account: the file is read on your own device, so models under NDA, client designs, personal photos and private emails stay with you.

They are built for the moments when the right program is missing: a STEP model from a supplier but no CAD, a PSD from a designer but no Photoshop, an iPhone photo on a Windows PC, or an e-book on a work laptop. When you need the file in another format, each viewer links to the matching converter.

Frequently asked questions

Are the file viewers free?

Yes. All viewers are free, with no sign-up, no watermark and no limit on the number of files.

Do my files get uploaded?

No. Files are opened and rendered in your browser, on your device. They are never sent to our server.

Do the viewers work on phones?

Yes. They work in modern browsers on Android and iPhone. Very large 3D models or images may need more memory than a phone has.
