Editors & studiosthe flagships

3D CAD + BIM

3D modelling, BIM import and simulation

Model with primitives and sketches, or import a model — IFC from Revit, SAF from SCIA, STEP and STL — and simulate: strength with finite elements, air in the wind tunnel and water that falls and spreads.

PDF editor

Edit & annotate PDF

Text, shapes, highlights, comments, page ordering, bookmarks and merging — like PDF-XChange, but in your browser.

Image editor

Photo editor with layers

Layers, selections, brush, blend modes and filters — the Photoshop feel with no install and no upload.

Video editor

Video editing with a timeline

Media bin, multiple tracks, cut & trim, titles and effects laid out like Premiere Pro — export to video.

E-signature

Get a PDF signed

Send a document out for signature with audit trail, certificate and verification page — the DocuSign alternative.

Viewer

View files

Open over 40 file types — PDF, Office, photo, video, IFC/STEP and 3D — without installing anything.

Merge & organize

Combine several PDFs and drag whole files or single pages into the right order. Rotate or delete whatever you don't need.

Split PDF

Extract pages from a PDF, or split the file into separate one-page documents.

Turn every page into a JPG image, delivered as a zip download.

JPG to PDF

Bundle images (JPG/PNG/WebP) into one tidy PDF document.

Watermark & letterhead
