3DPEA

3DPEA is a web-based utility that provides a wide array of free conversion tools, primarily focused on transforming 2D images into 3D printable models and converting between various file formats. It lets you upload a PNG or JPG image and convert it into an STL or OBJ file suitable for 3D printing. The platform also handles conversions between numerous other 3D, image, and PDF formats, and includes viewers to inspect files without dedicated software.

The tool works entirely in your browser. You simply select a tool, upload your file, and the conversion happens online. It supports a massive range of formats, from common ones like JPG and STL to more specialized types like DDS, HEIC, 3MF, and STEP. Beyond conversions, it offers utilities for merging image files, flattening PDFs, a 3D logo maker, and even a G-code simulator for 3D printing enthusiasts.

This toolkit is ideal for 3D printing hobbyists who need to create prints from images, digital designers working with multiple file types, and anyone who frequently needs to convert or view files without installing specialized software. It's perfect for quickly turning a logo into a 3D model, inspecting a CAD file sent by a colleague, or converting a batch of images into a single PDF.
