Eagle to Fritzing


My self Mithun. I am working on a fritzing conversion project which is eagle pcb file to fritzing file.
I could convert the eagle pcb file to svg files which include breadboard, schematic& pcb. May i know how do i connect all these files to frizting and how do i connect them without any manual efforts( i mean creating connectors , metadata & selecting the graphics manually) to fritzing.
Also I am confused that what will be the output file.is it .fzpz file or .fzp file?

Good morning.
I guess your best choice is to build a very simple PCB in fritzing and save it. It will be a fzz file that you can open with your favourite file compresion software (i use 7zip)
There you will find several archives thay you can open with a text editor (i like notepad++)
The main problem i see here, is that depending the type of part (core or imported) fritzing will generate aditional archives or not. If you do a simple PCB with 2 resistors, there will be no aditional files, but if you use, i.e. a custom arduino module, you will have at least 3 aditional files for breadboard, schematic and PCB views.
Conections are made with labels IDs inside svgs. If you spend some time analyzing the files you will find correspondences quickly.

Good luck.

There already is such a program called Eagle2Fritzing. It requires that you have a development environment for Fritzing up and working to build Eagle2Fritzing. You then run Eagle2Frtizing against the .brd file and it will (with some work) generate a Fritzing part. The original code is on the Fritzing site, but you are probably better to use the fork on Adafruit as has been worked on more recently.

The part file itself will be .fzpz. That is actually a renamed .zip file which contains several .svg files and a single .fzp file. The .fzp file is the metadata.

For the details of what goes into the .fzp file, see “FZP Format” in Part File Format. Some is required, some optional.

Eagle2Fritzing can create functional fzpz files, but it is a good idea to do some testing. FritzingCheckPart is a python based tool that can also help verify some of the technical details.

If you are trying to convert an Eaglecad drawing to a Fritzing sketch, that is a (much) bigger job. All of the “parts” in the eagle document would need to be converted (or mapped) to Fritzing parts first, then combined back together into a .fzz file. .fzz is another .zip file containing the actual .fz sketch, plus all of the part information for anything that is not included in the core parts. I have not seen documentation for how a .fz file is put together. It (like .fzp) is an xml document, but the content structure seems to be only in the Fritzing code.

Thank You so much for the detailed reply

Thank You so much for the detailed reply.
I would like to ask one more query

After creating the fritzing file how do i create a separate tab for my company in fritzing software where anyone can use our company fritzing files?

For “anyone” to use it, a pull request will be needed for the core parts library repository, to add a company_name.fzb file with (optionally) an associated png icon files. See files in fritzing-parts/bins/more for samples.

For your own use, to create a bin for your self, the “Parts” window has a dropdown menu with an option to create a new bin. That bin can be exported. The exported bin could be published in the forum (or elsewhere) for anyone to download and import. To work, the parts in the bin also need to exist either in the core parts library, or loaded from fzpz files.

So the parts need to be created, added to a bin file, and either published or merged into the core parts. See downloading the Fritzing library from github and links from there for how AdaFruit has done it.

Not all of the company specific parts need to be in the fzb file. Parts in the same family can be used by adding any one of them to a sketch, then using inspector to switch to other parts in the same family. Assuming the parts have matching properties with different values.

Eagle2Fritzing only does about half the job, it requires a lot of (undocumented as far as I know) editing to get to a usable part. I’d suggest doing a first part and post the part (the .fzpz file) here and one or more of us will check it out for you. As well this part tutorial series may help since it points you at the part standards documentation as well as modifies the part via editing the files (which is required to use Eagle2Fritzing successfully.)


Hello Merlin,

I am almost created my fzb file which includes 5 projects. Now i want to publish in to fritzing so that any outsider can download our fritzing files.
May i know the standard flow or process how to do that?
I also want to add my company logo in fritzing

Please help me to add our fritzing files with fritzing.

If you publish the .fzpz files for your 5 projects one of us will look them over and point out problems. When the files are uploaded here they are available to the general public for download. To get your parts (and your bin) added to core parts in Fritzing you need to make a pull request against the frtizing-parts repository on github at which point if the parts meet the QA standards they will be added to core parts.


I have not explored this, but I believe it is also possible to upload a .fzb file that others can download and import to get the whole bin in their local environment. That is one of the ways to use the Adafruit parts.

As Peter says, in all cases, the parts should be run through some quality control before being widely distributed. There are several situations where parts look good in Fritzing, seem to work just fine, but then break in specific cases. A common problem is not exporting properly as an svg file.
