Microstock file formats for uploading vector illustrations

Every Microstock agency use a bit different upload system – specially for vector images. On some sites you need JPG preview with EPS file with same filename, on others you need to have it packed in a ZIP file, somewhere you need big JPG preview and some sites needs just EPS. Here is a simple overview of all bigger microstock sites with their file format requirements for vector illustrations.


  • EPS + JPG with same filename

  • EPS + JPG packed in one ZIP file
  • EPS format 8 or 10, AI

My recomendations

I’m creating the JPG preview of the size around 15 Mpx (some explanations is here: What is the best vector image size for selling in microstock?) it is a little big, but it can be used and sold as a raster / bitmap illustration on the sites, that don’t support vectors, or for users, that don’t know how to vork with vectors and preffer big JPGs.


  1. What is the best document size to work with, the size that can fit all microstock agencies ,without finetuning sizes for each other???

    Thank you

  2. Orson,

    Do I need to make my image exactly 4000×4000???? Most of my images are around

    Which Zip program should I use to zip my files?? Can you recommend the Zip program that works fine on Fotolia, canstock and depositphotos and similar sites??

    I am using Stuff it for mac and expresszip in PC usually in my job routines.
    In this case, I am not sure which Zip program to use because it may work for this but not others.

    Thank you again for yr help.

  3. Hi David,
    no, you don’t need to use exactly 4000×4000.
    4000×2000 = 8 Mpx, 4000×3600 = 14.4 Mpx
    It is quite enough.

    I don’t work on mac, so I can’t recommend you any. The result must be just .zip file. So try, what you have and you will see.

  4. some of the sites I visited require IPTC metadata along with the images sent to them. I applied the info in Adobe Illustrator and clicked „ok“ and then saved the work but the data was blank when I opened the file to check it. Is this a common problem? Do you have any solutions? thanks.

  5. The IPTC metadata must be in the JPG file, not in the EPS or AI! I don’t know, how it works in Illustrator – probably you have to add those information first and then export the JPG. I use standalone freeware utility for adding IPTC to JPG files – PhotoStock the free version is good enough for it.
