Multi-file Upload for Workflows

Updates

January 12, 2026

We’ve improved the file upload widget so that you can now attach several documents, images, or evidence files at once.

You can upload 10 files at a time, up to a maximum of 100 files.
You can extract the text of your files for use in AI Tasks or Code Tasks.
You can also pass the comma-separated file URLs through native Process Street automations and Zapier.
With our API, you can append files when using the endpoint for multiple file uploads.

Original file upload fields will continue to allow only one file. Any new file upload fields you add going forward will support multiple files by default.

FAQ

How about the file upload limits; do they still remain the same as before? Are they cumulative?

The upload limits are the same as before, and they’re counted per file, not cumulative across multiple uploads.

Do the limits apply per uploaded file type?

The limits are enforced per file (so each uploaded file is evaluated on its own).

For text extraction, is it also per file? If I have 10 files, does each file get the 512KB plain text limit?

Technically, yes, extraction is per file. So each of your 10 files can be extracted up to the per-file extraction cap (e.g., 512KB plain text per file).

However: if you insert the extracted text as a variable, the platform may truncate the result because long text fields have a maximum size limit, even if the extraction itself was within the per-file limit.
