About . v5.1

Built for teams that still ship serious Web Forms applications.

AjaxUploader is a 20-year-old upload-control product line that just shipped its most modern release yet. v5.1 brings direct-to-cloud uploads (S3 / Azure / GCS), encryption-at-rest, offline-mode queueing, and cloud-source pickers (Drive / Dropbox / OneDrive / Box) to the Web Forms world - without making you rewrite a single .aspx page.

15,000+ licensed teams in more than 60 countries. Built and maintained by Richscripts in Aurora, Ontario, Canada.

What we focus on

Depth over breadth in a single problem domain.

Web Forms specialization

Built for the ASP.NET Web Forms page lifecycle, server events, and ViewState model - not a generic JavaScript widget bolted onto a .aspx page. Drop <au:AjaxFileUpload /> in, wire OnFileUploaded, ship.

Modern transport stack

7 strategies in 5.1: classic, chunked, direct-to-S3, direct-to-Azure, direct-to-GCS, tus 1.0, and server-side URL import. Pick per-page or per-file. Bytes can skip IIS entirely.

Security & compliance built-in

Client-side AES-GCM encryption-at-rest, virus-scan hook with quarantine, antiforgery integration, role-based gating, and rate-limiting demos - ready for HIPAA / GDPR-adjacent workflows.

Long-term product maintenance

Shipping since 2003 with regular major upgrades. The CuteWebUI compatibility shim still keeps 4.x pages compiling on 5.1 with zero edits.
