About · v5.2

Built for long-lived Web Forms applications.

AjaxUploader is a long-running upload-control product line maintained for teams that still depend on ASP.NET Web Forms. v5.2 brings the self-hosted Companion broker that keeps cloud tokens server-side, 6 cloud sources, headless hooks for React, Vue, Svelte, and Angular, and a content-aware image editor with AVIF/WebP output to the Web Forms world without forcing a rewrite of existing .aspx pages.

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

What we focus on

Focused depth for one demanding 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 5.2: 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 for HIPAA- and GDPR-sensitive workflows.

Long-term product maintenance

Shipping since 2003 with regular major upgrades. The CuteWebUI compatibility shim still keeps 4.x pages compiling on 5.2 with zero edits.
