What's new in 5.2 New

Why upgrade?

  • Companion broker New in 5.2 - a self-hosted Node/Express OAuth and file-proxy broker (multipleupload/server/companion) that keeps provider client secrets and access tokens server-side, with proxy and server-to-destination transfer modes. Zero new dependencies.
  • 6 cloud sources New in 5.2 - Drive, Dropbox, OneDrive, Box (now first-class), Unsplash (search and import), and the Companion broker.
  • Headless framework hooks New in 5.2 - useUploader() for React and Vue, use:uploader for Svelte, UploaderService for Angular, for fully custom UI.
  • Content-aware image editor New in 5.2 - focal-point smart-crop, text and sticker overlays, filter presets, EXIF info panel, and AVIF/WebP output with a quality slider. Plus the IImageTransformer server-side extension point.
  • 7 transport strategies - single / chunked / s3 / azure / gcs / tus / urlImport, swappable via one Strategy option.
  • 4 cloud-source pickers - let users import from Google Drive, OneDrive, Dropbox, and Box without leaving your page.
  • Encryption-at-rest - AES-GCM-256 (Web Crypto) protects browser-side queued and resumed files; zero-knowledge upload to your storage.
  • Offline-first queueing - service worker persists the queue across tab close and network loss; resumes automatically on reconnect.
  • Cross-tab dashboard - coordinated upload state across browser tabs via BroadcastChannel.
  • Virus-scan hook - new /scan endpoint + OnFileUploaded integration for ClamAV, Defender, or any scanner CLI.
  • 28 built-in locales - includes RTL Arabic, Hebrew, and Persian.
  • Image pipeline - inline annotation, HEIC auto-decode, and 5 preset sizes ready to drop in.
  • PDF + video lightbox preview, composable UI primitives, and drag-to-reorder queue.
  • Pluggable provider interfaces - IS3Signer, IAzureSigner, IGcsSigner for clean server-side credential brokering.
  • Direct-to-cloud multipart - browser uploads straight to Amazon S3, MinIO, R2, B2, Azure Blob, or GCS via presigned URLs. Bytes bypass IIS entirely.
  • IndexedDB-backed resume - uploads survive tab crashes and page reloads; chunked, s3, azure, gcs, and tus strategies all rehydrate from the last completed part.
  • Full backward compatibility - CuteWebUI namespace shim keeps existing 4.x pages compiling unchanged.
  • Comprehensive class reference documentation.
Do I qualify for the upgrade price?

Yes, if you hold any valid AjaxUploader 4.x license. The upgrade price corresponds to your current license type.

Will my existing code still work?

Yes. AjaxUploader 5.2 ships the CuteWebUI compatibility namespace so existing 4.x code compiles without changes. See the migration guide for details.

Can I buy a new v5.2 license instead?

Yes. New licenses are available on the pricing page at full price if you prefer a fresh license.
