ZANCTA documentation
Everything you need to know: what a tool accepts, what it produces, and how supported local processing behaves — written for the product you can use today.
In this guide
01
Tool collection
The tool collection is the current catalog. PDF workflows cover merge, split, compression, page rendering, image-to-PDF, and embedded-text extraction. Image workflows cover compression, conversion, resizing, metadata cleaning, and local English OCR.
02
Inputs and limits
Every tool page shows its accepted file type, maximum size, and batch limit. Most local PDF and image workflows use a 50 MB per-file boundary. OCR uses a 20 MB image boundary and supports JPG, PNG, and WebP. The displayed tool limit always takes precedence.
03
Processing and output
Implemented local tools process selected file bytes in the browser and generate outputs on-device. A tool may provide a download, copy action, preview, or all three depending on its purpose. Progress is tied to reported engine work where that is available.
04
OCR and PDF text
Image OCR uses bundled English assets in a browser Worker. PDF Text Extractor reads embedded text page by page from text-native PDFs. It does not turn scanned PDFs into text and reports an honest no-text state for image-only documents.
05
Accounts and subscriptions
Local tool use is available without an account. Accounts support authentication and entitlement records. Premium and payment behavior are presented on Pricing only when provider configuration makes those actions available.
