Aspose.PDF Cloud Go SDK helps you build PDF generator, annotator, and converter apps for the cloud, using the Go programming language. The SDK is available under the MIT license and is based on the Aspose.PDF REST API. You can enhance your Go code to access Acrobat files situated on cloud storage or create new cloud PDF pages. It also enables creation of PDF files by converting HTML, PCL, XPS, TIFF, JPEG, SVG, and XML formats into cloud‑based PDF documents. Your Go applications can work with various elements of Adobe Acrobat PDF documents, such as text box, checkbox, radio button, form fields, annotations, digital signatures, stamps, attachments, as well as OCR layers of cloud PDF files. The SDK enables downloading attachments from cloud‑based PDFs, extracting all images with default or specified sizes, and exporting data from PDF documents to other supported file formats—without installing any third‑party software.

Features

• Create new cloud‑based PDF pages and convert HTML, PCL, XPS, TIFF, JPEG, SVG, and XML to PDF.
• Access and modify text boxes, checkboxes, radio buttons, form fields, annotations, digital signatures, stamps, attachments, OCR layers.
• Download and manage attachments from cloud PDFs.
• Extract all images with default or specified sizes; export PDF data to supported formats.
• Add text or image headers and footers.
• Add text and image stamps; delete stamps by ID or remove all stamps from a page or entire document.
• Read document stamps.
• Add tables to documents; delete all tables from a page or entire document; read or delete tables by ID.
• Append multiple documents to an existing PDF.
• Set and get multiple annotation types including text, circle, polygon, polyline, line, square, free text, highlight, underline, squiggle, strikeout, caret, ink, link, popup, file attachment, sound, movie, screen, widget, watermark, TrapNet, printer mark, redaction, rubber stamp, and rich media annotations.
• Set annotation flags (visibility, print restriction, magnification restriction, rotation restriction, read‑only).
• Apply annotation states (marked, unmarked, accepted, rejected, canceled, completed, none).
• Modify stamp properties (opacity, rotation, alignment, indentation, zoom).
• Extract PDF images (GIF, JPEG, PNG, TIFF).
• Extract annotation types such as FileAttachment, screen, sound, and stamp.
• Convert to/from PDF using EPUB, HTML, LaTeX, MHT, PCL, DOC, MobiXML, PDF/A, PPTX, SVG, TIFF, XLS, XLSX, XML, XPS, PS, XSLFO, BMP, EMF, GIF, JPEG, PNG.
• Convert PDFs with XFA forms to PDF with AcroForm.
• Control Word conversion output via “Textbox” (layout‑preserving) or “Flow” (editable) mode.
• Set document access privileges (printing, degraded printing, content modification, copying, form filling, etc.).
• Optimize PDF documents by reusing page content, adjusting image compression, linking duplicate resource streams, removing unused objects or streams, and skipping embedded fonts.

Benefits

• Build cloud‑native PDF manipulation workflows in Go, without installing local PDF libraries.
• Full REST API support ensures reliable PDF generation, editing, annotation, conversion, and automation.
• Rich annotation, form‑field, and document‑structure editing tools for advanced document manipulation.
• Wide input/output format conversion enables seamless integration in cloud pipelines.
• Strong security: encryption, decryption, and access‑privilege control.
• Efficient extraction tools for images, attachments, and structured elements.
• Document optimization improves performance and reduces PDF size.
• Easy onboarding: only an Aspose Cloud account with App SID & Key is required.
