Convert with the Pdftools SDK
With the Pdftools SDK you can convert various file formats:
- Convert a PDF document to PDF/A
- Convert images to PDF
- Convert images to accessible PDF/A
- Convert a PDF document to image
Convert PDF to PDF/A
With the Pdftools SDK, you can convert PDF documents to PDF/A specification (PDF/A-1, PDF/A-2, PDF/A-3), including all conformance levels (B, A, and U). You can read encrypted documents, repair or recover corrupt data and objects. You can remove content and convert embedded and attached files.
| Input format | Output format |
|---|---|
| PDF 1.x, PDF 2.0 | PDF/A-1, PDF/A-2b, PDF/A-2a, PDF/A-2u, PDF/A-3b, PDF/A-3a, PDF/A-3u |
Input document processing
- Automatically determine optimal conformance based on input file (optional)
- Recover corrupt documents
- Repair corrupt data such as embedded font programs or images
- Repair metadata and make them consistent
Color management and fonts
- Make color spaces device-independent, e.g. by embedding ICC profile or setting an output intent
- Manage colorants (PDF/A-2 and later)
- Embed and subset fonts
Conversion process
- Control the conversion process with pre- and post-validation, conversion reports, and application log files
- Remove transparency (PDF/A-1 only)
- Remove malicious content such as attached files (PDF/A-1 and PDF/A-2) and JavaScript actions
- Remove multimedia content such as video and sound
- Convert embedded and attached files (PDF/A-2 and later)

Convert PDFs to images
Create single-page and multi-page image files and rasterized PDF documents from PDF documents. Specify how PDFs are converted to images, choosing the resolution, quality in lossy image compression, as well as the color space and depth to be used. Convert PDFs to TIFF-F suitable for fax transmission using the Fax conversion profile.
| Input | Output |
|---|---|
| PDF 1.x, PDF 2.0, PDF/A-1, PDF/A-2, PDF/A-3 | TIFF, PNG, JPEG |
Image processing
- Set resolution (DPI)
- Add dithering: choose Floyd Steinberg, Halftone Block, Halftone Continuous, or Atkinson algorithms
- Set image filters
- Set TIFF file compression
- Set the quality of lossy image compression
Color management
- Set color depth
- Set color space
- Set bit filling order for fax files
Page layout
- Define page dimensions in points or pixels
- Set rotation: force portrait or landscape or inherit rotation from original document
- Add watermark images

Convert images to PDF
Convert one or more single-page or multi-page raster images into an output PDF document. Use default image to PDF conversion profiles to automatically process image conversion. Specify how the images are processed, selecting compression level, image quality, and resolution. Choose the formatting of the output document, including page size, area, scaling, and image position and orientation. Determine the conformance level of the output PDF document, and set additional document settings such as attributes, permissions, alternative text.
| Input | Output |
|---|---|
| BMP, GIF, JBIG2, JPEG, JPEG2000, JPEG-LS, PBM, PNG, TIFF, LZW, CCITT | PDF 1.x, PDF 2.0, PDF/A-1, PF/A-1b, PDF/A-2, PDF/A-2b, PDF/A-2u, PDF/A-3, PDF/A-3b, PDF/A-3u |
Image processing
- Select image compression, depending on the image type
- Select image quality for lossy compression
- Set standard resolution (DPI / X and Y coordinates)
- Choose optional JPEG image recompression
- Support for image masks and mixed raster content (MRC)
Page layout
- Select PDF page size or determine automatically
- Select page area
- Set scaling
- Set image position
- Set image orientation (portrait or landscape)
PDF document settings
- Set encryption and user access permissions
- Set document attributes
- Select and embed ICC color profiles
- Embed XMP metadata
