Our credit-based pricing model charges credits for every operation you perform on each page of your document. A "page credit" is consumed for every page in the file and for each operation applied to that page. This allows you to only pay for what you use, based on the number of pages and operations involved.

Each page of your document requires one credit per operation. For example:

• 1 page, 1 operation: If you convert a 1-page TIFF file to a PDF, you will use 1 credit

• 5 pages, 1 operation: If you convert a 5-page TIFF to a 5-page PDF, you will use 5 credits (1 credit for each page)

• 5 pages, 2 operations: If you convert a 5-page TIFF to a PDF and then optimize the PDF file, you will use 10 credits (5 pages x 2 operations)

Besides PDF to PDF/A conversions which are charged at 2 credits per action, all other operations are taking 1 credit.

An operation is any feature you apply to your document using the Pdftools SDK. This could include:

• Converting files (e.g., TIFF to PDF, PDF to image)

• Compressing and optimizing your PDFs

• Merging files or extracting pages

• Other SDK features such as signing, encrypting, or annotating PDFs.

Each time you apply an operation to one or more pages, credits will be used.

The number of credits you need depends on the number of pages and operations you perform. Use this formula:

Total Credits = (Number of Pages) x (Number of Operations)

Example:

• If you convert a 3-page TIFF into a PDF, you will need 3 credits

• If you convert that same 3-page PDF and then compress it, you will need 6 credits (3 pages x 2 operations)

PDF/A operations are 2 credits, example:

• If you convert a 3-page PDF into a PDF/A, you will need 6 credits

Credits are consumed based on how many operations you apply. For example:

• If you convert a 4-page PDF and then compress it, you will use 8 credits (4 pages x 2 operations)

• If you perform a third operation, such as adding a watermark, that will require 4 more credits (4 pages x 1 additional operation), totaling 12 credits
