One range applies to each file
The page range is evaluated independently for every PDF. A range that exceeds any input document fails rather than silently skipping pages. Leave it empty to include all pages within the stated limits.
Use an independent reader
Open the exported file in a TIFF-capable viewer and check its page count, first and last page, orientation and resolution metadata. Some ordinary image viewers display only the first TIFF page.
Keep a repeatable record
The downloadable JSON report records file order and selected settings. Store it with the output when a later conversion needs to match this batch.
Verify the complete delivered file
Use a short PDF with visibly different page numbers for your first test. Select a range such as 2-4 and export it as TIFF. The resulting image should contain three frames representing those source pages in order. An application that only displays frame one is insufficient for verifying the full result; use its page or frame navigation controls.
When supplying several PDFs, inspect the single combined TIFF and use the batch-order table to match each file to its first output frame. The workbench processes bounded batches, but limits also apply to total rendered pixels and output size. A batch with several small documents can be more demanding than a single text-heavy PDF because scanned pages expand substantially when rendered as pixels.
Deflate reduces many document images without changing their decoded pixels, while uncompressed output can be easier for some older importers to accept. Try the recipient's preferred option first. If an application refuses the file, compare its documented compression, bit-depth and multi-page requirements instead of repeatedly changing DPI without identifying the actual incompatibility.
The built-in checks use page dimensions and output structure, and independent fixture tests read pixels back through another TIFF decoder. Your real destination remains the final compatibility test. Check a dense text page, the last frame and any transparency: PDF content is rendered against white, so transparency is deliberately flattened into the delivered document image.
