Understand first, then process
Each guide records a specific task, settings, input and actual output, with original downloadable examples to help you verify results and judge limitations.
Upload troubleshooting
Compare the receiving platform requirements with the actual image. Separate file size, pixel dimensions and true format to avoid repeated blind compression.
See the workflow and examples →Failure case study
Quality is not a compression ratio. Re-encode an already compressed scan to see why size increases and when to keep the original.
See the workflow and examples →Printing and layout
Dividing an A4 page into four produces pages about 105×148.5 millimeters each. Use the four-region example to distinguish splitting, enlargement and print layout.
See the workflow and examples →Practical test
Two one-page A4 files can have very different internal structures. Compare compression on two original examples before deciding to lower quality further.

Reproduce target-size compression on an office image containing small text and texture, then check format, pixel dimensions and readability.

One PDF can contain both text and scanned pages. Inspect the mixed two-page example page by page before applying OCR to the entire file.

Practice page organization with clearly marked A, B, C and D pages, then verify every operation in the exported file.
