How to compress a PDF without losing readability
PDF compression involves trade-offs. The goal is not simply the smallest possible file; it is a file that is small enough while remaining useful.
Practical workflow
Preserve the original first, especially when the document contains information that cannot easily be recreated.
Compression should create a working copy so you can compare the result without losing the source.
Inspect the parts of the document where quality matters most, such as small text, signatures, forms and evidence images.
Only replace the larger file when the smaller version still serves the purpose for which the PDF was created.
What quality means in a PDF
For a business document, quality may mean readable text and intact forms. For a scanned receipt, it may mean preserving small numbers. For a photograph-heavy document, it may mean retaining enough image detail.
There is no single compression setting that is correct for every PDF.
Avoid repeatedly compressing the same file
If a workflow repeatedly converts or recompresses already compressed images, visible artifacts can accumulate. Keep an untouched original and create a new working copy when you need a smaller version.
For important documents, compare small text, signatures, forms and any images that carry information.
Alyvero's current limitation
The MVP compressor uses PDF re-saving and object streams. It does not claim to deeply recompress every embedded image. Some PDFs may therefore become only slightly smaller or show no reduction.
That limitation is intentional: Alyvero reports the actual before-and-after result instead of promising a percentage that the file cannot deliver.
