Check the result, not just the file size

Open the original and an output at the same zoom. Compare small numbers, fine lines and all three pages. Use the clearer version when it fits your upload limit. Keep your original until you have checked the downloaded file.

These are actual outputs from WolfPDF on the date above, not a promise that every document will reach the same size. The source is deliberately image-heavy. PDFs that are already compressed, digitally signed, or contain selectable text can behave differently. Compression does not add OCR or prove that another website will accept a file.

WolfPDF processes uploads on its servers. This example is free to inspect and does not require an account. Read how files are handled.
