Choose a compression mode
Lossless and recommended modes focus on removing unnecessary data while preserving the PDF structure as much as possible. Strong and extreme compression may rebuild pages as images, greatly reducing size but removing selectable text, links, and form data.
Check before submitting
Before uploading to a government, tax, school, or recruitment site with a file-size limit, check both the output size and page quality. An already optimized PDF may become larger after compression; in that case, keep the original.
How the file is processed
PDF analysis and saving run in your browser. The document is not sent to toolmoa because no upload server or remote conversion API is used. Encrypted or damaged PDFs may not be processed successfully.
