What PDF compression can safely do

Compress PDF helps reduce file size by rebuilding the document and removing some unnecessary overhead. This is useful before emailing a PDF or uploading it to a portal with a file size limit.

Some PDFs shrink more than others. Text-based PDFs often compress differently from scanned documents, because scans store each page as an image.

Check quality before sharing

After compression, open the new file and inspect small text, signatures, stamps, charts, and images. A smaller file is only useful if the document remains readable.

Keep your original PDF until the recipient accepts the compressed version. PDFMood processes locally in your browser and does not replace your source document.
