Compress PDF
Reduce PDF file size while optimizing quality.
Frequently Asked Questions
How does PDF compression work?
PDFtiny renders each page as a JPEG image and creates a new PDF from those images. Smaller output depends on the original document, selected quality, and resolution.
Is an exact target size guaranteed?
No. Target Size mode searches compression settings for a result near the requested limit. Some documents cannot reach a small target with readable output. Check the downloaded file size and page readability.
What changes in the compressed document?
Text becomes part of the page image and may no longer be searchable or selectable. Interactive forms, links, bookmarks, and digital signatures are not preserved by this image-based conversion. Keep your original PDF.
