PDF Compressor

Shrink a PDF by re-rendering each page as a compressed image — perfect for scanned documents, photo-heavy PDFs and email attachments that are too big to send. The file is processed entirely in your browser; nothing is uploaded.

Good to know

Compressed pages become images inside the new PDF, so text is no longer selectable or searchable and links/bookmarks are lost. Savings are biggest on scanned or image-heavy PDFs. A text-only PDF is already compact — it may barely shrink, and can even grow; if that happens we'll tell you and recommend keeping the original. Very long PDFs can take a while, especially on the Print preset — keep this tab open while it works.
