Paper SwitchReduce PDF size by removing unused and duplicate data and compressing internal streams. Text, vectors and image resolution are retained.
No image downscaling or lossy image re-encoding. PDF pages are not flattened into pictures.
This preview shows only the first page. Download and review the full document before sharing.
Images in many PDFs are already compressed. This tool prioritizes quality and does not force a target size by reducing resolution or image quality.
One PDF up to 50 MB and 100 pages. Encrypted, digitally signed and damaged PDFs are not supported. Keep your original file.
Selected files are processed in your browser. Download the results before closing this page.
Useful after merging PDFs or preparing a document for an attachment size limit. The amount saved depends on the source PDF.
This tool reorganizes PDF data without lowering image resolution. Repeated or uncompressed data may shrink; already compressed scans may change very little. It does not promise a target size. If the new file is not smaller, the original is returned.
Compare the page count, page order and readability with the original. Try selecting text and opening any important links. Signed and password-protected PDFs are not supported; use an unsigned, unprotected copy only if you have permission.
A three-page workshop plan with a schedule, checklist and budget. Compare the first-page excerpts below: the words and table stay the same after compression.
This example was saved without compression. Already compressed files or scanned photos may shrink less.
Use this quality-first mode for reports with small text or diagrams. It does not lower image resolution or turn pages into pictures. Check the result size: if no space is saved, the download is the unchanged original.
A scanned PDF may contain already compressed JPEGs, so lossless optimization can save very little. Do not expect a guaranteed 1 MB result. If an attachment still exceeds its limit, split the document or remove unnecessary pages. Signed and encrypted documents are excluded.
