About this tool
Shrink oversized PDFs so they fit email attachment limits and upload faster, while keeping text and layout intact. Compression recompresses embedded images and optimizes the file structure directly in your browser — no waiting for a server, no upload queue, and no file size limit imposed by a subscription tier.
Will compressing reduce text quality?
No. Text and vector content stay sharp — compression mainly targets embedded images and redundant file data.
How much smaller will my file get?
It depends on the PDF’s contents. Image-heavy PDFs typically shrink the most; text-only PDFs are already small and may see little change.
Is my PDF uploaded to a server?
No, compression runs fully client-side in your browser.
