Compress PDF
Shrink large PDFs so they're easy to email, upload, or store. Pick a compression level, and each page is re-rendered and optimized right in your browser — no file is ever uploaded, there's no watermark, and there's no daily limit like Smallpdf or iLovePDF. Works best on scanned or image-heavy PDFs.
