Compression level
Pages are re-rendered as optimized images, so text will no longer be selectable in the compressed file.
Email providers cap attachment sizes, upload forms reject files over a certain limit, and large PDFs are slow to send over a weak connection. Compressing brings a bulky scanned document or image-heavy report down to a size that's easy to share, without needing a different file format.
No. Compression re-renders each page as an optimized image to shrink file size, so text in the compressed file is no longer selectable or searchable.
Medium works well for most everyday sharing. Choose Low if the PDF contains detailed images you want to preserve, or High when you need the smallest possible file for a strict size limit.
There's no fixed limit, though very large PDFs depend on your device's available memory since everything processes in your browser.
Yes, but each additional compression pass reduces image quality further. It's best to start from the original file and choose the right level the first time.
