Email attachments bounce, upload forms reject anything over a few megabytes and shared drives fill up quickly. Compressing a file is usually the fastest way past all three problems. This tool reduces the size of PDFs, documents and other common formats while keeping them readable, and lets you choose how aggressive the compression should be.
It depends on what is inside. Files with large photos or scanned pages shrink the most, while plain text files are already compact.
At normal settings the difference is hard to notice. Stronger settings trade some image sharpness for a much smaller file.
Common office and document formats are supported, including PDF files and the usual word processor and spreadsheet formats.
Everyday documents are handled comfortably. Extremely large files may take longer or need to be split first.
