What is the maximum PDF size I can email?
Most email providers like Gmail, Outlook, and Yahoo restrict attachments to 20MB or 25MB. This tool intelligently compresses images and fonts so your file fits easily under that limit.
Will compressing ruin my document's text?
No. Our local WebAssembly compression targets embedded images (downsampling them to 144 DPI) and unused font data, leaving all vector text perfectly crisp and readable.
