Mergy PDF Compress for Gmail

Compresses PDF attachments in Gmail on your computer before they upload.

Make PDF attachments in Gmail smaller, without leaving Gmail. Mergy PDF Compress shrinks PDF attachments right inside Gmail, on your computer, before they upload. Scans and photo-heavy PDFs often come out much smaller, so they send faster and take less space in everyone's inbox. • Works with Gmail's paperclip, drag and drop, and paste. • Compresses automatically when it saves at least 1 MB or halves the file. Otherwise the original is attached. • Every PDF attachment shows its size and quality. Switch between Smallest, Balanced, High quality and Original at any time. • Signed PDFs and fillable forms are attached unchanged by default. • PDFs over Gmail's 25 MB attachment limit are always compressed, so most of them still fit as regular attachments. Private by design: compression runs inside Chrome with WebAssembly. Your PDFs are never uploaded anywhere except to Gmail itself, and the extension collects no data. Free, with no account and no limits. Made by the team behind PDF Mergy (https://pdfmergy.app).
