Compress for email in seconds — no uploads, no accounts.
Most email providers cap attachments around 20–25 MB. High‑resolution images inside a PDF can push you past that limit fast.
Compression solves it by re‑encoding images while keeping text and layout crisp. The file size can drop by 50–80% with minimal visual change.
Open RadiantPDF’s compress tool, drop your file, and download the smaller version. Everything runs locally in your browser, so your file never leaves your device.
