Compress image for Cold Outreach Email
Cold email deliverability suffers with heavy attachments. Keep images tiny.
Your images stay on your device. Nothing is uploaded.
Cold outreach and sales emails route through SMTP providers (Instantly, Smartlead, Woodpecker, Reply.io). Heavy attachments trigger spam filters more aggressively for cold email than for warm relationships. Landing every image under 100 KB minimises the deliverability hit.
This preset produces an 800 px JPEG at quality 78 — deliverability-safe.

Frequently asked questions
- What's the attachment size limit for Cold outreach email?
- Cold outreach email caps attachments at the size the preset on this page targets. Anything above the cap either gets rejected or gets converted to a link-share fallback (like Gmail's Drive attachment).
- Why compress before attaching to Cold outreach email?
- Recipients may be on slow mobile connections, and their servers may enforce lower caps than yours. Compressing before send maximises deliverability and speeds up download for recipients on mobile.
- Does Cold outreach email compress images automatically?
- Cold outreach email does not re-compress attachments the same way social media platforms do — what you send is what the recipient receives. So the size at send equals the size at receive.
- What format is best for Cold outreach email?
- JPEG is the safest universal choice for email attachments — every email client can preview it inline. WebP support varies (Outlook desktop can't preview WebP), so JPEG remains the default.
- Is my image uploaded to a server?
- No. Compression runs entirely in your browser. Only when you attach the compressed result to your email does it leave your device.
