Frequently Asked Questions
Why do email attachments bounce or get blocked?
Most email providers (Gmail, Outlook, Apple Mail) enforce attachment limits between 10MB and 25MB, and corporate spam filters frequently block large image attachments. Keeping email photos under 500 KB ensures instant delivery and fast inbox loading.
What is the best image resolution for email?
A maximum width of 1200px is ideal for email newsletters and attachments. It looks crisp on Retina mobile screens while preventing bloated email message size.
Is it safe to compress confidential business photos here?
Yes! Image Well Done runs 100% locally in your browser memory. Your confidential contracts, receipts, and photos are never uploaded to any server.
