Frequently Asked Questions
What is the maximum attachment size for email?
Gmail allows attachments up to 25MB per email. Outlook allows 20MB, and Yahoo Mail allows 25MB. However, the actual limit is lower because email encoding increases file size by about 33%. This means your actual attachment should be under 18-19MB to ensure delivery.
How do I compress photos to send by email?
Upload your photos to this free tool, set the quality to 60-75%, and limit the max width to 1200-1600 pixels. This typically reduces photos from several megabytes to under 500KB, making them easy to attach to any email without hitting size limits.
Does compressing images for email reduce quality?
At 70-75% quality, the compression is virtually invisible on screen. Email recipients view images on screens, not in print, so moderate compression is perfectly fine. The slight quality reduction is a worthwhile trade-off for reliable email delivery.
