Resize Before Sending
Phone photos can be several megabytes each. If the recipient only needs to view the image, resize it before attaching. A width around 1200 to 1600 pixels is often enough for general email review.
Choose The Right Format
Use JPG for regular photos and PNG for screenshots, logos, or images with transparency. WebP can be efficient, but some email workflows and older systems may not handle it as reliably as JPG or PNG.
Compress With Care
Compression should reduce file size without making text or important details unreadable. For document photos, check names, numbers, and signatures before sending.
Name Attachments Clearly
Descriptive filenames help recipients understand the attachment before opening it. Use names such as receipt-hotel-may.jpg or product-front-view.jpg instead of random camera names.
Recommended Email Workflow
Start by deciding whether the recipient needs an image for viewing, printing, or editing. Viewing copies can usually be smaller, while print or design files may need more pixels and less compression. Create a separate email-ready folder so the originals stay untouched. Resize the image first, then compress it, then open the exported copy before attaching it.
Attachment Size Targets
For ordinary email, aim for a few hundred kilobytes per image when possible. If you are sending five or ten photos, the total message size matters more than any single file. Some corporate inboxes reject large attachments, and mobile recipients may wait on slow networks. When images are still too heavy after resizing, send fewer files per message or use a shared drive link controlled by you.
Quality Checks Before Sending
Inspect text, labels, faces, receipts, and product details at normal viewing size. If the image documents damage, identity, expenses, or a customer issue, clarity matters more than the smallest file size. Keep filenames descriptive, avoid sending the only original, and include a short note explaining what each attachment shows.
