How to Reduce Image Size for Email Attachments
Email limits apply to the whole encoded message, so attachments can exceed the provider limit sooner than expected. Reducing image dimensions and quality makes delivery faster for both sender and recipient.

Check what the recipient needs
A photo intended for on-screen review rarely needs the full resolution produced by a modern camera. Keep the original separately, then prepare a smaller sharing copy. If the recipient needs printing or detailed editing, use a less aggressive setting or a file-transfer method.
Compress and inspect the image
Select the image in BrowserCompress, start near 80% quality and inspect important details. Reduce the setting gradually until the attachment fits comfortably. The image stays in your browser rather than being uploaded to a compression provider.
Choose a compatible format
JPEG is the safest choice for ordinary photos and broad email compatibility. PNG is useful for screenshots and transparency but may be larger. WebP can be smaller, though you should confirm the recipient can open it in their normal workflow.
Send multiple photos efficiently
Compress each image and check the combined total before attaching them. Remember that email encoding adds overhead. For a large collection, consider a trusted sharing channel rather than forcing every image into one message.
