Compress an image for email
Make photos small enough to email without hitting attachment limits — free, private, and processed on your device.
Camera photos are often several megabytes each, which quickly bumps into email attachment limits or makes messages slow to send and receive. Set a small target size — say 1MB or 500KB — and this tool compresses your photos so they attach and send easily.
You can compress a batch at once and download them together, all without uploading a thing, which keeps personal photos private.
