Frequently asked questions
Will resizing reduce the file size?
Yes. Halving the width and height reduces the number of pixels by 75%, and the file shrinks accordingly.
What size should a photo be for email?
Around 1600 px on the long side is plenty for viewing on any screen and keeps attachments small.
Can I resize many JPGs at once?
Yes, with the bulk image resizer — all photos are processed on your device and downloaded as a ZIP.
Are my images uploaded to a server?
No. This tool runs entirely in your browser using WebAssembly. Your images never leave your device, and nothing is stored.
