About this image metadata editor
The image metadata editor adds or edits text metadata in PNG and JPEG files — fields such as a title, description, author, or comment. Rather than stripping data, this tool lets you set it, which is useful for labelling, crediting, or annotating an image.
It is handy for adding a copyright line, a caption, or an internal reference to a file before it goes into a library or out to a client. Saving re-encodes the image and writes the text fields you set; other embedded data such as camera EXIF is not carried over, so keep an original if you need it.
Common uses
- Add a copyright or author credit to a PNG or JPEG.
- Set a title, description, or comment on an image for a library or archive.
- Embed an internal reference or caption into an image file.
Helpful tips
- PNG and JPEG store text metadata differently, so the available fields vary by format.
- Metadata travels with the file, so avoid putting anything private into a public image.
- Keep an unedited copy in case a platform strips or rewrites metadata on upload.
How to use Image Metadata Editor
- Upload the image you want to process with Image Metadata Editor.
- Check the current dimensions, format, orientation, transparency, and file size before changing anything.
- Choose output settings based on the destination, such as web upload, email, social media, documentation, or archiving.
- Preview the result for visible quality, cropping, color changes, metadata, and final file size.
- Download the finished image and keep the original file until you confirm the exported version works where you need it.
Frequently asked questions
What metadata can I add to an image?
For PNG you can add named text fields such as title, description, author, or comment. For JPEG the values are written into a standard comment, since JPEG does not have those separate named fields.
Will the metadata survive uploading to a website?
Not always. Some platforms strip or rewrite metadata when processing uploads, so do not rely on it for critical information.
Is Image Metadata Editor free, and does it work on mobile?
Yes. Image Metadata Editor is free to use on JustBloc with no account or installation, and the page is designed to work on desktop, tablet, and mobile browsers.
