Frequently Asked Questions
Common questions about the free online image metadata editor.
It reads and rewrites the JPEG comment segment and the simple Exif text fields: image
description, artist and copyright.
No. It rewrites comment segments and simple Exif text, but it cannot rewrite every
proprietary field, maker note or encrypted block.
Exif text fields have a fixed size in the file, so a new value must fit in the space the
original field already occupies.
Existing comment segments are removed and one new comment segment with your text is written
directly after the start of image marker.
Yes. The rewrite happens in memory and the original file on your device is never modified, so
you can always start again.
No. The bytes are read with the browser file reader and the new file is built locally, so
nothing leaves your device.
JPEG files only, because the comment and APP1 segments are specific to that format. PNG and
WebP files use different structures.
Yes. The rewritten segments follow the JPEG and Exif specifications, so file managers and
photo editors can read the new text.
No. This editor only reports and rewrites the comment and simple text fields, so other Exif
blocks such as GPS are left untouched.
Yes. The editor works in any modern mobile browser, although typing long comment text is
easier on a desktop keyboard.
