Editing metadata
All editing happens inline, in the metadata panel. There is no separate edit mode, and no dialog for every field.
How editing works
- Select a file (or several). Its metadata fills the right-hand panel, grouped into sections.
- Hover a field. A pencil icon appears on the ones you can edit. Fields without a pencil are read-only — see Read-only fields.
- Click it. The value turns into the right editor for its type: a date picker for dates, a coordinate input for GPS, chips for keywords, a number field with limits for ratings.
- Change the value. Validation runs as you type. Enter confirms, Escape cancels.
- The field is now a pending change — highlighted, counted in the toolbar, and not yet written to disk.
- Save or discard. Ctrl+S writes everything pending; Discard throws it all away.
A highlighted field means "this differs from what's on disk". If nothing is highlighted, the file on disk matches what you're looking at. That rule holds everywhere in the application.
Field editors
Each field type gets an editor built for it, which is what keeps invalid values out of your files.
| Editor | Used for | Behaviour |
|---|---|---|
| Date | DateTimeOriginal, CreateDate, ModifyDate | Calendar plus time input, to the second. Also offers offset mode. |
| GPS | Latitude, longitude, altitude | Range-checked numeric input, with a map picker and place search. |
| Text | Title, copyright, artist, make, model | Single-line input, rejects empty and malformed values. |
| Text area | Description, comment, lyrics | Multi-line editing that preserves line breaks. |
| Number | Rating, ISO, track, disc, BPM | Enforces the minimum and maximum for that field — a rating cannot leave 0–5. |
| Keywords | Keywords and other list fields | Chip editor: type to add, click to remove, order preserved. |
| Read-only | Duration, codec, bitrate, dimensions | Displayed for reference; cannot be edited because it describes the data itself. |

More than forty fields, listed in full in the field reference — standard tags, extended tags such as BPM and initial key, credits, ReplayGain values, and lyrics.
Editing several files at once
Select multiple files and the metadata panel shows the fields they have in common.
- Where every selected file agrees, you see the shared value.
- Where they differ, you see
(Mixed values). - Editing any field asks you to confirm before applying it to all of them, and tells you how many files that is.
- Fields you don't touch keep their per-file differences. Editing
Copyrightacross a selection does not flatten everything else.
Applying one value across an entire selection is a Pro capability. In Free, editing works one file at a time. See pricing.
Undo and redo
Every edit is a command on a history stack, so Ctrl+Z steps back and Ctrl+Shift+Z steps forward — including bulk operations like a date offset, which undo as a single action rather than four hundred separate ones. History holds the last fifty operations and persists until you clear it.
Read-only fields
Some fields can't be edited, and the reason is usually one of these:
- It describes the data, not the file's story — duration, codec, bitrate, sample rate, image dimensions. Changing the number wouldn't change the reality.
- The format doesn't support writing it — some containers accept far fewer tags than others.
- It isn't in the editable set — EveryMark ships with a defined list of editable fields, deliberately, so that a stray click can't write something exotic into a file.
Everything readable is still shown, and the raw JSON view gives you the complete tag dump when you need to confirm what's actually in there.
