Every file.
Every tag.
One window.

EveryMark reads and writes the metadata inside your photos, videos, and music — the capture dates, the coordinates, the artist credits, the copyright lines. Thousands of files at a time, on your own machine.

Free core app. Pro adds batch editing, online tag lookup, presets, and backups.

The problem

Metadata rots quietly, and every app downstream trusts it anyway.

Your library app, your media server, your backup tool — none of them read the photo. They read the tags. When the tags are wrong, everything built on top of them is wrong too.

Cameras lie about time

A clock that was never set. A timezone you crossed at 2am. A battery that died and reset the body to 2010. Every frame from that trip is filed under the wrong day, forever, in every app you own.

Rippers guessed

A disc ripped in 2006 by a tool that matched the wrong release. Now half a discography has no album artist, three spellings of the same band, and compilations that scatter across your library.

Scrapers gave up

A file named badly enough that your media server filled in a different film — or nothing at all. Renaming it doesn't help. The fix has to go inside the file, where the next scraper will actually look.

What it does

A metadata editor that treats a library as the unit of work.

Most tools edit one file. EveryMark loads a folder tree, shows you what every file claims about itself, and lets you correct all of it in one pass — with a backup taken before anything is written.

Full feature breakdown →

01

Read what is actually in the file

Every EXIF, IPTC, XMP, and ID3 tag, grouped into readable sections — plus a raw JSON view when you need the truth without the formatting.

02

Edit in place, review before writing

Click a field, change it, keep going. Pending edits stay highlighted until you save, so you can see the whole change set before it touches disk.

03

Shift dates across a whole shoot

Enter an offset in days, hours, minutes, or seconds. Preview the result. Apply it to four hundred files at once — the relative order stays intact.

04

Set locations on a real map

Click a point, or search a place by name. Copy coordinates from one file and paste them onto the rest of the roll. View a whole selection as colour-coded pins.

05

Tag music the way collectors tag music

Beyond artist and album: BPM, initial key, ISRC, UPC, label, engineer, producer, mixer, ReplayGain values, and lyrics — across more than thirty audio formats.

06

Write carefully, or not at all

Every value is validated before the write. Originals are backed up first. Undo and redo work across the session, and a failed file never takes the batch down with it.

Who it's for

Four kinds of library, one set of problems.

Music & audiophiles

Your player is only as smart as your tags.

Roon, Plex, Navidrome, and Jellyfin all group by AlbumArtist, not by folder. One inconsistent field and a box set explodes into fourteen albums. EveryMark edits the fields those servers actually read, across FLAC, WAV, AIFF, DSD, ALAC, APE, WavPack, MP3, Opus — and the tracker formats nothing else will touch.

Photographers

Fix the card dump, not the catalogue.

Corrections written into a catalogue stay in that catalogue. Corrections written into the file survive the export, the client handoff, and the next piece of software you switch to. Set capture dates, drop GPS onto a roll that had none, and stamp copyright and credit lines across a delivery before it leaves.

Fix it once, in the file, and stop re-fixing it.

Match overrides live in your server's database. Rebuild the library, migrate to Jellyfin, or hand the drive to someone else and they're gone. Write the title, year, season, and episode into the container instead, and every scraper that touches it afterwards gets it right the first time.

Archivists & families

A scan dated today is a photo with no history.

Flatbed scanners stamp every negative with the date you scanned it. Inherited drives arrive with nothing at all. Put the real year back, add the place, name the people in the keywords — and the knowledge stops living only in the head of whoever remembers. It travels with the file.

Coverage

If ExifTool can read it, EveryMark can show it.

The reading and writing engine underneath is ExifTool — the same library archives and forensics labs rely on. EveryMark is the interface it never had.

Local by default

Your files never leave your machine.

EveryMark is a desktop application, not a web service with a desktop shell. Files are read from disk and written back to disk. There is no upload step, no account required to edit, and no telemetry.

  • — No file ever transmitted anywhere
  • — No analytics, no usage tracking, no phone-home
  • — Works with the network off, except map tiles and optional tag lookup
  • — Backups written to a folder you choose

Map tiles and place search send only the coordinates or search term you type — never a file. Tag lookup sends the track or title you ask it to identify, and only when you ask.

Questions

Before you install it.

Does it modify my original files?

Yes — that's the point. Metadata lives inside the file, so writing a tag rewrites the file. EveryMark copies the original into your backup folder before every write, validates each value before it goes in, and leaves the image or audio data itself untouched.

Will editing metadata re-encode my photos or music?

No. Tags are written in place through ExifTool. The pixels and the audio stream are not decoded, re-encoded, or resampled — a lossless FLAC stays bit-identical in its audio, and a RAW file stays a RAW file.

How many files can it handle at once?

Lists of a thousand-plus files scroll smoothly — the grid and list views only render what's on screen. Loading, reading, and saving all run in parallel across files, and a folder is loaded recursively in one action.

What happens if a file fails to save?

That file is reported and the rest of the batch continues. You get a per-file result rather than an all-or-nothing write, and the original is still in your backup folder either way.

Is this just a front end for ExifTool?

ExifTool does the reading and writing, and we'd rather say so than pretend otherwise — it is the most trusted metadata engine there is. EveryMark is everything around it: the file browser, the thumbnails, the field editors and validation, multi-file editing, the map, change review, backups, undo, and export.

When can I actually use it?

The application is built and running on Windows, with macOS and Linux builds configured. We're packaging installers for the beta now. Join the list and you'll get the build and the Pro pricing before anyone else.
