Frequently asked questions

A browser-based editor for the titles and keywords of your stock files: photos, vectors, and videos. It works on a whole folder or a selection, with bulk editing, AI generation, renaming, and CSV export. Nothing to install, and your files are never uploaded to a server.

Editing, renaming, and CSV export are free and don't need an account. A subscription is only needed for AI generation — see the AI generation section below.

Any modern one. There are two ways to open files. Files mode works everywhere: Chrome, Edge, Firefox, Safari, and every browser on iPhone and iPad. Folder mode needs the File System Access API, which Chrome and other Chromium-based browsers have on a computer. Firefox and Safari don't, so there you'll use Files mode.

Folder mode edits files in place: metadata and new file names are written straight into your originals on disk. Files mode works on the files you pick or drag in. The edits stay in the browser tab, your originals aren't touched, and when you're done you download the edited copies (one by one through the share sheet, or all at once as a ZIP). In a browser that can't open folders, the app switches to Files mode on its own. You can also switch between the two on the start screen.

Yes, in Files mode. Safari and every other iOS browser run on the same engine, which doesn't have the File System Access API, so Folder mode isn't available there. You pick files from your device and download the edited copies afterwards. The layout adapts to tablets and phones, with bigger touch targets.

Yes. Browsers built on Chromium support it. In some of them, though, the File System Access API is off by default. If so, turn it on in the browser's settings first, or the app won't be able to open your folder. Files mode works regardless.

It depends on the browser. Here's Brave: 1) Open a new tab and paste brave://flags/#file-system-access-api into the address bar (Brave won't open it from a link). 2) Set File System Access API to Enabled. 3) Click Relaunch at the bottom of the page. After the restart, reload Canella Meta Editor.

No. In Folder mode, the browser reads and writes them directly on your device through the File System Access API. In Files mode, they stay in the browser tab. Either way, our servers never get a copy. If you use AI generation, your browser sends the file being processed straight to the AI provider you chose — not to us.

JPG, PNG, EPS, SVG, MP4, and MOV. Files in other formats (HEIC, WebP, DNG, and so on) are skipped, and the app tells you which ones it left out.

In Folder mode, yes: changes are written into the originals. So keep a backup of anything you can't afford to lose, as with any tool that edits files. In Files mode, no: the originals aren't touched and you download edited copies. Those edits only live in the open tab, so download them before you close it.

Not by default: only the files directly inside the folder you picked. To include subfolders too, turn on Scan subfolders in Settings → General.

Up to around 500 works best. If you open a larger folder, the app asks you to confirm first, because a very large batch can slow things down.

No. Once the page has loaded, you can edit without a connection. Internet is only needed for things that talk to an outside service, like AI generation.

The title and the keywords, which is what stock platforms look at. How they're stored inside the file is in the Technical details section.

Yes. Remove or replace a keyword, replace or remove text in titles, or clear metadata for every file in the current view. Or select some files and apply the action only to those. AI generation, CSV export, and renaming can be limited to a selection too.

Yes. Filter by status (no metadata, has metadata, failed), by format, or by file name, and switch between grid and list views.

Yes. Set a prefix, and every file gets that name plus a sequential number, in one go.

Yes. One spreadsheet for all files, only the ones with or without metadata, or just your selection. It's ready for Adobe Stock and other stock platforms.

The app sends a file to the AI provider you set up and gets back a title and a set of keywords. You can give it a topic and a list of keywords that must be included, run it for one file or a whole batch, and keep working while the queue runs. Then you review the results and fix whatever needs fixing.

An account, an active subscription, and your own API key from the AI provider. Everything else in the editor works without them, as a guest.

In your browser, encrypted. We don't store it. When you run a generation, the encrypted key is sent to our server only to be decrypted for that one request.

Two separate things. The AI provider bills you directly, at its own rates, for the generations you run. And using AI generation inside Canella Meta Editor needs an active subscription.

Yes, for images and videos alike. You can also edit any file's metadata by hand.

Not for editing. Everything except AI generation works as a guest. An account, together with a subscription, is what unlocks AI generation.

Write to us through the Contact page. Your account data is removed from our main systems right away.

Title and Keywords, stored as the XMP fields dc:title and dc:subject, which is what stock platforms read. Nothing else is touched, including whatever the camera wrote into EXIF.

Straight into the file, as a standard XMP block, for every supported format. Images and video aren't re-encoded or recompressed.

Through the browser's File System Access API. The browser asks for permission once, for the folder you picked, and the app can only reach files inside it.

Your preferences (theme, language, AI settings) and your encrypted API key, in the browser's local storage. Clearing the browser's data removes all of it.

Generations run one at a time, with short pauses to stay within the provider's limits. The file is sent to the AI provider from your browser. Our server only prepares the instructions for the AI and decrypts your key for that request.

Yes, using your browser's built-in feature, with no separate download. It gets its own icon and window, without the address bar and tabs. Steps for different devices and browsers are below.

Chrome 1) Open the app. 2) Click the Install icon at the right end of the address bar. If you don't see it, open the ⋮ menu and choose Install page as app. 3) Confirm with Install. Safari on a Mac (macOS Sonoma 14 or later) 1) Open the app. 2) Choose File → Add to Dock, or click the Share button and then Add to Dock. 3) Click Add.

1) Open the app in Safari. 2) Tap the Share button (a square with an arrow). 3) Scroll down and tap Add to Home Screen. If you don't see it, tap View More first. 4) Tap Add.

Chrome 1) Open the app. 2) Tap the ⋮ menu and choose Install app (on some versions, Add to Home screen). 3) Confirm with Install. Samsung Internet 1) Open the app. 2) Tap the menu and choose Add page to, then Home screen. Firefox 1) Open the app. 2) Tap the ⋮ menu, then Install.

Yes, once you've opened it online at least once. After that it opens without an internet connection.
