PDF Metadata Editor

PDF Metadata Editor performs pdf metadata editor as a focused single-page utility. Edit PDF metadata fields including title, author, subject, keywords, creator, and producer. Defaults are tuned for the common case so the first run is one click, with every option that matters exposed for the moments you need to fine-tune the result.

The processing pipeline is straightforward: your input is parsed by the open-source pdf-lib JavaScript library, transformed according to the options you select, and serialised back into a downloadable result. Accepted input formats are PDF. The 200 MB per-file ceiling matches what a typical browser tab can handle without paging to disk.

PDF Metadata Editor is shaped around the recurring needs of two audiences: legal teams preparing exhibit bundles, who use it as a quick utility between bigger tools, and freelancers sharing scanned receipts, who use it as their primary way of getting the job done. Both groups get the same defaults and the same speed.

The browser sandbox isolates the page's JavaScript from the rest of the system, the same way it isolates every other tab you have open. PDF Metadata Editor works inside that sandbox: it reads the file you give it, processes it with the open-source pdf-lib JavaScript library, and writes the result back. Nothing leaves the page's memory unless you choose to download or copy it.

The right moment to reach for PDF Metadata Editor is when you have a focused PDF document workflow job that fits inside a browser tab. Open the page, drop in the file or paste your input, choose the options that matter, and the tool returns the result.

Output handling is intentionally boring: PDF Metadata Editor produces `{name}-metadata-edited.pdf` and triggers your browser's standard "save" behaviour. If you have a default download folder configured, that is where it will land. There is no Favtoo-side history of jobs you have run.

On limits: 200 MB per file is the ceiling. Output formats and quality settings are listed in the controls panel above, and they apply to every run.

PDF Metadata Editor is intentionally narrow in what it does, which makes it easy to slot into a longer workflow. Take its output, hand it to whichever next tool fits the job, and PDF Metadata Editor stays out of your way until the next time you need it.

PDF Metadata Editor is honest about scope: it handles a single, well-defined PDF document workflow step. Specialist edge-case work — uncommon formats, very large inputs, or pipelines that need scripting — is what dedicated desktop apps are for. This page handles the common case quickly.

PDF Metadata Editor is one example of a broader pattern: utility software increasingly works as single-page, client-side experiences. Every page in the catalog is shaped that way, which keeps each tool fast to load and easy to recommend in a single link.

PDF Metadata Editor runs as a regular web page, so there is no install step or permission grant before the first run. The page can be audited by viewing the source or by watching the developer-tools Network tab while a job runs.

A few practical tips that experienced users of PDF Metadata Editor pick up over time. First, keep your default browser updated — the engine relies on standard web APIs and newer browser versions are noticeably faster than ones from a few years ago. Second, close other heavy tabs before processing a large input; the engine shares CPU and memory with whatever else is open. Third, if you re-run the same kind of job often, your last-used settings are remembered for the rest of the tab session, so subsequent runs are essentially one click.

When something goes wrong, the cause is usually one of three things: a malformed input, a browser that is out of memory, or a corporate proxy that is interfering with the page's static assets. The first two are easy to diagnose; the third typically requires asking your IT team to allow the open-source pdf-lib JavaScript library to load.

That is essentially everything PDF Metadata Editor does and how it does it. Open the tool above, drop in your input, and the work happens in the page. If you find yourself reaching for it often, bookmark the page — it loads quickly on subsequent visits, and your most-recent settings are remembered for the rest of the session.
