How this actually works
Each tool runs entirely with JavaScript already loaded in this page — PDF tools via pdf-lib and pdf.js, image tools via the browser's native Canvas API, and everything else with plain JavaScript. Your files or input are read into browser memory, processed, and handed back as a download or copyable result. This page itself is served by a small Laravel route; Laravel never sees your files either. The only backend in use is Supabase, and only for two optional things: signing in with a magic link, and — only if you're signed in — a log of which tool you ran and when. Honest limits worth knowing: Compress PDF flattens each page to a re-encoded image (great for scans, not ideal if you need selectable text after); HEIC conversion uses a small on-demand converter when the browser cannot decode HEIC natively (Safari often works without it); Fill PDF Form is best-effort for simple AcroForm fields, not a full Adobe Forms replacement; and Word/Excel/PowerPoint ⇄ PDF genuinely needs a server-side engine, so it isn't included — this build only ships tools that can honestly run client-side.
Questions people actually ask
What metadata fields can I change?
Title, author, subject, and keywords — the fields most PDF readers show in a document's properties panel.
Can I remove metadata instead of changing it?
Yes — clear a field and save to blank it out entirely.
Does it show me the current metadata before I change it?
Yes — every field is pre-filled with whatever the PDF already has, so you can see the existing values before editing them.
How do I enter multiple keywords?
Comma-separated — each one becomes a separate keyword entry when saved.
Does this change the file's modification date?
Yes — saving updates the PDF's internal modification date to the current date and time automatically, alongside whatever fields you changed.
Does editing metadata affect the actual page content?
No — only the document's info fields (title, author, subject, keywords) change; pages, text, and images are untouched.
What if the PDF has no existing metadata?
The fields just start blank — enter whatever you want and save to add metadata that wasn't there before.
Is the file uploaded anywhere to read its metadata?
No — it's read and edited entirely in your browser using pdf-lib.
Is this really free, and is there a file size limit?
Yes — no account, no paywall. Since processing happens in your browser's memory rather than uploading anywhere, the practical limit is your device's available RAM, not a server quota. Very large files (500+ pages) may run slower, especially for Compress and PDF→JPG.
Does anything about my file get sent anywhere?
No. Every tool runs with pdf-lib/pdf.js loaded in this page; your file is read into browser memory and never leaves it. The only network call this app makes for your account is Supabase auth — and that only stores which tool you ran and when, never file content.
Why isn't Word/Excel/PowerPoint → PDF included?
Converting Office formats accurately needs a real rendering engine (what Word or LibreOffice use internally) — no browser library does this reliably. Rather than ship a broken version, it's left out.
Does TechDriven Tools have OCR (text recognition)?
Yes — OCR PDF recognizes text in scanned or photographed pages using Tesseract.js, running entirely on your device, and gives you a searchable PDF or a plain text file. Nothing is uploaded for this either.
Can I use this without an internet connection?
Once the page and its libraries have loaded once, yes — the tools themselves need no network access. Signing in and viewing history do require a connection, since those talk to Supabase.
What happens to the "history" if I sign in?
Only a row per tool run — the tool's name and a timestamp. No filename, no file content, ever. You can see the full list any time via the History button.
Are the non-PDF utilities (password generator, JSON formatter, etc.) private too?
Yes — same rule as the PDF tools. Word Counter, Case Converter, Password Generator, UUID Generator, Base64, Hash Generator, JSON Formatter and JWT Decoder all run with plain JavaScript already loaded in this page; nothing you type or paste is sent anywhere.

Why use Edit PDF Metadata
- Fix an incorrect author name left over from the software that created the file.
- Add a proper title so the document shows correctly in file browsers and PDF readers.
- Remove identifying information before sharing a document more broadly.
- Standardize metadata across a set of related documents.
How it works
PDF files carry a standard set of document-info fields (Title, Author, Subject, Keywords, and a few others) separate from the visible page content — the same fields a file manager or PDF reader's "Properties" panel shows. This tool reads those fields via pdf-lib, lets you edit them, and writes the updated values back into the file without touching any page content.
What metadata doesn't cover
These fields are separate from visible page text — editing them changes what a PDF reader's properties panel shows, not anything printed or displayed on the pages themselves. If you need to redact or change visible content instead, see Redact PDF.
Why people search for Edit PDF Metadata
View and change the title, author, subject and keywords stored inside a PDF. If you arrived from a comparison article, Edit PDF Metadata is the working utility those guides point at: labeled options, local processing, and a download you can verify.
Edit PDF Metadata sits in our PDF Tools group. The page is built so you can finish the job without creating an account, installing a desktop pack, or sending the payload to an unknown converter API.
Who Edit PDF Metadata is for
- The file or text is sensitive enough that uploading feels wrong.
- A desktop suite is overkill for a one-page or one-photo job.
- You want a second opinion after another converter produced a weird output.
- You need a result now and do not want another account wall.
Recommended workflow
Add unlocked PDFs → set order or ranges → run → open the download and spot-check first, middle, and last pages.
- Open Edit PDF Metadata (also available from category hubs and ⌘K).
- Use the labeled fields or dropzone — options match what Edit PDF Metadata actually does.
- Run the tool and wait for local progress to finish.
- Download or copy the result, then verify on the device where you will share it.
Tips that improve results
- On phones, plug in power for large PDFs, videos, or spreadsheets.
- Prefer UTF-8 text for developer converters; weird encodings cause most “broken” results.
- Start with a non-sensitive sample so you learn the options before the real file.
- Change one setting at a time when you are comparing quality or layout.
- Keep the original until stakeholders accept the download.
- Rename the output with date + purpose before you attach it to email.
Common mistakes with Edit PDF Metadata
- Expecting Edit PDF Metadata to replace a full desktop suite for every edge-case format.
- Skipping a sample check and discovering a bad export after the original was deleted.
- Chaining many lossy image/PDF steps when one careful pass would have been enough.
- Using a public computer without clearing downloads afterward.
Privacy model
Processing for Edit PDF Metadata is designed to stay in the browser. Laravel serves the page; it does not receive your file bytes for conversion. Optional Supabase auth only stores which tool you ran and when — never filenames or contents.

FAQ — Edit PDF Metadata
Is Edit PDF Metadata free to use?
Yes. Edit PDF Metadata on TechDriven Tools is free — no account, no watermark, and no paywall for the core workflow.
Does Edit PDF Metadata upload my file or text?
No for processing. Edit PDF Metadata runs in your browser tab. Optional sign-in never stores file contents — only tool names and timestamps if you enable history.
When should I use Edit PDF Metadata?
Use Edit PDF Metadata for PDF Tools jobs where privacy and speed matter: quick one-offs, sensitive inputs, or checking another app’s result without another upload site.
Will Edit PDF Metadata work on my phone?
Yes in a modern mobile browser. Large inputs can take longer because your device does the work locally.
What are the limits of Edit PDF Metadata?
There is no server quota from us. Limits are your device memory, battery, and formats the browser can decode. Edit PDF Metadata will not pretend to support server-only Office or cloud-AI pipelines.
How is Edit PDF Metadata different from upload-based sites?
Upload converters send your content to someone else’s server. Edit PDF Metadata keeps the transform on-device whenever the format allows, which is the safer default for confidential documents, photos, tokens, and configs.
Bottom line
If you need Edit PDF Metadata done quickly and privately, start at /edit-pdf-metadata, run it once on a sample, then process the real input. That is how TechDriven Tools stays competitive: honest capabilities, labeled UI, and content that matches what the tool actually ships.
