Premium PDF Editor — FreeMediaTools

View, annotate, add text and draw on PDF pages. Edit and download edited PDF — all in your browser.

Offline & private — edits on your device only.
This editor rasterizes pages for annotation export — text becomes part of the page image in the downloaded PDF.

Online PDF Editor — Edit PDF Files in Your Browser

The Premium PDF Editor from FreeMediaTools is a powerful, privacy-first web application that allows you to edit PDF files directly in your browser. This online PDF editor is designed for speed, security, and ease-of-use: no uploads, no accounts, and no hidden fees. Everything runs locally on your device so your documents remain private.

What you can do with this Editor

Use the editor to annotate PDFs, add text to PDF pages, draw freehand, insert notes and comments, and export your edits as a new downloadable PDF. Common uses include marking up contracts, signing documents, filling forms visually, stamping pages, and creating annotated copies for sharing.

Key Features

How the Online PDF Editor is Built

This browser PDF editor uses modern web technologies to deliver a feature-rich editing experience without sending your files to servers:

Technical Details & Workflow

The edit-and-export flow works as follows:

  1. When you load a PDF, PDF.js parses it and renders each page to the base canvas at an appropriate resolution that fits the viewer.
  2. An overlay canvas captures user annotations (drawings, text). Every time you finish an annotation, the overlay is saved in-memory as an image (data URL) associated with the current page.
  3. On export, a new PDF document is created with pdf-lib. For each page we re-render the page at a good resolution, draw the saved overlay image onto the page canvas, convert that composed canvas to PNG bytes, then embed that PNG into a new PDF page.
  4. The final PDF is saved in the browser and offered for download as edited.pdf. Because the exported pages are images, the edits are visually exact and portable across PDF viewers.

Why this client-side approach matters

There are trade-offs between client-side and server-side PDF editing. Our approach focuses on privacy, speed, and simplicity:

Limitations & Advanced Use Cases

While this editor is powerful for many use-cases, there are some limitations to be aware of:

Security & Privacy

Security is central to this tool. Because all processing is done client-side, your PDF never travels over the internet. If you want to remove all in-memory traces, simply close the browser tab — no traces remain on servers. We do not collect or store any files.

Frequently Asked Questions (FAQ)

Q: Is this PDF editor free?
A: Yes — this PDF editor is free to use. It is built and provided by FreeMediaTools as a privacy-friendly utility.

Q: Will my document be uploaded anywhere?
A: No — all processing occurs in your browser. Nothing is uploaded to servers.

Q: Can I edit text inside the PDF (native editable text)?
A: This editor places visual text and annotations on top of the page and exports them flattened into the page image. Editing native PDF text objects requires more advanced PDF manipulation tools and is outside the scope of a pure client-side editor.
