About us
PDF tools that never ask for your files.
Online PDF Editor is a free collection of everyday PDF tools built on one simple idea: editing a document should not require sending it to a stranger's server.
Most online PDF services upload your file, process it remotely, and ask you to trust that it is deleted afterward. We took a different route. Every tool on this site runs locally in your web browser, so contracts, invoices, medical forms, and ID scans never leave your device.
How it works
You choose a file
Pick a PDF or image from your device, or import one from Google Drive or Dropbox. The file is opened directly by your browser.
Your browser does the work
Open-source libraries such as pdf-lib, PDF.js, and Tesseract run locally to render, edit, and rebuild the document.
You download the result
The finished file is created in memory and saved where you choose. Close the tab and the working copy is gone.
Want to verify it yourself? Open your browser's developer tools, switch to the Network tab, and run any tool — you will not see a request carrying your document. Our guide on how browser-based PDF tools work walks through it.
What we believe
Your files stay on your device
Every tool runs inside your browser. PDFs and images are read into memory on your device, processed there, and handed back to you as a download. There is no upload step, no file server, and nothing for us to store, read, or lose.
No account, no paywall, no watermark
You do not need to sign up, sign in, or hand over an email address to use a tool. Results are not stamped with our branding and are not limited to a number of tasks per day.
Honest about limits
Browsers are powerful, but they are not a desktop publishing suite. Where a result can vary — repairing damaged files, OCR on low-quality scans, or very large documents — we say so on the tool page rather than promising perfection.
Fast, focused, and accessible
Each tool loads only the code it needs, heavy work runs in background workers so the page stays responsive, and controls are built to work with a keyboard and screen readers.
What you can do
- Organize — merge, split, reorder, rotate, and delete pages.
- Optimize — compress, repair, resize, flatten, and run OCR to make scans searchable.
- Convert — turn JPG, PNG, WebP, HEIC, and screenshots into PDF, or export pages as images.
- Edit — add text, images, page numbers, and watermarks, crop pages, and fill forms.
- Secure — sign, redact, password-protect, unlock, compare, and clean metadata.

Keeping the lights on
The tools are free to use. Because processing happens on your device, our running costs are limited to hosting a static website, which is what lets us keep it free without selling your data. We use Google Analytics to understand which pages and tools are useful; it measures page visits, never the contents or names of your files. Details are in our privacy policy.
