Run PDF tools without opening a site
Compress, split, rotate, extract or delete pages, add a watermark or page numbers, protect, unlock, flatten or OCR a PDF, each from the PDF Tools tab in the panel.
File converter extension for Chrome, Edge and Firefox
INDOX opens in your browser's side panel. Drop a file, paste a link or capture the page you are on, then pick a format. You never leave the tab you are working in.
- Free to install
- Checked before anything uploads
- Free-tier files deleted within 24 hours
Rather not install anything? Convert on the web
What can the INDOX extension do?
Find any past conversion
History lists every job with its status. Search it, show only finished or failed jobs, and download a result again without converting the file twice.
Set it up your way
In the extension's settings, pick the theme, language and popup size, decide where the INDOX tab sits or hide it, and set your default formats and keyboard shortcuts.
Your files are on indox.org too
Everything you convert in the panel also lands in My Files on indox.org, where you can download it, convert it again or delete files in bulk.
How do I convert a file with the extension?
- 1
Add it to your browser
Pick Chrome, Edge or Firefox at the top of this page and install INDOX from that browser's store.
- 2
Open the side panel
Click the INDOX icon in the toolbar, or the INDOX tab docked to the edge of any page.
- 3
Drop a file and pick a format
Choose PDF, DOCX, TXT or any other format the file supports, press Convert, and download the result when it is ready.
Why use the extension instead of the website?
The website converts files you already have. The extension also works on whatever is in front of you, without opening another tab.
- Capture the visible area, a region or the full page as an image
- Pull the text out of a screenshot or an image with OCR
- Select text on a page and save it as a PDF, or as Markdown that never leaves your browser
- Right-click an image, video or audio file to convert it
- Compress, split, rotate, watermark or protect a PDF from the PDF Tools tab
- Type indox convert and a link in the address bar
What happens to your files?
Before upload
The extension checks the file's size against your plan, its real type, your credits and your connection before anything is sent. If a check fails, nothing is uploaded.
Size
Your plan sets the largest file you can send, and the panel tells you before you upload if a file is over it.
Deletion
Free-tier files are deleted within 24 hours after the job finishes. Paid plans keep results for 180 days so you can download them again.
Account
The extension uses your indox.org account, so credits, history and files are the same on the website and in the panel.
Why the extension asks for each permission
- Read and change data on all websites: so the INDOX tab can sit on the edge of every page. It reads nothing until you pick an action, and you can hide it on one site or everywhere.
- Active tab and scripting: to capture or read the page you are on, and only when you ask.
- Side panel, context menus, downloads and notifications: to show the panel, add the right-click actions, save results and tell you when a job is done.
- Cookies: to pick up your indox.org sign-in, so you do not log in twice.
- Storage and alarms: to keep your settings and check on running jobs.
- Clipboard (optional): asked for the first time you convert something from the clipboard.

INDOX extension FAQs
Which browsers does the INDOX extension work in?
Chrome, Microsoft Edge and Firefox. Each one installs from its own store, using the buttons at the top of this page.
Is the extension free?
Installing it is free, and it runs on the same account and credits as indox.org, free tier included. Paid plans add credits, larger files and longer storage.
Can I use my indox.org account?
Yes. Sign in from the side panel with email, Google or Apple. If you are already signed in on indox.org, the extension picks that up.
How do I open the side panel?
Click the INDOX icon in the toolbar, or the INDOX tab on the edge of the page. To move the panel to the left, use your browser's own side panel setting. Extensions cannot move it.
Why does it ask to read data on all websites?
So the INDOX tab can sit on the edge of every page. It reads nothing until you choose an action, and you can hide it on a single site or turn it off in the extension's settings.
Can I limit which sites it can see?
Yes. In Chrome or Edge, open the extension's details and set site access to on click or to specific sites. The INDOX tab then appears only where you allow it, and the toolbar icon still opens the panel.
Are my files uploaded?
Only when you press Convert. Size, type and credit checks run in your browser first. Saving selected text as Markdown happens entirely in your browser and uploads nothing.
How long are converted files kept?
Free-tier files are deleted within 24 hours after the job finishes. Paid plans keep them for 180 days.
Does it work offline?
No. Conversions run on indox servers, so you need a connection. The panel checks for one before it uploads and tells you if you are offline.
Which file types can it convert?
Documents, images, video and audio. The panel reads its format list from the same converters as indox.org, so a format added there shows up in the extension too.
Can I turn a whole web page into a PDF?
Yes. Choose Page in the panel to send the page as you see it, or capture it as an image. A PDF open in the tab can be converted directly too.
Does it work in incognito or private windows?
Only if you allow it. In Chrome and Edge, open the extension's details and turn on Allow in Incognito. In Firefox, turn on Run in Private Windows.
