Honest by design
- Free tools never ask for money, an account or an email address.
- No popups, tours, upgrade banners or requests to rate it.
- Pro tools are tagged before you open them. You’re never asked to pay after you’ve done the work.
- Pro is one payment. Once unlocked it stays unlocked, even offline.
- Opening every PDF in Plainware PDF automatically is optional, and off until you turn it on.
Permissions, and why it asks
storage- Keeps your settings, any signatures you choose to save and your Pro licence in this browser.
activeTab- Lets it read the PDF in the current tab, and only after you click the Plainware PDF button.
contextMenus- Adds “Open in Plainware PDF” when you right-click a link to a PDF.
declarativeNetRequestWithHostAccess- Used only if you turn on “Open PDFs in Plainware PDF automatically”. Chrome asks for site access at that moment, not at install.

Questions
Are my files uploaded anywhere?
No. Plainware PDF opens and changes PDFs inside your browser, on your computer. It makes only two kinds of network request: checking a Pro licence key with Dodo Payments, and fetching a PDF you asked it to open from a web address.
Does it work offline?
Yes. Once it’s installed, every tool works without an internet connection. Pro needs a connection once, to check your key when you enter it. After that it stays unlocked offline.
What’s free, and will that change?
Nine tools are free: merge, compress, fill and sign, split, images to PDF, PDF to images, rotate and delete pages, unlock, and the viewer. They have no daily limits, no waiting and no watermark, and they never ask for money, an account or an email address.
Is Pro a subscription?
No. Plainware Pro is one payment: ₹249 in India or $9 elsewhere. The same key also unlocks Pro in other Plainware extensions.
Can it edit the existing text in my PDF?
Not in its original font. Cover and retype (Pro) puts a box over the old text and lets you type new text on top. The old text is hidden on the page but is still inside the file, so don’t use it to remove private information.
Why won’t my form fill in?
Some government and tax forms use XFA, an older Adobe form format. Plainware PDF spots these and tells you it can’t fill them. They usually need Adobe Acrobat Reader.
Is a drawn signature a digital signature?
No. A drawn, typed or uploaded signature is placed on the page as an image, like signing a printout. Plainware PDF doesn’t create certificate-based digital signatures, such as a DSC or eSign.
Is it approved by any exam board or government portal?
No. Plainware PDF isn’t connected to or approved by any exam board, university, employer or government portal. Presets such as 100 KB are just sizes. Always check the portal’s own rules.
Which browsers does it work in?
It’s made for Google Chrome on Windows, Mac, Linux and ChromeOS. Microsoft Edge can also install extensions from the Chrome Web Store.
What does it keep on my computer?
Your settings, signatures you choose to remember, form drafts until you download or discard them, and your Pro licence. They stay in this browser. You can delete signatures and drafts in the extension, and removing the extension removes everything.
