HyperVideo
Finds every video on a page, shows its size and duration, and downloads it in the quality you pick. It also records your screen with sound.
All extensions
HyperScreen
Captures a screenshot of an entire page and helps you crop it. Handy for a long chat with an AI assistant, a big Wikipedia article or a social media page.
HyperCompress
Compresses files without visible quality loss and keeps everything private. It also converts files between formats: audio and video, documents and images.
HyperPDF
Merges several files into one, deletes and reorders pages, builds a PDF from photos, and reads reviewer comments on the document.
HyperPhoto
Works through large photo collections on your own computer, with nothing uploaded to outside services. Large previews, easy culling and batch renaming.
HyperContacts
Opens your Excel file of partner and client contacts as a proper system with profiles and categories. Everything runs locally, with no risk of a leak.
HyperAlerts
Sets up useful reminders: take a pill, get up for a short walk, rest your eyes. At the chosen time a break timer appears on screen, along with a magnificent ginger cat taking it easy.
HyperCall
For anyone who gets interrupted all day. It opens a window that imitates a video call with colleagues or partners — start it, put your headphones on, and people will leave you alone while you are in a virtual meeting.
Your files stay safe
Files never leave your computer
No document, screenshot or photo is uploaded to an outside site or cloud. Everything happens inside your browser, and the results are saved only on your computer.
No accounts, no subscriptions
Nothing to register and nothing to pay for. The extension works the moment it is installed.
You leave no digital trail
The extensions collect no statistics, show no ads and call no third-party services.
Works without an internet connection
Compression, PDF editing and Excel work need no network — which matters on the move and inside closed networks.
How to install
Find the extension you need and press Install
The right Chrome Web Store page opens in your browser.
Press Install on the Chrome Web Store page
A blue Install button appears on the right of the listing — click it. If the page opened in a different browser (Safari, say), copy its address into Chrome, Yandex Browser, Edge or Opera and press the button there.
Pin the icon to the toolbar
Open the extensions list in your browser settings and pin the new extension to the toolbar.
Done — open the extension
Click its icon in the browser. No account, no payment, no setup needed.
All four browsers (Chrome, Yandex Browser, Microsoft Edge, Opera) are built on the Chromium platform, so extensions for them all come from one place — the Chrome Web Store. Chrome and Yandex Browser open the listing directly. Edge asks once for permission to install from other stores — choose “Allow”. Opera needs the free Install Chrome Extensions add-on, after which the install button appears on the normal listing page.
About the project
These browser extensions are free and replace commercial software. They need no account, no subscription and no uploading of your material to outside sites or cloud servers. The browser's own capabilities let them work with files without those files ever leaving your computer. Their quality and safety are backed by Google's review: every one of them is published in the official Chrome Web Store.
Frequently asked questions
What is Smart Browser?
A set of free extensions for Chromium-based browsers — Chrome, Yandex Browser, Edge and Opera. They cover the everyday jobs people normally use online services for: downloading video, full-page screenshots, editing and compressing PDFs, working with Excel spreadsheets, generating QR codes, culling photos and setting reminders. The difference is that all processing happens locally, inside the browser.
Are the extensions free?
Yes, every one of them is completely free: no subscriptions, no in-app purchases, no limits and no watermarks.
Do they work in Yandex Browser, Edge and Opera?
Yes. They are Chromium-based and install from the same Chrome Web Store. Yandex Browser installs directly, Edge asks once to allow extensions from other stores, and Opera needs the free Install Chrome Extensions add-on.
Where do my files and data go?
Nowhere. Documents, images and spreadsheets are processed in browser memory and stay on your computer: no servers, no accounts, no analytics. The one exception is HyperShort, which sends the page address to your own short-link server — the one you configure yourself, not a third-party service.
Do I have to install all of them?
No. Each works on its own — install only the one that solves your problem.
Is an internet connection required?
For downloading video, naturally. Everything else — compression, PDF, Excel, photos, QR codes, reminders — works offline.
Who makes these extensions?
They are built by a single developer, Dmitri Ignatiev, and published in the official Chrome Web Store, where they pass its review.
How do I uninstall one?
Right-click its icon next to the address bar and choose “Remove from Chrome”. No leftover files and no accounts to close.
