Every feature, explained

Unloads inactive tabs on a timer you set, freeing the RAM they were holding. Pinned, audio and whitelisted tabs are always protected. PRO (one-time) adds a custom timer in seconds.

Blocks ads, trackers, analytics, and malware/phishing at three coverage levels. All rules ship with the extension — no external list fetching, ever.

Blocks third-party scripts loaded from external domains at three coverage levels; the All level is PRO.

Blocks web font downloads and substitutes system fonts, reducing page weight and improving load speed. Three levels let you choose how aggressively fonts are replaced.

Defers loading of below-the-fold images, iframes, and off-screen resources so the content you can see loads first. Three levels of coverage available.

Starts loading likely next pages in the background before you click, so navigation feels instant. Two levels: same-site only or all domains, both free.

Stops videos from autoplaying across the web. Allow Common keeps major video and meeting sites playing; Block All stops everything except whitelisted sites.

Detects when a page has been broken by SuperchargePerformance's features and automatically disables them on that page. A safety net for aggressive settings.

Strips the ad fields from YouTube player responses before playback, and substitutes Twitch ad segments with clean backup streams. On by default.

Auto-Reject Cookie Banners runs on by default — no setup needed. Smart Page Cleanup is a separate opt-in toggle that adds CSS-based ad-slot hiding and popup blocking.

Exempt any domain from specific SuperchargePerformance features. Block ads on everything except your banking site. Keep Spotify active while still blocking its ads.

PRO-only toggle that blocks all image requests. Lighter page loads for text-heavy research, documentation reading, or data-constrained connections.

PRO-only toggle that reduces how often background tab scripts can run, freeing CPU for the active tab. Useful on machines where Chrome consumes high CPU at rest.

PRO-only feature that scans links on the current page and injects preconnect and dns-prefetch hints, resolving domain lookups (and optionally full connections) in the background before you navigate.

SuperchargePerformance's global switch pauses the extension for one hour, then restores your saved settings automatically. Core is free; PRO is a one-time payment.

A vertical tab list in the side panel or a slim in-page rail, with named workspaces, session snapshots, and the Alt+K command bar. All free, with zero telemetry.

Save any set of tabs as a named workspace and switch back in one click. Tab groups, pinned tabs, mute states, and group colors are all preserved. No cloud account required.

Auto-snapshots your tabs every 5 minutes, on by default. Rewind to any of the 50 most recent states after a crash or an accidental closure.

Alt+K opens a full-page Spotlight-style search across open tabs, bookmarks, and browsing history. No match? It falls through to a web search automatically.

Alt+G groups open tabs by domain in one keystroke, skipping pinned tabs. New groups stay expanded unless auto-collapse is enabled. Alt+Shift+G undoes grouping, leaving locked tabs grouped.

Alt+Click a link to preview its content in an overlay without opening a new tab. Read what you need, then dismiss or promote it to a real tab.

Alt+B, Alt+K, Alt+G, hint mode, Alt+wheel tab cycling, arrow scroll — the complete keyboard layer for Chrome tab management. Every action configurable, every shortcut individually toggleable.

Drag a link up to open it in a background tab, or down for the foreground. Selected text works the same: up searches in background, down in foreground. Auto-off on detected web apps like Google Docs.

Hold Shift and letter badges overlay the page's clickable elements. Type the label to activate it. Trigger key and hold/tap mode are configurable in Settings.

Replace Chrome's default new tab with a workspace dashboard. See your workspaces, pinned tabs, and top sites at a glance — with a live clock and unified search bar.

SuperchargeNavigation detects when you open a page that's already in your browser and prompts you to switch to the existing tab rather than creating a duplicate. Enabled by default.

A per-hostname switch that pauses SuperchargeNavigation's keyboard handling on the sites you choose, for web apps that fight over your shortcuts. It disables no other extension.

Hold Alt and scroll the mouse wheel to cycle through your open tabs instead of scrolling the page. On by default, a mouse gesture rather than a registered shortcut, and free.

Raises Chrome's 100% volume cap to 600%. Useful for quiet recordings, online meetings, and podcasts with inconsistent levels.

10-band equalizer covering 32 Hz to 16 kHz, ±12 dB per band. Includes 11 named presets and lets you save a custom curve per site.

Add low-end weight with the one-tap Bass Boost preset or the equalizer's low bands. Saved per site, adjustable while audio plays.

Four stereo-field controls: Fix one ear, stereo width (mono to ultra-wide), 8D Audio, and Headphones crossfeed.

Active tab keeps audio; other audible background tabs mute automatically. Switch tabs and audio follows. Silent mode mutes every tab, including the active one.

Your volume, EQ, and stereo width are saved per website and re-applied automatically next time you visit. Each site keeps its own audio profile. Stored locally.

See every tab currently playing audio in one list. Jump to any of them or mute them directly from the SuperchargeAudio popup — no hunting through your tab bar.

Mono folds both channels into one so one-ear audio plays from both ears. The width slider runs from 0% (mono mix) to 200% (ultra-wide). Width is remembered per site; mono is per-tab and never saved.

Captures a whole scrolling page as one tall image by scrolling and stitching every viewport. Four capture modes, PNG/JPG/WebP or PDF output, all in the free SuperchargeCapture extension.

Records a tab, window, or full screen. Recording a tab skips the OS screen-picker. Mic, system audio, and a live level meter built in. Footage is chunked locally so a crash can be recovered. Free.

A built-in editor for every capture, or any image you paste in: arrow, box, ellipse, highlight, step numbers, spotlight, text, redaction, crop. Copy, save as PNG/JPG/WebP, or PDF. Nothing paywalled.

The video auto-zooms toward each click — and every zoom is an editable timeline segment: retime it, change its strength, drag its aim, or draw one as a box. Rendered locally, for tab recordings.

Records your camera alongside a tab recording. Background blur runs on-device.

One click transcribes your recording's speech into editable caption cues, using a Whisper model that ships inside the extension. Fully offline — the audio never leaves your machine, and it's free.

Drag a blur box over anything sensitive in a recording and add keyframes so it follows what moves. The blur paints over an opaque base, so the original pixels can't bleed through at the edges.

One click scans the audio for dead air and cuts the silent stretches over 0.6 seconds, measured in 50-millisecond loudness windows. Shorter pauses are left alone. The whole pass is one undo step.

Select any clip and set its speed: 0.5×, 1×, 1.5×, or 2×. Where two speeds meet, playback eases through a smooth ramp instead of snapping. Applied at export, and undoable. Free, in the editor.

Drag the trim handles, split at the playhead, and ripple-delete what you don't want. The export plays straight across the cut. Full undo/redo, and edits autosave so you can reopen and keep going.

Upload your own track and the editor mixes it under the recording at export. Automatic ducking dips the music while you speak and brings it back up in the pauses. No fader-riding, no video editor.

Draws pressed keys as pill chips near the bottom of the video so viewers can follow shortcuts. Recognized password, card, and code fields drop their keystrokes before capture.

Exports any recording as a GIF next to WebM and MP4 — up to 120 seconds, three size presets, 12/24/30 fps. Every edit, from zoom to captions, bakes into the loop. Encoded on your machine.

Turn the images of a capture into one shareable PDF, one image per page. The source images stay in local browser storage, with PNG, JPG and WebP available as image formats alongside PDF.

Three of SuperchargeCapture's screenshot modes: Visible captures what is on screen, Region drags a rectangle around any area, Element captures one clicked element. Free, no paid tier.

Screen recordings export as WebM, and as MP4 on browsers that can encode it, with 480p, 720p or 1080p resolution, 24/30/60 fps, and three bitrate tiers. GIF is a separate option.

Finished SuperchargeCapture exports can be shared to Google Drive: the file lands in a 'SuperchargeCapture' folder in your own Drive, viewable by anyone with the link. Optional, on demand, free.

The SuperchargeCapture video editor ships three named presets: Clean, Cinematic, and Tutorial. Pick one, edit, and export as WebM, MP4, or GIF. Free, no paid tier.

Interrupted SuperchargeCapture recordings are not lost: the popup offers a recovery action that opens the saved footage in the editor. Footage stays in local browser storage.

View the CSS of any element and copy its font, colors, spacing and box model with SuperchargeInspect. Everything runs locally with no account.

Copy UI context in one step. A note, an annotated screenshot, and observed styles land in your AI coding tool. Nothing leaves your device until you paste it yourself.

See the declared font-family stack, size, weight and line height on any page, then copy the values with SuperchargeInspect. Everything runs locally.

See the text, background and border colors of any element with SuperchargeInspect. Click a color to copy its hex code. Everything runs locally on your device.

Read the box model of any element with SuperchargeInspect: padding, margin, gap, border radius, display and content size. Runs locally with no account.

Screenshot one element and write your note for an AI coding tool. Copy the annotated screenshot with its reference text, or the clean PNG crop.
