Utilities that just work
Small, fast and honest tools for your PC: duplicate file finder, disk space analyzer, file recovery. No ads, no accounts, no telemetry — install and use.
Battery Health Check
Free Windows app that shows what your laptop battery is really worth: design capacity vs full charge capacity, wear in percent and charge cycles — read straight from Windows, no vendor tools.
Bulk File Renamer
Free Windows app that renames many files at once: build a rule chain — find & replace, numbering, case, extension — and watch every new name in a live preview before anything touches the disk. One click renames, one click undoes.
Checksum Verifier
Free Windows app that verifies downloaded files against MD5, SHA-1, SHA-256 or SHA-512 checksums — paste the expected hash, get a green or red badge. Streaming reads, no size limit, fully offline.
Color Picker
Free Windows app that reads the exact colour of any pixel on your screen: live preview, one-click pick anywhere, HEX/RGB/HSL values and a history wall that copies as you work.
Dead Pixel Test
Free Windows app that checks a monitor for dead, stuck and hot pixels: fullscreen solid colours, a smooth gradient and a flashing stuck-pixel fix mode. No browser, no ads, works offline.
Disk Space Analyzer
Free Windows app that shows what is taking up space on your drive: an interactive treemap, a breakdown by file categories and the largest files list. Cleanup goes to the Recycle Bin, and the interface speaks 16 languages.
Duplicate File Finder
Free Windows app that finds exact duplicate files, similar photos, and duplicate music by tags or sound — results appear live while scanning, and deleted copies go to the Recycle Bin. Download free, available in English and Russian.
Emoji Picker
Free Windows app that finds the right emoji by keyword and copies it in one click — 546 emojis, a recent strip and zero internet.
Empty Folder Cleaner
Free Windows app that finds every empty folder — including long chains where folders only contain other empty folders — and removes them to the Recycle Bin. Manual selection, one click, nothing is deleted behind your back.
EXIF Remover
Free Windows app that strips EXIF, XMP, IPTC, comments and text chunks from photos — losslessly, without re-compressing a single pixel, and without uploading anything.
File Lock Finder
Free Windows app that answers “who is locking this file?”: Windows itself reports the processes holding it open — names, PIDs, one click, read-only.
Folder Icon Changer
Free Windows app that gives any folder a custom icon — an .ico file or any .exe / .dll whose icon you want to reuse. Works on Windows 10 and 11 in bulk, shows the change instantly, and resets with one click.
HEIC to JPG Converter
Free Windows app that converts iPhone HEIC/HEIF photos to JPG in a batch — set the JPEG quality with a slider, choose where the results go, and convert offline. No uploads, no accounts, no telemetry.
Image Compressor
Free Windows app that makes photos and screenshots smaller — pick a JPEG quality from 10 to 95 or an exact target size in KB/MB, cap the max side, and read “saved N%” on every file. Fully offline, and originals are never overwritten.
Image Resizer
Free Windows app that resizes images in batches — by width, height, a bounding box or a percentage — with high-quality resampling and zero fear of ruining your originals.
Keyboard Tester
Free Windows app that shows which keys work and how many keys your keyboard can hold at once — press, see it turn green, check for rollover.
LAN Device Scanner
Free Windows app that shows every device on your local network: routers, phones, TVs, printers and sleeping gadgets — one ping sweep plus the ARP table, no deep scanning.
Mouse Click Test
Free Windows app that counts left, middle and right clicks, measures clicks per second and tests your double-click speed against a 250–900 ms threshold. Fully offline — no click history is recorded.
PC Specs
Free Windows app that shows what is inside your computer: CPU model, cores and clock, RAM size and modules, graphics adapter, disks, motherboard, BIOS — in plain readable cards.
Port Owner
Free Windows app that answers “what is using this port?”: every TCP/UDP endpoint with the process name and PID behind it, searchable and copyable.
QR Code Generator
Free Windows app that makes QR codes for links, Wi-Fi networks and e-mail — with a live preview and crisp PNG export, fully offline.
QR Code Scanner
Free Windows app that reads QR codes from image files — screenshots, photos, downloads — with a pure offline decoder, no camera and no uploads.
Refresh Rate Test
Free Windows app that reads the current display mode through Win32 and measures what your monitor really delivers — reported Hz, every available mode, real FPS and frame times, plus a moving bar that makes stutter visible.
Screen Ruler
Free Windows app that turns your screen into a ruler: a draggable pixel ruler with live readout, horizontal or vertical, ghost-transparent over anything you measure.
Startup Manager
Free Windows app that shows everything that starts with your PC — Registry Run and RunOnce entries and the Startup folder — and toggles each one on or off with the same StartupApproved mechanism as Task Manager. Nothing is deleted; user entries need no administrator rights.
WebP Converter
Free Windows app that converts images to WebP — losslessly, pixel-perfect — and turns WebP files back into PNG or JPG so any program can open them. Batch, offline, nothing uploaded.
Wi-Fi Password Viewer
Free Windows app that shows the passwords of every Wi-Fi network this PC has ever connected to — masked by default, revealed with one click and copied to the clipboard.
Wi-Fi Signal Monitor
Free Windows app that turns your Wi-Fi signal into a live 2-minute graph — one measurement per second through netsh, no admin rights. Signal in percent, a plain-word quality rating, SSID/BSSID and receive/transmit speeds, so you can find the best spot for the router or your laptop.
