About this app

ToolKK brings more than 1,000 practical tools into one searchable app. Handle PDFs and images, extract text with OCR, create QR codes, calculate, convert units, use phone sensors, and format developer data without installing a separate app for every small job.

SEARCH, FAVORITES, AND RECENT TOOLS

Find tools by keyword, save favorites, and return through recent tools. Multiple layouts and custom ordering help you organize your toolbox.

PDF AND DOCUMENT TOOLS

Merge or split PDFs, delete or extract pages, remove blank pages, resize pages, read files, and manage encryption or permissions. Convert PDFs to common document, image, web, and ebook formats, or turn images and documents into PDFs. File tools run after you choose a file; review the exported result before relying on it.

IMAGE, OCR, AND ID PHOTO TOOLS

Compress, crop, resize, rotate, combine, watermark, and convert common image formats, or turn images into a PDF. Extract text with OCR, remove backgrounds, create passport or ID photos, pick colors, and convert HEX, RGB, HSL, and CMYK values.

CALCULATORS AND CONVERTERS

Use scientific, percentage, age, date, loan, compound-interest, ROI, and CAGR calculators. Convert common units, currencies, number bases, Unix timestamps, pixels, and centimeters. Health calculations are provided for general reference only.

QR CODES, BARCODES, AND TEXT

Create and decode QR codes for websites, text, contacts, and Wi-Fi; add a logo, process codes in batches, and work with common barcodes. Count words and characters, clean or sort text, change letter case, edit Markdown, and compare text.

PHONE TOOLS

Use a flashlight, on-screen ruler, protractor, compass, coordinates, bubble level, decibel meter, magnifier, mirror, or magnetic field detector. Other tools include a teleprompter, Pomodoro timer, scoreboard, stopwatch, countdown, and flip clock.

DEVELOPER AND NETWORK TOOLS

Format, validate, or minify JSON; convert XML and YAML; encode or decode Base64, URLs, and Unicode; test regex; and work with timestamps, UUIDs, Cron, JWT, hashes, encryption, text diffs, and HTML escaping. Network utilities include Ping, DNS, WHOIS, IP conversion, and test-data generators.

PRINTABLE WORKSHEETS AND LEARNING TOOLS

Create tracing sheets, stroke-order and pinyin practice, grids, alphabet and word worksheets, math exercises, Cornell notes, lined paper, and dot-grid paper.

AI WRITING, AUDIO, AND VIDEO

Rewrite, summarize, or translate text and generate reports or SEO metadata. Audio and video tools cover trimming, merging, reversing, rotating, speed changes, GIF creation, audio editing, text to speech, and M3U8 playback. Availability is shown on each tool page.

PRIVACY, PERMISSIONS, AND SYNC

ToolKK is available on the web, in the app, and through a mini program. Sign in for account-based favorites, benefits, or supported sync; basic tools that do not require an account remain available without signing in.

Most tools process data on your device or within the page. Some rely on a server or external API and may transmit data to provide the feature. Details appear on the relevant page or in the privacy policy. Permissions are requested when you start a related feature.

FREE TO START, OPTIONAL MEMBERSHIP

ToolKK includes many free tools and optional Premium and Pro memberships. Benefits, limits, billing, renewal, and purchase restoration are shown before purchase.
