All File & Data Tools
ZIP File Maker & ExtractorCreate a ZIP archive from multiple files or open a ZIP and export its extracted contents from the browser.Bulk File RenamerRename many files by rule using prefix, base name, suffix, starting number, number padding and extension preservation, preview names and download a ZIP.Duplicate File FinderHash file contents with SHA-256 and group files that are byte-for-byte identical even when their filenames differ.QR Code GeneratorGenerate a QR code from text or a URL with configurable size, error-correction level and foreground/background colors, then save PNG.Text Cleaner & Character CounterCount characters, lines and bytes, trim line edges, collapse repeated spaces, remove blank or duplicate lines, sort lines and copy the cleaned text.Secure Password GeneratorGenerate passwords in the browser using cryptographically secure randomness with controls for length, uppercase, lowercase, digits, symbols and ambiguous-character exclusion.File Size & Type AnalyzerInspect multiple files for filename extension, MIME type, individual size and total selected size.File Hash CalculatorCalculate SHA-256 or SHA-1 digests for a local file in the browser and copy the resulting hash.Barcode GeneratorGenerate standard barcodes such as CODE128, EAN-13, UPC, CODE39, ITF14 and MSI, set height and human-readable text, then save SVG.Image Base64 ConverterConvert an image file to Base64/Data URL text or decode Base64/Data URL text back into an image.JSON Formatter & ValidatorPretty-print JSON, minify it to one line, detect syntax errors and copy the result.CSV to JSON / JSON to CSV ConverterConvert tabular CSV text to JSON or convert JSON records into CSV, then copy the result.Text Compare / DiffCompare two text blocks line by line and highlight added, deleted and changed content.Unix Timestamp ConverterConvert Unix timestamps in seconds or milliseconds to readable date/time and ISO values, convert date/time back to Unix, and insert the current time.PX to CM / Inch / DPI CalculatorConvert between pixels, inches, centimeters and millimeters using a chosen DPI value.
Guides and explanations
SHA-256 File Hash and Checksum VerificationUse SHA-256 to compare file bytes with a published checksum and understand what a matching hash does—and does not—prove.Unix Timestamp: Seconds vs MillisecondsAvoid the most common epoch-conversion error by distinguishing second-based Unix time from millisecond timestamps.
How this collection is organized
Each tool has its own crawlable URL, unique title, description, documentation, structured data and contextual links. This helps users and search engines distinguish tasks that may sound related but operate differently—for example cropping versus resizing, PDF merging versus page extraction, or video conversion versus compression.
