A grab-bag of everyday utilities for people who work with files, code and content: developers, designers, writers and anyone who needs to fix a PDF or image quickly. Every tool here runs entirely in your browser, so files never leave your device — which matters when you're handling a signed contract, a client's artwork or an internal data export.
Editing and assembling PDFs
Reach for split, merge, rearrange, rotate or delete-pages when you need to restructure an existing PDF; use the page counter or metadata remover before sending a file out to check its size or strip hidden author/software details.
Resizing, compressing and converting images
Compress when the file is too large to email or upload, resize when you need exact pixel dimensions, and convert when you need a different format (e.g. HEIC or PNG to JPG); the DPI calculator tells you the physical print size at a given resolution.
Encoding, formatting and inspecting data
Use the JSON, CSV, Base64 and URL tools to reshape or clean data payloads, and the JWT decoder, hash generator and timestamp converter to inspect tokens, verify integrity or read machine dates.
Developer helpers and generators
Test a pattern with the regex tester, decode a schedule string with the cron parser, spot changes with the diff checker, or spin up IDs and random values when you need throwaway test data.
Colour, type and layout for design
Convert colour values between HEX, RGB and HSL, check a foreground/background pair meets legibility contrast, build a palette, and work out rem-to-px or line-height when translating a design into CSS.
Counting and tidying text
Count words or characters against a limit, estimate reading time for an article, fix capitalisation with the case converter, or clean a messy list by sorting and removing duplicates.
