Each guide explains the workflow, best practices, and every tool inside it.
Media
Compress, convert, resize, crop, watermark, and clean photos and vectors. Each media tool takes a file, applies one job, and gives you a download.
Read the guideDocuments
Turn images into documents, convert a PDF into Office files, and measure a draft. These tools cover the file and text jobs that sit next to writing and publishing.
Read the guideDevelopment
Format JSON and SQL, encode Base64, build QR codes, generate an HMAC secret, decode a JWT, capture a public page, and extract tags from one public HTML page.
Read the guideCalculation
Convert timestamps and units, solve percentages and tax, and split a tip. Enter the values you know and read the missing ones.
Read the guideSecurity
Hash a password with bcrypt, checksum text or a file, look up a public IP address, read a domain registration, list published host names, read a certificate, or check the security headers on a public site. Use these only on secrets and hosts you are allowed to review.
Read the guideText & Content
Change letter case, clean a draft, generate placeholder copy, and compare two revisions. These tools are for articles, captions, and form tests.
Read the guideDesign
Pull a subject out of a portrait or sample the colors in a photo. These tools are for visual decisions that are not a file-format conversion.
Read the guideBatch Processing
Run the same image optimization across a set of files instead of opening them one by one.
