how-to.
Short, verified guides for common tasks. Every one uses browser tools — no uploads, no signup, no signup wall halfway through. Each guide has a specific outcome you can copy or run.
Image tasks
Compress JPG under 100 KB (or any target)
Target file-size iteration with MozJPEG.
Remove a watermark from an Instagram screenshot
LaMa inpaint in the browser. When it works, when it doesn't.
Blur faces on a photo before posting publicly
Native FaceDetector + fallback + full sanitizer combo.
Strip GPS and camera metadata from a photo
Why you should, and how in one click.
Dev tasks
Decode a JWT in the browser (and in one shell line)
Browser + curl + jq recipes. When to sign your own.
Format SQL for Postgres, MySQL, or BigQuery
One tool, 15 dialects, keyword-case + indent config.
Convert YAML to JSON (and back, without losing types)
Boolean / int / null gotchas + one-click round-trip.
PDF tasks
Extract every image from a PDF (bulk, browser-only)
Two modes: per-page render vs embedded-object extract.
Permanently redact a PDF (so text can't be recovered)
Rasterized black-box redaction, why it beats "black rectangle over text".
