Toolbelt

Quick client-side dev utilities: image resizer, terminal/markdown formatter, CSV viewer. No uploads, no servers, no telemetry.

Toolbelt is a set of fast, private developer / solopreneur / business utilities that run entirely in your browser. Nothing you open is uploaded aywhere — there are no servers, no accounts, and no tracking. All done client side browser. ■ IMAGE TOOLS • Resize — width/height with aspect lock, presets, batch, PNG/JPEG/WebP/AVIF with quality control, download as a ZIP. • Convert — batch format conversion between PNG, JPEG, WebP and AVIF, plus a dedicated SVG → raster section. • Crop — drag a selection with optional aspect-ratio lock; exports at full resolution. • Icon / Size-Set generator — one source image into a folder-structured ZIP: favicon + web-app icons (incl. multi-size favicon.ico), social cards, iOS/Android app ladders, Chrome-extension and YouTube sizes. • Text Overlay — multiline captions with font, size, fill/stroke, shadow, opacity, a 9-point anchor grid and X/Y offset, with a live preview. • Drop a file, click to browse, or drag an image straight off a web page. There's also a right-click "Send image to Toolbelt" option. ■ TERMINAL / MARKDOWN FORMATTER • Paste raw terminal output and get clean, colorized text (ANSI codes converted, not stripped blindly). • Render Markdown — including fenced code blocks with syntax highlighting. • Auto-detect, terminal-only, Markdown-only, and raw modes. • Copy as rich text, plain text, or Markdown; download as .md or .html. ■ CSV VIEWER • Open .csv files in a fast, full-tab table. • Sortable columns, per-column filters, global search, show/hide columns. • Virtualized rows for very large files; streaming parser for big inputs. • Stats panel and export of the filtered view as CSV or JSON. ■ PRIVACY BY DESIGN • All processing is local to your browser. • No host permissions are requested at install. • No analytics, no telemetry, no data ever leaves your device. • The only optional network access (loading an image you dragged from a web page) is requested at runtime, only when you ask for it, and can be revoked at any time. Open Toolbelt from the toolbar icon — it lives in the browser side panel, so it stays open and resizable while you work.
