ToolAnchor

什么是 ToolAnchor？

ToolAnchor is a free collection of 200+ online tools: merge and compress PDFs, convert HEIC/WebP images, remove backgrounds, trim videos, count words, format JSON, and dozens of calculators. Unlike most "free" tool sites, everything runs entirely in your browser using WebAssembly — your files are never uploaded to a server. No sign-up, no watermarks, no daily limits. Works offline as an installable app.
