No data leaves your browser
Craftisle runs tools client-side. Your file uploads, passwords, and API keys never hit a server. The trade-off: large files (100MB+) may be slow or hit browser memory limits. Most tools cap out around 50MB comfortably in Chrome.
What you get without signing up
Free tier includes all 62 tools, unlimited use, no ads in the tool workspace. Signing up adds history, favorites, and custom tool presets — but it's optional.
Three external products worth knowing about
Craftisle also runs three standalone products:
pdfcraft.app — 67 PDF-specific tools. Merge, split, compress, OCR, sign. Built on pdf-lib + PDF.js.
viewer.craftisle.com — Opens 100+ file formats in-browser. PSD, AI, EPS, DWG, RAW photos — all render without the native app.
