Practical how-tos that turn what you want to do with images, PDFs, and privacy into clear steps and tips using free tools.
Toolish Guides are practical how-to articles that go alongside our free tools. Each guide is a complete, self-contained read: it explains the background of a task, walks through the exact steps, shares tips for better results, and answers common questions in an FAQ — so you can learn what you need without hunting across pages.
Every tool featured here runs in your browser, most of them fully on your device with nothing uploaded. The guides cover images and photos, PDFs, privacy, and learning games, and each one links to the free tool it describes so you can try it right away.

The guides are grouped by the kind of task they help with. Whether you want to protect your privacy before sharing a photo, tidy up a document, or turn a few minutes into learning or brain training, here is what each theme covers.
Remove EXIF and GPS location data before posting, blur or mosaic faces, remove a photo's background, extract text from an image with OCR, or pull a color palette out of a picture. These guides focus on getting a clean, safe-to-share result — and explain why each step matters, not just how.
Merge, split, reorder, rotate, and redact PDF pages, and send a large file securely with a one-time link. The guides explain the difference between operations like masking and true redaction so you don't accidentally leave hidden text behind.
Learn katakana with a memory game, teach kids to count money by paying with coins, train focus with a Schulte table, sharpen observation by spotting the odd one out, or get moving with a jump game. Each guide explains what the game trains and how to get the most out of it.
