These days, when people need to handle a quick task, their first instinct is often "is there an online tool for this," rather than installing an app just for a one-off need. Here are 10 free online tools that come up constantly in daily work and life, spanning calculations, text, images, and development — all of them ready to use directly in your browser.

Want to pull text out of a PDF so you can edit it? This tool extracts the content and turns it into an editable Word document.

Looking up a specific month's calendar or figuring out what day of the week a date falls on is quicker through this tool than digging through your phone's calendar app.
All of these tools are free, require no sign-up, and process everything locally in your browser — so you don't need to worry about privacy. Bookmark this page and come back whenever you need one.
