10 Free Browser Tools That Save You From Installing Software

There's a specific kind of friction in downloading a full desktop application just to do a five-minute task once. A new install, an account you'll forget the password to, sometimes a subscription you didn't mean to start. For most everyday file and document tasks, a browser tab is genuinely enough. Here are ten common ones.

1. Merging PDFs before sending them

Combining a few reports or scanned pages into a single PDF before emailing is one of the most common small tasks there is — and one of the least deserving of a software install.

2. Converting a PDF to an editable Word document

Whether you need to update an old contract or edit text from a report someone sent you as a PDF, converting back to an editable format is usually a one-time need — not something worth installing dedicated software for.

3. Shrinking a photo before uploading it somewhere

Most upload forms have a size limit, and most phone cameras produce files well over it. A quick compress avoids the "file too large" error without needing photo-editing software.

4. Generating a strong password

Reusing the same password, or a slight variation of it, across accounts is one of the most common security mistakes people make — usually because coming up with a genuinely random one on the spot is annoying. A generator solves this in one click.

5. Making a QR code for a link, WiFi network, or contact card

Restaurants, event flyers, business cards — QR codes show up everywhere now, and generating one takes seconds, not a design app.

6. Converting a PDF's pages to images

Useful for pulling a diagram or a single page out of a longer PDF to drop into a slide deck or a message, without needing a screenshot tool or PDF editor.

7. Formatting messy JSON

For anyone who works with APIs or config files even occasionally, a one-click JSON formatter saves the trouble of manually adding line breaks to a wall of unformatted text.

8. Checking word count on a draft

Word processors bury this in a menu; a dedicated counter shows it live as you paste or type, along with character and reading-time estimates.

9. Converting units without doing the math yourself

Recipe in the wrong measurement system, a spec sheet in units you don't use — a converter is faster and more reliable than doing the arithmetic by hand.

10. Splitting a large PDF into separate files

Pulling one chapter, one invoice, or one section out of a larger PDF without needing to learn a full PDF editor's page-management tools.

None of these need a download or a subscription to try, and every one is free. Everything here — including the file-based PDF and image tools, not just the calculators and generators — works with no account at all, up to a generous free daily use limit. Nothing here needs a software install, and nothing here costs anything to try.
