5 Tiny, Free Web Tools That Do Just One Job Perfectly

Most modern software wants to be everything to everyone. Your email client now has an AI calendar, your document editor wants to manage your company payroll, and every website you visit insists you create an account, verify your email, and sign up for a weekly newsletter.

That is why discovering a single-purpose web tool feels like discovering an oasis in the desert.

These are tiny, hyper-focused utilities created by generous developers that do exactly one task with zero friction: you paste something in, it does the job in three seconds, and you leave. No account required. No credit card popup. No onboarding tour.

Here are five of our favorite free web gems that deserve a permanent spot in your bookmarks bar.

1. Squoosh (squoosh.app)

What it does: Shrinks images by 70% to 90% without visible quality loss.
Why it’s great: Built by the Chrome team, Squoosh is completely free and processes everything locally in your browser (your private photos are never uploaded to a cloud server). It features a brilliant interactive slider that lets you visually compare the original photo against the compressed WebP or AVIF output in real time. Perfect for blog posts, email attachments, and web uploads.

2. Diffchecker (diffchecker.com)

What it does: Visually compares two pieces of text, code, or documents and highlights every difference.
Why it’s great: Ever receive a revised contract, a long email draft, or a spreadsheet update and wonder, “What actually changed between version 1 and version 2?” Paste both versions side-by-side into Diffchecker, and it instantly highlights every added, deleted, or altered word in green and red. It saves hours of manual squinting.

3. CleanURL / URL Cleaner (cleanurl.org)

What it does: Strips messy tracking parameters (?utm_source=..., &fbclid=..., &ref=...) from shared links.
Why it’s great: Modern web links have become ridiculously long, bloated strings of alphanumeric tracking codes. Paste a long, ugly product link or social share URL, and CleanURL returns a pristine, minimal link that is clean to read and safe to send to colleagues.

4. ILovePDF (ilovepdf.com)

What it does: Splits, merges, compresses, and rotates PDF files in seconds.
Why it’s great: Adobe wants to charge $20 a month simply to combine two PDF receipts into one file. ILovePDF lets you drag in three files, rearrange the pages with your mouse, and download the merged document instantly. It handles 95% of everyday PDF headaches without opening desktop software.

5. Hemingway Editor (hemingwayapp.com)

What it does: Highlights dense, complicated, and hard-to-read sentences in your writing.
Why it’s great: Whether you are writing an email to leadership, a proposal, or a blog post, we all fall into the trap of writing overly complex run-on sentences. Hemingway highlights wordy phrasing in yellow and hard-to-read sentences in red, forcing you to write with punchy, crisp clarity.

The Joy of Simple Software

In an internet increasingly crowded with heavy enterprise platforms and mandatory logins, single-purpose utilities remind us of what made the web magical in the first place: simple tools built to solve human problems quickly.

Bookmark a few of these, save them for a rainy workday, and pass them along to that friend who still spends twenty minutes manually combining PDF files!
