Made for the interruption

Small tools should not become another big commitment.

Tinapps is a workbench for the jobs between the real jobs: the file that is too large, the two drafts that look identical, the color that almost passes, the timestamp nobody wants to decode, or the payment that needs a second look.

Work, not categories

Follow the job all the way through.

The library is organized by material—text, images, numbers—but the useful paths often cross those boundaries.

  1. 01

    Ship the asset

    From a heavy image to the right file

    Resize it, compress it to a real byte target, convert the format, then check what metadata is still attached.

    ResizeCompressConvertInspect
  2. 02

    Clean the draft

    From rough copy to a confident handoff

    Compare revisions, fix capitalization, measure the final length, and share the exact working state instead of a screenshot.

    CompareTransformMeasureClean
  3. 03

    Settle the numbers

    From a monthly payment to the full cost

    Model the loan, test extra payments, place the result in a budget, and turn the remaining cash into a dated savings goal.

01

The tool opens before the pitch

No landing-page maze, account wall, or onboarding tour. The working surface is the first thing on every page.

02

Private work stays close

Most inputs are handled in the browser, which is where an unreleased image, private draft, token, or financial scenario belongs.

03

The answer explains itself

Useful diagnostics sit beside the result: the failing line, the WCAG ratio, the interest cost, the byte count, or the assumption that changes the outcome.

The whole workbench

Compare, format, convert, count, encode, and clean text.

7 tools

Colors

Contrast repair, OKLCH token scales, gradients, and palettes.

10 tools

Image

Resize, compress, convert, crop, and strip metadata locally.

10 tools

Numbers

Percentages, exact big-integer maths, and dataset summaries.

9 calculators

Finance

Loans, mortgages, compound growth, and payoff strategies.

4 tools

Developer

Cron schedules, regex, JWT inspection, and identifiers.

3 tools

Time

Timestamps, time-zone overlap, and business-day counting.

10 libraries

Reference

Searchable libraries with a page for every record.

4 apps

Learn

Short practice for typing, mental maths, maps, and code.

Questions, answered plainly

Before you paste something important.

Are these tools really free?

Yes. There is no account, no trial, no usage limit, and no paid tier holding back a feature. The tools run in your browser, so there is very little to charge for in the first place.

Is my data uploaded anywhere?

Almost never. Text, images, tokens, and financial figures are processed by JavaScript in the page and are not transmitted. Each tool states what it does with your input, and you can confirm it by watching the network tab or by disconnecting from the network and carrying on.

How do I find the right tool?

Search the directory on this page by what you want to do — 'compress', 'diff', 'timestamp', 'percentage' — and the matching tools appear under the category they belong to. Press / anywhere on the page to jump into the search field.

Do the tools work on a phone?

Yes. The layout collapses to a single column, the tool list moves behind the menu button, and controls open in a sheet. The only exception is typing practice, which needs a physical keyboard to be meaningful.

Can I share what I made?

Each tool encodes its settings in the URL, so copying the link is enough for a colleague to open the same state. Large inputs such as images and long documents deliberately stay on your device — those links carry the settings and the derived result instead.

Who is this for?

Developers, designers, writers, marketers, and anyone with a small job that does not deserve a desktop app or a sign-up form. The tools go deeper than a search-result calculator, but they still open in a second.

What is slowing you down?

Search the library by the job: compress, compare, convert, calculate.
