Eight everyday headaches get shorter answers

Version 1.3.0

HandyPebble now covers practical date math, time zones, cooking, countdowns, PDFs, QR codes, text changes, and file checks—without turning a quick job into a software project.

Dates & time

Business Day Calculator handles workdays and observed federal holidays, while the Time Zone Planner finds realistic meeting overlap across cities.

Kitchen & plans

The Cooking Converter knows that a cup of flour is not a cup of butter, and the Countdown Maker keeps important dates on your own device.

PDFs & QR codes

PDF Toolbox organizes pages and builds PDFs from regular images or iPhone HEIC photos. QR Code Studio creates or scans codes without automatically opening mystery links.

Compare & verify

Text Diff Checker finds changed lines, words, or characters, and File Checksum verifies downloads with SHA-256, SHA-384, or SHA-512.

Local by default

PDFs, images, text, and files are processed in the browser. The tools do not upload the material you open.

Built to come back to

Useful preferences stay on the device where it saves time. Sensitive content and one-off source files are not turned into accounts or cloud projects.

The next holiday gets a proper countdown

Version 1.2.1

The new U.S. Holiday Calendar puts major American dates into a familiar monthly view and keeps the next celebration ticking by the second.

Live countdown

See the next holiday with separate days, hours, minutes, and seconds, plus always-visible Thanksgiving and Christmas countdowns.

Dates with context

Federal holidays, popular observances, and nearby observed federal days are labeled separately instead of being tossed into one vague list.

Calendar-ready

Open any holiday for a plain-English explanation, then download a standard event file for Apple Calendar, Google Calendar, or Outlook.

Remembers your view

The last month, year, and filter stay on the device and update automatically the next time a different view is chosen.

Period planning gets privacy and honest limits

Version 1.2.0

The new Period Calculator estimates upcoming cycle dates without asking for an account or saving personal dates.

Quick forecast

Enter a last period, average cycle length, usual period length, and typical variation to see the next six expected cycles.

Calendar view

A three-month calendar marks estimated period days, fertile windows, ovulation dates, and today in one clear view.

Useful takeaway

Make a private planning PNG that keeps the estimate and its safety statement together.

No false promises

The page states clearly that calendar math is not birth control, pregnancy confirmation, diagnosis, or medical advice.

Private details get a paintbrush

Version 1.1.9

The new Mosaic & Blur Brush hides faces, plates, addresses, and screenshot details without sending a photo to the cloud.

Two useful effects

Paint strong mosaic pixels or a softer blur, then use Restore to bring original pixels back over a mistake.

Mixed on purpose

Every stroke keeps its own effect, strength, size, and feathering, so one photo can use different treatments in different places.

A practical batch

Edit up to 12 photos, keep separate undo histories, download one result, or package the whole group into a ZIP.

Still local

Opening, painting, previewing, and exporting happen inside the browser. The selected photos never get uploaded.

The car deal gets unpacked before the payment

Version 1.1.8

The new U.S. Auto Loan Calculator starts with the amount financed, then shows the monthly payment and total interest without hiding the trade or old-loan payoff.

Nationwide starting point

Choose any state or Washington, D.C. to load a state-level vehicle tax starting point and an editable trade-in tax setting.

Trade math included

Positive trade equity reduces the new loan. Negative equity is called out clearly when an old payoff gets rolled forward.

Term cost made visible

Compare APR and terms from 36 through 84 months, with total interest and a yearly payoff table beside the monthly number.

Clear limits

State and local rules vary, so the page labels its result as a planning estimate—not a dealer worksheet, lender quote, or tax advice.

August 22, 2026

The house payment gets the whole story

Version 1.1.7

The new U.S. Mortgage Calculator estimates more than principal and interest, so the monthly number has fewer expensive surprises hiding behind it.

Whole monthly estimate

Add property taxes, homeowners insurance, HOA dues, and PMI alongside the fixed-rate loan payment.

Down payment, both ways

Enter dollars or percent and the other value stays in sync, with the resulting loan amount always visible.

Long view

An annual amortization schedule shows how much goes to principal, how much goes to interest, and what balance remains.

Honest assumptions

The calculator does not invent a PMI charge or pretend to fetch a live interest rate. Every important assumption stays editable.

The cutout can bring its own background

Version 1.1.6

The Freehand Image Cutout can now save a high-quality JPEG when transparency is not what you need.

Two honest choices

Transparent PNG remains the default. Choosing JPEG changes the preview, file name, format, and both download buttons together.

Soft color slider

The JPEG background starts at white and moves through eight restrained macaron colors for quick product shots, cards, and posts.

No mixed-up files

JPEG mode only downloads JPEG. Switch back to Transparent PNG whenever you need the removed area to stay transparent.

Still local

Background compositing and export happen inside the browser. The original image never gets uploaded.

August 22, 2026

Odd shapes get a clean exit

Version 1.1.5

The new Freehand Image Cutout lets you trace the exact part of a picture you want and save it as a transparent PNG.

Draw it yourself

Use a mouse, pen, or finger to draw one closed outline. Nothing tries to guess which subject you meant.

Fix the outline

Add or remove small areas, undo the last correction, and zoom or move the image when an edge needs a closer look.

Softer edges

A simple feather control smooths hand-drawn bumps, while optional auto-trim removes unused transparent space.

Stays local

The image is traced and exported inside the browser. No upload, account, watermark, or saved copy.

August 22, 2026

A familiar calculator joins the shelf

Version 1.1.4

The new Classic Calculator handles everyday arithmetic and percentages without hiding the useful buttons behind a mode switch.

Familiar layout

The number pad, four basic operations, percentage, sign, decimal, clear, and delete controls sit exactly where you expect them.

Keyboard ready

Number keys, operators, Enter, Backspace, and Escape work alongside the large touch-friendly buttons.

Percentage behavior

Use % on its own to divide by 100, or use it with addition and subtraction to calculate a portion of the first number.

No saved tape

The calculation stays in the open page and disappears when the page is refreshed or closed.

August 22, 2026

The saved tab finally has a face

Version 1.1.3

HandyPebble now has a proper little yellow pebble in browser tabs, bookmarks, phone shortcuts, and installed web apps.

Easy to spot

The simple black H stays readable even when the icon is squeezed down to 16 pixels.

Browser ready

Modern SVG and PNG icons sit alongside a multi-size ICO fallback for older browsers and saved bookmarks.

Phone friendly

An Apple touch icon and web app sizes keep home-screen shortcuts from falling back to a random page screenshot.

Everywhere

All public pages now point to the same icon set, so the toolbox keeps one recognizable face from page to page.
