The unit converter gets a proper accuracy pass

Version 1.4.1

The Unit Converter now keeps the side you are typing from in charge, remembers changed unit pairs correctly, and catches impossible temperatures.

Both directions behave

Type on the left or right, then change a unit. The converter continues from the value you were actually editing instead of silently switching sides.

More clearly labeled units

U.S. and Imperial liquid measures stay separate, while MB and MiB remain visibly different. Nautical miles, short tons, square miles, cubic units, and TiB are now included too.

Absolute zero has a boundary

Values below 0 K now show a plain warning instead of producing a physically impossible result.

Sixteen useful jobs get their own short route

Version 1.4.0

The toolbox now reaches well beyond images, with focused tools for documents, security, math, time, writing, design, small business, and everyday decisions.

Documents & security

PDF to JPG or PNG exports selected pages, while the Password Generator creates secure random passwords or readable passphrases without sending either one anywhere.

Math for real life

Scientific Calculator, Percentage Calculator, Tip & Split Calculator, Discount Calculator, and Exact Age Calculator answer five different questions without mixing them into one crowded page.

Time & words

Timer, Stopwatch & Alarm handles ordinary clock jobs, the Pomodoro Focus Timer structures work rounds, and Word Counter & Text Cleaner counts and tidies text locally.

Pictures that explain

Image Collage Maker frames up to 12 photos, and Screenshot Annotator adds arrows, boxes, highlights, notes, and pixelation.

Everyday decisions

The Unit Converter keeps U.S. and metric measurements together, while the Random Picker gives names and choices a fair spin.

Small-business basics

Invoice Generator creates a print-ready bill without an account, and Barcode Generator makes common UPC, EAN, Code 128, Code 39, and ITF artwork as SVG or PNG.

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.
