Free Online Browser tools: Big list of free In Browser, Single Use tools
August 29, 2023 9:15 AM   Subscribe

You need to do a thing - NOW! For when you need to calculate a thing, or look up a thing, or be able to do the thing in your Browser without any faff. Most of the tools listed are NOT from https://freetinytools.com/ but I had to put a link in the description....

As far as I can tell none of the links herein ask you to:
  • Pay for anything
  • Involve A.I
  • Ask you to sign up for anything, or provide and email address
Apologies, they are listed in no particular order

Got a suggestion? Please share with a comment!

Sometimes you just need to be able to Do the Thing, in a browser, without any of the faff (something that takes a lot of effort, for minimal reward, or causes slight problems)

Enjoy.

You're making a request to grab your tool to do a thing, but what if the tool is just... the information you wanted in the first place? Can we go tinier?
  • ip.neolane.net is an IPv4 and IPv6 capable endpoint that returns, in plain text, the IP address of the requestor. Most of the other well-known tools that do this (like checkip.amazonaws.com) are IPv4-only endpoints with no AAAA record, so you will never get your IPv6 address back if you have one.
  • worldtimeapi.org will return the current time and date in a blob of plain text with a bit of tzdata mess, or a neat little parcel of JSON if you chop off ".txt" from the URL. Just pass your TZ string in the URL.

This thing is wonderful, but I did not see my most common conversion: bits to bytes and vice versa.

Our computers live in a world of bytes, yet all the ISPs insist on talking to us in bits. It’s maddening.

Some great resources here, though it's making me pine for the days when bookmarklets were all the rage. I'm weird, and tend to want even meaningless computer transactions happen locally rather than over the internet.

Any other fun (non-nefarious) uses for zero-width spaces? I use them so that I can prevent Facebook from mucking up my text. Say I want to use an old-fashioned smiley: can't do it, they turn :-) into ☺️. But a zero-width space works a charm! Also I like to use lettered lists:
A) my first point
😎 my second
C) my third β€” wtf ^%*&^$*^& facebook!

ics Converter webapp: converts a spreadsheet of events into a digital calendar file

OMG, I had to teach myself to write .ics files by hand several years ago because our in-house Microsoft super geniuses can't or won't put all the university's holidays into every user's calendar (or even make them optionally available).

Now, every autumn when the calendar is released with next year's holidays, I edit my folder full of .ics files to have the new dates and then send them out to the department.

To the IT department, that is, in which I work, who are the very people who can't do this with all their superuser access. *cue exaggerated, theatrical eye-rolling*

https://www.unicodeit.net/

Converts LaTeX expressions to copy/pastable unicode. Not everything works of course but pretty handy if you want to include math stuff in a comment somewhere where Mathjax or similar isn't available.

It's ℝ neat.

If you need specialty graph paper in PDF form, this is a great place to get it.

Also, there's a trick to converting 8-bit binary ASCII into text in your head. If you ever see text (e.g. on a T-shirt or poster or somewhere else) that looks like a bunch of octets where the first bits are almost always 01, it's very likely hiding a message. For example:
01001101 01100101 01000110 01101001

They all begin "01", which is a dead giveaway (things starting with 00 are spaces and punctuation, so you seldom need to worry about those in a message). Just look at the last 5 bits of each one:

01101 00101 00110 01001

If you can convert 5-bit binary to decimal in your head (which takes a little practice but isn't hard to learn), these become:

13 5 6 9

And then the usual A=1, B=2, C=3,... Z=26 encoding gives you:

M E F I

In this case, the "e" and "i" were actually lowercase, but you don't need to worry about that if you're just trying to read a message.

This might be a little bit niche but I found it very handy when apartment hunting : BatchGeo

To use it, you just need a labeled and formatted CSV / XLS file (they have a sample file on the site) and when you upload your file, it will make a custom map with all the data points helpfully pinned on the map.

Sample use cases :
- Do what I did and paste in the address for each property you're looking at. Now you've got a handy-dandy map to plan a route to see them all in one day

- Make a spreadsheet of roadside attractions for your next road trip

- (did this one recently) for a game night with friends, use it to figure out which place is the most "fair to all" to convene at, minimizing travel for all involved

They have a (free) mobile app for iOS (iPhone and iPad), and shareable links as well. Might not be quite the "tiny tool" but I thought I'd pass it along cause it's really quite neat.

Great list, but I want to note that 12ft.io works for me much less than it used to. For a recent site I tried (theathletic.com) it served me a page that simply said "12ft has been disabled for this site", which sounds to me like a payoff.

Epoch Converter

Because I live the "WTF is that log timestamp, even?" life as well, I have years and years of reflexive motor memory for the GNU date command to do this easily: date -d @1693348075

On a BSD userland such as macOS, with its more bizarre syntax, it's a lot fussier and I have to look it up every time: date -j -f"%s" 1693348075

Or, in reality, just use gdate

Maybe the tiniest tools are the ones you already have in your hand?

Here's a bunch of front end / accessibility-focused ones:
  • Browser Default Styles shows you the default styles used for the HTML element of your choice in popular desktop browsers.
  • Can I Use details browser support for all manner of things: CSS, JS, HTML and more.
  • CanInclude is for answering the question "Can I legitimately include this HTML tag in that one?"
  • RGB to Hex colour converter does what it says on the tin. So does Hex to RGB.
  • WebAIM Contrast Checker lets you make sure your text is sufficiently high-contrast against its background to be legible.
  • Who can use this colour combination? tells you and shows you roughly how usable your colour pair is for people with various forms of colour blindness... and people working in direct sunlight, and people using Night Mode.
