Best Free Online Applications and Services


Best Free Online Applications and ServicesOnline applications (also known as web applications or webware) are getting more popular, particularly when broadband Internet access has become more common and readily available to more users. With online applications and services, you do not need to download and install them into your computer for using them—you just need to open up a browser and access them online.

Not only that you can save harddisk space as they do not need to be installed, but also you can work with files that are saved online from any computer anywhere, without the need to carry a storage device even a USB stick around with you.

Besides, you don't have to worry about different operating systems as these applications and services are cross-platform, running in your browser as a client. Neither do you need to keep updating your software versions, as you will get any new software updates and bug fixes automatically whenever you access them.

Like to use them? Here we have compiled a list for best free online applications and services—click on related links or product logos and you can start using them right away.

Nice article. Thanks.

I think you could also add , a knowledge engine(they say)
I had found it useful a lot of times.
I also found sumopaint better than pixlr

by Bob on 18. January 2010 - 7:22  (41407)

Yes, very nice article in the making!

Another suggestion:
LinkExtend - For the Internet Safety category; though it also provides ready access to useful site statistics.

You should add Grooveshark in a "music streaming" category. It's like Spotify, but has users uploading music from their computers instead. Don't worry, it's just as legal as Spotify.

by Jojo Yee on 4. February 2010 - 3:58  (42744)

Appreciated your kind suggestion.

by Jojo Yee on 4. February 2010 - 4:34  (42746)

Thanks for mentioning WolframAlpha, an innovative answer engine which is worth a try.

by MidnightCowboy on 5. February 2010 - 13:48  (42883)

Is this any good?
(Apologies if it's already here somewhere)

by Jaikrishna on 6. February 2010 - 8:01  (42933)

I too suggest SumoPaint instead of Pixlr.
It has got a lot more options than Pixlr.

by Jojo Yee on 6. February 2010 - 9:23  (42939)

Thanks for the good suggestions. Added in the list.

I think you could also add online vulnerability checker tools
(which determine whether a system is infected or not by scanning vulnerable areas)
But, I don't know which one is the best.
I think Symantec's is good.
Please check
Go there and click Continue to Symantec Security Check

Thanks for the pointer. I'll give it a try.

Today Cacoo website went down for sometime (I don't know the reason)
During that period this page was loading for ages.
That was because, it was trying to get its logo from Cacoo website (which was down)
I think this problem can be solved by moving the images to
(That was how it was done in other articles)

by Jojo Yee on 9. February 2010 - 9:03  (43148)

The Cacoo site is up now at this time. Its product logo shown in this article is now hosted on TSA.

I think Mozy beats Dropbox hands down for online backup. You get 2GB of free online backup that you can encrypt with your own password. It doesn't compete in the sync department yet, but I hear that Mozy is contemplating adding a sync feature in the future.

Mozy Free 2GB of Backup

Great article:

I'd suggest Time and Date as a good Time Zone or Date service. Includes many options and has extensive list of world cities. Check it out:

This raises a question in my old brain: what will happen to program-makers and vendors if all programs end up in the "cloud." A silly question I think, but I don't understand this new cloud concept too well! Bob B.

LinkExtend in combination with WOT can go a long way toward preventing one from going to a bad site. I have used them in combination for about a year and have yet to have a problem with any site.

Great list! I already use a bunch of these apps and services; now I'm excited to check out more.

I would campaign for Evernote to be added to the "Notebook" category--either alongside Zoho or in place of it.

I suppose it's not exclusively an online program, since there is a local app (that syncs seamlessly!), but the online version works just fine as a stand-alone.

Anyway, I really like it, and I thought some of you might too.

by jmaloney on 10. February 2010 - 21:28  (43308)

Thanks for the list!

I would add Google Search to the section "Unit and Currency Converter". I frequently convert units in the Google search box just by typing things like the following

41 degrees C in F
3.35 Euros in USD
48 sq m in sq ft
115 g in oz
MXVII in decimal

You don't even have to hit enter. Just type it in the Google search box and your answer is shown automatically.


by jmaloney on 10. February 2010 - 21:36  (43310)

In fact, the Google search box provides a lot of quick online services, including: time, weather, stock quotes, sports scores, synonyms, definitions, spell checking, package tracking, and many more. There's a list here:

A few online calculators and math solvers

Ecalc online

Moderators comment: As far as I can see, Ecalc offers nothing that windows calculator doesn't already have. The scientific mode offers only a link to a trial version download with no information regarding the terms of the trial. Not all of the free downloads have a freeware license so be sure to read what you are agreeing to if you install any of them.

The Dropbox links take you to Skydrive, the links need fixed.

by Jojo Yee on 11. February 2010 - 3:26  (43351)

Thanks for the heads-up. The link has been fixed and it will take you to the log-in page of Dropbox now.

by Jojo Yee on 11. February 2010 - 9:09  (43366)

Instacalc looks good. Thanks for the suggestion.

Cloud Computing is a solution looking for a problem.

Unfortunately for the people that support this 'idea', big business doesn't have a problem. Entrusting vital data to some third party may at best be risky, and depending on where you live, illegal. Businesses and individuals within the UK should seek legal advice regarding such arrangements.

There have been numerous cases, big and small, in the last year and a half where data entrusted to 'The Cloud' has been lost, hacked, or stolen.

I may not be a world ranking security expert. but if anything is stolen from my home network I have nobody to blame but myself.

Like square wheels, hopefully it will run out of steam.

Thanks for your kind comments. Evernote is now included in the list.

Depends on how you use it. I use Internet banking, i.e. cloud computing, with no issue.

by Jaikrishna on 16. February 2010 - 4:57  (43716)

Please see ezyZip at
It uses a java based application on local computer for faster Zip and Unzip.
It is very fast and there is no size limit.

Dropbox has 2GB free aswell! AND it syncs to pcs..

I have to suggest PIKNIK for photo editing, whith it tie in to picasa and flikr among other photo hosting sites and its sheer ease of use its the best I have used.

by Anonymous on 19. February 2010 - 13:24  (43954)

I've Java installed (version 6 Update 18). When going to ezyZip, encountered errors:

"The publisher cannot be verified by a trusted source.
Code will be treated as unsigned.

Name: Zipper Response is unreliable: its validity is out-of-date."

After clicking OK, encountered errors again:

"The application failed to run."
