Online photo resize comparison V1.0

Published by:

Ever wanted to quickly crop or resize an image? If yes, then you probably tried online tools, because you didn’t want to install anything. I’ve been installing some tools, but whatever I tried, it always resulted in endless loading or missing features.

So, what am I looking for then?

I’m looking for a quick solution to resize and crop. I need something to easily input the chosen dimensions or to freely select a crop area. It has to load instantly, take files or URL’s, easy to use and somewhat nice to look at.

My top 3

rstool_webresizer is a very quick and usable online resizer. It’s very easy to input the dimensions for resize or crop. As an extra bonus, the pictures are optimized to use less bandwidth without loosing quality. It even sharpens images.
rstool_2 is only for cropping, but is very good at it. It’s lightning fast. If you are impatient, just like me, then this one is for you.
rstool_3 Does both cropping and resizing. Users can quickly choose a stardard size or input a custom size. As a bonus the app does some tweeking (contrast and sharpness). It can rotate and it allows users to change the output quality. Still this tool is fast.

I have made a small list of online tools I checked out today. There are many more, but the ones listed here are fairly common.


Preset crop: the ability to choose from a list of predefined cropping area’s
Free crop: the ability to draw a rectangle of the cropping area
Custom crop: the ability to input exact dimensions of the cropping area
Preset resize: the ability to choose from a list of predefined sizes
Free resize: the ability to skew or stretch freely with the mouse
Custom resize: the ability to input exact dimensions
Rotate: ability to rotate
Extra features: this indicates that it is possible to change the pictures, add effects or do other things
Upload image: the ability to upload an image from you harddisk (upload it to their servers)
Import URL: the ability to import the URL of an existing online image, they will download it for you into the application
Speed: This indicates how fast the program loads and operates (not counting the upload) good or bad
Quality: This indicates the resulting quality ( this needs to be checked further )
Usability: This indicates if the application is intuitive, logical, straight forward and easy to use

More features

I selected one of the online apps that had a lot of features.

rstool feat 1 has many features, such as framing, adding text, painting, sharpening, rotating.. and resizing!!

Fototoestel aan een ballon op 36 km hoogte

Een foto genomen op 35,8 kilomenter hoogte tijdens een experimentele ballonvlucht BEAR (Balloon Experiments with Amateur Radio):


In augustus hebben een groep radioamateurs een met helium gevulde ballon waaraan ze een doosje met een radiozender en een Nikon Finepix hadden bevestigd gelanceerd. De camera was zo ingesteld dat ze één foto maakte per minuut. Tijdens de vlucht konden de radioamateurs de positie van de ballon volgen via een klein zendertje dat ze bij de camera hadden ingebouwd. Het was aangesloten op een GPS ontvanger en zond de positie door via 144Mhz. Na ruim 2 uur bereikte de ballon zijn hoogste punt op bijna 36 kilometer en barstte de heliumballon. De camera kon met een parachute terug op Aarde landen, waarna de foto’s konden bekeken worden.
