Shrinking 100 Image Files

There are lots of reasons why someone would think about shrinking image files. The one which comes to my mind, is so that people with Gmail accounts can see them when I send them! I recently bought a new phone, and took some pictures. As it happened, the default setting on the phone, was to take high resolution photos. So, after a day out, I had a bunch of glorious photos, which also happened to be huge.

Now, I know from experience that if you receive a giant photo in Gmail, it’s quite annoying.

For some perfectly good reason (that I don’t know or understand), the giant photos mess up Gmail’s proportions. You can only see part of the picture, and the horizontal scroll bar goes crazy (it gets huge). The reply button, along with the star and the reply options go off screen, never to be seen of again (well, you get the picture – pun intended!).

Anyway, so it’s at that point that I though… “well, lucky me! I know just how to solve this problem!”

The Fix

ImageShell’s Resizer makes it very easy to solve this problem. You just stick the files in one folder, you tell it what output size you want, and click on the resize (“play”) button! It doesn’t matter if you have one or one thousand photos! They all just pop out in the output folder. You can tell it to shrink all the photos by a percentage if your case was like mine. Alternatively, if you want them shrunk for some other reason, you can specify exactly what size you want in pixels. If you want to change the proportions, you can do that too, squeezing or expanding the picture.

And the best thing? Shrinking image files is so simple… Resizer, though very powerful, is extremely easy to use. Easy as pie in fact…

8 Graphic File Formats And the PDF

Here’s a small post about the various file types that ImageShell Resizer (ISR) handles. This list includes the most popular formats on the internet, along with a handful of lesser known formats. The list is in alphabetical order, starting with the BMP.

BMP (Bitmap)

The BMP was developed by Microsoft in the 80s and was at one point quite a popular graphical file format. In recent years though, the BMP has lost its allure, particularly on the internet, due to its size. Of course, it is still in use on every Windows machine, meaning it’s unlikely to disappear anytime soon. However, online, its usage is quite low, currently at 0.2%.

More details can be found here.

GIF (Graphics Interchange Format)

GIF files are also from the 80s, developed this time by CompuServe. The GIF is a file format which at this time, is significantly more popular than the BMP. It’s use on the internet is at around 27%. The popularity of the GIF has also been going down on the internet. At the start of this decade, its use was very close to 70% online. So, though 27% is much, much higher than the BMP, there’s a significant downward trend. Having said that, GIFs have another strength, in that they can be short animations. As such, they are very popular on some social media platforms (e.g. Twitter).

JPEG/JPG (Joint Photographic Experts Group)

The JPEG/JPG format, is one of the most popular of pure graphics formats (the first in photography, and second only to PNG files on the internet). Originally conceived by the organisation of the same name, it has its roots in photography, and is now the primary file used in digital photography. Needless to say, it’s also one of the biggest players on the internet with over 70% of all sites on the internet using it.

It’s a compressed format, so that the size of the a JPG file as opposed to a GIF or BMP will generally be smaller. However, it should also be noted that compressing an original image into a smaller JPG will result is some loss of the quality (something which does not happen with many other formats, e.g. PNG or GIF).

PBM/PGM/PPM (Portable BitMap, Portable GreyMap, Portable PixMap)

These three file formats were all created by Jef Poskanzer in the 1980s. The first of the three, was the PBM which was created so as to be able to send graphics over the networks of the time without the file getting corrupted. The result is that the graphics held in PBM files are visibly very basic. Later, PGM and PPM were developed. The graphics held within these files are higher quality, though it should be noted that PGM, like PBM is black and white.

More details here on the PBM, PGM and PPM.

PDF (Portable Document Format)

The PDF is now world famous. It’s not really a graphics format as the ones above are, however, it can hold graphics. Its main strength is its reliability along with its popularity. You know that when you send a PDF, what you see is exactly what the recipient will see. You also know that the recipient will be able to open the file! For that reason, people do often convert their graphics to PDF files. It was originally developed by Adobe in the nineties, but Adobe subsequently made it an open format, handing control over to the International Organisation for Standardization (ISO).

More details can be found here from Adobe and from the ISO.

PNG

The PNG is currently the most popular graphical file format online at 74.8%. There is no single reason for this, and the popularity is actually, extremely close to that of the JPG. However, one notable difference is the way PNGs can handle transparency. For example, for logo design, PNG is the only way to go, since it will give you a file which looks like it’s not a square (or rectangle). JPGs (or GIFs or BMPs) simply can’t do this.

TIFF/TIF (Tagged Image File Format)

The TIFF was created by a company called Aldus (which was later bought by Adobe), again in the 1980s. TIFF files became very popular in the early internet/desktop computing era, for scanned files, faxing and publishing in general. Like the GIF, a TIFF can also contain numerous graphics/pages. On the internet, its use is very low, at under 0.1%. However in the realm of publishing (e.g. where you might want to use CYMK rather than RGB), TIFF is still commonly used.

Coming soon: ImageShell Resizer

Dear Readers,

Welcome to our site!

We are a small team of developers with a passion for images, image handling and image manipulation. We are about to launch the beta version of what we hope will be a useful piece of software which will be able to resize, crop, rotate and convert (format-wise) images. You’ll be able to download it for free with no time limits, advertising, or other annoyances and use it for any purpose, personal or commercial.

We would love to hear from you with any feedback and just as importantly, if you have any suggestions for imaging tools that you would like to see in our next software. If you have been looking for Open Source or free software to carry out some imaging task but can’t find it out there, please let us know and if we get enough demand, we will endeavour to include it among the capabilities of our next software, which we hope to make available for free as well.

Thanks for visiting, and if you think there are imaging software needs we can help you with, please don’t hesitate to get in touch!

All the best,

From everyone at ImageShell
