We’d like to bring to your attention 3 forgotten wonderful image processing tools. They are quite old but are extremely lightweight, terribly effective and best of all – they are absolutely free.

Mac users – sorry, these are Windows applications…

I believe the guys who developed them follow the principle: “If it is working, don’t touch it!” because they haven’t been developed further for a long time.

All of them just do what they are intended to. Nothing more, nothing less. Moreover they do it very fast, with minimum resources and high quality results.

We will present you Caesium, JPEGCrops and VisiPics.

1. Caesium

Caesium is an image compressor. It is invaluable tool for webmasters, web designers and everyone sharing images across the Internet. According to the developers it can compress pictures up to 90% without visible quality loss and we tend to believe it.

The interface is very intuitive and simple. There is no point to show step-by-step screenshots here. You can figure out how it works just at a glance.

The screenshot shows our test result. We compressed 57 images of total 68.3 MB in less than a minute (55.76 seconds). Caesium reduced their total size on disk to 21 MB (yes, 3 times!) without losing any visual quality.

The screenshot itself was compressed with Caesium from 336kB to 207kB in 0.52 seconds.

Features:

  • Up to 90% compression without losing any visual quality.
  • Process files in batch mode. You can open entire folder and even include the sub-folders.
  • Resize option. You can resize either in pixels or percentage, keeping or not the aspect ratio.
  • Custom suffix of the compressed files if needed.
  • Comparison preview of original vs compressed pictures.
  • View details using the zoom function.
  • Support for common file formats.
  • Standalone installation or portable version.
  • Multi-language support.

With its 21.90 MB portable version and 15.32 MB Windows installer, it is the “heaviest” of all three tools presented here.

Caesium is compatible with all Windows versions. Its last update was in 2013 but the software does its work perfectly.

Conclusion: Very fast and lightweight. Worth to try it.

2. JPEGCrops

Do not mix it with Jpeg Club’s Jpegcrop (without letter “s” at the end of the name) Windows Application. Jpegcrop is another freeware image processing software which we will present in a future post.

JPEGCrops is very easy to use application for cropping images. It allows both separate or batch image processing. There are many predefined and a free (user defined option) aspect ratios. The software allows also flip and rotate the images.

There are bunch of applications doing cropping. The advantage of JPEGCrops is that the program is extremely lightweight and intuitive to use. The installation .exe file is only 795kB and needs max. 2.5MB on the hard disk and the portable version download zip is 781kB (1.85 MB decompressed).

The software has multi-language support.

Its last update was in 2006 (!) but the software does its work perfectly.

Conclusion: Does exactly what it is intended to do – to crop images in pre-defined or custom aspect ratios – single or in batch. Worth to try it.

3. VisiPics

VisiPics is not exactly an image transformation program but it is very useful for every huge pictures collection.

Everyone has collection of pictures. It grows during the years, sometimes the pictures are stored twice in different locations, sometimes we saved a picture again in higher resolution – the ways you can get a huge “collection” of duplicate pictures are quite a lot.

VisiPics finds duplicate pictures. Yes, there are many applications – commercial or free doing the same. But VisiPics has the advantage to be extremely tiny – the Windows Installer is only 2.11 MB and the installation takes 5.7 MB on hard disk; and – it’s free.

Some features:

  • Great speed – 6 pairs of duplicates found in 185 for just 1.44 min.
  • As per developers it was tested on a 100,000 pictures (15 GB) archive which was processed in 3 hours.
  • It can detect:
    – two different resolution files of the same picture
    – the same picture saved in different formats
    – the same picture saved in different folders
    – duplicates where only minor cosmetic changes have been made
  • Searches for duplicate images using three different filters:
    Strict filter returns images with no difference
    – Basic – more loose than strict – slight/ minor differences
    – Loose – returns groups of images with much more differences (be careful with it)
  • “Auto-Select” feature – marks images with smaller, uncompressed, lower resolution copies as duplicates.
  • Works with most widespread formats: JPEG, GIF, PNG, BMP, PCX, TIFF, TGA and RAW images.
  • Intuitive, user-friendly interface.

Warning using VisiPics:

Besides the file name and size comparison, the software uses advanced algorithms which make it extremely precise.  The filters are so sensitive that the program reacts to such minor differences as picture angle or lighting variation.  Thus, you should be very careful when deleting images in case you want to keep slightly different files.

Luckily there is an option of moving the duplicates in different folder without deleting them.

Another good thing is that the deleted images are moved to the recycle bin and are not deleted permanently. You have time for consideration indeed…

The latest version 1.31 is from June 20, 2014 but thew program maintains its exceptional performance.

Conclusion: Very good and lightweight program with intuitive user interface. Has the most necessary options without useless extras. Highly recommended.
