Before you upload your next web
image or product picture — a logo, or banner image to your website, think about
the quality and file size of the image. You do not want to make the mistake of
uploading a generous file size.
Not optimizing web images
properly results in extremely slow loading time. When you intend to publish
your images online, you have to compromise the quality. In order to do so, a
good balance between image quality and image file size will be needed when you
save web images.
Here are 3 tools to optimize your
images.
Tiny PNG
Tiny PNG is my go-to image optimization tool of choice.
TinyPNG uses smart lossy compression techniques to reduce the file size of your
PNG files. By selectively decreasing the number of colors in the image, you can
bulk upload images with drag and drop (up to 20 at a time, 5 MB max each).
Results: 660 KB to 236 KB (minus
64%)
Compressor.io
Compressor.io is another one of
my favorite image size optimization tools for one very good reason: It allows
you to choose between lossy (picture quality reduction) and lossless (same
picture quality) compression. Lossless compression, however, is limited to JPG
and PNG images, and the file savings are also typically very small.
Still, the option is available
should you want it, and it’s one that none of the other tools offer, save one.
So if you often have to use both lossy and lossless compression then
Compressor.io is probably the way to go.
It doesn’t allow you to bulk
upload images, though, and the single file sizes are limited to 10 MB.
Results (lossy): 660 KB to 370 KB
(minus 44%)
JPEG Optimizer
JPEG Optimizer does really well
at decreasing file size, but unfortunately the compressed image’s quality is
noticeably lower than the original. Furthermore, the interface only allows you
to upload and compress one image at a time, which makes it unfeasible for bulk
image compression.
Result: 644 KB to 16.7 KB (minus
97.4%)
