Many App Store and Google Play games feature high-quality screenshots
that load almost instantly. Minimal waiting time for the potential customer,
while maintaining perfect visual clarity. Why do they load so much quicker
than my Photoshop PNGs?
Answer: clever image compression—and there are a number of good tools
out there that are designed to minimise image size without compromising
on image quality. Good news for cash flow too: these tools are all free to use.
Compressor.io is a powerful online tool for reducing drastically the size of
your images and photos whilst maintaining a high quality with almost no
difference before and after compression.
The following file formats are supported—JPEG, PNG, GIF and SVG, and
there are two types of compression, lossless or lossy.
Smush.it uses optimization techniques specific to image format to remove
unnecessary bytes from image files. It is a ‘lossless’ tool, which means it
optimizes the images without changing their look or visual quality.
You can enter multiple image URL addresses from your site, and Smush.it
will report how many bytes would be saved by optimizing the images.
Handily, it will then provide a downloadable zip file with the minimized
You can also upload images to compress, which can then be downloaded as a zip archive.
Optimizilla allows you to upload up to 20 files in JPEG and PNG formats.
You can then use the slider to control the compression level and download
the results. Optimizilla uses a smart combination of the best optimization
and lossy compression algorithms to shrink an image file to the minimum
possible size while keeping the required level of quality.
A nice and easy tool to use—just choose your percentage of compression
level, upload your image and view the result. Supported file types are GIF,
JPG, JPEG and PNG.
