It should be noted, that in the current version of the app the optimization is implemented without any losses that is to say, that while compression the quality of the photo remains the same without any deteriorations.

This solution can be a cup of tea both for professional users and for the beginners. There are no needless buttons, icons, moves. The app has a rather intuitive, modern and minimalistic interface. PhotoBulk a quick way to optimize photo on Macĭespite being a non-professional solution this bulk photo editor copes with the task like a professional one. However, it can be rather misleading, as non-professional image optimizer apps can perfectly cope with the task, as for instance, PhotoBulk presented by Eltima Software. It is a widespread belief, that in order to prepare graphics for the web, you should use only editors focused on this because only then you can get the most optimized images that will not create an excessive load on your hosting server when they are loaded into users' browsers.

There are many compress image Mac solutions that know how to work with bitmap graphics. image optimization plays an important role in SEO.the loss of image quality if uploading the original one.the size of the image affects the speed of the downloading page.Make sure that the speckle in the image is minimal, as this will significantly reduce the size of the JPEG files.īesides that among the reasons for using file compressor apps one can highlight the following:.In such cases, the JPEG algorithm may, as a result, create larger and larger files with a constant compression rate. Avoid compressing the file several times, because compression defects can accumulate and lead to decreasing of image quality.Save an image using lossy compression only after editing is finished, since many image manipulations can multiply compression defects.Useful tips when using an image compressor

That is why to find a good image compressor software is a question of a great concern. The visible differences between compressed files and their source files are called “compression defects”. The final compressed file is no longer identical to the original. Lossy compression, in contrast, can create files that are much smaller but achieve this by selectively discarding image information.
Lossless compression ensures the safety of all information about the image, even if the final image size is somewhat larger.
File compression is usually suitable for small photos and is not suitable for professional drawings or high-quality illustrations, presentations.Ĭompressed files are much smaller than the uncompressed ones and are divided into two main categories: “lossy” and “lossless”. A compressed file will never be an exact copy of the original, with some exceptions. But with this almost always there is a loss in quality since the main compression algorithm is to select several pixels and replace them with one or two similar in shade. Because compression can very effectively minimize the size of the images just twice or several times. There are quite a few types of compression schemes, but the essence of their existence can be reduced to one task – to compress image to a specific size and we are talking about the bitmap file as efficiently as possible. However, we are more interested in bitmap formats as we often have to deal with them and namely why to optimize photo when uploading it to the Internet.īesides that, image file formats can be distinguished based on compression effects. Surely everyone came across them because many e-books and documents are stored in PDF-format. The most famous example of such a format is. Complex formats, as it appears from the name, have features of both vector and bitmap images. Vector images are based on geometric shapes – points, curves, circles, polygons. In general, image formats can be divided into 3 large groups – bitmap, vector, mixed or complex. There are countless image formats, and from time to time new ones also appear. Some formats are best suited for obtaining the optimal balance of quality and file size when storing your photos, while other types will make it easier for you to recover a damaged image. This article is aimed to shed light upon such topics as “How to compress image sizes” as well as “What is compression”.įirst of all, the understanding which image format to use will give you the opportunity to get the most out of it. However, everything is not so difficult as it may seem for the first time. Why to optimize photo? Or simply why to compress image to a specific size? What is compression and when you should use it? These difficult questions can scare a lot of the users.
