How to automatically and professionally remove photo backgrounds

Mar 26, 2015 by Nadav Soferman

RTB add-on It is common for e-commerce, media, and news sites to remove image backgrounds or make them transparent in order to place the main element of the image on either white or color backgrounds. The final result better integrates an image into a site or specific page’s graphic design. For example, a fashion site that presents clothes or shoes should have the main element of a photo (e.g. shoes) extracted from the original image background, then edited to fit the site’s catalogue design and structure.

Transform your image overlays with on-the-fly manipulation

Mar 19, 2015 by Nadav Soferman

Layer apply Front end developers may want to combine multiple images into a single image. For example, when creating and adding watermarks to stock photos, adding shapes or badges, preparing content for print (e.g. placing a logo on a t-shirt or a mug), adding a caption, and so on.

Multiple images can be combined by overlaying them one on top of the other. However, since it is not a given that both the underlying and overlaying images match each other, let alone your graphic design, you may need to perform further manipulations (e.g. resize, crop, change colors, create a better fit). This is where Cloudinary comes in.

How to dynamically create SEO friendly URLs for your site's images

Mar 11, 2015 by Nadav Soferman

SEO friendly image URLs Image URLs tend to appear as a long list of random characters that are not intended for viewers and are not very useful to search engines. Concise and meaningful image file names are better for search engines to extract information about an image, therefore supporting your site's SEO ranking.

Often times, users' uploaded image files do not have descriptive names. This creates a great challenge for developers and site content managers who need to maintain SEO friendly, short, and meaningful URLs. Cloudinary helped tackle this issue by offering users two new features: Root Path URL and Dynamic SEO suffixes. These features can be useful for website as well as web application owners, and are especially recommended for content-heavy sites, like online magazines and news sites.

How-to automatically identify similar images using pHash

Feb 19, 2015 by Nadav Soferman

pHash for image similarity detection Photos today can be easily edited by means of resizing, cropping, adjusting the contrast, or changing an image’s format. As a result, new images are created that are similar to the original ones. Websites, web applications and mobile apps that allow user generated content uploads can benefit from identifying similar images.

If your site allows users to upload images, they can also upload various processed or manipulated versions of the same image. As described above, while the versions are not exactly identical, they are quite similar.

JPEG-XR conversion with auto browser detection, optimize images for IE users

JPEG-XR Post Sites and apps are including more and more high-quality images. The more you can compress images to reduce their size in bytes, the smaller your bandwidth, the faster your site will load and the happier your users will be. But when compressing images, you need to make sure you maintain high visual quality.

Most web sites and mobile apps use the popular JPEG format to display their images and user uploaded photos. The JPEG format has efficient built-in compression that reduces image size while maintaining a reasonable visual quality. But you can reach much better results using more modern image file formats.

Reduce size of animated GIFs, automatically convert to WebM and MP4

Animated GIF to WebM and MP4

Short animated GIF-based video sequences seem to be spreading like wildfire around the web.

Media and news sites display short video segments, social apps allow their users to share animated GIFs with their friends, and while the dated animated GIF format is very useful for this purpose, it has one significant disadvantage - its huge file size.

Animated GIFs are not optimized for captured videos, resulting in large files, heavy bandwidth utilization, slow loading times, and sub-optimal user experience. Also, resizing and manipulating animated GIFs to match the graphic design of your site or app might be a lengthy, cpu-intensive process, as it consists of dozens or even hundreds of frames being manipulated individually.

How to automatically adapt website images to Retina and HiDPI devices

Jul 24, 2014 by Nadav Soferman

DPR Post Web development was much simpler only a few years ago, when we were building HTML pages that included images and photos, and all elements shared the same resolution units. If for example, you aimed at a standard 1024x768 screen, you knew these were exactly the number of pixels available for displaying HTML elements and images.

In 2010, Apple introduced the iPhone 4 with Retina display. In order to simplify things for developers, the logical screen resolution remained the same as previous iPhone models (640x960) while the physical screen resolution was exactly doubled (1280x1920). This means that if, for example, you embed an image tag in your HTML page with width of 200 pixels and height of 300 pixels, and you display a double-size image of 400x600 pixels, the Retina display shows all pixels of the larger image, resulting in a much clearer visual result and without performing browser-side down-scaling.
