Photo File Types and Free Photo Resizers
In an age of decreasing attention spans and the near-constant bombardment of colorful information, the digital visual image medium is taking over as the preferred means of communication. Whether its infographics, pictures, animations, or simple branding, getting your photos right is so important. But formatting images for the web can be a little more complicated when there’s so many different file types and formats out there.
The first step to identifying which photo format type to use is knowing how you intend to use your photo online. Depending on your intent, different photo file types may execute better than others. For instance, if you’re trying to display many different images while ensuring a smooth browsing experience, one photo type beats all the others: JPG.
The four most common photo file types you will encounter on the web are JPG, GIF, PNG, and SVG. Read along to get the ins and outs of each file type.
Resizing with JPGs
JPG is perhaps the original photo file type designed for the web. Released in 1986, JPG is still the most common photo file type in use owing to its minimal storage needs and speedy loading times. In addition to its minimal storage requirements, JPG is optimized for color, supporting millions of colors allowing you to transpose real-life imagery with little effort easily.
JPGs are lossy, meaning that they compress data and delete other unnecessary information when saved as such. This ensures that once converted to JPG, any image is web-ready. However, the downside is the reverse, trying to blow up JPGs or increase the image quality of a JPG found on the web can be difficult. In any case, JPG is the default web photo file format.
Unless your images need transparency, have embedded text requirements, or animations, then JPG is probably the best choice. But if you do require any of these additional perks, read on.
Photo Resizing With GIFs
While the debate on how to pronounce GIF rages on, this versatile photo file type is commonly used for animations. However, they weren’t always used this way. Released back in 1987, the GIF was intended to optimize the sending and receiving of digital imagery through slow internet connections. But with increasingly quick internet speeds, GIFs are now used mostly for animations and bringing images to life.
Resizing to GIF is pretty straightforward. They are lossless, the opposite of lossy, and do in fact retain all of the data contained in the original file. Since they can only handle 256 colors, they manage to remain reasonably small files even after resizing.
PNGs, like GIFs but better
Depending on your purpose, PNG’s are more versatile. Able to handle animation but with up to 16 million colors, PNG’s are a natural choice for more complex and demanding images. Similar to GIF, PNG is lossless meaning that all data is retained during compression or after using an online photo resizer. Finally, PNG is the only raster image file able to handle transparency. Of course, the downside with PNG is the large file sizes.
SVG’s, the end of pixels?
SVG’s are the latest photo file type to take the web by storm. Release in 2001, SVG has done away with the pixel in its entirety, offering its own unique take on image presentation through mathematically designed color schemes. Instead of blocky shapes, SVG presents beautiful curves that present more realistically than the competition. Able to handle any sort of manipulation, whether it be animation, transparency or something else, the only downside to SVG is the large file sizes.
