Save more for you! Reduce the Size of PNGs. Online PNG compressors. Weights and measures of PNG Images The image file format PNG is a compression format originally used as a vector graphic format. It is often used for images of text, logos, icons, maps, and other illustrations. It is also widely used as an image format for games, 3D graphics, and other graphics, such as animation and games. Furthermore, it has several variations of the PNG file. These include the original PNG file format, version 0.8, the version 1.0, version 2.0, and version 3.2. The file size (1 KB for each bitmap) can vary from less than 1 KB for a very small picture to more than 50 KB for large pictures. To compress the image with PNG, you may compress the image itself using the following methods: TIFF compression The TIFF compression (the only compressed file, the original PNG is an uncompressed file) was created by Steve Bell in 1991. It has a unique property, TIFF can be displayed by the same software as the TIFF format used by it. The TIFF compression used by Apple's QuickTime and Photoshop. The DCT (delta-tensing) method DCT stands for delta-theta-conversion. As its name suggests, delta-tensing is a method of reducing noise which can significantly reduce the file size of a PNG image. There are several methods to convert between different formats for your file. However, not all applications have the ability to handle the different versions of the PNG file; in turn, this often makes them very buggy and slow. This article gives an overview of the different PNG compression methods for online compression: TIFF: delta-theta-conversion, compression and compression by weight The TIFF compression was first created by Steve Bell in 1991. The key principle of this format is delta-tensing — a method of reducing noise — which should result in a significant reduction in the file size of a TIFF image.

How do I reduce the KB of a photo?
There are a number of ways to reduce the filesize of a photo largely depending on the file and desired quality. Here are the main governing factors Image Resolution (that is in terms of pixels or dimensions often also called Image Size) Image Quality Compression File format JPEG is by far the most popular format for photos so Ill talk more about it below but before that let get some of the others out of the way. PNG TIFF PSD PNG (Portable Network Graphics) TIFF and PSD (Photoshop file) are file formats that support losslesspression. That is you canpress them without losing quality. However you will see limited gainspared to lossypression formats. The simplest way to reduce the file size for these is to reduce the resolution italic or the number of pixels. So if your manipulation tools such as Photoshop and ImageMagick. For PNG files you can use a tool such as pngquant - lossy PNGpressor s to reduce the size which removes some data without any noticeable difference. JPEG JPEG has its limitations such as lack of support for transparency though it is much more versatile in other ways. It is a lossy format so increasingpression can permanently reduce some of the quality. Recent versions however allow you to reduce the file size withoutpromising on quality. As with the other formats reducing the resolution is the easiest way to reduce the file size. This can be achieved with the aforementioned such as when where or how it was created) to get smaller photos. The tool I like to use for this is Optimize JPEG - Resize and reduce photos s . It allows you to set the desired quality and size (in terms of pixels) as well as choose to remove or keep the metadata. You can thenpare both the s. WebP support was previously limited but almost every popular browser now supports it. Unlike JPEG it can even do transparency.
How can I create an avi file from a series of .png files from the UNIX terminal?
You can use MEncoder MEncoder is capable of creating movies from one or more JPEG PNG TGA or other (s) with libjpeg (when decoding PNGs it will use libpng).n Examples.

Super Mario Bros. game was just 31 Kilobytes. How's that possible?
This is a fascinating question. I read its answer a couple of months ago THE EXACT EXPLANATORY ANSWER . Without wasting any time let me share it with you. I want to set something clear here though were not reallyparing Apples-to-Apples so let define some technologies first. How Mario Works So let talk about how the original Super Mario game worked from an asset perspective. The original NES console was only designed to output that needed to be displayed to the screen was 18kb in size. Besides that the NES only had 2kb of RAM. A cartridge itself could could hold 8k to 1mb of game data. So there was no way to fit the entire game contents into main memory. Basically a subset of the 1MB cartridge data must be loaded into the 2kb RAM and used to render the 18kb screen. How does one achieve that? SpriteSheets s%2puter_graphics%29 . Sprite sheets contain small tiles of graphics that are re-used over and over again. For example below is a remake of the original super mario sprite sheet It not the exact original sprite sheet but you can get a sense of the small blocks of data that can be use over-and-over again. Each small 16x16 pixel square represents a tile and artists would string these together to create the actual levels. The levels themselves just became a giant 2D array of indexes into the sprite sheet. (I talk about this in a lot more detail in Lesson 3 of my HTML5 Game Development course @ Udacity s or in my book HTML5 Game Development Insights .) Tack on some Run-Length-Encoding s or some basic LZ77 s and you get a fairlypact format for levels. Behold that level that you parents could neverplete. So with concepts like tile-sheets and sprite-sheets we can use a small set of pression. How Images arepressed Here the not fair italic part of thisparison. Generic ; Besides some color quantization there no real logic added to determine if another 16x16 block could be an exact duplicate italic of the current one. This generally means there a lower-bound on how a given block of data ispressed. For example JPG s breaks a given s 325 474 A much betterparison. The . kkrieger s demo fit 3 minutes of a 3D shooter gameplay with physics sound ures and AI into 64kb of data. Seems like a massive amount of gain for just 24kb more than the original Mario. It just goes to show with the right amount of foreknowledge about your data you can do great things withpression. Source Where do all the bytese from?

Every computer file is made up of binary digits, and is a number. Why can't we just divide that number by 2 (or even something larger like 10) to get a smaller number, which will take less space (bits) to store?
The question is Everyputer file is made up of binary digits and is a number. Why can't we just divide that number by 2 (or even something larger like 1) to get a smaller number which will take less space (bits) to store? italic The question starts with the wrong premise. Computers rarely work with binary. Most of the instructions and operations aputer performs work on are in powers of base-256 (8 bits). Unfortunately pedagogy and popular culture are stuck on the binary term which has been over applied. Yes there are situations where binary is appropriate - but theyre rare. And yes you can offer a simplified explanation that everything is ultimately based on binary mathematics and representations. But it rare that knowing how a twosplement binary representation of a number appears when represented as a unsigned binary representation is really dealing with a pathological condition. The smallest addressable unit of memory (for most CPU instructions) is an 8 bit quantity capable of representing 256 distinct symbols. Some instructions even allow an implicit ordering too such that one symbol is greater (in aparison) than another. Most CPU also offer 16-bit units (with similar numericparisons) for base-65536 32 bit representations for base-4294967296 and perhaps even larger. (And floating point representations areplicated synthetic representations much like base-1 exponential notation with a sign exponent and mantissa.) Computer files are usually held (eventually) on some kind of storage that retains the values even after electrical power is removed. That kind of storage is in terms of blocks - often a power of two multiple - like 512 or 496 or 16384. The representation of a file as a stream of 8-bit octets is done by imposing a structure based on that underlying block unit for a particular filesystem. horizontal-rule In short my diatribe is that exingputer information handling in terms of binary data is as helpful as exing biology in terms of quantum physics and ignoring basic chemistry (much less organic chemistry.) horizontal-rule To use a different metaphor aputer file can be considered like a pad of paper. There an order to the pad (first page second page etc.) But the contents expressed on the paper can be simple or an enhanced sort of (with letters or underlining) or a form to fill out or a picture etc. Some of the data can be represented in ways that can bepressed to fit more information in the same space. One form ofpression (of ) is to use variable-length symbols where the mostmon symbols (letters) are the shortest and the leastmon are the longest. Morse Code does this. The letter E is the shortest code in Morse. Another way is to name an object instead of describing it. 5 inch radius circle takes up a LOT less space than a drawing of a 5 inch radius circle. horizontal-rule If all you care about are the 26 letters of the Latin alphabet and 1 arabic numerals you have only 36 symbols to distinguish. But if your includes lower case and capital letters as well as punctuation and other graphic symbols then things be moreplicated. If you want to represent other alphabets or systems of writing - things be VERYplicated and won be representable by a base-256 symbol set. If the symbols span multiple languages then using variable length encoding might not even produce an optimalpression for any one language. horizontal-rule But that even more fuel for my binary terrible pedagogy diatribe.
