With so many characters, non-standard shapes offer the greatest opportunity for optimization. The entire value is about twenty times longer. Here’s the kiwi’s path-the first bit, and the last value: To describe anything other than basic shapes, the path tag is required.
#Make visuals great again 2.6 code#
Here’s what the code of our example’s ellipse looks like: Since these shapes are well-defined, the amount of code needed to describe them is minimal-all you need are some attribute/value pairs. Visual representation of the Kiwi bird SVG from Chris Coyier’s Using SVG.īasic shapes have their own tags: circle, ellipse, line, polygon, polyline, and rect. Its dimensions are 100px width by 82px height, viewBox is 0 0 100 82, and decimal precision is seven-the highest Illustrator allows. Our example is based on the kiwi bird from Chris Coyier’s Using SVG and has two paths: one is an ellipse, the other is a kiwi. Next, we’ll examine paths-what defines the drawing-and how dimension, viewBox, and decimal precision affect the number of characters they contain. That’s where adjusting dimensions and viewBox come into play. What isn’t addressed by this setting is how many significant digits we have to the left of the decimal point. Our goal is to balance file size and visual fidelity and know precisely where that balance is perfect. As precision increases, more detail is present, but beyond a certain point, may not increase fidelity-wasting bytes. As decimal precision is reduced, so are the amount of bytes-potentially seven less bytes per number.īut as precision decreases, SVGs can visually break because there may not be enough numeric data to accurately describe them. Remember, characters equal bytes and the less we have, the smaller the file will be. It defines the number of digits after the decimal point for all numeric values. When you save an SVG, you’ll need to indicate a decimal precision-usually an integer between one and eight.

But more importantly, as we shall see, this method has a much greater impact saving bytes in paths. And now that you know, you’ll set up your files this way from the start-this should be built-in to your file setup.

Even though the savings are small, this optimization is easy to do and has no negative effects. Finally, scale the artboard down to reduce the number of digits: viewBox="0, 0, 252, 252"Īdding another two for an overall savings of 42 bytes. Next, round width and height to whole numbers-scaling artwork if needed: viewBox="0, 0, 2872, 468" This saves 23 bytes since one character equals one byte. This is much too long considering we can perform a micro optimization in a lossless way-without changing the image visually. 2) viewBox and micro optimizationĭimensions, in addition to guiding path articulation, also determine the viewBox attribute’s values.Ī viewBox could look like this: viewBox="-351.7474061, 2051.85204372, 2520.3925946, 2520.13473217" By setting the dimensions, you’ve already partially determined what the file size will be. The code representation is derived, in part, from the container’s dimension (or “artboard” in Illustrator) which is described by discrete measures. While that’s true of the visual representation, the same is not true of the code representation-that remains constant. This may not seem critical since, by definition, vector graphics are scalable and visual dimension will vary depending on its context. Part of the document setup is defining physical dimensions. To create an SVG, fire up your favorite vector graphics editor, setup the document, and make something visually engaging.

By understanding how each impacts the articulation of vector paths, you can discover how to adjust them to achieve the optimal optimization.ġ) Physical dimension: debunking the “Scalable” in SVG (sort of) Each SVG has a specific combination of these three properties that will yield the smallest possible file size. Arbitrarily setting any one of them can cost you valuable bytes-even kilobytes. Three factors determine the optimized file size of an SVG: physical dimension, viewBox, and decimal precision. Alter that system, get different results. For instance, decimal precision is a big factor in SVG optimization, but it’s a rather arbitrary metric depending on the coordinate system of SVG.

There are several great tools for that, but as Raymond is about to show you, the best results come from a deeper understanding and a little manual work. Like it’s raster brethren, SVG should be optimized before being used on production sites.
