The image in SVG format appears pixelated across various web browsers

My website is using an SVG image, but I've noticed that the image appears blurry on all browsers. Can anyone provide some insights into why this might be happening?

Here is the HTML code snippet:

<div class="panel">
   <img id="logo" src="img/teste.svg" alt="">
</div>

(The panel class is from Foundation)

Here is the CSS code snippet:

#logo {
position: absolute;
top: 0%;
height: 100%;
left: 1%;
width: 17%;
min-width: 219px;
min-height: 67px;
z-index: 1;}

I am unable to display the actual image, but here is the beginning of the SVG file:

<svg version="1.1" id="Layer_1" xmlns:x="&ns_extend;" xmlns:i="&ns_ai;" xmlns:graph="&ns_graphs;"
 xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="722.964px"
 height="239.988px" viewBox="0 0 722.964 239.988" enable-background="new 0 0 722.964 239.988" xml:space="preserve">

Answer №1

There may be an issue with the scaling of the element that contains the image.

It's possible that blurry svg css backgrounds are a result of using vw (viewport width) to set the size of the element. The browser may initially assume an absolute value and then adjust it based on the relative value provided (such as % or vw).

To address this, try the following:

  • Increase the width and height values: width: 7.2vw; becomes width: 14.4vw;
  • Add transform: scale(0.5);

By doubling the initial size and then scaling it down by half, you can achieve a sharper image after the browser renders the svg at a higher resolution.

Answer №2

<svg version="1.1" id="Layer_1" xmlns:x="&ns_extend;" xmlns:i="&ns_ai;" xmlns:graph="&ns_graphs;"
 xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="722.964px"
 height="239.988px" viewBox="0 0 722.964 239.988" enable-background="new 0 0 722.964 239.988" xml:space="preserve">

Ensure your height and width values are rounded to the nearest full pixel, such as 240px for height. This will help avoid browser rendering issues caused by fractional pixel values.

Answer №3

Ensure to include preserveAspectRatio="none" in the svg tag for proper rendering

<svg version="1.1" id="Layer_1" xmlns:x="&ns_extend;" xmlns:i="&ns_ai;" xmlns:graph="&ns_graphs;"
 xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="722.964px"
 height="239.988px" viewBox="0 0 722.964 239.988" preserveAspectRatio="none" enable-background="new 0 0 722.964 239.988" xml:space="preserve">
