Frequently asked questions
Are my SVG files uploaded?
No. SVGO runs in your browser, and your files never leave your device.
What does the optimizer remove?
It uses SVGO's default preset: comments, metadata, editor data from tools like Illustrator, Inkscape and Sketch, hidden or empty elements, unused definitions and redundant attributes. It also shortens path data, colours and numbers. The viewBox is always kept, so the SVG still scales with CSS.
What do the settings do?
Multipass repeats the optimization until the file stops getting smaller. Pretty print adds line breaks and indentation so the code is readable, which makes the file slightly larger. Precision sets how many decimal places numbers keep. Remove width and height lets the SVG size itself from CSS.
Will the image look different?
Usually not. A precision of 1 or 2 can visibly shift detailed shapes, so compare the preview before you download. If something looks off, raise the precision.
Why is the title removed?
SVGO's default preset removes title elements, along with desc elements that are empty or only say which program created the file. If your SVG relies on its title for accessibility, add it back, or give the image alt text where you use it.
