Optimise SVG files without pasting them into a website
SVG optimisers are usually a textarea on someone else's site. PixelDev does it on your machine, which matters when the markup is a client's logo or an unreleased icon set.
Why do it in PixelDev?
A fast, private desktop toolkit — not another website that uploads your files.
Markup stays on your PC
No pasting into a web form. The file is read from disk and written back locally.
Control the cleanup
Precision, hidden-element removal and transform conversion are adjustable rather than a single fixed preset.
One app, eight free tools
The optimiser sits beside a favicon generator, icon factory, colour extractor, colour picker, image inspector, placeholder generator and Base64 converter.
How to optimise svg offline
4 steps, entirely on your PC.
Download PixelDev free and install it on Windows.
Open the SVG Optimizer and select your file.
Adjust the cleanup options if the defaults are too aggressive.
Save the optimised file back to disk.
Frequently asked questions
Is the SVG optimiser free?
The optimiser is one of the eight free tools. The full optimiser with structural cleanup, plus the tree-based SVG viewer and editor for recolouring and editing, are part of the one-time $11.99 upgrade.
Will optimising break my SVG?
Aggressive settings can change how some files render, which is why precision, hidden-element removal and path merging are exposed as options. Keep the original until you have checked the result.
Can I edit the SVG as well as optimise it?
The visual SVG viewer and editor, with tree-based recolouring, is a premium tool. Optimisation is free.
Does it work without an internet connection?
Yes. PixelDev is fully offline after install.
What are the system requirements?
Windows 10 or 11, 64-bit.
