Optimize and compress SVG files online
Use this SVG optimizer to compress SVG files, minify SVG code, and reduce unnecessary markup in your browser without uploading by default.
Simple local workflow
How local optimization works
Add files, review the local queue, and process each file with the matching browser-based workflow.
Add SVG files
Select icons, logos, interface vectors, or exported SVG assets from your device.
Minify SVG markup
The browser applies a conservative SVGO pass to minify SVG code and remove redundant markup and metadata.
Download optimized SVG copies
Review size changes, keep your original files, and download each optimized SVG result separately.
SVG optimizer workflow
The upload area accepts SVG files only, so the page stays focused on vector markup optimization.
Browser-local SVG compression
Selected SVG files are read, compressed, and optimized in your browser instead of being uploaded to CompressWise servers.
Conservative SVGO online pass
The default optimizer keeps viewBox data, title and description nodes, and IDs to reduce the chance of breaking reusable assets.
Built for practical asset work
Why choose this browser-based tool?
A useful image workflow should be clear about privacy, quality, supported formats, and the tradeoffs behind every result.
Compress SVG file size
Use this SVG compressor when icons, logos, or exported vector artwork need smaller markup for websites and apps.
Minify SVG code carefully
The optimizer removes redundant SVG data while avoiding aggressive ID cleanup that can break masks, gradients, symbols, CSS, or scripts.
Private SVG optimizer online
The public optimizer is designed around browser-local processing, with no account or cloud history required for SVG optimization.
Batch-ready SVG workflow
Queue several SVG files, compare original and optimized sizes, and download each completed result separately.
Format and workflow
Choose the right optimization strategy
File type, transparency, markup, and visual detail all affect the best local processing route. Start with the page default, then review the result before publishing important assets.
Minify SVG icons for UI work
Optimize SVG icons before adding them to a website, design system, or app asset folder.
Compress SVG logo files
Reduce redundant SVG markup in logos while keeping the output easy to review before publishing.
Optimize exported SVG artwork
Designer-exported SVG illustrations can contain comments, editor metadata, and verbose paths that are worth cleaning.
Settings that match the job
Each public tool keeps the main workflow simple while still letting the format use the right local optimization behavior.
Preserve viewBox
Keep responsive SVG behavior intact
The current profile keeps viewBox data so optimized SVG files are less likely to lose responsive scaling behavior.
Keep IDs when they matter
Avoid aggressive ID cleanup
IDs can be used by masks, gradients, symbols, CSS, and scripts, so this SVG optimizer avoids risky ID cleanup by default.
Not a sanitizer
Do not treat optimization as a security filter
This tool reduces SVG markup. It is not a security sanitizer for untrusted SVG files.
Common use cases
Prepare lighter image assets for everyday work
A browser-based queue is useful whenever an image asset needs to travel faster, load sooner, or fit within a practical file-size limit.
Website icons
Minify SVG icons before committing them to a frontend project, design system, or documentation site.
Logo assets
Compress SVG logo files for web use while keeping the original design files unchanged.
Design exports
Clean exported SVGs from design tools before sharing them with developers or adding them to a repo.
UI libraries
Prepare vector assets for reusable component libraries and app interfaces.
Documentation
Reduce SVG file size before placing diagrams into docs, guides, and technical pages.
Static sites
Make inline or linked SVG assets lighter before deploying static pages.
Privacy by design
Your files should stay yours
The free public tool is designed around a local processing path. That boundary should remain visible as the product grows.
No upload by default
Selecting an SVG file should not send it to our server. The public optimizer is designed around browser-local processing.
No account required
You can optimize SVG files without creating an account, adding billing details, or saving a cloud history.
Keep original SVG files
SVG optimization creates a new copy. Keep originals when exact markup, comments, IDs, or editor data may be needed later.
Current release boundaries
Know the limits before you start
Clear limits make browser-local tools more predictable, especially on mobile devices with less available memory.
- This page accepts SVG files only. It is not for raster JPEG, PNG, or WebP image compression.
- A local batch can contain up to 10 SVG files to keep the browser workflow predictable.
- Each SVG file must be 5 MB or smaller in the current public interface.
- The default SVGO profile keeps viewBox data, title and description nodes, and IDs.
- The tool can minify SVG code, but SVG optimization is not a security sanitizer for untrusted SVG files.
- Very complex SVG files may take longer and depend on your device's available memory.
- Keep original SVG files when exact markup, comments, IDs, editor metadata, or archival copies matter.
Questions, answered
Browser-based tool FAQ
What does an SVG optimizer do?
An SVG optimizer reduces unnecessary vector markup, comments, metadata, and formatting so the SVG file can be smaller for web use.
Can I compress SVG files online?
Yes. Add SVG files to the browser-based tool, let the conservative SVGO workflow compress the markup, and download optimized copies.
Is this the same as an SVG minifier?
It overlaps with SVG minification. The tool removes redundant data and minifies SVG code while keeping important structure such as viewBox and IDs.
Are my SVG files uploaded?
No. The public SVG optimizer is designed to read and optimize selected files locally in your browser by default.
Does this SVG optimizer preserve viewBox?
Yes. The default workflow is configured to keep viewBox data so responsive SVG behavior is less likely to break.
Will it remove IDs from my SVG?
The current profile avoids aggressive ID cleanup because IDs can be used by masks, gradients, symbols, CSS, and scripts.
Is SVG optimization the same as sanitizing SVG?
No. This tool reduces SVG markup. Do not use it as a security sanitizer for SVG files from untrusted sources.
Why did my SVG not get much smaller?
Some SVG files are already compact, and conservative optimization keeps important structure. In that case, there may be limited room to reduce SVG file size.
