1Drop your SVG files into the box above, or pick them from your device — there is nothing to install and no account to create.
2Choose how hard to squeeze: a quality or bitrate target, and optionally smaller dimensions if size matters more to you than detail.
3Start the job and let the workers re-pack the file; your original is never modified in place.
4Compare the new size against the original, then download the compressed SVG file.
Compress SVG FAQ
What do I get back, and can I control the trade-off?
+
A single compressed file per input, at a quality or bitrate level you choose rather than a fixed default. If the result is not small enough, changing the dimensions or the duration will do more than pushing the quality slider further down.
How does Compress SVG actually make the file smaller?
+
Concretely, nothing is re-encoded at all — editor metadata is stripped, redundant groups and empty transforms are collapsed and path coordinates are rounded to a sensible precision, so the file gets smaller while remaining pixel-perfect at every zoom level. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
Is there anything specific to SVG I should know before compressing?
+
Yes — nothing is sampled: the file is edited as text, so the result is still infinitely scalable and still diffable in version control. It is worth knowing before you overwrite an original you might need again.
What is the most common mistake when compressing SVG files?
+
Compressing the same file repeatedly. Each pass on a lossy format is a fresh generation of loss and the savings shrink while the damage accumulates. Go from the original to your target in one step, and keep the original.
What can I upload to Compress SVG?
+
SVG files, including ones exported from Illustrator, Figma, Inkscape or a charting library. Embedded raster images inside the SVG are carried through as-is.
Is there a file size limit on Compress SVG?
+
Yes: free accounts process images up to 25 MB each, which an SVG essentially never approaches — a complex illustration is usually a few hundred kilobytes of text. In practice the thing that makes an SVG heavy is thousands of path nodes from an auto-trace, not the file size, and that is a different problem from the cap.
Will Compress SVG lower the quality of my SVG files?
+
No, and it cannot: an SVG has no pixel grid to degrade. The geometry is transformed mathematically, so the result is still crisp at any zoom level and still openable in a vector editor.
Can I run Compress SVG on several SVG files at once?
+
Yes. SVGs are small and parse quickly, so a batch of icons or logos finishes almost as fast as a single file. Settings apply uniformly across the set.
Why does a EPUB site host Compress SVG?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Compress SVG runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Compress SVG is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Compress SVG means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Compress SVG here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
