1Upload the SVG files you want resized — work from the largest original you have rather than from a copy you already shrank once.
2Type a target width, a target height or a percentage, and leave the aspect-ratio lock on unless you deliberately want stretching.
3Run the resize; every file in the batch is taken to the same target in a single pass.
4Download the resized SVG file, or the whole set together as one archive.
Resize SVG FAQ
What dimensions should I actually target?
+
Match the slot it will live in. A full-width web hero rarely needs more than 1920 pixels wide, a content image 1200, a thumbnail 400, and doubling those numbers covers high-DPI screens. Anything beyond that is bytes nobody sees.
How does Resize SVG change the dimensions?
+
Concretely, there is no resampling at all — the viewBox and the geometry are rewritten, so the result is exactly as sharp at the new size as the original was at the old one. You give it a target width, a target height or a percentage, and it works from the original rather than from a previously resized copy.
Is there anything specific to SVG I should watch for?
+
Yes — nothing is sampled: the file is edited as text, so the result is still infinitely scalable and still diffable in version control. Worth checking before you resize a file you will not be able to regenerate.
What is the most common mistake when resizing SVG files?
+
Upscaling. Enlarging cannot invent detail that was never captured, so the result is a soft version of the original at a bigger size. Always resize down from the largest source you have, and resize once rather than in stages.
What can I upload to Resize 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 Resize 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 Resize 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 Resize 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 Resize 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. Resize 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 Resize 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 Resize SVG means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Resize 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.
