Why Use SVG Resize Online?
Change SVG Dimensions Precisely
Resize SVG online by entering an exact width and height in pixels, or scale by percentage. Numeric controls make it easy to match a design spec, a grid token, or the size of an exported PNG.
Aspect Ratio Lock
Keep the aspect ratio locked and proportions stay intact, so icons, logos, and illustrations never look stretched. Unlock it when a fixed box size matters more than the artwork filling it.
ViewBox-Aware Output
The viewBox is preserved and updated when needed so the resized SVG scales correctly in CSS and HTML. That avoids unexpected cropping, extra whitespace, and layout shifts.
Live Preview
Every change updates instantly with zoom and background options, so you can confirm padding and alignment before export. A contrasting background makes stray strokes obvious.
Flexible Export
Download the resized SVG or export a PNG in one step. Keep both formats together when you need a raster fallback for docs, slides, or chat tools.
Local, Private Processing
The resizer runs entirely in your browser, so SVG files never leave your device. Local processing keeps client assets private and avoids upload delays on large files.
How to Resize an SVG Online
1
Add Your SVG
Drag and drop a file or paste SVG markup. The resizer loads the source locally and keeps its original viewBox. If the SVG has no viewBox, add one before resizing.
2
Set Width and Height
Enter the target width and height, or keep the aspect ratio lock on and scale proportionally. The live preview shows exactly how the resized SVG will look.
3
Export Results
Download the resized SVG or export PNG instantly. Keep filenames consistent, for example icon-name-24.svg, so size variants stay easy to track.
SVG Resize Online FAQ
How do I resize an SVG online?
Drop your SVG into the editor above, enter the target width and height or scale by percentage, then download the result. Everything runs in your browser, so no upload or sign-up is needed.
Can I resize an SVG without losing quality?
Yes. SVG is vector art, so resizing only changes the coordinates and every path stays sharp at any size. The resizer never rasterizes your file, so there is no blur and no quality loss.
Can I resize an SVG while keeping the aspect ratio?
Yes. With the aspect ratio lock on, width and height stay proportional, so icons and logos are never stretched or padded. Unlock it only when a fixed box size matters more than the artwork filling it.
What happens to the SVG viewBox when resizing?
The viewBox is kept and updated when needed so the resized SVG scales correctly in CSS and HTML. That prevents unexpected cropping, padding, and layout shifts in production. If your source file has no viewBox, use Fix viewBox before resizing.
Can I set an exact SVG width and height in pixels?
Yes. Type exact pixel values for width and height to match a layout spec, a design token, or a component size. The preview updates as you type.
Can I resize an SVG by percentage?
Yes. Percentage scaling keeps the proportions and is the quickest way to produce 2x or 3x versions of an icon set for retina displays.
Can I export PNG after resizing?
Yes. Download the resized SVG or export a PNG for slides, docs, or platforms that do not support SVG.
Is this SVG resizer free?
Yes. SVG Resize Online is completely free, with no sign-up, no watermark, and no limit on how many files you resize.
Does SVGView upload my SVG files?
No. The resizer runs locally in your browser, so your files never leave your device. That keeps client assets confidential and lets you work offline.
What is the file size limit?
Files up to 10MB work comfortably. Very large or heavily filtered SVGs may take a moment to render; optimizing the file first usually speeds things up.
Related SVG Tools
Use SVG Resize with these tools to rotate, optimize, and export consistent assets.
SVG Rotate & Flip
Adjust orientation before SVG Resize so the final dimensions match your layout. This keeps width and height predictable after rotation.
Open toolSVG Optimizer
Compress the file after SVG Resize to keep output lightweight. Smaller files load faster in apps and design tools.
Open toolSVG Viewer
Preview the asset before and after SVG Resize to verify alignment. Use grid backgrounds to check padding.
Open toolSVG to PNG
Export PNGs alongside SVG Resize results when you need raster fallbacks. This is handy for presentations and docs.
