Use this free vector file resolution resizer in your browser. No sign-up, no download and no upload: everything runs on your own device, so your data stays private.
What this tool does
Vector files do not have a fixed resolution the way photos do, but journals and slide tools still ask for an exact pixel size. This tool rewrites the width and height of an SVG while keeping its aspect ratio, so the artwork scales cleanly instead of stretching. Paste the SVG, type the new width, and copy the resized code back out.
How to use it
- Paste or type your SVG code and new width in the box above.
- Adjust any settings, such as cutoffs, scales or styles, to match your data.
- Click the run button and read the output below the tool.
- Check the summary numbers before you copy anything into a document.
- Copy the output, code or image into your figure, slide or report.
Worked example
Paste the sample 200×100 rectangle and set the new width to 800. The tool returns an 800×400 SVG, exactly four times larger with the same proportions. Set 300 instead and you get 300×150, which is the right size for a half-page figure.
Tips for better results
If your SVG has no width or height, the tool reads them from the viewBox instead.
Honest limits
SVG only. EPS and PDF files cannot be resized in a browser tool like this; they need desktop software such as Inkscape or Illustrator, and the tool says so plainly rather than pretending otherwise.
Choosing the right settings
Start with the default values. They are chosen to show a sensible result at once, so you can see the layout before you touch your own data. Then change one setting at a time. Changing one thing at a time is the fastest way to learn what each control does, and it stops two changes from cancelling each other out. If the output looks wrong, check the input format first: a missing comma, a swapped column or a stray space causes most errors, and the tool reports what it received in its summary line.
Using the result in a figure
For a figure, keep the output simple. One message per figure, short labels, and a caption that states the method and the settings you used will serve readers better than a dense, decorated chart. If a journal or supervisor will see the result, note the tool name, the input values and any cutoff in your methods or caption, so the figure can be reproduced later. That habit also helps you: six months from now, the caption is the only record of how the figure was made.
Common questions
Do I need an account? No. The vector file resolution resizer runs entirely in your browser with no sign-up and no saved data.
Is my data uploaded anywhere? No. Your SVG code and new width stays on your device, which is why the tool is safe for unpublished work.
Can I use the output in a paper or presentation? Yes. The output is yours to reuse; just check it visually once, note the settings in your caption, and credit the method, not the tool, in your references.
What if the result looks wrong? Check the input format first, then change one setting at a time. Most errors come from a missing comma, a swapped column, or a value outside the expected range, and the summary line under the tool shows what it actually received.
Try the vector file resolution resizer above with the sample data, then with your own. It is free, it needs no account, and it works in any modern browser.
When you reuse the result, keep a short record of the inputs and settings you used. A one-line note in your project file, such as the data pasted, the cutoff chosen and the date, is enough to reproduce the figure later. If a collaborator questions a number, that note lets you rebuild the exact output in seconds instead of guessing what changed.
