SVG files contain vector graphics that scale perfectly to any size without losing accuracy.
Common Uses
Creating scalable logos and icons

SVG Optimization FAQ
What is an SVG file?
+
SVG (Scalable Vector Graphics) is an XML-based vector image format for two-dimensional graphics.
What actually changes when I convert SVG to a pixel format?
+
Resolution stops being free. An SVG stores shapes as mathematical paths, so it renders sharp at any size from a favicon to a billboard. Exporting to pixels freezes it at one chosen size — larger than you need is wasteful, smaller is unrecoverable. Decide the output dimensions before converting, and keep the SVG as the master you re-export from. SVG renders perfectly at any size, stays editable, is searchable and diffable as plain text, and is usually a fraction of the size of an equivalent PNG.
What happens to the text in an SVG when it becomes pixels?
+
It stops being text. In the original the letters are characters in a named font — selectable, searchable, still editable; after rasterising they are shapes made of pixels like everything else. That matters twice: the exported image cannot be searched or corrected, and it will render with a substituted font if the machine doing the conversion lacks the original. Convert the type to outlines first when the typography has to be exact.
Why do professional tools hand back SVG?
+
Because it is built to be worked on rather than distributed. The format keeps quality and structure through repeated opens, edits and re-saves, which is what a production pipeline needs and what a delivery format explicitly trades away. The consequence is size: keep SVG as the master and convert a copy for anyone who only needs to look at it.
Does SVG keep a transparent background?
+
Yes — the format stores a real alpha channel, so cut-out logos, product shots and overlays keep their transparency instead of arriving on a white rectangle. Converting to a format without alpha is where it goes wrong: the transparent areas are filled with a solid colour, usually white or black, and there is no way back short of masking the subject again.
Can I turn a photograph into SVG?
+
You can trace one, which is not the same thing. A vector file describes shapes, and a photograph is a field of noise with no shapes in it, so an automatic trace returns either a flat cartoon of the original or a file with tens of thousands of paths that is bigger and slower than the photograph was. Logos, icons and line art trace well. Photographs belong in a raster format and stay there. SVG cannot represent a photograph — tracing one produces either a crude approximation or a file larger than the original raster.
Can I use SVG directly on a web page?
+
Yes — every current browser renders it natively, so it needs no fallback copy and no conversion at publish time. The remaining question is weight rather than support: the same picture in a modern web format is frequently a third of the size at the same visible quality, which is worth doing on anything that appears above the fold.
Who controls the SVG format?
+
Nobody, and that is the point of it. The specification is public, anyone may implement it without asking or paying, and no company can change the terms later — which is why archives, standards bodies and public institutions specify formats like this one for anything that still has to open in twenty years. The trade is not compatibility, which is excellent; it is that there is no vendor to call when some tool implements the spec badly. SVG is the W3C’s XML-based vector format, a recommendation since 2001 and now native to every browser.
Can I just rename the extension instead of converting SVG?
+
Almost never, and it is worth understanding why: the extension is a label, while the bytes inside are structured for one specific format. Renaming produces a file whose name promises something its contents do not deliver, and whatever opens it either refuses the file or misreads it. The one narrow exception is two formats that are genuinely the same container under different names — and even then a proper rewrap is safer than a rename.
Can I convert a whole folder of SVG files in one go?
+
With an account, yes — drop them in together and they are queued as one job rather than handled one at a time, with the same settings applied across the batch and the results returned together. Free conversions run a single file at a time (merge tools take two); a paid plan is what unlocks batch processing and the larger per-file limit, which is what makes converting a whole archive practical.
What happens to my SVG file after the conversion?
+
It is deleted. The upload and the converted result both sit on the server only as long as the job needs them and are then removed automatically; the transfer runs over HTTPS in both directions. Nobody reads the contents, nothing is indexed, and nothing is passed to anyone else. If you would rather not wait for the automatic sweep, closing the job removes the files immediately.
How long does converting an SVG take?
+
Usually seconds. Small files are effectively instant, and the cases that take real time are the ones doing real work: a long recording that has to be re-encoded frame by frame, a scanned document going through character recognition, or a very large batch. Where a conversion only rewraps or repackages the existing data it stays fast no matter how big the file is, because nothing is being decoded.
