SVG to PNG, privately

Drop in SVG drawings and download a PNG of each one, drawn by your browser at the size the file declares — or at twice, three times or four times it. Transparency is kept. The conversion runs entirely inside your browser — nothing is uploaded, the network meter below proves it live, and it keeps working with your wifi switched off.

Statusidle Files— OutputPNG Network since file read—

A picture of the drawing, not vector shapes, at the scale you pick (1× by default); the row prints the pixels, and says when the scale was reduced to fit the pixel limit or a source was animated (first frame only). A file that reaches outside itself is refused by name, naming the reference; so are a script, a <foreignObject>, a compressed SVG and one with no size. Fonts are the device's. Alpha is kept. Takes .svg.

How this converter works

An SVG is a description of a drawing and a PNG is a grid of pixels, so the conversion is a rendering rather than a translation. This page reads your file as text, takes the size the root element declares — width and height in any of the units the format allows, or the viewBox when those are absent — and writes that size back onto a copy as explicit pixel dimensions, because a browser asked to guess the size of an unsized SVG answers 300 × 150 and this page never lets that guess reach the output. The copy is handed to your browser's own SVG renderer as an in-memory image and drawn onto a canvas at the multiple you chose; drawing the image at its destination size re-renders the shapes at that size rather than stretching a small bitmap, which is why 4× is crisp rather than blurred. The canvas is then encoded to PNG with its alpha channel intact, and the row prints the exact pixel size that came out. Nothing in that path touches the network: the file is already on your machine and this site has no server to send it to.

The best evidence for that is not our instrument but your browser's. Press F12, open the Network tab, leave it visible, and run a conversion. Nothing gets added to the list. That panel is written by the people who make your browser, it records what a page actually does rather than what a page claims, and no code of ours can quiet it. This converter has one refusal that exists to keep that panel honest: an SVG loaded as an image is not allowed to fetch, so a file that references an image, a font or a stylesheet outside itself — at a web address or on a file path — renders with a grey placeholder, a blank, or a substituted font and makes no request at all, which means the meter would read zero on a drawing that came out incomplete. Files like that are refused before anything is drawn, with the reference named on the row, and a file containing a script is refused the same way because nothing from your file is ever run. A file that embeds HTML in a foreignObject is refused for a different reason: the browser will not let this page read the pixels back from one. Compare notes with the methodology page, which sets out two further ways to catch us.

The honest limits: the PNG is a picture of your drawing, not the drawing. Shapes and text become pixels at the multiple you chose, so the output has one fixed size and does not scale further without softening — keep the SVG for anything that has to be re-rendered later, and use SVG to PDF when you want a page rather than an image. Text is drawn with the fonts installed on this device, so a font the file names but does not carry is substituted silently, the substitute is what ends up in the PNG, and the same file can therefore come out differently on someone else's machine. Scripts inside an SVG never run, and an animated one is drawn at time zero, so a SMIL animation keeps only its first frame and the row says so — measured, a rect animating from red to blue came out red. A compressed .svgz is refused as what it is rather than decompressed, as is a file with no width, height or viewBox, because there is no honest size to give it. A browser canvas has a pixel limit — 268,435,456 pixels and 32,767 to a side is what this page allows, measured in Chrome, which hands back nothing at all past its own limit rather than an error — so a large drawing at a high multiple is rendered at the largest scale that fits, with the row saying which, and one that does not fit at 1× is refused rather than saved blank. Transparency survives: the PNG carries an alpha channel, which is the one thing SVG to JPG cannot do.

Frequently asked questions

Is my SVG uploaded anywhere?
No. The file is read as text by this page, drawn by your browser's own SVG renderer inside this tab, and encoded to PNG here. The network meter above counts requests made after your file is read and it stays at zero — disconnect entirely and convert again if you want to see that for yourself.
What size will the PNG be?
The size the SVG declares, at 96 pixels per inch, multiplied by the scale you pick. A file with width and height in mm, cm, in, pt or pc is converted at that rate — a 210 × 297 mm drawing is 794 × 1123 pixels at 1× — and one sized in pixels or plain numbers is read as CSS pixels, so a 200 × 100 file gives a 200 × 100 PNG at 1× and an 800 × 400 one at 4×. A file with only a viewBox is sized from the viewBox, one user unit per pixel, and the row says that is what happened. Every row prints the pixel size that actually came out, so you never have to work it out.
Is transparency kept?
Yes. PNG carries an alpha channel and this page writes one, so a drawing with transparent or semi-transparent regions keeps them and no background colour is invented underneath. That is the difference between this page and SVG to JPG, where the format has no alpha at all and transparency has to be flattened onto white before the file is written.
Why does my text look different?
Because text in an SVG is drawn with the fonts installed on the device rendering it, and an SVG loaded as an image cannot fetch a font it does not carry. If your file names a font this machine does not have, the browser substitutes another one without saying so and the substitute is what lands in the PNG — measured, a file naming a font that does not exist rendered identically to one naming no font at all. The same file can therefore come out differently on a different computer. Convert text to paths in your drawing program first if the shapes have to be exact.
Why was my file refused?
Because it needed something this page will not do. An SVG that references anything outside itself — an image, font or stylesheet at a web address, on a relative or absolute path, or in another file, an @import in its stylesheet — is refused by name, because a browser rendering it as an image fetches none of those and paints a grey box, or nothing at all, where the picture should be, so the meter would read zero on a page that quietly came out incomplete. A link wrapped around a shape is not a reference of that kind and is left alone. A file containing a script element is refused for the same reason: nothing from your file is run. A file with a foreignObject element — HTML embedded in the SVG, which is how draw.io and diagrams.net exports carry their text labels — is refused because the browser will not let this page read the pixels back from one; export the labels as paths or plain SVG text first. A compressed SVG, gzip bytes under an .svg name, is refused rather than decompressed. A file with no width, height or viewBox is refused because it has no size, and one that is not well-formed XML because the browser cannot draw it.
