Convert SVG to JPG - And When You Actually Should

This tool converts SVG to JPG at whatever size you ask for, entirely on your own device. It also tells you something most converters will not: for vector artwork, JPEG is usually the wrong choice. JPEG was built for photographs, and the compression that makes photographs small does measurable damage to the flat colour and hard edges that vector drawings are made of. It also has no transparency channel at all, so every empty area becomes a solid colour whether you want one or not. There are real situations where you need a JPG anyway, because some upload forms and email tools accept nothing else, and this page exists for those. Everything below is measured through this converter rather than quoted from a specification, including how far JPEG actually pushes a flat white background off white, so you can decide with evidence instead of folklore. If the destination will take PNG or WebP, both are better here, and both are one click away.

How to use this tool

  1. Drop in your SVG

    Drag an SVG onto the box above or click to browse, up to 5 MB, several at once. The file is checked by its contents rather than its name, so a mislabelled file is refused instead of being half-rendered.

  2. Set the output size

    Scale multiplies the source size by 1×, 2×, 4× or any figure you type. Exact size takes a pixel width with an aspect-ratio lock. The drawing is redrawn from the vector at that size, so a larger number means more real detail rather than a stretched copy.

  3. Pick the background colour

    JPEG has no alpha channel, so this is not optional - something has to sit behind the artwork. White is the default because it matches most documents and upload forms. Choose the colour your artwork was designed to sit on, not a guess, because the wrong one shows as a hard rectangle.

  4. Choose a quality

    The slider runs from 10 to 100 and defaults to 90. On vector artwork the difference is dramatic: our gradient test file came out at 9,173 bytes at quality 90, 2,897 at 50 and 1,779 at 20. Below about 80, edges visibly break up into blocks.

  5. Convert and download

    Click Convert to JPG. Files are processed one at a time with a progress bar each. Download them individually, or take everything as one ZIP when you have converted more than one.

Frequently Asked Questions

Why does my logo have a faint grey halo in the JPG?

That is JPEG ringing, and we measured it. Converting the Lucide download icon at 512 × 512 and quality 90, 648 pixels that were pure white in the lossless version drifted by up to 30 levels. On a denser pixel-art mark, 2,394 pixels drifted by up to 50 levels - enough to see as a smudge around every edge.

Does JPEG damage flat colour more than WebP does?

It damages it harder, though less widely. At the same quality 90 on the same icon, WebP disturbed more background pixels - 2,090 against JPEG's 648 - but its worst deviation was 14 levels against JPEG's 30. Scattered faint noise reads as clean; a concentrated halo along every edge does not.

Can I keep the transparent background?

No, and no tool can. JPEG has no alpha channel, so transparency cannot be stored in the format at all. Every area your SVG leaves unpainted becomes the background colour you pick above. If you need transparency, use PNG or WebP instead - both keep it exactly.

Does the background colour change the file size?

Yes, and it changes the artefacts too. A flat backdrop compresses to almost nothing, so the size is driven by the artwork. More usefully, ringing scales with contrast: a mid-tone background close to your artwork's own colours produces a visibly softer halo than stark white behind a black logo.

Is the JPG smaller than the PNG?

Usually yes, and usually beaten by WebP. At 512 × 512 on a white background at quality 90, our icon came out at 24.4 KB as PNG, 11.4 KB as JPG and 4.1 KB as WebP. The pixel-art mark measured 44.7 KB, 26.7 KB and 8.6 KB. JPEG wins against PNG and loses to WebP every time.

When is JPG genuinely the right answer?

When the destination refuses anything else. Older email clients and newsletter builders still choke on PNG transparency, some print and photo-lab portals accept only JPEG, and a number of marketplace and job-application upload forms reject every other format. Compatibility, not quality, is the reason to be on this page.

What quality should I choose?

Stay at 90 or above for anything with text or hard edges. Vector artwork punishes low settings far more than photographs do, because the compression works by discarding sharp transitions and a drawing is mostly sharp transitions. Below 80 the edges break into visible blocks well before the file gets usefully small.

Can this produce a CMYK JPG for print?

No. The output is RGB, because browsers render and encode in RGB and there is no colour-managed CMYK path in the browser. A commercial printer will convert it, but the shift is theirs to control, not yours. For print work, hand over the original SVG or a PDF and let the print shop do the separation.

Are my files uploaded to a server?

No. Everything runs in your browser, using the same engine that draws SVGs on any web page. Nothing is sent anywhere, nothing is stored, and nothing is queued behind other people's jobs. The only limit on speed is your own device.
