What the artifacts look like
Small checkerboard blocks in flat areas, coloured fringes along text and a slight shimmer around outlines. On screen you barely notice them; on a traced SVG they show up as extra tiny paths.

Why JPEGs need a little extra care
JPEG is a lossy format: it saves space by approximating pixels, and it leaves faint blocks and halos around hard edges. A tracer sees all of that as real detail.
The fix is one switch
Turn on Reduce noise before converting. It smooths the JPEG grain so the tracer follows the real shapes, not the compression pattern. Save without it for crisp icon-like artwork.
Small JPGs benefit from upscaling
Old web graphics are often 400 px wide. Upscale 2× or 3× gives the tracer a larger canvas, and curves come out rounder instead of stepped.
Settings that suit JPG files
A few starting points, then adjust while watching the preview.
Logos saved as JPG
Use Logo / Icon, 4–6 colors, noise reduction on. If the logo sits on white, enable Transparent background — JPEG cannot store transparency, so this is how you get it back.
Line art and ink drawings
Scanned sketches trace much better in Black & White mode: one ink color, a threshold that decides what counts as a line, and no color noise at all.
Photographs
Use Photo mode with 16–24 colors. Accept that the result is a stylised, poster-like version — JPEG has already thrown away fine detail, and vector art cannot bring it back.
Badly compressed files
If the first attempt looks spotty, lower the color count and raise Smoothness. Fewer, larger shapes hide compression damage far better than many small exact ones.
JPG or PNG — which is better to trace?
If you have the choice, start from a PNG. JPEG's compression has already blurred the edges you are about to trace.
That said, most images on the web and in old brand folders are JPEGs, and they convert fine. The honest limit is detail: a heavily compressed 300 px JPG of a signature will never produce the same clean curves as a 1200 px PNG scan of the same page. When both exist, upload the PNG. When only the JPG exists, reduce noise, upscale once and let the tracer do its best — the Compare slider shows you immediately whether the shapes landed.
Frequently asked questions
Why does my converted JPG look speckled?
Those specks are JPEG compression artifacts — the faint blocks and halos the format leaves around edges are being traced as real shapes. Tick Reduce noise and convert again, and lower the color count a step or two. Both changes merge the noise into the surrounding color.
Can I add a transparent background to a JPG?
Yes. JPEG has no alpha channel, so the background is solid pixels. Enable Transparent background and Convertars removes the dominant background color while tracing, leaving an SVG logo you can place on any color.
Does converting a JPG to SVG restore the lost quality?
No. JPEG compression is irreversible, and tracing only reorganizes what is left into paths. What you gain is scalability and editability: the SVG stays sharp at any size, and you can clean up stray shapes in a vector editor.
Will a photo look photographic after tracing?
Not quite. Photo mode reduces the image to a limited palette, so the result looks posterized or screen-printed. That is the honest trade-off of vectorizing photographs: fewer tones, crisp shapes, plenty of graphic impact.
Are JPG files stored on your server?
For up to 30 days, yes. Uploads and results are kept that long to help improve the converter, then deleted automatically. They are never sold or shared, and no account is involved. The privacy policy (/privacy) explains what else is recorded.
