Add your PGM file
Drop one or more .pgm files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
PGM to SVG
Tracing a .pgm image to .svg redraws it as outlined colour shapes, so the result can be scaled, recoloured, or fed to a cutter or embroidery digitizer. Free, private, and validated — the file never leaves your browser.

Tracing a .pgm image to .svg redraws it as outlined colour shapes, so the result can be scaled, recoloured, or fed to a cutter or embroidery digitizer. A .pgm file is a Portable Graymap: a single-channel greyscale image storing one intensity value per pixel, with the maximum value declared in the header. It is the middle rung of the Netpbm ladder — richer than a one-bit bitmap, simpler than a colour pixmap.
An .svg file is a Scalable Vector Graphics document: an XML text file describing shapes, paths, text, and gradients mathematically rather than as pixels. Because the geometry is resolution-independent, one .svg renders razor-sharp at any size, from a 16-pixel favicon to a billboard. For this route the practical draw is infinite scalability with no quality loss at any zoom or resolution and tiny file sizes for geometric artwork compared with high-resolution rasters — balanced against utterly unsuited to photographs, which have no economical vector representation, which is worth knowing before you commit a large batch.
Why convert PGM to SVG?
Tracing is what you reach for when a .pgm file is the only copy of a logo, badge, or line drawing you have, and you now need it sharp at any size — a large print, a vinyl or laser cut, or the vector outline an embroidery digitizer starts from. Flat-colour artwork traces cleanly; photographs do not, because there are no crisp colour boundaries for the tracer to follow. Expect to tidy the result in a vector editor for production work.
PGM vs SVG at a glance
| Aspect | Portable graymap (.pgm) | SVG vector (.svg) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Vector — resolution-independent geometry instead of pixels |
| How it stores data | p2 stores samples as whitespace-separated ASCII integers; P5 stores them as raw bytes | plain XML: elements like <path>, <rect>, <circle>, and <text> with a d-attribute path language for arbitrary curves |
| Strongest at | machine vision and image-processing pipelines that operate on intensity alone | logos and brand marks that must stay crisp at every display density |
| Weak spot | uncompressed, so files are large relative to PNG for the same data | utterly unsuited to photographs, which have no economical vector representation |
| Metadata | none beyond header comments. No colour profile, no EXIF, no acquisition metadata — anything an instrument recorded alongside the pixels has to travel in a separate file | metadata travels as XML: <title> and <desc> elements aid accessibility, a <metadata> element can hold RDF or XMP, and Creative Commons licensing blocks are common in Inkscape output; EXIF does not apply |
Pick SVG as the output
Select .svg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if SVG is selectable, the route is real and validated.
Convert on your device
Press Convert. An image tracer running in local JavaScript groups the pixels into flat colour regions and fits outline paths around them, entirely inside your browser.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid SVG file. Outputs keep the original filename with the .svg extension.
PGM to SVG questions, answered
Will converting PGM to SVG lose quality?
Tracing is an interpretation, not a lossless conversion: the .pgm pixels are grouped into a limited set of flat colours and redrawn as outlines, so gradients band, soft edges harden, and fine texture disappears. The quality slider controls how many colours and how much detail survive. The payoff is that the .svg result then scales to any size without ever pixelating.
Is it private to convert PGM files here?
Yes — the .pgm file is processed inside your browser tab and never uploaded. An image tracer running in local JavaScript groups the pixels into flat colour regions and fits outline paths around them, entirely inside your browser. Close the tab and the file is gone from memory.
Where will the SVG file work?
Every modern browser renders SVG natively, inline in HTML or as an image source, and design tools from Illustrator and Figma to Inkscape treat it as a first-class format. Gaps appear in contexts expecting rasters — email clients, older office software, some CMS uploaders — which is when rasterizing to PNG at a chosen resolution becomes necessary.
Will the SVG file be bigger or smaller than my PGM?
It depends entirely on the artwork. A flat logo or line drawing traces to a handful of paths and often lands far smaller than the .pgm source. A photograph produces thousands of paths and can be many times larger — if that happens, lower the quality to trace fewer colours, or accept that the image is not a good tracing candidate.
What happens to the metadata in my PGM file?
In .pgm, none beyond header comments. No colour profile, no EXIF, no acquisition metadata — anything an instrument recorded alongside the pixels has to travel in a separate file. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert SVG back to PGM?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .pgm → .svg → .pgm is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
