BMP to SVG Converter

How to Convert BMP to SVG Online

1. Upload Your BMP File: Drag and drop or click "+ Add Files" to load one or more BMP images. Only .bmp files are accepted on this page — for .jpg or .png start at JPG to SVG or PNG to SVG. Batch upload is supported; every file is traced in your browser session.
2. Check the Source (Optional but Recommended): Vector tracing rewards clean input. If your BMP is a screenshot with anti-aliased edges, upscale or threshold it in an image editor first; if it's a photo, BMP to PNG is almost always the better destination. The cleaner the colour regions, the smaller and tidier the resulting SVG paths.
3. Set Number Precision: Default is 6 on a 1-10 slider. This controls the decimal places written into each SVG path coordinate — higher precision (8-10) keeps tiny curve detail at the cost of a larger SVG, lower precision (1-3) snaps coordinates to a coarser grid and shrinks the file. 4-6 is the recommended sweet spot for logos and icons.
4. Convert and Download: Click Convert. Each BMP runs through a vector tracer that detects edges, clusters similar-colour regions, and emits SVG <path> elements. Download files individually or as a ZIP. No sign-up, no watermark, no email gating.

Why Convert BMP to SVG?

BMP is Microsoft's uncompressed (or optionally RLE-compressed) raster format, native to Windows since version 3.0 in 1990. Each pixel is stored explicitly, so a 1024×1024 24-bit BMP weighs 3 MB before any header overhead and pixelates the moment you scale it past its native size. SVG, standardised by the W3C since 1999 (SVG 1.1 Second Edition was given Recommendation status on 16 August 2011), describes shapes as XML paths — geometry, not pixels — so the same logo prints crisp on a business card or a billboard from one file.

Tracing a BMP to SVG only makes sense for art that should have been vector to begin with. Typical wins:

• Logos rescued from old documents — A BMP logo embedded in a 1990s Word doc or Windows clipart library traces to a 5-30 KB SVG that scales cleanly for a modern website header or favicon.
• Cricut, Silhouette, Glowforge, and other cutters — Cricut Design Space accepts SVG, PNG, JPG, BMP, and GIF, but SVG is the preferred upload because cut paths come through as discrete layers ready to assign per-colour materials. Tracing a scanned bitmap is the standard workflow when the original vector file is missing.
• Icon and UI work — A 64×64 icon BMP traced to SVG drops cleanly into React/Vue components, CSS backgrounds (data URI or <img src>), and Figma — sharp on every DPR, from a 1× laptop screen to a 3× Android phone.
• Print preflight — Print shops reject low-resolution raster art; a vector trace from a 300-dpi BMP gives the press room geometry it can rasterise at any output resolution.
• Web performance — A solid-colour BMP logo at 100 KB typically traces to a 5-20 KB SVG, inlines as a data URI without an extra HTTP request, and stays sharp on retina/HiDPI displays where the raster would look blurry.
• Embroidery, vinyl decals, screen printing, laser engraving — All of these production workflows want vector paths so each colour or stroke can map to a separate tool head, screen, or laser pass.

For animation or interactive states, SVG also exposes every shape to CSS and JavaScript — something a flattened BMP can never offer.

Frequently Asked Questions

Will a photograph in BMP convert nicely to SVG?

Almost never. Vector tracers work by clustering same-colour regions and drawing outlines around them — a photograph has thousands of continuous tonal transitions, so the tracer either produces a posterised "paint-by-numbers" approximation or an enormous SVG full of micro-paths. For photos, keep the raster: BMP to PNG for lossless or BMP to JPG for the smallest file.

Why does my output SVG still look pixelated when I zoom in?

The trace is genuine vector geometry — you're almost certainly looking at the preview in an image viewer that's rendering it at a fixed resolution. Open the SVG in a browser, Inkscape, or Illustrator and zoom in there; the paths stay sharp at any zoom. If the trace itself shows visible "stair-stepping" in a vector editor, raise the precision slider to 7-8 and re-convert.

Can I edit the SVG after conversion?

Yes. SVG is plain XML — open it in any text editor to tweak fill, stroke, or path data, or drop it into Inkscape (free), Adobe Illustrator, Figma, Affinity Designer, or Sketch. You can also restyle colours from CSS when the SVG is inlined into a webpage, which a BMP never permits.

Will my SVG keep the BMP's transparency?

Only if the source BMP is a 32-bit BMP with a real alpha channel (BITMAPV4HEADER or later — most BMPs in the wild are 24-bit and have none). Where alpha is missing, the tracer treats the existing background as another colour region. For best results pre-process in an editor: knock out the background to true transparent, save as 32-bit BMP or convert to PNG first, then trace.

How small does the SVG get compared to the BMP?

Two-colour logos routinely shrink 90-95% (a 500 KB BMP → 25 KB SVG). Multi-colour illustrations land around 70-85%. Photos grow on conversion, which is one more reason not to trace them. Gzipping the SVG (or saving as .svgz) trims another ~70% on top.

Should I use SVG instead of PNG on my website?

For logos, icons, UI glyphs, and flat illustrations — yes. SVGs scale to any DPR, can be styled with CSS (changing colour by class, hover state, dark mode), and are usually smaller than equivalent PNG@2x assets. For photographs or screenshots, stick with PNG, JPG, or WebP — see SVG to PNG if you ever need to flip back.

Will the SVG work in Cricut, Silhouette, or Glowforge?

Yes, with caveats. Cricut Design Space, Silhouette Studio, and Glowforge all import SVG natively. Cutters expect closed paths with clear fills, so very low precision (1-2) can leave gaps and very high precision (9-10) can produce micro-segments that confuse path planning. Stick to 4-6 unless you're seeing specific cut-quality issues, and ungroup/clean up stray nodes in the design app before sending to the machine.

My logo has anti-aliased edges from the original screenshot — will the trace pick them up as extra colours?

Yes, and it's the most common cause of "noisy" SVG output from BMPs. Anti-aliasing introduces dozens of edge-pixel colours that the tracer treats as their own regions, producing tiny halo paths around every shape. Pre-process the BMP in an image editor: threshold or posterise to flatten near-identical colours, or upscale the image 2-3× and trace from there so the AA pixels become an insignificant fraction of each region.

Is there a file size limit?

The conversion runs in your browser session — there's no upload cap to a server. Practical ceilings are set by your device's memory; very large BMPs (50+ MP) can take a while to trace because every pixel goes through edge detection. For workflows with thousands of files, batch them in groups of 20-50.
