Higher Quality Than Browser Conversion
We use industry-grade open-source tools — ImageMagick, libheif, libavif, libjxl and OpenJPEG — to deliver output quality that browser-based converters can't match.
Convert SVG to ICO online for free. The vector is re-rendered at 512 px or larger first, then all six icon sizes — 256, 128, 64, 48, 32, 16 — are scaled down from it rather than blown up. No signup, no watermark, no limits, files auto-deleted 1 hour after upload.
When you build an icon from a PNG, the sharpness ceiling is however many pixels that PNG has. Feed in a 64x64 image and the 256 entry can only be an upscale. A vector has no such ceiling: it stores shapes, not pixels, so rendering it larger is simply a fresh calculation. Whenever the vector source is available, it is the better starting point for an icon — which is a large part of why this route has been picking up lately.
There is one trap worth naming up front. Rasterisers render an SVG at whatever width and height the file itself declares, and icon SVGs almost universally declare width="24". Render at that size and you get a 24-pixel grid, after which all six icon sizes are upscales again — the whole advantage of the vector thrown away. PicEditLab checks the rendered result at this step and, when the longest side falls short of 512, renders the original vector again at the larger size. That second pass is a re-render, not an enlargement: the paths are recalculated, so nothing is lost.
Browsers do accept SVG favicons directly now — a link tag in your head with type set to image/svg+xml is all it takes, and you can even make the icon follow dark mode with a CSS media query. But /favicon.ico in your site root is still the path browsers request on their own without reading any HTML, and it is what Safari bookmarks, Windows desktop shortcuts and most crawlers look for. The practical answer is to ship both: SVG for the browsers that use it, ICO to cover everything else.
A vector guarantees clean edges, but it cannot rescue a design that is simply too busy. At 16x16 a letter is about a dozen pixels tall, and hairlines, gradients and small interior text collapse into mush at that size no matter what format they came from. If your icon is unreadable when small, the fix is in the artwork: thicken the strokes, drop the interior detail, keep only the silhouette that people actually recognise.
Just need a plain bitmap? Convert SVG to PNG instead
No technical knowledge needed. Free, fast, and available on any device.
Built on top of multiple proven open-source conversion engines. We pick the best processing chain for each format combination, avoiding the color shifts and quality loss common in browser-side conversion.
Converting SVG images to ICO comes up in many situations: making files compatible with a different device or platform, reducing storage footprint, or preparing images for upload to a service that does not accept the source format. The traditional approach is to install Photoshop, GIMP or a similar desktop application — overkill for an occasional task. Browser-based converters are an alternative, but they are limited by what your browser can natively decode and cannot handle specialty formats like RAW, HEIC or AVIF at all. PicEditLab runs the conversion server-side, so format support, output quality and processing speed do not depend on your browser or device.
Conversion on PicEditLab takes three steps — upload, pick the target format, download:
Our server runs a proven open-source toolchain. ImageMagick handles color space conversion and resampling, libheif uses the x265 codec for HEIC encoding and decoding, libavif uses AOM for AVIF, libjxl handles JPEG XL, OpenJPEG covers JPEG 2000, and dcraw decodes raw sensor data from RAW files. JPG output uses quality 85 with progressive encoding for faster perceived loading on the web. PNG output uses zlib at maximum compression to keep file size as small as possible without losing a single pixel of detail.
