HEIF to SVG
Turn HEIF photo files into SVG vector image files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.
How to do it
- Download Asteria and open it. It's free and needs no account.
- Drop your HEIF files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
- Type trace to svgand press Enter. SVG outline traced from a bitmap.
- The first time, Asteria asks to download Potrace, a free add-on from Peter Selinger, under the GPL-2.0-or-later license. It shows the download size before you say yes, and needs no administrator password.
- Press ⌘↵ (Ctrl ↵ on Windows) to save. The SVG files appear next to the originals, which stay exactly as they were.
Threshold: darkness cutoff (1-99), default 50.
What it needs
HEIF to SVG uses Potrace, a free program for tracing pictures into vectors. Asteria doesn't bundle it. The first time you need it, Asteria offers to download it, checks the download against a pinned checksum, and keeps it in its own folder, where Settings can remove it again. If Potrace is already on your computer, Asteria uses that copy.
How it was tested
A real HEIF file was converted on Linux, and the SVG that came out was opened and checked with Python parser to make sure it is what it says it is.
