Launch Animator →Signal Flag SVG Generator for Mariners, Cadets, and Designers
The signal flag SVG generator produces clean, infinitely scalable vector graphics of every flag in the International Code of Signals — the full alphabet set A through Z, numeral pennants 0 through 9, the three substitute flags, and the code/answering pennant. Each output is true vector SVG, so flags stay sharp from a thumbnail in a study deck to a wall-sized print in a training room.
Built for working mariners and the people who teach them, the tool removes the friction of hunting for accurate international maritime signal flag artwork. Colors, proportions, and shapes follow ICS specifications — square flags for letters, swallowtails for A and B, triangular pennants for numerals and substitutes — so what you download matches what’s flown at sea.
Everything runs in the browser. No installation, no account, no watermark. Generate a single Bravo flag for a safety poster, export the full Alfa-to-Zulu set for a curriculum, or pull a custom hoist into your slide deck — the workflow is the same: pick, generate, download.
Full ICS Flag Set
26 alphabet flags (A–Z), 10 numeral pennants (0–9), 3 substitutes, and the code/answering pennant. Nothing omitted.
True Vector Output
Pure SVG with correct ICS colors, shapes, and hoist-to-fly proportions. Scales to any size with zero loss of quality.
Instant Browser Download
No installation, no account, no plugin. Pick a flag, generate the file, save it to your device.
100% Free, No Watermark
Use generated SVGs in training materials, slide decks, and print without attribution or licence fees.
Signal Flag SVG Generator Built for Real Maritime Use
Maritime Cadets
Reinforce your International Code of Signals study with crisp, accurate flag visuals. Drop generated SVGs into flashcards, notes, or revision sheets and recognise every hoist before the exam.
Deck Officers
Build safety briefings, drill handouts, and bridge posters with vector flags that print sharp at any size. Faster than redrawing and more reliable than image searches that return inaccurate colors.
Maritime Instructors
Equip your classroom with consistent, ICS-compliant flag artwork for slides, worksheets, and assessments. One free tool replaces a folder of mismatched PNGs and licensed clip-art.
