Frequently Asked Questions
Why do some emoji/characters appear as boxes?
The rendering machine doesn’t have a font with glyphs for those characters. System fonts on modern OSes have good Unicode coverage, but headless servers, older Linux, or stripped-down environments often lack emoji and CJK fonts.
Does it support transparent backgrounds?
Yes. Toggle Transparent. Works for PNG and WebP. JPEG has no alpha; composites on white with warning toast.
Why use this vs the text-to-WebP tool?
Same architecture, emoji-friendly defaults, Unicode emphasis. Either works.
Can I create transparent emoji stickers?
Yes. Turn on the Transparent toggle and export as PNG or WebP – both formats keep the alpha channel, so the sticker drops cleanly onto any background. JPEG flattens transparency, so use it only when you want a solid background.
How is canvas sized?
Auto-fit measures via Canvas measureText + padding. Manual locks to W×H.
Size limit?
Up to 4096 x 4096 pixels, large enough for print-quality stickers and high-DPI displays. Bigger canvases consume a lot of browser memory, which is why the cap exists.
Text uploaded?
No. The page makes zero network requests while you work – nothing is sent to a server, logged, or stored, and the tool keeps working offline once the page has loaded.
Offline?
Yes. The whole tool weighs about 22 KB, so once the page has loaded it runs without any network connection – every conversion happens locally in JavaScript on your device.
WebP support?
Detected at startup. Falls back to PNG with toast if needed.
Use for HTML images?
Yes – download PNG and embed in <img src="...">.
