Hide a URL or message invisibly inside a photo's pixels and reveal it later — entirely in your browser. Or generate a share page (free sign-in required) so a photo posted on Facebook is clickable straight to your site.
Two unrelated problems, one page: making a photo carry a secret, and making a photo carry a link that actually works when Facebook gets involved.
Upload a photo, type the URL or message you want to hide, and click Hide Link In Photo. It's encoded into the least-significant bit of each pixel's color values — invisible to the eye — and you download the result as a PNG.
For Hide/Reveal, no — everything happens locally in your browser using the Canvas API, and the photo never leaves your device. The separate Share Page tool is different: it hosts your photo on our server (free sign-in required) since Facebook needs a public URL to fetch, not a raw file.
Only if the file stays an unmodified PNG. Re-saving as JPEG, resizing, screenshotting, or sending through an app that recompresses images will destroy the hidden data — download and share the exact PNG file this tool produces.
No — it's basic steganography, not encryption. Anyone with this tool (or general stego knowledge) can extract the hidden text. It's meant for fun, watermarking, or low-stakes hidden notes, not anything that needs real secrecy.
Facebook won't let a native photo upload be clickable — it always opens its own photo viewer. Instead, use the Share Page tab: enter your destination URL and a photo (upload one right there if you don't have a URL for it), and click Create Share Page. It's hosted instantly, ready to paste into Facebook — nothing to download or host yourself.
No. It works on Facebook, LinkedIn, X/Twitter, Slack, Discord, Telegram, WhatsApp, iMessage, and Reddit, which all render link previews from a page's meta tags. Instagram and TikTok don't make links clickable in regular posts at all, regardless of what tags a page has — only a bio link, a Stories link sticker (Instagram), or paid ads carry an outbound link on those platforms.
Yes — once signed in, the Share Page tab shows a "My Share Pages" list below the form with every page you've created, its view count, and a delete button. Deleting one breaks its link immediately, including anywhere it's already been pasted.
Upload any common image format (JPEG, PNG, WebP) — the tool converts it to PNG on output, since only an uncompressed format like PNG preserves the hidden bit pattern.
Yes — the amount of data you can hide scales with the image's pixel count, so a larger photo can carry a longer message than a small one.
No — once created, a Share Page is hosted continuously and works for anyone who clicks it, whether or not you're signed in at the time.
