Free Code 39 Barcode Generator

Host your PDF anywhere — Google Drive (use the "anyone with link" share URL), Dropbox, your own server, S3, etc. Paste the public link here. We encode the URL so the QR works forever and never depends on us. Tip: for Google Drive, replace /view in the share URL with /preview for a cleaner mobile view.

Any downloadable file — installer, archive, document, dataset. Host it anywhere; we encode the URL. The user's browser handles the download per its own MIME-type rules.

JPEG, PNG, WebP, GIF, or HEIC — host it anywhere. Mobile browsers open the image full-screen; desktop browsers show it inline.

YouTube and Vimeo URLs open natively in their apps on phones. Direct .mp4 / .webm files open inline in any modern browser.

MP3 / OGG / WAV / FLAC / M4A direct URLs play inline in mobile browsers. Spotify (open.spotify.com/track/…) and SoundCloud (soundcloud.com/…) URLs open in their apps. Apple Music / Bandcamp / Tidal links also work.

Restaurant / cafe / bar menu — point to a PDF, an HTML menu page, or your online-ordering platform (Toast / Square / DoorDash / Uber Eats). Print on table tents, host signs, or window stickers. Pro tip: use a frame ("Scan our menu") so customers know what to do.

Paste your form's share link — either the short forms.gle/… or the long docs.google.com/forms/d/e/…/viewform form. We auto-prefer forms.gle when both are available since the shorter URL produces a denser QR. Works for surveys, registrations, RSVPs, lead capture, classroom polls.
