Comparison
PartyLab vs LINE
LINE is a messaging platform. PartyLab is a purpose-built event gallery where every guest uploads original-quality photos with a single QR scan — no LINE account, app download, or phone number required.

The LINE problem at events
LINE is a messaging app — not an event gallery
LINE is built for one-to-one and group chat. When guests share photos in a LINE group, they disappear into a scrolling message thread with no dedicated gallery view, no lightbox for full-screen browsing, no slideshow for displaying photos on a TV, and no bulk download for the host. LINE Albums exists as a workaround, but it still requires every contributor to have the LINE app and a LINE account, and the album UI is buried inside the group chat interface rather than being a primary feature.
LINE compresses photos sent in chat
Photos sent directly in a LINE chat are compressed by default — LINE reduces file size to keep messages fast, which means you lose the original resolution that makes printed photos, framed shots, and keepsakes look their best. While LINE Keep can store files at higher quality, it requires additional steps most guests will not take at an event. PartyLab stores every upload at 100% original quality with no compression applied, and every file is available at original resolution for download.
Non-LINE users are completely locked out
LINE has 178 million monthly active users, predominantly in Japan, Taiwan, Thailand, and Indonesia. But at a mixed event — a destination wedding, an international reunion, a multicultural birthday — guests who don’t use LINE cannot contribute photos at all. PartyLab works in any mobile browser on any device globally: guests scan the QR code and upload in seconds regardless of whether they use LINE, iMessage, WhatsApp, or any other messaging platform.
Hosts who made the switch
“We tried using our LINE group to collect photos from my daughter’s birthday party but the photos got buried in stickers and messages and half the guests didn’t have LINE. PartyLab was a revelation — one QR code at the entrance and we had 300 photos by the end of the night.”
Yuki T.
Parent, birthday party host
“Our company event in Tokyo had guests flying in from the US and Europe. Our local colleagues all use LINE but the international guests didn’t. PartyLab worked for everyone regardless of which messaging app they use.”
Kenji N.
HR Manager, corporate events
“I wanted original-quality photos from our family reunion but LINE compresses everything. PartyLab gave us full-resolution uploads and I could download everything as one ZIP file. No other tool came close.”
Mei L.
Family reunion organizer
Frequently asked questions
Can I use a LINE group to collect event photos from guests?
You can share photos in a LINE group chat, but every guest needs the LINE app and a LINE account. Photos land in a message thread that is compressed by default, with no gallery view, no slideshow, and no bulk download. Guests without LINE are completely excluded. PartyLab is purpose-built for group photo collection: one QR code, guests upload in any browser, photos land in a live gallery with slideshow and ZIP export included.
Does LINE compress photos?
Yes — photos sent in LINE chat are compressed to reduce file size. While LINE Keep can store some files at higher quality, it requires extra steps most guests will skip. LINE Albums is a workaround but still requires the LINE app and account. PartyLab stores every upload at 100% original quality with no compression, and every file is downloadable at original resolution.
Is LINE free while PartyLab costs money?
LINE is free to use. PartyLab is also free for events up to 30 photos. For unlimited uploads, 12-month gallery retention, ZIP export, and a built-in TV slideshow, PartyLab is $19 one-time with no subscription and no per-user cost.
What if some of my guests don’t use LINE?
Guests without LINE cannot join a LINE group or contribute photos. At international events, family gatherings with older relatives, or any event with a mixed audience, this exclusion can be significant. PartyLab works in any mobile browser on iOS, Android, or desktop — no app, no account, no platform dependency.
