Almost everyone planning an event asks this question: is a WhatsApp group enough for collecting guest photos, or is a shared Google Photos album worth it? And when does it make sense to reach for a purpose-built tool like Pixelka? A comparison on five criteria that matter in practice.
Does a guest need to install anything or have an account?
A WhatsApp group needs an app and a phone number — it works for a circle of people you know, and fails for foreign guests without a Slovak number. A Google Photos album needs a Google account, which not every older relative or overseas colleague has. A gallery link works straight in the browser, nothing to install.
Photo and video quality
WhatsApp compresses photos to a fraction of their original size on send, and video often doesn't even play the sound back correctly. Google Photos keeps the quality, but in a shared album a guest without an account can often only view, not always easily upload. A tool built specifically for this job (photos up to 20 MB, video up to 200 MB, full original quality) removes that trade-off entirely.
A live slideshow on the dance floor
This is the biggest practical difference. Neither a WhatsApp group nor a Google album can project photos live onto a screen during the evening — you'd have to manually download them and build a slideshow yourself. A tool with a live slideshow shows a guest's photo on the TV or projector within seconds of upload — and that exact moment is what motivates guests most to keep taking photos and uploading.
Guest language and international weddings
Both WhatsApp and Google Photos show their interface based on a guest's phone language — which, at an international wedding, means a mix of languages and instructions part of your guests won't understand. A gallery with a language switcher built right into the page (Slovak, Czech, Hungarian, German, Polish, English) solves this with one link for every guest at once.
Where your data actually sits
WhatsApp belongs to Meta (servers in the US), Google Photos to Google (also outside the EU in most regions). A tool with data stored in the EU (Germany or Slovakia, for example) has a much simpler GDPR position — especially important at company events, where the compliance department will ask about exactly this.
In short
For ten friends on a trip, a WhatsApp group is enough. For a wedding, company event, or conference with dozens to hundreds of guests, a tool built specifically for this purpose pays off — see the full comparison, pricing included, on one page.
