A photo slideshow on the big screen is one of the nicest ways to relive a holiday, share a wedding, or set a warm mood at a family gathering. The catch is that Android TVs are a little fussy about file formats, and phone photos are often too heavy to play smoothly. This guide explains the best format for an Android TV slideshow and gives you two free ways to build one — using the Image Compressor on Apps2Help.
The best format for an Android TV slideshow
If you want zero surprises, use JPEG (JPG). It plays in the built-in media player, gallery apps, and USB browser on virtually every Android TV and Google TV. PNG and WebP usually work too, but support can be patchy on older or budget models, so JPEG is the safe choice. One format to avoid is HEIC (what newer iPhones shoot) — most Android TVs cannot open it, so those photos need converting to JPEG first.
The simple route: JPEGs on a USB stick
This is the most foolproof method and needs no apps. Open the Image Compressor, add your photos, and let them shrink to a light JPEG size so they load instantly even on a basic TV. Download them, copy the JPEGs onto a USB drive, plug it into your TV, and open the gallery or media player — most will offer a one-tap slideshow that auto-advances. Compressing first matters here: full-size phone photos can stutter or take seconds to load per slide, while compressed JPEGs glide.
The premium route: a ready-made PDF or PPTX deck
If you want a single, pre-ordered show rather than loose files, use the same tool to build a deck. Choose Download All in PDF for a fixed slideshow, or Download All in PPTX for an editable presentation you can caption. To play these on the TV you will need a viewer app — a PDF reader, or WPS Office or Google Slides for the PPTX — or you can simply cast the file from your phone or laptop. This route looks the most polished and keeps every photo in the exact order you want.
Which should you choose?
For a quick, reliable show on any TV, go with JPEGs on USB. For a captioned, presentation-style slideshow — or when you are casting from another device — the PDF or PPTX deck is the nicer option. Both start from the same place: compressing your photos so they are light and TV-friendly.
