Strava still hasn’t added a native “Lifetime Gallery” grid, but the best way to see all your photos at once is through the personal heatmap on their desktop website. Once you toggle on the photo visibility in the map settings, you can see exactly where every shot was taken and click through to the original activity. Many power users also connect their accounts to VeloViewer, which provides a massive, searchable grid of every image you’ve ever uploaded.
If you decide to download these old photos for a project, you might find they are saved as WebP files to save server space. Since some editors or sites don’t support that format, you can use webptojpghero to quickly flip them into high-quality JPEGs while keeping the original resolution intact.
