Every GIS user eventually faces the same file-format question: shapefile or GeoPackage? Shapefile is the format everyone recognises, supported by every GIS tool ever made, and still the default export in many workflows. GeoPackage is the modern, open standard built on SQLite, and it fixes nearly every shapefile limitation. For new projects in 2026, the answer is usually GeoPackage, but the reasons deserve a proper look.

Shapefile's staying power comes from ubiquity. It has been around since the early 1990s, every GIS package reads it, and countless government datasets are distributed in it. But its design shows its age: a shapefile is actually three or more separate files that must travel together, attribute names are limited to ten characters, file size caps at two gigabytes, and it cannot store raster data, multiple layers or proper null values. A single missing sidecar file corrupts the dataset.

GeoPackage solves these problems by storing everything in one SQLite database file. One file can hold multiple vector layers, raster tiles, attribute tables and styling, with no ten-character field name limit, no practical size cap, and full support for null values and spatial indexes. Copying a GeoPackage is copying one file, which ends the familiar disaster of a shapefile arriving without its projection or database component.

Performance also favours GeoPackage. Spatial indexes make queries and rendering faster on large datasets, and the single-file design reduces file-system overhead. For web and mobile workflows, GeoPackage's SQLite base means it can be read by apps and libraries far beyond desktop GIS, including Android's native support. QGIS treats GeoPackage as its default format for good reason.

Compatibility is the one area where shapefile still wins. Some older government systems, legacy scripts and specialised tools expect shapefiles and nothing else, and some data portals still distribute shapefiles exclusively. In those cases, exporting a shapefile copy for delivery while keeping GeoPackage as your working format is the pragmatic approach. Conversion in QGIS takes seconds and loses nothing that matters for most deliveries.

A sensible rule for 2026: use GeoPackage for everything you create, store and analyse, and export shapefile only when a recipient or system demands it. Keep field names descriptive, since GeoPackage allows it, and organise related layers into a single GeoPackage per project rather than scattering dozens of shapefiles across folders.

Migration is painless. In QGIS, right-click a shapefile layer and export it to GeoPackage, or use the package layers tool to convert a whole project at once. Check that field names survived in full, since shapefile truncation may have mangled them years ago, and treat the conversion as a chance to clean up attribute names properly.

Formats come and go, but the principle behind this choice lasts: pick the format that loses the least information and causes the fewest accidents. In 2026, for vector GIS data, that format is GeoPackage, and shapefile's role is increasingly that of a legacy interchange format rather than a working standard.

If you work with a team, agree the format question once and write it down: GeoPackage for working data, shapefile only on export when a partner requires it, and a short note in the project readme explaining the choice. Format debates waste surprising amounts of project time when they are relitigated per dataset, and a one-line policy ends them permanently. When in doubt, keep the GeoPackage as the master copy and treat every shapefile export as a disposable delivery format, never the other way around. That single habit protects you from the classic shapefile failure, where a dataset arrives incomplete because one of its sidecar files was left behind in an email attachment or a shared folder.
