Sample Images for Testing

Ready-made images for testing: upload limits, rendering in a layout, resizing and compression, gallery and thumbnail behaviour. Sorted by resolution and by weight — from a single pixel up to 4K, and from a kilobyte up to 10 Mb. If you need a specific format with all its quirks, the links to the JPEG, PNG, SVG, GIF and WebP pages are below

🧠 Which image to pick for a test

To test upload limits, pick a file by weight — 1, 5 or 10 Mb — so that you hit the server limit rather than the image dimensions. For layout and resizing, resolution matters more: 4K and Full HD show how the picture holds up when scaled down and whether the grid breaks. A single-pixel image is handy as a placeholder and for checking that the file path works at all. PNG is heavier than JPEG at the same resolution because it compresses losslessly — at 4K the difference is tenfold.
