PNG Viewer Online
Drop one or more PNG (or JPG / WebP / SVG) files and view them at full size. Transparent regions are shown over a grey-on-white checkerboard so alpha is visible. Multiple files? Switch between them with the file picker. Nothing uploaded.

PNG / JPG / WebP / SVG — multiple allowed
What this is good for
- Quick preview without saving locally. Drop, look, close the tab.
- Verify transparency. The checkerboard shows exactly which pixels are transparent — no guessing whether your PNG has alpha or just a white background.
- Compare multiple files. Drop a batch, switch with the file picker.
- WebP / SVG quick-look. macOS Finder previews these badly; this tool just renders them.
FAQ
How do I open a PNG file online?
Drag it onto this page (or click to browse) — it renders instantly, with no software to install and nothing uploaded. The same works for JPG, WebP, and SVG.
How can I tell if a PNG is transparent?
Transparent areas appear over a grey-and-white checkerboard here; if you see a solid colour edge-to-edge, the image is opaque. For a definitive yes/no plus the alpha channel, run it through the image inspector.
Can I zoom in?
Browser zoom (Cmd/Ctrl + +) works on the rendered image. The viewer fits to about 70% of viewport height by default.
Why don't I see transparency for my PNG?
Either the PNG has no alpha channel (it's opaque), or the transparent regions are 100% opaque pixels that happen to match white. Run the file through PNG inspector to confirm.
Will it open large files?
Anything your browser can decode. Most laptops handle 50+ MB PNGs without trouble; very large (100+ MP) images may stutter.
