Transparency
Transparent PNGs without a background
Need an image without a background — logo, badge, or watermark? Create PNG or WebP with adjustable opacity and preview it on a checkered background.
Check semi-transparency on purpose
Many bugs only show up with light transparency: dark edges, broken previews, or images that get flattened by mistake. A controlled test image makes that reproducible.
PNG and WebP
Pick the format your system expects. PNG is the most compatible; WebP with transparency is common in modern browsers.
Work with it next
Convert the file in the format converter or inspect details in the image inspector — in the same toolbox.
Badges, logos, and watermarks
Transparent test images work for stickers on photos, logo slots, and CSS masks. The checkered preview shows whether transparency is really there.
Check your upload
Upload a transparent PNG into your converter and see whether transparency survives or gets lost — a common production bug.
FAQ
WebP or PNG?
PNG for maximum compatibility; WebP when your stack already serves that format.
Can I control opacity?
Yes — the generator lets you set opacity deliberately.
