What you get

Simple tools, clear results, no unnecessary steps

Transparency handled correctly

Transparent PNGs and WebP files keep their clear background when the chosen format supports it. JPG exports use a clean white background instead of unexpected dark edges.

Nothing is uploaded

Your image stays on your device and is never stored by Spira, so you can convert private or client files with confidence.

Your file never leaves the device

Your image stays private on your device. It is never uploaded or stored by Spira.

No account needed

Start immediately with no sign-up, email address or watermark.

Fast and easy to retry

See results quickly and try as many settings as you like until the image looks right.

Which format for which job

Choose PNG for transparency, logos, screenshots and crisp text. Choose JPG for photographs and broad compatibility. Choose WebP when you want a smaller image for the web without giving up good visual quality.

Why WebP is usually the answer for the web

WebP is a strong choice for websites because it usually keeps files smaller at similar quality. Choose PNG for transparency and crisp graphics, or JPG for photos that must work with older tools, print services or upload forms.

FAQ

Does converting PNG to JPG lose quality?

JPG can soften fine text and sharp edges, but photographs usually look unchanged at the default quality. Use PNG or WebP for logos, screenshots and graphics with crisp lines.

What happens to transparency?

Converting to JPG flattens transparent areas onto white, because JPG cannot store them. PNG and WebP both keep the alpha channel intact.

Is my image uploaded anywhere?

No. Your image stays on your device throughout the conversion and is never uploaded or stored by Spira.

Is there a file size limit?

Images up to about 40 megapixels are supported, which covers typical phone and camera photos. Very large files may depend on the memory available on your device.

When the image is only the start

Spira AI takes a script or a link and produces a finished short with voiceover, visuals and captions, then publishes it on a schedule. These small tools are the pieces you reach for along the way.
