Does converting to PNG improve a blurry JPG?

No. Conversion cannot restore detail already lost from the source image.

Which format supports transparency?

PNG and WebP support transparency. JPG replaces transparent areas with a solid background.

Can I create an ICO file?

Yes. FilePebble can create a transparent 256 by 256 ICO from a supported image.

JPG vs PNG vs WebP: which image format should you use?

Changing an image extension does not automatically improve quality. Each format has different strengths, so choose the output based on what the image contains and where it will be used.

Use JPG for photographs and broad compatibility

JPG is widely supported and usually compact for photographs. It does not support transparency and uses lossy compression, so it is a weaker choice for logos, interface screenshots, or text-heavy graphics that need perfectly sharp edges.

Use PNG for transparency and crisp graphics

PNG preserves transparent pixels and sharp edges, which suits logos, diagrams, and screenshots. Detailed photos can become much larger than equivalent JPG or WebP files, so PNG should not be the automatic choice for every image.

Use WebP when modern web size matters

Choose WebP for modern websites and apps that support it when a smaller download is useful.
Choose JPG when compatibility with older software or upload forms is more important.
Choose PNG when transparency or lossless edges are essential, then open the converted file and check its background and detail.

Separate format from dimensions

Changing JPG to WebP can reduce size, but oversized dimensions may still dominate the download. Choose the needed width and height first, then select the format. This produces more predictable results than format conversion alone.

Keep an editable master

Do not use a repeatedly compressed web export as the only source. Retain the original photograph, design file, or lossless master. Create new delivery formats from that master whenever requirements change.
