Image Format Converter
Convert between WebP, PNG, JPG and AVIF in memory, then download with one click.
Convert WebP, PNG, JPG and AVIF Images Online
Different jobs need different image formats. WebP and AVIF are built for the modern web and produce the smallest files; PNG preserves transparency and sharp edges without any loss; JPEG remains the most universally accepted format for photographs. This converter moves your image between all of them in a single click, entirely inside the browser.
Conversion works by decoding your source file into a canvas and re-encoding the raw pixels into the target format with the browser’s own codecs. Because the codecs are native, output quality matches what the browser itself would produce — and because nothing is uploaded, conversion is effectively instantaneous.
Key features
- Four target formats — WebP, PNG, JPEG and AVIF where your browser supports it.
- Transparency handling — transparent areas are preserved for PNG and WebP, and flattened onto a colour you choose for JPEG.
- Quality control — set the encoder quality for lossy targets, or keep PNG fully lossless.
- Instant download — the converted file is generated as a Blob and saved with the correct extension automatically.
This tool runs entirely inside your browser using native Web APIs. Your files and text are never uploaded to a server, never logged and never shared with third parties.
How to use: Image Format Converter
- Select the source image
Drop in any image your browser can decode — PNG, JPG, WebP, GIF, BMP, AVIF or SVG. - Choose the output format
Pick WebP for web delivery, PNG for transparency and lossless graphics, or JPEG for broad compatibility. - Set the quality, if applicable
Lossy formats expose a quality slider. PNG ignores it because the format is always lossless. - Download the converted file
Click Convert & Download. The new file keeps the original name with the new extension applied.

Frequently asked questions
How do I convert WebP to PNG?
Drop your .webp file into the converter, choose PNG as the output format and click Convert & Download. Because PNG is lossless, no further quality is lost in the conversion.
Will converting to JPEG remove transparency?
Yes — the JPEG format has no alpha channel. Transparent pixels are composited onto a solid background colour, which you can set before converting. Choose PNG or WebP if transparency matters.
Can I convert SVG to a raster format here?
You can, but the dedicated SVG to PNG Converter is a better choice because it lets you set an explicit output resolution and scale factor, which matters for vector sources.
Why is AVIF sometimes unavailable?
AVIF encoding depends on your browser shipping an AVIF encoder. Chrome and Edge support it; Safari and Firefox currently decode AVIF but may not encode it. The option is hidden automatically when your browser cannot produce it.
