WebP to JPG
Convert a WebP image to JPEG with quality control; transparent areas are blended onto a background colour.
How it works
- 1
Drop your image onto the upload zone. The tool accepts the format shown in the accepted types for this page.
- 2
Adjust quality if the target format is JPEG or WebP, and pick a background colour if the source has transparency.
- 3
Click Convert — the output file downloads immediately and is processed entirely in your browser.
Questions
Why does JPEG conversion have a background colour option?
JPEG stores no transparency information. Without a background, semi-transparent pixels would map to their foreground colour at full opacity, producing dark fringes. Compositing onto a colour you choose produces the correct result.
What does the quality slider do?
It controls the JPEG or WebP encoder's compression level. Higher values preserve more detail at the cost of a larger file. PNG ignores the slider because PNG compression is always lossless.
Will converting to PNG make my file larger?
Often yes. PNG is lossless so it stores every pixel exactly, which typically produces larger files than JPEG or WebP for photographs. The size comparison below the result shows the real before-and-after numbers.
Does converting re-encode the pixels?
Yes. Every format change passes through the canvas, which re-encodes the image. EXIF and other metadata are not carried over to the output file as a side effect of this re-encoding.
Will my image be sent anywhere?
No. Everything runs directly in your browser on your own device. Your file never leaves your machine.

Build a multi-size .ico file from a PNG or JPG, choosing which pixel sizes to include — ideal for application icons and browser favicons.
Favicon Generator
Generate a full favicon set from one image: a three-size ICO, an Apple touch icon, PWA icons, a webmanifest, and the HTML.
SVG Converter
Rasterize an SVG file to PNG, JPEG or WebP at a scale factor you choose. The result is a pixel image — not editable vector paths.
SVG to JPG
Convert an SVG to a JPEG image at the export scale you set, composited onto a solid background colour — because JPEG has no transparency.
Adjust Brightness
Lighten or darken an image by shifting every pixel's brightness up or down with a single slider.
Adjust Contrast
Increase or reduce the difference between light and dark areas to make an image pop or flatten it.
Adjust Saturation
Boost or reduce the intensity of colours in an image, all the way from vivid to greyscale.
Rotate Hue
Shift every colour in an image around the hue wheel to change the overall colour cast.
