Convert PNG, JPEG, and WebP — all in your browser.
About Image Format Converter
Image Format Converter switches images between PNG, JPEG, and WebP — the three formats nearly every browser, app, and operating system understands. It is the tool you reach for in the everyday moments when an upload form rejects PNGs, a JPEG needs transparency, or a photo needs to be a smaller WebP for a website.
Worked example: drop in a PNG screenshot and pick JPEG to get a much smaller version at typical quality settings — at the cost of transparency, which JPEG cannot represent and which is flattened onto a white background. Pick WebP instead and you get a similarly small file with transparency preserved. Going PNG → WebP at quality 92 typically yields a file half the size or smaller with no visible difference from the original.
A few practical notes. PNG is lossless and supports transparency — ideal for logos, icons, screenshots, and anything with sharp edges or flat color. JPEG is lossy and has no transparency, but produces compact files for photographs. WebP combines both worlds (transparency support plus smaller files at the same visual quality) and is now supported by every major modern browser; the canvas WebP encoder this tool uses produces lossy WebP at a high default quality. For format pairs outside the big three (HEIC, AVIF, GIF, BMP, ICO, SVG → raster), the site has dedicated per-pair converters; this is the standalone three-way converter for the most common cases.
All conversion runs locally in your browser via canvas. The source image is never uploaded, which matters for personal photos and unreleased design assets.
