This universal image converter turns any picture your browser can open — PNG, JPG, WebP, GIF, BMP, AVIF, SVG, and even iPhone HEIC photos — into PNG, JPG, WebP, GIF, BMP, AVIF or SVG. Pick the output format, drop in the file, and download the result: the conversion happens on your own device, so the image is never uploaded and keeps working even offline once the page has loaded.
Each output has a job. PNG is lossless and keeps transparency, which makes it right for logos, screenshots and graphics. JPG is the universal photo format: small files, accepted everywhere, but it flattens transparency onto white. WebP is the modern web format — typically the smallest of the three at the same visible quality. For JPG and WebP a quality slider trades file size against fidelity; 92 is a sensible default that is hard to distinguish from the original.
A few outputs come with honest fine print. GIF is a single frame limited to 256 colours (an animated GIF converts its first frame); BMP is uncompressed, so files are large; SVG wraps your pixels in a scalable container rather than tracing them into true vectors; and AVIF encoding depends on the browser — Chrome and Edge can, Safari and Firefox cannot, and the tool says so rather than failing silently. HEIC output is the one direction no browser supports. Photos convert on first use a moment slower while the HEIC decoder loads. Nothing you convert is stored anywhere, and you can verify that in the Network tab.
Frequently asked questions
Which image formats can it convert?
Input: anything your browser can decode — PNG, JPG, WebP, GIF, BMP, AVIF, SVG, and HEIC/HEIF from iPhones. Output: PNG, JPG, WebP, GIF, BMP, AVIF or SVG. The one direction no browser supports is writing HEIC.
Does GIF, AVIF or SVG output have limits?
Yes, and they're stated up front: GIF output is a single frame with at most 256 colours; AVIF encoding works in Chrome and Edge but not Safari or Firefox (the tool tells you instead of failing silently); and SVG output embeds your pixels in a scalable wrapper — it does not trace a photo into true vector shapes.
Does converting reduce quality?
PNG output is lossless. JPG and WebP are lossy — the quality slider controls the trade-off, and 92 is visually indistinguishable from the original for most photos. Converting to JPG flattens transparent areas onto a white background, because JPG has no transparency.
Is my image uploaded anywhere?
No. Decoding and encoding both happen in your browser tab. You can load the page, disconnect from the internet, and still convert — which is the simplest proof the file never leaves your device.
