What is the Image Format Converter?
Different apps and platforms expect different image formats — PNG for transparency, JPG for smaller photos, WebP for modern web pages. This tool loads an image using your browser's own image decoder and re-encodes it to whichever format you choose, with a quality slider for lossy formats, entirely on your device using the HTML canvas — no image is ever sent to a server.
Because it relies on your browser's built-in decoder, it can open any format your browser can already display natively (PNG, JPG, WebP, GIF, BMP, and in Safari, HEIC photos straight from an iPhone) and convert to PNG, JPG, WebP or BMP. If a format won't open, that means your specific browser cannot decode it locally — try the same file in Safari for HEIC, since only Safari currently decodes it without a plugin.

Questions people ask
Is my photo uploaded anywhere?
No, the image is decoded and re-encoded entirely in your browser using an HTML canvas; nothing leaves your device.
Can this convert HEIC photos from my iPhone?
Only if your browser can decode HEIC natively — currently that's mainly Safari. Chrome and Firefox cannot open HEIC files locally without a plugin, so the conversion will fail there and you'll see a clear message.
What's the difference between PNG and JPG?
PNG is lossless and supports transparency, better for graphics and screenshots; JPG is lossy and smaller, better for photos.
Does WebP work everywhere?
Nearly all modern browsers support WebP; very old browsers may not display it.
Is there a file size limit?
No hard limit is enforced, but very large images may be slow to process since everything runs in your browser.
