OneTaskImage Converters
HEIC to JPG, WebP to PNG, SVG to PNG and STL to GLB
Convert a photo or graphic to the format the next program wants. Turn an iPhone HEIC into a JPG, a WebP download into a PNG, a vector SVG into a raster image, or a whole batch into WebP to make a page load faster. Everything is decoded and re-encoded in your browser.

Choosing a format
JPG suits photographs, where small losses are invisible and the file stays small. PNG keeps every pixel exactly and supports transparency, which suits screenshots, logos and anything with text. WebP and AVIF do both jobs at smaller sizes and are supported by every current browser, though some older desktop software still cannot open them, which is the usual reason to convert back.
HEIC from iPhones
iPhones save photos as HEIC by default. It is efficient, but Windows and many websites do not accept it. The HEIC pages decode the file in the browser and save a JPG or PNG, and the photo never leaves your device.
Vector to raster
SVG drawings are described as shapes, so they scale to any size. Converting to PNG or JPG fixes them at a chosen pixel size, which you set before exporting so the result is sharp at the size you need.
3D models
STL and OBJ are the common formats for 3D printing and modelling. GLB packs a model and its materials into one file that web viewers, game engines and AR tools load directly, and the 3D converters produce it in the browser.
