Free online image converters

Which converter should you pick?

Choose by where the file came from and where it has to go. The tool name tells you the direction, and each page explains what changes in the file.

HEIC to JPG is the fix for iPhone photos that will not open or upload elsewhere. WebP to JPG or PNG helps with images saved from the web. AVIF to JPG does the same for newer AVIF files. JFIF is just JPEG with another extension, and the JFIF tool repacks it.

Use PNG when you need transparency or sharp edges such as screenshots and logos, and JPG when you need a small photo. PNG to JPG makes files smaller but drops transparency. JPG to PNG does not restore detail that JPG already lost.

SVG to PNG renders a vector file at the size you choose with a transparent background, and SVG to JPG does the same on a white one when a form only accepts JPG. PNG to SVG traces simple logos and icons, and works best on flat shapes rather than photos. TIFF to JPG shrinks scans and camera files for sharing.

For animations and icons, WebP to GIF turns an animated WebP into a GIF that older apps can play, and GIF to PNG saves the frames as still images. PNG to ICO builds a favicon or a Windows icon from a PNG.

If you only want one file with many pages, see the PDF tools. If you are unsure, the image converter accepts many formats and lets you pick JPG, PNG, WebP, AVIF or GIF as the output.

JPG, PNG, WebP or AVIF: which format to save as

The output format decides file size, transparency and where the file will open. As a rule, save photos as JPG, graphics with sharp edges or transparency as PNG, and pictures for your own website as WebP or AVIF. Convert HEIC to JPG before you share it.
