Image Converter

About the Image Converter

Convert images between formats without installing anything or uploading your files. The converter opens JPG, PNG, WebP, GIF, BMP, ICO and SVG everywhere; AVIF in all current browsers; HEIC photos from iPhones in every browser (with its own HEIC decoder where the browser has none); TIFF and JPEG XL in Safari — and saves them as JPG, PNG or WebP (plus AVIF where the browser can create it).

Files are identified by their content, not their extension, so a WebP that was saved as “.jpg” is still handled correctly. Transparent areas are kept in PNG and WebP and filled with a colour you choose for JPG; SVG drawings are rasterised at the width you set, so logos stay sharp at any size.

Common uses

• Converting WebP or AVIF images saved from websites into JPG or PNG for apps, printers and older software.
• Turning SVG icons and logos into PNG at an exact width for slides, documents and app stores.
• Converting BMP, GIF and ICO files from old projects into modern formats.
• Making photos smaller by saving them as WebP.
• Converting HEIC photos from an iPhone to JPG or PNG, in any browser.

Which format should I choose?

• JPG — photos, maximum compatibility. No transparency: transparent areas are filled with the background colour.
• PNG — screenshots, logos, text and anything with sharp edges or transparency. Lossless, so photos become large.
• WebP — smaller files for the web, with optional transparency and a lossless mode. Google reports lossy WebP is 25–34% smaller than comparable JPEGs (WebP documentation). All current versions of Chrome, Edge, Firefox and Safari display it.
• AVIF — very efficient but newer; shown only when your browser can encode it.

Which formats can be opened?

Decoding is done by your browser, so support mostly depends on it:

• JPG, PNG (first frame of APNG), WebP, GIF (first frame), BMP, ICO and SVG — all modern browsers.
• AVIF — current Chrome, Edge, Firefox and Safari.
• HEIC/HEIF — every browser. Safari opens it itself; in Chrome, Edge, Firefox and on Android the converter uses its own HEIC decoder (libheif, 1.4 MB), downloaded once when you add the first HEIC photo, then running on your device. The main image of the file is converted, upright and in sRGB.
• TIFF and JPEG XL — Safari (iPhone, iPad and Mac). Other browsers show a message explaining what to do.

EXIF orientation is applied, so photos taken in portrait mode come out the right way up.

SVG to PNG, JPG or WebP

SVG files are vector drawings, so they can be rasterised at any size without losing sharpness. Leave SVG width empty to use the size stated in the file (its width/height, or its viewBox), or enter a width in pixels — the height follows the drawing’s proportions. External images and web fonts referenced by an SVG are not loaded (browsers block them in images), so embed them or convert text to outlines first.

Limitations

• Images up to 50 megapixels and 200 MB each, up to 100 per batch.
• Animated GIF, APNG and animated WebP files are converted to a single image (the first frame).
• TIFF and JPEG XL open only in browsers that can decode them (currently Safari).
• Outside Safari, the first HEIC photo needs a one-time download of the HEIC decoder (1.4 MB), so it cannot be converted without a connection before that.
• Metadata (EXIF, GPS, camera details) is not copied to the converted files, and colours are converted to sRGB.
• SVG files that rely on external images, web fonts or embedded HTML may render incompletely or cannot be exported.
