JPGJPEG (Joint Photographic Experts Group)

The most widely used photo format, introduced in 1992. Its lossy compression keeps files small, and it opens everywhere: phones, computers and social networks. It does not support transparency.

WEBPWebP

A format created by Google in 2010 to make the web lighter. It compresses with or without loss, supports transparency and animation, and files are often 25–35% smaller than a JPG of the same quality.

GIFGraphics Interchange Format

A 1987 format limited to 256 colours. It is still the favourite for short looping animations, but it is a poor fit for photos.

Compression
Lossless, 256 colours
Transparency

Animation

Convert to

BMPWindows bitmap

The classic Windows image format, usually uncompressed. Files are very large, so it is usually converted to JPG or PNG to save space. Formatomat writes 24-bit BMPs, which every program reads, but without transparency: transparent areas become white, and a message says so.

ICOWindows icon

AVIFAV1 Image File Format

A recent image format (2019) based on the AV1 video codec. It compresses even better than WebP and supports transparency, but some apps and websites do not accept it yet.

HEICHigh Efficiency Image Container (HEIF)

The default photo format on iPhone since iOS 11 (2017). It can be half the size of a JPG of the same quality, but Windows, many websites and plenty of apps cannot open it.

Compression

Frequently asked questions

Are image conversions really free?

Yes: no sign-up, no watermark and no limit on the number of files. The work happens on your device, so it costs us nothing in servers.

Are my files sent anywhere?

No. They are read and converted right in your browser. You can even go offline once the page has loaded: conversions you have used since the site’s last update keep working.

Is there a size limit?

A file’s size has no fixed limit: it depends on your device’s memory and on the browser. A few hundred MB work well on a recent computer. On a phone, stick to lighter files, especially for video. Most conversions read the whole file: beyond a certain size, often about 2 GB (less on a phone), the browser cannot read it in one block, and a message gives the file’s size.

A few caps still protect the browser’s memory, including: 1 GB of unpacked data for an archive or a Word, Excel, OpenDocument or EPUB file (512 MB on a phone and on some devices with little memory), 20,000 files per archive, 5 million filled cells per workbook, and 500 pages for a TIFF converted to PDF. A file over a cap is not converted, and a message says so.

Which browsers work?

The page is designed for recent versions of Chrome, Edge, Firefox and Safari. Video conversion (MP4, WEBM, MOV, MKV) uses WebCodecs, a feature of Chrome and Edge and of recent versions of Safari and Firefox (except Firefox for Android, which does not have it yet). A conversion the browser cannot do is refused with a message that says so.
