Three steps to your converted file

Everything happens in your browser tab - upload, pick a format, download. The heavy lifting runs on our servers.

Drag and drop, click to browse, or paste a URL. Batches take up to 20 files at once - 230+ input formats across video, audio, image, document, and archive types.

02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is a HEIF file?

The High Efficiency Image File Format (HEIF) is a container format defined by MPEG-H Part 12 (ISO/IEC 23008-12) tailored for the storage of individual images and image sequences. It is based on the ISO Base Media File Format (ISOBMFF) and separates the container structure from the image encoding, allowing support for various codecs including HEVC (H.265) and AVC (H.264). HEIF supports computational photography features such as auxiliary image items (depth maps, alpha planes), burst photography, and audio metadata.

How to open a HEIF file

HEIF files are natively supported by modern Apple ecosystems (macOS Mojave+, iOS 11+) and Windows 10/11 via specific system extensions. While identical in structure to HEIC, files explicitly using the .heif extension may contain data encoded with codecs other than HEVC. To view these files on unsupported platforms, cross-platform viewers like XnView MP or image manipulation software like Adobe Photoshop (2020 release and later) are recommended.

What is a GIF file?

The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987, distinguished by its use of the Lempel-Ziv-Welch (LZW) lossless data compression algorithm. It supports up to 8 bits per pixel, allowing a palette of 256 distinct colors selected from the 24-bit RGB color space. The GIF89a specification, introduced in 1989, added support for transparent backgrounds, animation delays, and application extensions, establishing it as a standard for simple web animations and low-color graphics.

How to open a GIF file

GIF files possess near-universal compatibility and can be opened natively by all modern web browsers (Chrome, Firefox, Safari, Edge) and default operating system viewers like Microsoft Photos and Apple Preview. No third-party software is typically required for viewing. For editing frame-by-frame animations or modifying color palettes, raster graphics editors such as GIMP, Adobe Photoshop, or online tools like Ezgif are required.
