iHateFiles

iHateFiles is a file converter for images, video and audio that runs entirely in the web browser. Files are converted on the user's own device instead of being uploaded to a server, so there is no upload queue, account or daily cap. It is meant for everyday jobs such as changing a file format, shrinking a file or making a quick edit.

The site lists 63 formats and 969 conversions, including HEIC to JPG, PNG to WEBP, MOV to MP4 and MP4 to MP3, alongside tools to compress, resize, crop and trim files, join videos, extract audio and make GIFs. Other tools remove image backgrounds, read text from images, generate subtitles and split a song into stems, with the AI models running in the browser. Images go through the browser's own decoders and the site's encoders, while video and audio use FFmpeg compiled to WebAssembly.

A typical use is converting an iPhone HEIC photo to JPG, or pulling the audio out of an MP4 as an MP3, without sending the file anywhere. Once the page has loaded it keeps working offline, and it can be installed as a progressive web app.

iHateFiles is free, with no paid tier, watermark or fixed file size limit; the practical limit is the device's memory, and the first video job downloads an engine of about 31 MB. It works in modern browsers on Windows, macOS, Linux, Android and iOS, and accepts voluntary donations.
