imagetoolbox

Most online converters make you upload your photos to someone else’s server, wait in a queue, and then hand back a file with a watermark or a sign-up wall in front of it. imagetoolbox does the work in your browser instead. Your files never leave your device, so there is nothing to upload and nothing to wait for. Drop a file and it converts within seconds. It handles 63 conversions between image formats, including iPhone HEIC to JPG, PNG, WebP and AVIF. Beyond converting, there are tools to compress an image to fit under a size you pick, resize, crop, rotate, blur or redact parts of a picture, remove location data, make favicons and put a screenshot in a phone frame. PDF tools merge, split and reorder pages and turn images into PDFs and back. Video files can be converted, trimmed and turned into GIFs, also without leaving your device. It is free to use, with no account, no limits and no watermarks. It is made for anyone who needs a file in a different shape right now: a parent whose iPhone photos a school website rejects, a developer who needs a favicon, or someone who has to get a scan under an upload limit.
