Which image tool do I need?
If a photo from an iPhone will not open, start with HEIC to JPG. If you saved an image from a website and got a .webp or .avif file, use WebP to JPG or AVIF to JPG, or the PNG versions if the image has a transparent background. Building a website? JPG to WebP makes images lighter. Need a file under a size limit for email or a form? Compress image finds the best quality that fits. The general image converter does all of the above from one page.
How the image tools work
Your browser already knows how to decode most image formats and how to encode JPG, PNG and usually WebP. Myriadfile uses those built-in abilities through the Canvas API, plus an open-source HEIC decoder for iPhone photos and an open-source PDF library for PDF output. All of them are hosted on this site and run inside your browser tab. See how it works for the details.
Converted images are saved without EXIF metadata, so GPS location and camera details are removed, while rotation is applied to the pixels.
