Image Converter

Image Converter delivers exactly what its name promises, convert images between any formats, png, jpg, webp, avif, jpeg-xl, heic, gif, bmp and tiff, free in your browser. batch convert and download as zip, fast and free. Because it belongs to ToolsMonk's image tools collection, the whole workflow happens on a single page instead of being spread across separate apps or websites.

Typical jobs it handles include turning iphone heic photos into jpg or png so they open on windows and older software, converting a folder of pngs to webp or avif to cut page weight before uploading to a site, and producing a jpg copy of a design for a form or portal that refuses to accept anything else. The same page works on desktop, tablet, and mobile, so it is equally quick for a single urgent task and for work you repeat every week.

Image Converter is designed for people who want a practical, privacy-friendly workflow with instant results inside the larger ToolsMonk library.

The Image Converter turns any common image format into any other, in your browser, with no upload. It handles PNG, JPG, WebP, AVIF, JPEG-XL, HEIC, GIF, BMP and TIFF, in every direction, one file at a time or a whole folder at once.

The most common reason people arrive here is HEIC. Every iPhone shoots HEIC by default, and Windows, many web forms and a lot of older software cannot open it. Dropping the files in and converting to JPG solves that in one step, and because nothing is uploaded, the location data embedded in holiday photos never leaves your laptop.

The second common reason is page weight. WebP and AVIF were designed for the web and reliably beat JPG at the same visual quality, often by a third or more. If you are preparing images for a site, convert to WebP, set the quality around 80, and compare: in most photographs the difference is invisible while the file is dramatically smaller.

It helps to know which formats are lossless and which are not. PNG and lossless WebP keep every pixel exactly. JPG, AVIF and standard WebP discard detail to save space, and the quality slider decides how much. That matters if you convert repeatedly, because each lossy save compounds the loss. Keep the original and convert from it each time rather than converting a converted file.

Transparency is the other thing worth planning for. PNG, WebP and AVIF carry an alpha channel; JPG does not. Converting a transparent PNG to JPG has to put something behind the transparent pixels, and that something is white. If you need the transparency, pick a format that supports it.

Everything runs on your own device using the browser's own image pipeline, so there is no upload, no queue and no size limit beyond your machine's memory. On very large batches it is worth working in a few smaller runs so you can start downloading while the rest converts.
