What is an online image converter?
An online image converter changes a picture from one file format to another. The Monolith Works converter handles PNG, JPEG, WebP and AVIF, and runs entirely inside your browser — your file is never uploaded to a server. You control quality and dimensions with a live preview, producing images optimised for websites and social media.
How to use it

- 2Choose the target format (WebP, AVIF, PNG, JPEG) and quality level.
- 3Optionally apply a ready-made size preset for Instagram, YouTube or LinkedIn.
- 4Download a single file directly, or several files as a ZIP.
Frequently asked questions
Are my images uploaded to a server?
+
No. Conversion happens entirely inside your browser, on your own device. Your images are never sent to us or to any third party. That is a meaningful security difference for unreleased product shots, design drafts and client material you are not free to share.
Which format should I use for my website?
+
WebP is the balanced default in most cases: noticeably smaller than JPEG and supported by every modern browser. AVIF produces even smaller files but browser support is slightly narrower. For logos and anything needing transparency, use PNG or WebP.
How many images can I convert at once?
+
You can load several images and convert them in one batch. For multiple files, use the "download as ZIP" option — browsers block rapid consecutive downloads, so a single archive is the reliable route.
