About convertimage
Reviewed by the convertimage team · Updated June 2026
convertimage is a free image converter that runs entirely in your web browser. You can convert, compress, and resize multiple images at once without creating an account, installing software, or uploading a single file.
How it works
Most online converters upload your images to a server, process them there, and send the results back. convertimage does not. Every conversion happens locally, using your own device's processor through standard browser technology. Your images are never transmitted, stored, or seen by anyone — including us.
This design has three practical benefits:
- Privacy. Your files stay on your device, so private photos and documents never leave your control.
- Speed. There is no upload or download wait — files are converted as fast as your device can process them.
- No limits. Because we are not paying for server processing, every tool is free, with no file-size cap or watermark.
What you can convert
convertimage supports common image formats including JPG, PNG, WebP, AVIF, GIF, and BMP, with more added over time. You can browse every converter or compare formats to decide which one fits your needs.
Who builds it
convertimage is built and maintained by a small independent team focused on fast, private, no-nonsense web utilities. The site is supported by advertising, which lets us keep every tool free. If you have feedback or spot a problem, please get in touch.
