About the Image Format Converter
Different platforms want different formats. Convert a screenshot to JPEG, a photo to WebP or a transparent logo to PNG, with a background colour for formats that cannot store transparency.

Why use this image format converter?
- Nothing leaves your device. The work happens in your browser tab. There is no upload endpoint in this app, so your files and text cannot be stored, logged or seen by us.
- No upload wait. You skip the round trip to a server entirely. Results are limited by your own CPU, not by network speed or queue size.
- Free, no account, no quotas. No sign-up wall, no watermark, no daily limit. Optional accounts only exist to save favourites and presets across devices.
Frequently asked questions
Is my image safe to use here?
Yes. This tool runs entirely in your browser using JavaScript. Nothing you paste or open is sent to a server, and the page keeps no copy after you close it.
Do I need to create an account?
No. Every tool is fully usable without signing in. An account only adds saved favourites and reusable presets.
Does it work on a phone?
Yes. The interface is mobile-first with large touch targets and a stacked layout, so it works on phones and tablets as well as desktops.
Which format should I use?
PNG for logos, screenshots and anything with transparency; JPEG for photographs that need maximum compatibility; WebP for websites where every kilobyte matters.
Why did my transparent background turn white?
JPEG cannot store transparency. The converter fills transparent areas with the background colour you choose, white by default.
