Image converter
Convert images between JPEG, PNG and WebP, several at a time. It runs on your device and uploads nothing. Camera metadata is dropped.
Some sites refuse WebP, some forms want JPEG, and a PNG can be many times larger than it needs to be. Add your images, choose JPEG, PNG or WebP, and download converted copies. It all happens in your browser, so the originals never leave your device.
How it works
- Add up to 12 images by dropping, pasting or choosing them.
- Choose JPEG, PNG or WebP and, for JPEG and WebP, a quality.
- Download each converted file, or all of them at once.
What happens to your data
- Your images are opened and converted by your browser. They are not uploaded to Revault or anywhere else.
- Converted files are new files. Camera data in the originals, such as location, date and device, is not copied into them.
- This page keeps nothing. Close or reload it and your images are gone.
Limits to know about
- Your browser decides which formats it can create. Safari can open WebP but cannot create it, so use Chrome, Edge or Firefox for WebP output.
- HEIC photos from iPhones open in Safari but in most other browsers they do not. If yours will not open, export it as JPEG from your photos app first.
- JPEG cannot be transparent, so transparent areas are filled with a colour you choose. Animated images are converted from their first frame only.
Frequently asked questions
Is converting lossless?
Only to PNG. JPEG and WebP below 100% discard some detail to save space, and re-saving a JPEG again and again loses more each time, so keep your original. Even WebP at 100% from a browser is not guaranteed to be lossless.
Why did my file get bigger?
PNG stores every pixel exactly, so a photo converted to PNG is often much larger. For photographs, JPEG or WebP is usually smaller. PNG suits screenshots, logos and anything that needs transparency.
Why can I not choose WebP in my browser?
Browsers differ in which formats they can create. Safari can show WebP images but cannot save them. When that is the case here, the page says so, and Chrome, Edge or Firefox will do it.
