What happens to your images
When you add an image, your browser reads it from your device into memory. The resizing, compression and conversion all run in JavaScript on your own computer or phone. The finished file is created locally and saved straight to your downloads.
- Images are never sent to a server, so there is nothing for us to store or delete.
- Closing the tab clears everything from memory.
- New files are saved without EXIF metadata such as GPS location.

Common questions
Are my images uploaded?
No. Vexluno's tools process images inside your browser, on your own device. Your images are never sent to our servers or to anyone else. The only network traffic is the website itself being downloaded, like any other web page.
Details are in the Privacy Policy.
Is Vexluno free?
Yes. Every tool is free to use with no limits on how often you use it, and there is nothing to subscribe to.
Do I need an account?
No. There are no accounts and no sign-up. Open a tool, add your images and download the results.
What image formats are supported?
You can add JPG (JPEG), PNG and WebP images, and save results as JPG, PNG or WebP. HEIC, GIF, AVIF and SVG are not supported yet.
Can I compress multiple images at once?
Yes. You can add up to 100 images in one batch. Each one is processed in turn, and you can download them individually or all together as a ZIP file that is also created in your browser.
How much can I reduce an image?
It depends on the image. Large photos straight from a camera or phone often shrink by more than half at the default quality, and resizing them for the web saves much more. Images that were already compressed may barely change. If Vexluno cannot make a file smaller, it gives you back the original instead of a bigger file.
Which format should you use?
Picking the right format often saves more than any compression setting. A quick guide for the three formats Vexluno supports:
| Image | Best format | Why |
|---|---|---|
| Photos for a website | WebP | Smaller than JPG at similar quality, and every modern browser displays it. |
| Photos to email or upload to forms | JPG | Opens in every app and on every device. |
| Logos and icons with transparency | PNG or WebP | Both keep transparent backgrounds; JPG fills them with a colour. |
| Screenshots and diagrams | PNG | Keeps text sharp. Smart PNG compression makes them much smaller. |
