Quality & file size
Lossy formats (JPEG, WebP, AVIF) trade detail for smaller files as you lower the quality; PNG stays lossless regardless of the slider. The tool always shows the original and result sizes so you can judge the trade-off, and it never recommends a result that is larger than your original as an “optimisation”.
Privacy
Every image is decoded, transformed and re-encoded entirely in your browser using the Canvas API and a Web Worker. Files are never uploaded, are not stored in localStorage, and are cleared from memory when you remove them or close the page.

Common issues & limitations
- JPG cannot store transparency.
- All processing happens on your device; nothing is uploaded, so very large batches are limited by your available memory.
Frequently asked questions
Why convert WebP to JPG?
Some older apps and services do not accept WebP. Converting to JPG maximises compatibility, at the cost of a usually larger file.
What about transparency?
JPG cannot store transparency, so transparent pixels are filled with your chosen background colour.
Are my images uploaded to a server?
No. Every image is decoded, processed and encoded entirely inside your browser using the Canvas API. The files never leave your device and are discarded when you close the page.
