Frequently asked questions
Are my images uploaded anywhere?
No. Editing uses the browser Canvas API, so every operation runs locally on your device and the original bytes are never sent to a server.
How much can I compress before quality drops?
Use the quality slider with the live size preview. WebP typically saves 25-35% over JPEG at similar perceptual quality.
Can I resize to exact pixel dimensions?
Yes. Enter width and height (optionally lock the aspect ratio) and the image is rescaled on export.
Does it support transparent PNGs?
Yes. Keep PNG to preserve transparency, or convert to WebP for smaller files with alpha support.
