How it works
A useful result,
without the upload.
Convert JPG, PNG and WebP images entirely in the browser, with transparent-background handling and adjustable quality. The file is decoded and processed inside this browser tab, so File Preflight never receives its contents.
LOCAL METHODBrowser canvas decode → selected image encoding
Worked example
Convert a transparent PNG to WebP for a smaller web preview, or flatten it to white for a JPG export.
Before you send the file
- JPEG does not support transparency, so transparent pixels are placed on white.
- Repeated lossy conversion can reduce quality.
- Color profiles and some metadata may not be preserved by browser canvas export.
