Frequently asked questions
These answers describe this local browser-based converter. It is not a server-side conversion API.
Are JPG files uploaded to imgi.io?
No. The conversion is designed to run in the browser. Files are read locally and exported from Canvas.
What output formats are supported?
The first version supports PNG and WebP. PNG is lossless; WebP can produce smaller files with adjustable quality.
Why not convert JPG to GIF?
Reliable animated GIF encoding is not available through the browser Canvas API without an extra encoder, so GIF is not promised in the first version.
Why can PNG be larger than JPG?
PNG is lossless and stores image data differently. It is often larger than JPG, especially for photos.
Does WebP work in every browser?
The page detects WebP export support. If a browser cannot export WebP, the WebP option is disabled and a clear message is shown.
Can I download everything at once?
Yes. After conversion, Download all creates a ZIP file in your browser with all converted results.
