Giới thiệu về công cụ này
Image Converter transforms images between PNG, JPG, WebP and ICO (favicon) formats entirely in your browser. Upload PNG, JPG, WebP, BMP, GIF, SVG, AVIF or TIFF files and export them in the format you need.
Batch-convert dozens of files at once, tune the output quality for lossy formats, flatten transparency onto a background colour for JPG, and optionally cap the maximum dimension to resize on the fly. Download files individually or grab everything as a single ZIP.
Because decoding and encoding use the browser's own canvas, your images never leave your device — nothing is uploaded to a server.

Câu hỏi thường gặp
Which formats can I convert to?
PNG, JPG, WebP and ICO. These are produced by the browser canvas / ICO container.
Which input formats are supported?
Any image the browser can decode: PNG, JPG, WebP, BMP, GIF, SVG, AVIF and (in most browsers) TIFF.
Are my images uploaded anywhere?
No. Decoding and encoding happen locally in your browser; files never leave your device.
Why does JPG lose transparency?
JPG has no alpha channel, so transparent areas are flattened onto the background colour you choose.
