Pro Tips for Convert Image
Get the most out of your convert image experience
HEIC photos
Safari decodes HEIC natively. On other browsers, export from your phone as JPG first.
SVG
Vector SVGs are rasterised at the size you choose. Increase the scale for sharper output.
Transparency
Only PNG and WebP keep transparency. JPG fills it with your chosen background colour.

Frequently Asked Questions — Convert Image
Everything you need to know about how to convert image online
Which formats can I convert to?
JPG, PNG and WebP, the formats every browser can encode.
Is quality lost?
PNG output is lossless. JPG and WebP are lossy at the quality you choose; 90+ is near-lossless.
Are my files secure while I convert images?
Yes. Everything happens inside your browser using JavaScript and WebAssembly. Your file is never uploaded, and nothing is stored on a server.
Do you keep a copy of my document?
No. The file lives in your browser's memory only. When you close or refresh the tab it is gone. We cannot see it, and neither can anyone else.
