Frequently asked questions
Is it safe to upload my images?
Your image never leaves your device — Image to Base64 processes everything locally in your browser using the HTML5 Canvas API, so nothing is uploaded to a server.
What image formats are supported?
Most tools on this page support PNG, JPG/JPEG, WebP, BMP, GIF and ICO, depending on the specific conversion.
Will I lose quality?
Lossless formats (PNG, BMP) keep full quality; lossy formats (JPG, WebP) use a high default quality setting to minimise visible loss.
Is there a file size limit?
Because everything runs in your browser rather than on a server, the only practical limit is your device's available memory — most everyday images process instantly.
