Image converter FAQ
Everything you need to know about switching image formats in your browser
Is the image converter free to use?
Yes—every converter on imageconverter.dev is free, unlimited, and watermark-free. Convert as many files as you want without creating an account.
Do my images ever upload to a server?
No. All conversions happen entirely in your browser using Web APIs. After the page loads you can even go offline and the converter will keep working.
Will the converter reduce image quality?
We preserve the image resolution and apply gentle compression only when the target format requires it. Transparent backgrounds are automatically flattened to white when exporting to JPG.
Can I convert multiple images at once?
Right now this tool handles one file at a time so you can review the output before downloading. Need bulk conversions? Try our bulk resize tool with format switching support.
