FAQ
Does converting JPG to PNG reduce quality?
PNG uses lossless compression, so no visual quality is lost in the conversion.
Is my file uploaded to a server?
No. ConvertQuick converts files entirely in your browser using the Canvas API. Your JPG file never leaves your device. You can verify this by opening your browser's Network tab and observing that no upload requests are made during conversion.
Is there a file size limit?
There is no server-imposed limit since everything runs locally. The practical limit is your device's memory — most devices can handle images up to 50-100 megapixels without issue.
Can I convert multiple files at once?
Yes. Select or drag multiple JPG files and they will all be converted to PNG in batch. Download each individually or use the download-all button.
