Frequently Asked Questions
Are my images uploaded?+
No. Reading, conversion, previews, ZIP creation, and downloads happen in your browser.
Which formats support transparency?+
PNG and WebP support transparency. JPG does not, so transparent pixels use your selected background color.
Does conversion compress automatically?+
No. Optional compression is off by default. Enable it only when you want a smaller JPG or WebP file.
Does conversion resize images?+
No. The original width and height are preserved.
Can JPG be pixel-identical?+
JPG uses lossy encoding by design. With compression off this tool requests maximum browser quality, while PNG output is lossless.
