Question 1

Does this tool upload my image?

Accepted Answer

No. Image Converter runs entirely in your browser using the Canvas API. Your file never leaves your device.

Question 2

Which formats are supported?

Accepted Answer

JPG/JPEG, PNG, WebP, and AVIF — in both directions. AVIF and WebP encoding require a recent browser (Chrome, Edge, Firefox 113+, or Safari 16+).

Question 3

What happens to transparency when I convert to JPG?

Accepted Answer

JPG does not support transparency. If your source image has transparent areas, they will be flattened against a solid background color (white by default) before encoding.

Question 4

When should I adjust the quality slider?

Accepted Answer

Quality controls apply to JPG, WebP, and AVIF (all lossy formats). Higher values keep more detail but produce larger files. PNG is lossless — the quality slider is hidden for PNG output.

Question 5

Will converting change the image dimensions?

Accepted Answer

No. Image Converter preserves the original pixel dimensions. To change the size, use the Resize Image tool.

Question 6

PNG to JPG makes files smaller — is that normal?

Accepted Answer

Yes. JPG uses lossy compression and no alpha channel, so photographs typically get much smaller when converted from PNG. For graphics with sharp edges or transparency, keep them as PNG or WebP.
