Question 1

Which format is best for photos?

Accepted Answer

WebP offers the best quality-to-size ratio. JPEG is universally supported. PNG is not ideal for photos — files will be much larger.

Question 2

What happens to transparency?

Accepted Answer

JPEG doesn't support transparency. When converting PNG/WebP with transparency to JPEG, you can choose a background fill color (white, black, or custom).

Question 3

Does conversion lose quality?

Accepted Answer

Converting to JPEG or WebP uses lossy compression — adjustable via the quality slider. PNG is lossless but produces larger files.

Question 4

Can I convert multiple images at once?

Accepted Answer

Yes! Add multiple images and convert them all with the same settings. Download individually or as a ZIP.

Question 5

Are my images uploaded?

Accepted Answer

No. All conversion happens locally in your browser using the Canvas API. Nothing leaves your device.
