Frequently Asked Questions

Which image format should I use?

Use JPG for photographs and complex images. Use PNG for graphics, logos, and images requiring transparency. Use WebP for web optimization with the best quality-to-size ratio. Use GIF for simple animations.

Will converting change my image quality?

Converting between lossless formats (PNG, BMP) preserves quality. Converting to JPG uses compression and may slightly reduce quality, optimized for a good balance. WebP provides excellent quality with smaller sizes.

Can I convert animated GIFs?

Converting an animated GIF to other formats will result in a static image (first frame). To preserve animation, keep the GIF format or convert to video formats using our Video tools.

What happens to transparent backgrounds?

Transparency is preserved when converting to PNG, WebP, or GIF. When converting to JPG or BMP (which don't support transparency), transparent areas become white.

What's the maximum file size I can convert?

You can convert images up to 20MB in size. There's no daily limit on the number of conversions - convert as many images as you need for free.
