What image formats can I convert between?

The converter supports JPEG, PNG, WebP, SVG, TIFF, AVIF, BMP, GIF, QOI, TGA, EXR, HDR, ICO, PNM, and Farbfeld. Check the formats page for the full conversion matrix.

Will converting change my image quality?

It depends on the formats involved. Converting between lossless formats (PNG, WebP lossless, BMP) preserves every pixel. Converting to a lossy format like JPEG reduces file size at the cost of some quality. You can adjust the quality level before downloading.

Does converting from PNG to JPEG remove transparency?

Yes. JPEG does not support transparency. Transparent pixels will be filled with a white background. Convert to WebP instead if you need to preserve transparency.

Can I convert SVG to PNG or JPEG?

Yes. SVG is supported as an input format and can be converted to PNG, JPEG, WebP, and others. SVG is vector-based so you can scale it to any resolution before converting.

Is there a file size limit?

No fixed limit. Very large images may take longer depending on your device, but there is no server-side restriction.

Can I preview the result before downloading?

Yes. The converter shows a preview of the converted image before you download it, so you can verify the result looks correct.
