FAQ
Will there be quality loss after conversion?
It depends on the target format. Lossless formats (like PNG, lossless WebP) preserve quality, while lossy formats (like JPG) may have slight loss, but we use high-quality settings to minimize it.
How is transparent background handled?
When converting to PNG or WebP, transparent backgrounds are preserved. When converting to JPG, transparent areas are replaced with white background, as JPG does not support transparency.
Can I convert multiple images at once?
Yes, you can select multiple images at once for batch conversion. All images are processed locally in your browser without uploading to any server.
Are my files uploaded to a server?
No. All conversions are done locally in your browser, and files are never uploaded to any server. Your privacy and data security are fully protected.
What image formats are supported?
We support conversion between common image formats including JPG, PNG, WebP, HEIC, ICO and more. Each format has its unique advantages for different use cases.
