Frequently Asked Questions
Which image formats can I convert?
Any image your browser can display, including JPG, PNG, WebP, GIF, BMP and AVIF (in browsers that support it). For HEIC and TIFF use the dedicated converters linked above.
Can I convert multiple images at once?
Yes. Batch conversion is supported, and all results can be downloaded as a single ZIP file.
Does converting change image quality?
Converting to PNG is lossless. Converting to JPG or WebP uses lossy compression; at 85–90% quality the difference is not visible.
Why does my converted JPG have a white background?
JPG cannot store transparency, so transparent pixels are filled with white. Choose PNG or WebP to keep transparency.
Are my images uploaded to a server?
No. Everything is processed locally in your browser. Your files never leave your device, so the tool is safe for private photos and confidential documents.
