Frequently Asked Questions
Quick answers about the OneToolBox Image Converter.
Is the Image Converter free?
Yes. The OneToolBox Image Converter is provided as a free online utility.
Which formats can I convert to?
The current converter provides JPG, PNG, WEBP and AVIF output options.
What does the Quality setting do?
The quality slider controls the quality value used during supported image encoding. Higher values generally preserve more image detail while producing a larger output file.
Why do I need a background colour?
Some image formats support transparency while others do not. The converter provides white and black background choices for cases where a background is needed.
Can I preview the converted image?
Yes. After conversion, the result preview shows the converted image along with its new format, dimensions and file size.
Does the converter reduce image quality?
Conversion can change file size and, depending on the selected format and quality, may affect image quality. Use a higher quality value when preserving more detail is important.
Is my image uploaded to OneToolBox?
The current converter code is browser-based and does not include an image-upload request to a OneToolBox server. Processing is performed through client-side JavaScript.
Why might AVIF not work in every browser?
AVIF encoding and decoding support depends on the browser and its underlying image capabilities. If a browser does not support a requested conversion, use JPG, PNG or WEBP.
