Frequently asked questions
Are my JPG images uploaded?
All work happens locally in the browser; no upload is required.
Can I convert JPG to JPEG online?
Yes. This page opens the converter with JPEG selected as the output format.
Will the file size change after conversion?
JPEG output can be smaller or larger depending on compression, transparency, colors, and image dimensions.
Can I control output quality?
Quality control is available for JPG, JPEG, and WebP output. PNG, BMP, TIFF, GIF, and ICO have different export behavior.
Does conversion keep transparency?
PNG and WebP can preserve transparency. JPEG/JPG output uses a background because JPEG does not support alpha transparency.
Why can very large images fail?
Browsers limit memory and canvas size. Try smaller dimensions or fewer files if conversion fails.
