Frequently Asked Questions
Which format is best for the web?
WEBP usually gives the smallest file size at a quality close to JPEG, and is supported by most modern browsers; if you need broader compatibility with older software, JPEG or PNG is a safer choice.
When should I use PNG instead of JPG?
PNG is better for images with text, sharp lines, or a transparent background, since it loses no detail, while JPG is better suited for photographic images with gradual color tones.
Does converting the format change the image dimensions?
No, converting only changes how the image data is stored — the width and height stay exactly the same.
Can I convert several images with different formats at once?
Yes, you can upload images with different formats (like JPG and PNG together) and convert them all to the same new format in one operation.
Does the file size change after conversion?
Yes, file size varies depending on the new format; WEBP and JPG usually give a smaller size than PNG.
Does the tool support iPhone's HEIC format?
Not currently; the tool only supports JPG, PNG, and WEBP as input and output formats.
Are my images uploaded to a server?
No, the conversion happens entirely inside your browser using Canvas, and no image is uploaded to an external server.
