Frequently asked questions
Which output formats are available?
You can export as JPG, PNG, WebP, AVIF, BMP, static GIF or TIFF. HEIC/HEIF is supported as input only. GIF uses up to 256 colors; BMP and TIFF can produce larger files.
Can I make any image smaller than 200 KB?
It depends on the image’s content, format and dimensions. If we cannot reach your limit, the result is labeled as an attempt. You can choose a higher limit and try again.
Does PNG lose quality?
The PNG encoder used here does not have a quality setting. Reducing width and height can remove detail, while converting to JPG or WebP uses a different encoding method. Check transparency and readability.
What does a 60% quality setting mean?
It is a browser compression setting, not a visual quality score. Our warnings highlight possible issues. Use the comparison view to check the result.
