Frequently asked questions

How do I convert HEIF to WebP?
Upload your HEIF file above. It is converted to WebP automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.
Does converting HEIF to WebP lose quality?
WebP is lossy by default, so some fine detail is discarded to make the file smaller. Raise the quality or switch on lossless in Settings for a closer copy.
HEIF or WebP: which should I use?
Use HEIF for storing high-quality photos in less space on phones and cameras. Use WebP for websites, online stores and blogs that need fast-loading images. Keep in mind the main drawback of WebP: older apps and some upload forms don't accept it.
HEIFファイルとは?
HEIF is the open standard behind HEIC. Samsung phones and several Canon, Sony and Fujifilm cameras can save HEIF photos, which are compact but not yet widely accepted.

For JPG, WebP, AVIF and image-to-PDF output: higher keeps more detail but makes a bigger file; 60–80 suits most photos. Documents (Publisher, XPS, EPS…) become PDFs with every page and sharp text, with no quality setting.

For WebP and AVIF output: keeps every pixel exactly (best for logos, graphics and transparency) at the cost of a larger file.
