Quick guide

Choose by task

Short notes for deciding which converter to open first.

How to choose the right converter category

Start with the format problem you are trying to solve. If the task involves opening, sharing, editing, compressing, or encoding an image, the image converter category is the best place to begin. It includes HEIC, JPG, PNG, WebP, SVG, and Base64 workflows that are common when files move between phones, browsers, design tools, CMS platforms, and developer projects.

Why QuickHeic separates image and data-size tools

Image conversion and file-size conversion are related, but they answer different questions. Image tools change the actual output format, while data-size tools explain what a file size means and how it compares with a limit or specification.

Common workflows that use both categories

A real workflow often crosses categories. For example, you might convert HEIC to JPG because a website does not accept HEIC, and then immediately check whether the new JPG falls under a 2 MB upload cap. In that case, the image tool changes the file and the data-size tool confirms the result.

How to get the most accurate result

Always compare against the requirements of the destination, not just the source file. A phone, operating system, CMS, cloud drive, and upload form can all describe the same file a little differently depending on formatting, accepted types, or unit base.
