Supported Image Formats — Bulk Image Downloader Pro

Supported image formats matter because image download jobs are rarely as clean as they look. A page might contain JPG photos, WebP product images, PNG logos, SVG icons, GIFs, thumbnails, and CDN URLs with confusing extensions. If you download everything without filtering, the final folder can become noisy fast.

Bulk Image Downloader Pro gives you two different controls that should not be mixed up: file type filtering and image processing. File type filtering helps decide which URLs should be included in a download task. Processing controls what happens to supported images after they are downloaded.

Formats you can target with file type filters

The download task file type controls include common web image formats such as JPG, JPEG, PNG, GIF, WebP, SVG, APNG, AVIF, BMP, SVGZ, and TIFF. This is useful when you only want photos, only want transparent graphics, or want to exclude icons and small decorative files.

Filtering by extension is helpful, but it is not perfect. Some CDNs serve WebP images through URLs that end in .jpg, and some image URLs contain no obvious extension at all. For important jobs, combine file type filters with previewing, dimensions, URL rules, and MIME checks where available.

Formats used for conversion and processing

Conversion is narrower than filtering. The processing workflow uses browser canvas capabilities, and output conversion is limited to JPEG, WebP, or PNG. That means you should not plan a task around converting images into AVIF, TIFF, BMP, or SVG output.

Use JPEG when you want broad compatibility and smaller photo files, WebP when modern web compression matters, and PNG when transparency or lossless output is more important than file size.

When to filter by format

  • Use JPG/JPEG or WebP for product photos, galleries, blog images, and most web photography.
  • Use PNG for transparent graphics, UI screenshots, and images where crisp edges matter.
  • Use GIF or APNG when animated assets are part of the job.
  • Use SVG or SVGZ when you are collecting vector graphics or icons.
  • Use dimensions and URL rules when file type alone cannot separate good images from thumbnails or logos.

How to avoid messy format results

Start broad enough to see what the page actually contains. Then narrow the task. If you only need high-resolution product images, combine format filters with minimum width and height. If you only want images from a product CDN, use domain or URL text filters. If the list came from another source, check broken links and redirects before running a large download.

What not to assume

Do not assume every listed file type can be converted into every other file type. Do not assume a URL extension always matches the real image MIME type. And do not assume embedded images inside documents will be extracted as normal web images. Bulk Image Downloader Pro is strongest when you are working with image URLs and web page image assets, not when trying to unpack unrelated document formats.
