Media - Nitrol Docs

Image processing, upload controls, and media file management. These settings let you fine-tune how WordPress handles files when they're uploaded and served.

#Upload Formats

WordPress restricts which file types can be uploaded to the media library by default. These settings unlock modern formats:

Setting	What it does	Rec
Allow SVG Uploads	Enables `.svg` file uploads - lets editors use vector graphics and logos	Yes
Allow WebP Uploads	Enables `.webp` file uploads - the modern compressed image format	Yes
Allow AVIF Uploads	Enables `.avif` file uploads - next-gen format with even better compression	-

SVG support also adds sanitization - uploaded SVG files are scanned and cleaned before saving to remove potentially malicious code.

#Image Processing

Control how WordPress processes images after upload:

Setting	What it does
Disable Big Image Scaling	Prevents WordPress from automatically downscaling images larger than 2560px
Disable Image Sizes	Select which auto-generated thumbnail sizes to skip (`medium_large`, `1536x1536`, `2048x2048`)
Progressive JPEG	Enables interlaced JPEG encoding - images render progressively instead of top-to-bottom
Disable PDF Thumbnails	Stops WordPress from generating preview images for PDF uploads

Disabling the 1536x1536 and 2048x2048 sizes is a good default for most sites - WordPress generates these for the block editor but they're rarely needed if you're using a page builder or classic editor.

#Upload Settings

Setting	What it does
Clean Media Filenames	Strips accents and special characters from filenames on upload (e.g. `résumé.pdf` > `resume.pdf`)
Custom Upload Limit	Override the server max upload size - choose from 2, 5, 10, 25, 50, or 100 MB

Clean Media Filenames is especially useful for sites with multilingual content or editors who upload files with spaces and special characters - it prevents broken URLs and improves compatibility.

#Redirects

Setting	What it does	Rec
Disable Attachment Pages	Redirects attachment URLs (e.g. `/my-image/`) to the parent post with a 301	Yes
Disable Image Hotlinking	Blocks external sites from embedding your images directly, protecting your bandwidth	-

Disabling attachment pages is strongly recommended - they serve thin content (just an image and title) that can hurt your SEO. The 301 redirect sends visitors and search engines to the actual post instead.
