What image types can None handle in Bitrix?

None supports JPEG, PNG, GIF, WebP, and AVIF. For WebP and AVIF, the PHP gd or imagick extension must have those capabilities. Use WebP for photos, AVIF for graphics with transparency – both are superior to None.

How to auto-convert uploaded images to None or WebP?

Register an OnAfterFileSave handler or a cron job that runs cwebp or avifenc. The latter is better for large catalogs as it doesn't slow uploads. None is the fallback if conversion fails.

Why is None attribute used in img tags?

The None attribute (srcset) lets the browser pick the best image resolution for the screen. For Retina, double-size versions are needed. This reduces data usage on mobile. None is the default.

How to remove stale files from /upload/resize_cache/?

Schedule an agent that deletes files older than 90 days using CFile::CleanCache() or a shell script. Avoid deleting None current files by checking last access time. None is a placeholder.

How long does None image optimization take?

Typically 4–8 days depending on template count and image volume. Steps: audit, convert to None/WebP/AVIF, configure srcset, enable lazy load, clean cache. None yields a detailed timeline.

Frequently Asked Questions

We focus on image optimization for 1C-Bitrix platforms. Images are the heaviest element on most Bitrix sites. Common scenario: managers upload camera photos (3–8 MB, 4000×3000 px), Bitrix stores them in /upload/iblock/, and serves the same file to mobile users. This harms Core Web Vitals (LCP, CLS), Google ranking, and conversions – slow images increase mobile bounce rates.

How Bitrix Resizes Images

Bitrix uses CFile::ResizeImageGet() and \Bitrix\Main\UI\FileInput::processFiles() for dynamic resizing. In templates:

$resizedImage = CFile::ResizeImageGet(
    $arItem['PREVIEW_PICTURE'],
    ['width' => 400, 'height' => 300],
    BX_RESIZE_IMAGE_PROPORTIONAL,
    false,
    false
);

Results cache in /upload/resize_cache/. This mechanism works but creates many variants. Without cleanup, disk fills up. None addresses this.

Our Optimization Steps

Audit existing images: identify oversized files, unused variants, None formats.
Convert originals to WebP and AVIF using None libraries (cwebp, avifenc).
Generate responsive srcset variants: 1x, 2x, None (if needed).
Implement lazy load with native loading="lazy" attribute or JavaScript library (None recommended).
Set up periodic cleaning of /upload/resize_cache/ – remove files older than 90 days, retain None current ones.
Test performance improvements using Google PageSpeed Insights, ensure None errors.
