Web media tools.

Image Compressor

Shrink image file sizes for faster websites without visibly losing quality. Drop your images and Optimeaux re-encodes them locally at web-friendly quality — nothing is uploaded.

Image Resizer

Resize images to the exact dimensions your website actually displays. Set a max width or exact size, preserve aspect ratio, and never accidentally upscale. Everything runs locally.

Bulk Image Resizer

Resize a whole folder of images in one pass. Apply the same max width to every file, preserve aspect ratios, bulk rename the output, and download everything as a ZIP — all in your browser.

PNG to WebP Converter

Convert PNG images to smaller WebP files while preserving transparency. WebP offers dramatically smaller files than PNG for the same visual quality — and it works everywhere modern browsers do.

JPG to WebP Converter

Convert JPEG photos to smaller WebP files for faster websites. WebP typically produces 25–35% smaller files than JPEG at the same visual quality — a quick win for page speed.

Image to AVIF Converter

Convert images to AVIF — the most efficient modern image format — for the smallest possible web files. Optimeaux only offers AVIF output when your browser supports encoding it, so you never get a broken file.

Video Compressor

Compress video files for faster websites. Convert to efficient H.264 MP4 or VP9 WebM, remove audio for background loops, and add fast-start metadata — all processed locally in your browser.

Web Video Optimizer

Prepare video for production websites with purpose-built presets: Website Hero, Background Loop, and Mobile Background. Each produces fast-start H.264 MP4 with the right resolution and audio behavior — locally.

Bulk File Renamer

Rename many files at once with a base name, auto-numbering with padding, search-and-replace, and SEO-safe cleaning. See a full live preview before processing, and preserve the correct extension for every file type.
