Free image optimization
Upload images and compress them in the same format. Control quality, max file size, and metadata stripping.
Use this tool when you want a smaller file in the same format — for example shrinking a PNG screenshot, a JPEG photo, or a WebP asset before uploading to a CMS or sending by email.
Upload
Upload one or more images in JPG, PNG, WebP, AVIF, TIFF, or GIF.
Adjust
Open advanced settings to set quality, max output size, or PNG compression level. Metadata stripping is enabled by default.
Download
Start processing and download optimized files individually or as a ZIP.
For photographs, quality 70–85 is often a good balance. For graphics with text, prefer PNG level 6–9 or convert to WebP on a dedicated converter page. Use max file size mode when you need a hard KB cap for uploads.
Your browser opens, processes, and prepares your images for download.
Download the converted images before closing the tab. ConvertPort does not keep a copy for you to retrieve later.
