In their own words
Fastly Image Optimizer
Fastly Image Optimizer automates image processing and delivery for image-heavy sites and apps. It resizes, adjusts quality, crops or trims, changes orientation, converts formats, and serves images on demand at the edge. Transformations are made in real time from request parameters, avoiding the need to pre-generate and store multiple variants. Processed images are cached for reuse. Supported formats are WebP, AVIF, JPEG, and PNG; developers control resizing, quality, format, and cropping through query parameters and configuration. The service integrates with existing asset pipelines and CMS platforms while teams keep their current image sources. It can be enabled through the Fastly control panel or API, while Compute SDK access is available through a beta program. Pricing includes 100,000 image requests per month at free. Paid rates are billed per 10,000 image requests and vary by monthly volume, from $0.50 a month for 100,000–10 million requests to $0.01 a month beyond 5 billion. Every request sent to Image Optimizer, including through the SDK, counts as billable.
MumenLabs Image Compressor
MumenLabs Image Compressor is a browser tool for compressing, resizing, and converting images locally on a device. It accepts JPG, PNG, WebP, GIF, and HEIC files, and converts among JPG, PNG, WebP, and HEIC. Compression can use an adjustable quality setting or a target size such as under 100KB or 1MB. Resizing supports exact pixels, percentages, and presets for Instagram, TikTok, YouTube, Facebook, X, LinkedIn, and Pinterest. A metadata option removes EXIF and GPS details before download. Batch processing is supported, with PNG and ICO export, app icon sets, and web manifest support. MumenLabs says files are processed in the browser, never uploaded, and remain usable offline after loading. The tool works in desktop and mobile browsers without a download, app, plugin, or extension. The Free plan costs nothing, requires no account, and has no watermark, batch limit, size limit, or daily quota; hardware is the practical constraint.
