Fastly Image Optimizer vs TinyPNG

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.

TinyPNG is an image compression service offering lossy compression, batch processing, resizing, metadata controls and API access. It supports JPEG XL, AVIF, WebP, JPG, PNG and APNG files. Free web use allows up to 20 image compressions per session, with each image limited to 5 MB, and up to three conversions per session. The API includes 500 free compressions each month; unused free compressions reset at the start of each calendar month and do not roll over. Above that allowance, charges apply to successful compressions, with no subscription fee or minimum charge. Uploaded images are accessible only to the uploader and retained for a maximum of 48 hours. TinyPNG removes unnecessary metadata, while the API can preserve selected copyright, location and creation-date metadata. Official plugins are available for WordPress and Figma, alongside a beta Zapier integration. Web Pro offers unlimited compressions and a 75 MB per-image limit, while Web Ultra allows 150 MB images and unlimited conversions. The maker is headquartered in Hoevelaken, Netherlands.
