Comparison Guide: OKfmt Image Compression as a TinyPNG Alternative

The web version of TinyPNG only supports image compression for 3 formats: PNG, JPG, and WebP. It can process 20 images per operation, with a maximum size of 5MB per single image. Relevant quotas are subject to the current announcement on the official website.

The developers of TinyPNG offer an API service billed by the number of images, which can be integrated into self-developed projects to achieve batch automated compression. This billing model is a distinctive feature of its service.

OKfmt image compression supports image processing for 5 formats: JPG, PNG, WebP, AVIF, and SVG, to meet compression requirements for more formats.

OKfmt supports 30 files in a single batch process, with a maximum size of 50MB per single file. OKfmt also provides tools for image format conversion and subtitle processing.

TinyPNG uses smart lossy quantization as its core compression mechanism. It reduces image file size by adjusting the color quantization ratio of the image, while retaining visually acceptable image quality.

OKfmt image compression uses Sharp re-encoding as its core engine. It compresses file size by re-encoding images, to meet the requirements of different browsers and storage scenarios.

When users only need to compress images in PNG, JPG, or WebP format, and the file size and quantity do not exceed the quota, they can continue to use the web version of TinyPNG.

When users need to compress AVIF or SVG format images, or have single files exceeding 5MB, or batch quantities exceeding the 20-image limit, they can use OKfmt image compression to meet the processing requirements.
