What is TinyPNG? TinyPNG Review, Features

TinyPNG is an online image compression cloud application from abroad, which is completely free and does not require registration. The compression method used by TinyPNG is lossy compression, which means that after the PNG image you upload is compressed, some color information will be lost.

About TinyPNG

TinyPNG can compress PNG to within 1/3 while maintaining the alpha channel, and the loss of compression is basically indistinguishable to the naked eye. Unfortunately, it only supports uploading PNG images to the official website for compression and then downloading. However, TinyPNG provides developers API, which is also based on HTTP. The free version can compress 500 images per month. The paid version supports more than 3,500 images per month.

principle

Use intelligent lossless compression technology to reduce the size of image files. By intelligently selecting the number of colors, the storage bytes are reduced, but the effect is basically the same as before compression.

After batch compressing pictures, package download is supported for up to 10 compressed pictures. Downloading is not allowed for more pictures. If there are any BUGs, please contact the webmaster for feedback.

Supported formats

Online image compression, supports [.jpg], [.jpeg], [.png], [.bmp], and [.webp] formats.

use

After uploading a 24-bit PNG image, it will be compressed into an 8-bit PNG image. This is how the 70% compression rate comes from. If you look at the image carefully, you can still find that it is different from the original image, especially the gradient transition.

Development History

- In 2014, TinyPNG added smart compression for JPEG images.

-In 2016, TinyPNG added support for animated PNGs.
