TinyPNG
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.
