When to use Zipora
Use Zipora for an attachment that must be small enough for a form, or when you want to keep selected image contents off a processing server. The Image Compressor exposes quality settings, while Compress Image to 20KB is aimed at a specific byte budget. Both are live tools and do not require an account.
A target-size image can need smaller dimensions as well as stronger compression. Read the result and inspect faces, fine text and edges before uploading it elsewhere. If the receiving service accepts a larger file, preserving more detail can be a better choice than forcing the smallest possible output. Keep your original photograph.
When to use TinyPNG
Use TinyPNG when you need its supported formats or an established optimization workflow beyond a standalone file tool. Its web plans cover AVIF, WebP, PNG and JPEG. If your website needs automated optimization, distinguish the developer API or CDN offering from the web subscription before comparing cost or allowances.
The free web tier has clear session and per-image limits. Paid web subscriptions increase capacity, but do not assume that subscribing also buys an API allowance. Its terms say uploaded images are retained temporarily for processing, with deletion within 48 hours. Review that policy for images you cannot share with a service provider.
Optimize a transparent website logo
Start with the same PNG. Check transparency against a dark background and compare bytes at the same dimensions. If the receiver insists on JPEG under a fixed cap, consider whether a white background is acceptable before using a Zipora size preset.
Try the workflow in Image Compressor.
The verdict
Zipora emphasizes local processing and common attachment targets. TinyPNG offers specialized optimization formats and separate automation products.

Comparison questions
Answers for the task you need today.
Can the 20 KB preset keep transparency?
The preset produces JPEG with a white background. Choose PNG or WebP in the general Image Compressor if the logo needs transparency.
